4. CLINICAL PARTICULARS
4.1 Therapeutic indications
Pravafenix is indicated as an adjunct to diet and other non-pharmacological treatment (e.g. exercise,weight reduction) for the treatment of mixed hyperlipidaemia in adult patients at high cardiovascularrisk to reduce triglycerides and increase HDL-C when LDL-C levels are adequately controlled whileon a treatment with pravastatin 40 mg monotherapy.
4.2 Posology and method of administration
Prior to initiating Pravafenix, secondary causes of combined dyslipidaemia should be excluded andpatients should be placed on a standard cholesterol and triglycerides-lowering diet which should becontinued during treatment.
PosologyThe recommended dose is one capsule per day. Dietary restrictions instituted before therapy should becontinued.
Response to therapy should be monitored by determination of serum lipid values. Rapid reduction ofserum lipid levels usually follows Pravafenix treatment, but treatment should be discontinued if anadequate response has not been achieved within three months.
Special populationsElderly patients (≥ 65 years old)
Treatment initiation with Pravafenix should be decided after renal function has been evaluated (seesection 4.4 Renal and urinary disorders). Limited safety data on Pravafenix is available in patients >75years of age and care should be exercised.
Renal impairmentPravafenix is contraindicated in patients with moderate to severe renal impairment (defined as acreatinine clearance < 60 ml/min) (see section 4.3.)
No modification of posology should be necessary in patients with mild renal impairment.
Hepatic impairmentPravafenix is not recommended in patients with moderate hepatic impairment and is contraindicated inpatients with severe hepatic impairment (see section 4.3.). No posology adjustment is required inpatients with mild hepatic impairment.
Paediatric population (< 18 years old)
There is no relevant use of Pravafenix in the paediatric population (< 18 years old) for the indicationof mixed dyslipidaemia (see section 4.3).
Method of administrationOral use.
The recommended dose is one capsule taken daily during the evening meal. Since it is less wellabsorbed from an empty stomach, Pravafenix should always be taken with food (see sections 4.5. and5.2).
4.3 Contraindications
- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.
- Severe hepatic impairment including biliary cirrhosis or active liver disease including unexplainedpersistent elevations in liver function tests (including serum transaminase elevation) exceeding 3fold the upper limit of normal (ULN) (see section 4.4).
- Children and adolescents (age below 18 years).
- Moderate to severe renal impairment (defined as an estimated creatinine clearance < 60 ml/min).
- Known photo allergy or photo toxic reaction during treatment with fibrates or ketoprofen.
- Gallbladder disease (see section 4.4).
- Chronic or acute pancreatitis with the exception of acute pancreatitis due to severehypertriglyceridaemia (see section 4.4).
- Pregnancy and breast-feeding (see section 4.6).
- Personal history of myopathy and/or rhabdomyolysis with statins and/or fibrates or confirmedcreatine phosphokinase (CK) elevation above 5 times the ULN under previous statin treatment(see section 4.4).
4.4 Special warnings and precautions for use
The pharmacokinetics properties of Pravafenix are not completely identical to the co-administration ofthe existing monotherapies when taken with fat-meal or in fasting state. Patients should not beswitched from a free co-administration of fenofibrate and pravastatin preparation to Pravafenix (seesection 5.2.).
Musculoskeletal and connective tissue disordersAs with other lipid lowering substances, pravastatin or fenofibrate have been associated with the onsetof myalgia, myopathy and very rarely rhabdomyolysis with or without secondary renal insufficiency.
Rhabdomyolysis is an acute potentially fatal condition of skeletal muscle, which may develop at anytime during treatment and is characterised by massive muscle destruction associated with majorincrease in CK (usually > 30 or 40 times the ULN) leading to myoglobinuria.
The risk of muscle toxicity is increased when a fibrate and a 3-hydroxy-3-methyl-glutaryl-
Coenzyme A (HMG-CoA) reductase inhibitor are administered together. Myopathy must beconsidered in any patient presenting with unexplained muscle symptoms such as pain or tenderness,muscle weakness, or muscle cramps. In such cases CK levels should be measured (see below).
