🌿 What is Nimodipine 30 mg (Nimodip)?

Nimodip is a dihydropyridine calcium channel blocker with high lipophilicity, allowing selective cerebral vessel penetration. It is used primarily to prevent and reduce the severity of cerebral vasospasm following subarachnoid hemorrhage (SAH). By inhibiting calcium influx in vascular smooth muscle, Nimodipine promotes vasodilation and improves cerebral blood flow.

Clinical studies demonstrate that Nimodipine 30 mg administered every 4 hours for 21 days reduces neurological deficits and mortality in SAH patients. Early initiation within 96 hours of hemorrhage onset maximizes benefit.

For detailed prescribing and safety information, consult the FDA label for Nimotop and the Drugs.com monograph. Additional guidance is available via the NHS Medicines A–Z entry and the WHO Essential Medicines List.

🧬 Pharmacology & Mechanism of Action

Attribute	Detail
Chemical Formula	C21H26N2O7
Molecular Weight	418.44 g/mol
Bioavailability	~13% (due to first-pass metabolism)
Metabolism	Hepatic (CYP3A4)
Half-Life	~8–9 hours

Nimodipine’s cerebral selectivity arises from its high lipid solubility and preferential binding to cerebral arteries.

💡 Indications & Dosing

Condition	Dose & Administration
Subarachnoid Hemorrhage (SAH)	30 mg orally every 4 hours for 21 days; start within 96 hours of hemorrhage

Administer on an empty stomach for optimal absorption; avoid concomitant grapefruit products.
