Isoptin Rr Retard

Verapamil Hydrochloride, the active ingredient in Isoptin Rr Retard, is a calcium channel blocker presented as a prolonged‑release oral tablet for oral use. It is employed to lower high blood pressure, relieve chest pain from angina, and control certain cardiac rhythm disorders such as atrial fibrillation and supraventricular tachycardia in adult patients.

GNH USA supplies Isoptin Rr Retard as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies, transplant centres and clinics worldwide, providing reliable quality and regulatory compliance.

Verapamil is a calcium channel blocker used to manage cardiovascular conditions.

- Hypertension: reduces systemic blood pressure by vasodilation of arterial smooth muscle. - Angina pectoris: alleviates chest pain by improving myocardial oxygen supply through coronary vasodilation. - Atrial fibrillation: helps control ventricular rate by slowing atrioventricular nodal conduction. - Supraventricular tachycardia: terminates episodes by reducing AV nodal conduction.

Common Side Effects: - Constipation: reduced gastrointestinal motility. - Dizziness: transient orthostatic changes. - Headache: mild vascular headache. - Flushing: transient skin warmth.

Serious or Rare Side Effects: - Severe bradycardia: markedly slowed heart rate. - Heart block: impaired AV nodal transmission. - Hypotension: significant drop in blood pressure.

Before initiating therapy, consider the following precautions: - Monitor blood pressure: ensure adequate control and avoid excessive hypotension. - Assess cardiac function: evaluate for existing conduction disorders. - Review concomitant beta‑blocker use: risk of additive AV block. - Adjust dose in hepatic impairment: reduced metabolism may increase exposure. - Avoid abrupt discontinuation: taper to prevent rebound hypertension. - Store at room temperature: keep in the original pack, protect from moisture.

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

Major Interactions (Avoid): - Beta‑blockers: additive AV nodal depression. - Digoxin: increased serum digoxin concentrations. - Strong CYP3A4 inhibitors (e.g., ketoconazole): elevated verapamil levels.

Moderate Interactions (Monitor Closely): - Amiodarone: potential increase in verapamil exposure. - ACE inhibitors: enhanced hypotensive effect.