Consequently, the potential benefit/risk ratio of Pravafenix should be closely assessed before treatmentinitiation and patients should be monitored for any signs of muscle toxicity. Certain predisposingfactors such as age > 70, renal impairment, hepatic impairment, hypothyroidism, personal history ofmuscular toxicity with a statin or fibrate, personal or familial history of hereditary muscular disordersor alcohol abuse may increase the risk of muscular toxicity and therefore CK measurement is indicatedbefore starting the combination therapy in these patients (see below).
Statins including pravastatin must not be co-administered with systemic formulations of fusidic acid orwithin 7 days of stopping fusidic acid treatment. In patients where the use of systemic fusidic acid isconsidered essential, statin treatment should be discontinued throughout the duration of fusidic acidtreatment. There have been reports of rhabdomyolysis (including some fatalities) in patients receivingfusidic acid and statins in combination (see section 4.5). The patient should be advised to seek medicaladvice immediately if they experience any symptoms of muscle weakness, pain or tenderness.
Statin therapy may be re-introduced seven days after the last dose of fusidic acid.
In exceptional circumstances, where prolonged systemic fusidic acid is needed, e.g., for the treatmentof severe infections, the need for co-administration of Pravafenix and fusidic acid should only beconsidered on a case by case basis and under close medical supervision.
Before treatment initiation
CK levels should be measured prior to initiation of therapy. The baseline CK levels may also be usefulas a reference in the event of a later increase during the combination therapy. When measured, CKlevels should be interpreted in the context of other potential factors that can cause transient muscledamage, such as strenuous exercise or muscle trauma and repeated if necessary.
If CK levels are significantly elevated > 5 times the ULN at baseline, the results should be controlledafter 5-7 days. If confirmed, the treatment should definitively not be initiated (see section 4.3).
During treatmentRoutine monitoring of CK is systematically recommended every 3 months during the first 12 monthsof the combination therapy and let to the appreciation of the clinician beyond this initial period.
Patients should be advised to report promptly unexplained muscle pain, tenderness, weakness orcramps. In these cases, CK levels should be measured.
If a markedly elevated (> 5 times the ULN) CK level is detected and confirmed, Pravafenix therapymust be discontinued. Treatment discontinuation should also be considered if the muscular symptomsare severe and cause daily discomfort (whatever CK levels). If a hereditary muscular disease issuspected in such patients, restarting Pravafenix therapy is not recommended.
There have been very rare reports of an immune-mediated necrotizing myopathy (IMNM) during orafter treatment with some statins. IMNM is clinically characterized by persistent proximal muscleweakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment.
Hepatobiliary disordersAs with other lipid lowering medicinal products, moderate increases in transaminase levels have beenreported in some patients treated with pravastatin or fenofibrate. In the majority of cases, livertransaminase levels have returned to their baseline value without the need for treatmentdiscontinuation.
It is recommended that transaminase levels be monitored every 3 months during the first 12 months oftreatment and let to the appreciation of the clinician beyond this initial period.
Special attention should be paid to patients who develop increase in transaminase levels and therapyshould be discontinued if increases in aspartate aminotransferase (AST) and alanine aminotransferase(ALT) exceed 3 times the ULN and persist.
Caution should be exercised when Pravafenix is administered to patients with a history of liver diseaseor heavy alcohol ingestion.
PancreatitisPancreatitis has been reported in patients taking fenofibrate or pravastatin (see sections 4.3). Thisoccurrence may represent a failure of efficacy in patients with severe hypertriglyceridaemia, a directmedicinal product effect, or a secondary phenomenon mediated through biliary tract stone or sludgeformation, resulting in the obstruction of the common bile duct.
Renal and urinary disordersPravafenix is contraindicated in moderate to severe renal impairment (section 4.3).
It is recommended to systematically assess the estimated creatinine clearance at the initiation of thetreatment and every 3 months during the first 12 months of the combination therapy then let to theappreciation of the clinician beyond this period.
Treatment should be discontinued in case of an estimated creatinine clearance < 60 ml/min.
Interstitial lung diseaseExceptional cases of interstitial lung disease have been reported with some statins, especially withlong term therapy (see section 4.8). Presenting features can include dyspnoea, non-productive coughand deterioration in general health (fatigue, weight loss and fever). If it is suspected a patient hasdeveloped interstitial lung disease, Pravafenix therapy should be discontinued.
CholelithiasisFenofibrate may increase cholesterol excretion into the bile, potentially leading to cholelithiasis. Ifcholelithiasis is suspected, gallbladder studies are indicated. Pravafenix should be discontinued ifgallstones are found.
