A03DA02 • metamizole sodium + pitofenone hydrochloride + fenpiverinium bromide • Alimentary tract and metabolism | Antispasmodics in combination with analgesics | Synthetic anticholinergic agents in combination with analgesics

This combination of metamizole sodium, pitofenone hydrochloride, and fenpiverinium bromide is used to relieve acute moderate to severe pain, especially spasmodic pain such as renal, biliary, or intestinal colic. It has analgesic, antispasmodic, and anti-inflammatory properties.

Metamizole sodium is an analgesic and antipyretic that reduces pain and fever. Pitofenone hydrochloride has a direct muscle-relaxing effect on smooth muscles, reducing spasms. Fenpiverinium bromide, an anticholinergic, enhances the antispasmodic effect by reducing involuntary muscle contractions.

This combination is effective in treating pain associated with spasms of internal organs, such as the gastrointestinal or urinary tract. It can also be used to relieve severe menstrual pain or other conditions involving muscle spasms.

Side effects may include dry mouth, dizziness, nausea, constipation, or allergic reactions. In rare cases, severe reactions such as low blood pressure, breathing difficulties, or serious skin reactions may occur. Patients should inform their doctor about any side effects or other medications they are taking.

Patients must strictly follow the dosage recommended by their doctor, as excessive use can lead to serious adverse effects. It is also contraindicated in certain conditions, such as severe renal or hepatic insufficiency or allergies to any of the components.
