Flunarten-P Tablet SR is a combination medication containing Propranolol 40mg and Flunarizine 10mg, designed to provide sustained relief from conditions such as migraine prophylaxis, hypertension, and certain neurological disorders. Propranolol, a non-selective beta-blocker, works by blocking beta-adrenergic receptors, thereby reducing heart rate, blood pressure, and the workload on the heart, which helps in managing hypertension and preventing migraine attacks. Flunarizine, a calcium channel blocker with antihistaminic properties, helps prevent migraine by inhibiting the excessive influx of calcium ions into the brain cells, stabilizing neuronal activity, and reducing vasospasm. The sustained-release formulation ensures a gradual release of the active ingredients, maintaining consistent therapeutic levels in the bloodstream, enhancing efficacy, and improving patient compliance by reducing dosing frequency. Flunarten-P is typically prescribed for patients who require both cardiovascular and neurological symptom management, particularly those suffering from migraine with or without aura, and those with coexisting hypertension or anxiety-related tachycardia. It should be used under medical supervision, with caution in patients with asthma, bradycardia, or severe liver impairment. Common side effects may include fatigue, dizziness, gastrointestinal discomfort, and cold extremities. Regular monitoring and adherence to prescribed dosage are essential for optimal outcomes.