Venothromboembolic events
In the FIELD study, a statistically significant increase was reported in the incidence of pulmonaryembolism (0.7% in the placebo group versus 1.1% in the fenofibrate group; p=0.022) and astatistically non significant increase in deep vein thrombosis (placebo 1.0% 48/4,900 patients) versusfenofibrate 1.4% (67/4,895); p=0.074. The increased risk of venous thrombotic events may be relatedto the increased homocysteine level, a risk factor for thrombosis and other unidentified factors. Theclinical significance of this is not clear. Therefore, caution should be exercised in patients with historyof pulmonary embolism.
Diabetes Mellitus
Some evidence suggests that statins as a class raise blood glucose and in some patients, at high risk offuture diabetes, may produce a level of hyperglycaemia where formal diabetes care is appropriate.
This risk, however, is outweighed by the reduction in vascular risk with statins and therefore shouldnot be a reason for stopping statin treatment. Patients at risk (fasting glucose 5.6 to 6.9 mmol/L,
BMI>30kg/m 2, raised triglycerides, hypertension) should be monitored both clinically andbiochemically according to national guidelines.
Concomitant use with glecaprevir/pibrentasvir
The use of Pravafenix is not recommended in patients treated with glecaprevir/pibrentasvir.
Concomitant use of pravastatin and glecaprevir/pibrentasvir may increase the plasma concentration ofpravastatin and may lead to an increase of dose-dependent adverse events including myopathy risk.
Patients treated with glecaprevir/pibrentasvir should not exceed 20 mg per day of pravastatin.
LactoseThis medicinal product contains lactose. Patients with rare hereditary problems of galactoseintolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
SodiumThis medicinal product contains 33.3 mg sodium per capsule (excipients and active substance),equivalent to 1.7% of the WHO recommended maximum daily intake of 2 g sodium for an adult.
4.5 Interaction with other medicinal products and other forms of interaction
There have been no formal interaction studies for Pravafenix; however the concomitant use of theactive substances in patients in clinical studies has not resulted in any unexpected interactions. Thefollowing statements reflect the information available on the individual active substances (fenofibrateand pravastatin).
Interactions relevant to pravastatin
Colestyramine/Colestipol
Concomitant administration resulted in approximately 40 to 50% decrease in the bioavailability ofpravastatin. There was no clinically significant decrease in bioavailability or therapeutic effect whenpravastatin was administered one hour before or four hours after colestyramine or one hour beforecolestipol.
CiclosporinConcomitant administration of pravastatin and ciclosporin leads to an approximately 4 fold increase inpravastatin systemic exposure. In some patients, however, the increase in pravastatin exposure may belarger. Clinical and biochemical monitoring of patients receiving this combination is recommended.
Medicinal products metabolised by cytochrome P450
Pravastatin is not metabolised to a clinically significant extent by the cytochrome P450 system. This iswhy medicinal products that are metabolised by, or are inhibitors of, the cytochrome P450 system canbe added to a stable regimen of pravastatin without causing significant changes in the plasma levels ofpravastatin, as have been seen with other statins. The absence of a significant pharmacokineticinteraction with pravastatin has been specifically demonstrated for several medicinal products,particularly those that are substrates/inhibitors of CYP3A4 e.g. diltiazem, verapamil, itraconazole,ketoconazole, protease inhibitors, grapefruit juice and CYP2C9 inhibitors (e.g. fluconazole).
In one of two interaction studies with pravastatin and erythromycin a statistically significant increasein the area under the curve (AUC) (70%) and Cmax (121%) of pravastatin was observed. In a similarstudy with clarithromycin a statistically significant increase in AUC (110%) and Cmax (127%) wasobserved. Although these changes were minor, caution should be exercised when associatingpravastatin with erythromycin or clarithromycin.
Fusidic acid
The risk of myopathy including rhabdomyolysis may be increased by the concomitant administrationof systemic fusidic acid with statins. The mechanism of this interaction (whether it ispharmacodynamic or pharmacokinetic, or both) is yet unknown. There have been reports ofrhabdomyolysis (including some fatalities) in patients receiving this combination.
If treatment with systemic fusidic acid is necessary, pravastatin treatment should be discontinuedthroughout the duration of the fusidic acid treatment. Also see section 4.4.
