Aclidinium bromide is an inhaled bronchodilator used as maintenance treatment in adults with chronic obstructive pulmonary disease. It belongs to the long-acting muscarinic antagonist class and relaxes airway smooth muscle, helping reduce breathlessness and improve daily breathing.
It is administered through an inhaler according to the prescribed schedule, usually twice daily. It is not a rescue medicine and should not be used for sudden attacks of breathlessness; a prescribed fast-acting bronchodilator should be used for that. Correct inhaler technique is essential, and the patient should know how to load, inhale and check the dose.
Side effects may include headache, nasopharyngitis, cough, sinusitis, dry mouth, nausea or throat irritation. Because it has anticholinergic effects, it may rarely worsen narrow-angle glaucoma or urinary retention, especially in patients with enlarged prostate. Inhalation can rarely cause paradoxical bronchospasm, with immediate worsening of breathing.
Contact a doctor urgently if severe wheezing occurs immediately after inhalation, eye pain, blurred vision, coloured halos, difficulty urinating, chest pain or allergic reactions appear. Tell the doctor about glaucoma, prostate problems, urinary retention and all inhalers used. Treatment works best when used regularly.
