Manidón

Verapamil, the active ingredient in Manidón, is a calcium channel blocker presented as a tablet (strength not specified) for oral use. It treats hypertension, angina pectoris and certain supraventricular tachyarrhythmias in adult patients.

GNH USA supplies Manidón as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Verapamil is a calcium channel blocker used in cardiovascular conditions.

Hypertension: lowers blood pressure by reducing peripheral vascular resistance. Angina pectoris: relieves chest pain by decreasing myocardial oxygen demand. Supraventricular tachyarrhythmias: controls heart rate by slowing conduction through the atrioventricular node.

Common side effects are generally mild and may resolve with continued therapy.

Common Side Effects: - Headache: mild to moderate head pain. - Dizziness: sensation of light‑headedness. - Constipation: reduced bowel motility. - Peripheral edema: swelling of the ankles or lower legs.

Serious or Rare Side Effects: - Severe hypotension: marked drop in blood pressure. - Bradycardia: abnormally slow heart rate. - Atrioventricular block: impaired electrical conduction between atria and ventricles.

Before initiating verapamil therapy, consider the following precautions.

Cardiovascular assessment: evaluate blood pressure and heart rate prior to treatment. Concomitant beta‑blockers: monitor for excessive bradycardia. Liver impairment: use with caution; dose may need adjustment. Renal impairment: monitor drug levels in severe dysfunction. Pregnancy and lactation: avoid unless benefits outweigh risks. Store at ambient temperature: keep below 25°C in the original container, protect from moisture.

Verapamil may interact with several medicines; awareness of the interaction level is essential.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): can markedly increase verapamil plasma concentrations. - Digoxin: concurrent use may raise digoxin levels and risk toxicity.

Moderate Interactions (Monitor Closely): - Beta‑blockers: combined effect may cause excessive bradycardia or AV block. - Diuretics: may enhance hypotensive effect. - Antacids containing aluminum or magnesium: may reduce absorption of verapamil.