Glecaprevir/pibrentasvir
Concomitant use of pravastatin and glecaprevir/pibrentasvir may increase the plasma concentration ofpravastatin and may lead to an increase of dose-dependent adverse events including myopathy risk.
Patients treated with glecaprevir/pibrentasvir should not exceed 20 mg per day of pravastatin.
Therefore Pravafenix is not recommended in those patients.
Other medicinal products
In interaction studies, no statistically significant differences in bioavailability were observed whenpravastatin was administered with acetylsalicylic acid, antacids (when given one hour prior topravastatin), nicotinic acid or probucol.
Interactions relevant to fenofibrate
Bile acid resin
Bile acid binding resins frequently reduce the absorption of medicinal products and when resins arebeing co-administered, fenofibrate should be taken 1 hour before, or 4 to 6 hours after, the resin so asnot to impede the absorption of fenofibrate.
Oral anticoagulants
Fenofibrate enhances oral anticoagulant effect and may increase risk of bleeding. It is recommendedthat the dose of anticoagulants is reduced by about one third at the start of treatment and thengradually adjusted if necessary according to INR (International Normalised Ratio) monitoring. Thiscombination is, therefore, not recommended.
CiclosporinSome severe cases of reversible renal function impairment have been reported during concomitantadministration of fenofibrate and ciclosporin. The renal function of these patients must therefore beclosely monitored and the treatment with fenofibrate stopped in the case of severe alteration oflaboratory parameters.
Glitazones
Some cases of reversible paradoxical reduction of HDL-cholesterol have been reported duringconcomitant administration of fenofibrate and glitazones. Therefore, it is recommended to monitor
HDL-cholesterol if Pravafenix is co-administered with a glitazone and to stop one of the twotreatments if HDL-cholesterol is too low.
Food interactionPravafenix must be taken with food, as food enhances the bioavailability of fenofibrate (see sections4.2 and 5.2).
In all clinical trials, patients were instructed to take Pravafenix daily during the evening meal anddietary restrictions instituted before therapy should be continued. Since current safety and efficacydata are based upon administration with food and with dietary restrictions, it is recommended that
Pravafenix is administered with food. (see sections 4.2 and 5.2).
4.6 Fertility, pregnancy and lactation
PregnancyPravafenix
There are no data from the combined use of pravastatin and fenofibrate in pregnant women. Thecombination has not been tested in reproductive toxicity studies. The potential risk for humans isunknown. Therefore, as far as pravastatin is contra indicated (see below), Pravafenix is contraindicatedduring pregnancy (see section 4.3).
Pravastatin sodium
Pravastatin is contraindicated during pregnancy and should be administered to women of childbearingpotential only when such patients are unlikely to conceive and have been informed of the potentialrisk. Special caution is recommended in women of childbearing potential to ensure properunderstanding of the potential risk associated with pravastatin therapy during pregnancy. If a patientplans to become pregnant or becomes pregnant, the physician has to be informed immediately andpravastatin should be discontinued because of the potential risk to the foetus.
Fenofibrate
There are no data from the use of fenofibrate in pregnant women. Animal studies have notdemonstrated any teratogenic effects. Embryotoxic effects have been shown at doses in the range ofmaternal toxicity (see section 5.3). The potential risk for humans is unknown.
BreastfeedingPravafenix
No studies in lactating animals have been conducted with Pravafenix. Therefore, taking into accountthe contra indication of pravastatin during lactation, Pravafenix is contraindicated during breastfeeding(see section 4.3).
Pravastatin sodium
A small amount of pravastatin is excreted in human breast milk; therefore pravastatin iscontraindicated during breastfeeding (see section 4.3).
Fenofibrate
Fenofibrate is excreted in milk of female rat.
There are no data on the excretion of fenofibrate and/or its metabolites into human breast milk.
FertilityNo effect on fertility in reproductive toxicity studies have been observed with both fenofibrate andpravastatin (see section 5.3)
There are no data on fertility from the combined use of fenofibrate and pravastatin
4.7 Effects on ability to drive and use machines
Pravafenix has no or negligible influence on the ability to drive and use machines. However, whendriving vehicles or using machines, it should be taken into account that dizziness and visualdisturbances may occur during treatment.

5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Lipid modifying agents, HMG CoA reductase inhibitors in combinationwith other lipid modifying agents, ATC code: C10BA03
Pharmacodynamic effectsPravafenix contains fenofibrate and pravastatin, which have different modes of action and showadditive effects in terms of reduction of serum lipid. The following statements reflect thepharmacodynamic/pharmacokinetic properties of the individual active substances of Pravafenix.
Fenofibrate
Fenofibrate is a fibric acid derivative whose lipid modifying effects reported in humans are mediatedvia activation of Peroxisome Proliferator Activated Receptor type alpha (PPARα). Studies withfenofibrate on lipoprotein fractions show decreases in levels of LDL and VLDL cholesterol. HDLcholesterol levels are frequently increased. LDL and VLDL triglycerides are reduced. The overalleffect is a decrease in the ratio of low and very low-density lipoproteins to high-density lipoproteins.
The lipid-lowering properties of fenofibrate seen in clinical practice have been explained in vivo intransgenic mice and in human hepatocyte cultures by activation of Peroxisome Proliferator Activated
Receptor type α (PPARα). Through this mechanism, fenofibrate increases lipolysis and elimination oftriglyceride rich particles from plasma by activating lipoprotein lipase and reducing production of
Apoprotein C-III. Activation of PPARα also induces an increase in the synthesis of Apoproteins A-I,
A-II and of HDL cholesterol.
There is evidence that treatment with fibrates may reduce coronary heart disease events but they havenot been shown to decrease all cause mortality in the primary or secondary prevention ofcardiovascular disease.
The Action to Control Cardiovascular Risk in Diabetes (ACCORD) lipid trial was a randomizedplacebo-controlled study of 5,518 patients with type 2 diabetes mellitus treated with fenofibrate inaddition to simvastatin. Fenofibrate plus simvastatin therapy did not show any significant differencescompared to simvastatin monotherapy in the composite primary outcome of non-fatal myocardialinfarction, non-fatal stroke, and cardiovascular death (hazard ratio [HR] 0.92, 95% CI 0.79-1.08, p =0.32 ; absolute risk reduction: 0.74%). In the pre-specified subgroup of dyslipidaemic patients, definedas those in the lowest tertile of HDL-C (≤34 mg/dl or 0.88 mmol/L) and highest tertile of TG (≥204mg/dl or 2.3 mmol/L) at baseline, fenofibrate plus simvastatin therapy demonstrated a 31% relativereduction compared to simvastatin monotherapy for the composite primary outcome (hazard ratio[HR] 0.69, 95% CI 0.49-0.97, p = 0.03 ; absolute risk reduction: 4.95%). Another prespecifiedsubgroup analysis identified a statistically significant treatment-by-gender interaction (p = 0.01)indicating a possible treatment benefit of combination therapy in men (p=0.037) but a potentiallyhigher risk for the primary outcome in women treated with combination therapy compared tosimvastatin monotherapy (p=0.069). This was not observed in the aforementioned subgroup of patientswith dyslipidaemia but there was also no clear evidence of benefit in dyslipidaemic women treatedwith fenofibrate plus simvastatin, and a possible harmful effect in this subgroup could not beexcluded.
Plasma uric acid levels are increased in approximately 20% of hyperlipidaemic patients, particularly inthose with type IV disease. Fenofibrate has a uricosuric effect and is therefore of additional benefit insuch patients.
Pravastatin
Pravastatin is a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA)reductase, the enzyme catalysing the early rate-limiting step in cholesterol biosynthesis, and producesits lipid-lowering effect in two ways. Firstly, with the reversible and specific competitive inhibition of
HMG-CoA reductase, it effects modest reduction in the synthesis of intracellular cholesterol. Thisresults in an increase in the number of LDL-receptors on cell surfaces and enhanced receptor-mediatedcatabolism and clearance of circulating LDL-cholesterol.
Secondly, pravastatin inhibits LDL production by inhibiting the hepatic synthesis of VLDL-cholesterol, the LDL-cholesterol precursor.
In both healthy subjects and patients with hypercholesterolaemia, pravastatin lowers the followinglipid values: total cholesterol, LDL-cholesterol, apolipoprotein B, VLDL-cholesterol and triglycerides;while HDL-cholesterol and apolipoprotein A are elevated.
Pravafenix
The respective effects of pravastatin and fenofibrate are complementary. Pravastatin is more effectivein reducing LDL-C and total cholesterol but presents only modest effects on TG and HDL-C whilefenofibrate is very effective in decreasing TG and increasing HDL-C, but with few effects on LDL-C.
Additionally, fibrates have the properties to modify the size and density of LDL-C particles to makethem less atherogenic.
Fibrates and statins in combination have also been shown to synergistically increase the transcriptionalactivities of PPARα receptors.
Clinical efficacy and safetyFour multicenter studies with either Pravafenix 40 mg/160 mg or Pravastatin 40 mg or Simvastatin20 mg were conducted: 3 studies included a 12 week randomized, double-blind, active controlledperiod with an open-label extension phase and one was a 24-week open-label study.
In total, these studies enrolled 1,637 patients who have not had an adequate response to treatment withpravastatin 40 mg monotherapy or simvastatin 20 mg in Europe and in the USA.
In the pivotal European multicenter 64-week clinical trial including 12 week randomised, double-blind, double-dummy, 2-arm, parallel study period, 248 high vascular risk patients with mixeddyslipidaemia were randomised to one of the two treatment groups: Pravafenix 40 mg/160 mg orpravastatin 40 mg. Only patients who had not met their NCEP ATP III target LDL-C and Triglyceridegoals (LDL >100 mg/dl and TG >150 mg/dl) after 8 weeks on pravastatin 40 mg (1 tablet, once daily)were randomized. Patients receiving Pravafenix 40 mg/160 mg were compared to those receivingpravastatin 40 mg: Pravafenix significantly lowered non-HDL-C, LDL-C, TG and significantlyincreased HDL-C to a greater extent than pravastatin 40 mg (table).

The effects of Pravafenix 40 mg/160 mg were confirmed in a similar multicenter, 64-week trialincluding a 12 week randomized, double-blind phase in a study performed in the USA and comparing
Pravafenix 40 mg/160 mg to Fenofibrate 160 mg monotherapy and Pravastatin 40 mg monotherapy inpatients with mixed dyslipidaemia. The incremental benefit of Pravafenix 40 mg/160 mg on main lipidparameters versus Pravastatin 40 mg and Fenofibrate 160 mg monotherapy was also established.
Paediatric populationThe European Medicines Agency has waived the obligation to submit the results of studies with
Pravafenix in all subsets of the paediatric population in disorders of lipoprotein metabolism and otherhyperlipidaemias (see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
No clinically significant pharmacokinetic interaction was seen when fenofibrate was coadministeredwith pravastatin.
AbsorptionPravafenix is bioequivalent to coadministered fenofibrate and pravastatin in a single dose study.
However in a multiple dose study, the results showed that the product is not bioequivalent because itsbioavailability after multiple dosing is a 20% lower for the fenofibrate component of the combination.
This is due to the fat content of the meal.
Therefore the fixed dose combination (Pravafenix) could not be considered interchangeable with thefree co-administration of fenofibrate and pravastatin mono-component drug products.
A pharmacokinetic study after a single dose administration of Pravafenix has been performed in fedand fasting condition. The results of this study show that food has effect on the rate and extent ofabsorption in the fixed dose combination. The bioavailability of fenofibric acid is lower in fastingconditions after a single dose administration of the Fenofibrate-Pravastatin 160/40 mg combination.
The decreased in AUCt, AUC∞ and Cmax of fenofibric acid (point estimate) is of 30.94%, 10.9% and68.71% respectively.
The bioavailability of pravastatin is higher after a single dose administration of the test product
Fenofibrate/Pravastatin 160/40 mg in fasting conditions than after a single dose of the product in fedconditions. The increase in AUC∞, AUCt, and Cmax is of 111.88%, 114.06%, and 115.28%respectively. In line with several formulations for fenofibrate, the fixed combination is recommendedto be taken with food because the bioavailability of fenofibrate is increased when administered withfood and the lipid-lowering efficacy of pravastatin is not altered.
Pravastatin
Pravastatin is administered orally in the active form. It is rapidly absorbed; peak serum levels areachieved 1 to 1.5 hours after ingestion. On average, 34% of the orally administered dose is absorbed,with an absolute bioavailability of 17%.
The presence of food in the gastrointestinal tract leads to a reduction in the bioavailability, but thecholesterol-lowering effect of pravastatin is identical whether taken with or without food.
After absorption, 66% of pravastatin undergoes a first-pass extraction through the liver, which is theprimary site of its action and the primary site of cholesterol synthesis and clearance of LDL-cholesterol. In vitro studies demonstrated that pravastatin is transported into hepatocytes and withsubstantially less intake in other cells. In view of this substantial first pass through the liver, plasmaconcentrations of pravastatin have only a limited value in predicting the lipid-lowering effect.
The plasma concentrations are proportional to the doses administered.
Fenofibrate
Maximum plasma concentrations (Cmax) occur within 4 to 5 hours after oral administration. Plasmaconcentrations are stable during continuous treatment in any given individual.
The absorption of fenofibrate is increased when administered with food. The food effect increases withthe fat content: the larger the lipid content the larger the bioavailability of fenofibrate.
DistributionPravastatin
About 50% of circulating pravastatin is bound to plasma proteins. The volume of distribution is about0.5 l/kg. A small quantity of pravastatin passes into the human breast milk.
Fenofibrate
Fenofibric acid is strongly bound to plasma albumin (more than 99%).
Biotransformation and eliminationPravastatin
Pravastatin is not significantly metabolised by cytochrome P450 nor does it appear to be a substrate oran inhibitor of P-glycoprotein but rather a substrate of other transport proteins.
Following oral administration, 20% of the initial dose is eliminated in the urine and 70% in the faeces.
Plasma elimination half-life of oral pravastatin is 1.5 to 2 hours.
After intravenous administration, 47% of the dose is eliminated by the renal excretion and 53% bybiliary excretion and biotransformation. The major degradation product of pravastatin is the 3-α-hydroxy isomeric metabolite. This metabolite has one-tenth to one-fortieth the HMG-CoA reductaseinhibitor activity of the parent compound.
The systemic clearance of pravastatin is 0.81 l/h/kg and the renal clearance is 0.38 l/h/kg indicatingtubular secretion.
Fenofibrate
No unchanged fenofibrate can be detected in the plasma where the principal metabolite is fenofibricacid. The drug is excreted mainly in the urine. Practically all the drug is eliminated within 6 days.
Fenofibrate is mainly excreted in the form of fenofibric acid and its glucuronide conjugate. In elderlypatients, the fenofibric acid apparent total plasma clearance is not modified. The plasma eliminationhalf-life of fenofibric acid is approximately 20 hours.
Kinetic studies following the administration of a single dose and continuous treatment havedemonstrated that the drug does not accumulate. Fenofibric acid is not eliminated by haemodialysis.
5.3 Preclinical safety data
The safety of concomitant administration of pravastatin and fenofibrate was assessed in rats.
Toxicological findings in these co-administration studies were consistent with those seen withpravastatin and fenofibrate administered individually.
Pravastatin
Based on conventional studies of safety pharmacology, repeated dose toxicity and toxicity onreproduction, there are no other risks for the patient than those expected due to the pharmacologicalmechanism of action.
Repeated dose studies indicate that pravastatin may induce varying degrees of hepatotoxicity andmyopathy; in general, substantive effects on these tissues were only evident at doses 50 or more timesthe maximum human mg/kg dose. In vitro and in vivo genetic toxicology studies have shown noevidence of mutagenic potential. In mice, a 2-year carcinogenicity study with pravastatin demonstratesat doses of 250 and 500 mg/kg/day (> 310 times the maximum human mg/kg dose), statisticallysignificant increases in the incidence of hepatocellular carcinomas in males and females, and lungadenomas in females only. In rats a 2-year carcinogenicity study demonstrates at a dose of100 mg/kg/day (125 times the maximum human mg/kg/dose) a statistically significant increase in theincidence of hepatocellular carcinomas in males only.
Fenofibrate
Chronic toxicity studies have yielded no relevant information about specific toxicity of fenofibrate.
Studies on mutagenicity of fenofibrate have been negative. In rats and mice, liver tumours have beenfound at high dosages, which are attributable to peroxisome proliferation. These changes are specificto small rodents and have not been observed in other animal species. This is of no relevance totherapeutic use in man.
Studies in mice, rats and rabbits did not reveal any teratogenic effect. Embryotoxic effects wereobserved at doses in the range of maternal toxicity. Prolongation of the gestation period anddifficulties during delivery were observed at high doses. No sign of any effect on fertility has beendetected.
