Pharmacology
Indication: For use as an adjunct to improve neurologic outcome following subarachnoid hemorrhage (SAH) from ruptured intracranial berry aneurysms by reducing the incidence and severity of ischemic deficits.
Pharmacology:
Nimodipine belongs to the class of pharmacological agents known as calcium channel blockers. Nimodipine is indicated for the improvement of neurological outcome by reducing the incidence and severity of ischemic deficits in patients with subarachnoid hemorrhage from ruptured congenital aneurysms who are in good neurological condition post-ictus (e....

Mechanism of Action:
Although the precise mechanism of action is not known, nimodipine blocks intracellular influx of calcium through voltage-dependent and receptor-operated slow calcium channels across the membranes of myocardial, vascular smooth muscle, and neuronal cells. Nimodipine binds specifically to L-type voltage-gated calcium channels. The inhibition of calci...

Absorption: Bioavailability is 100% following intravenous administration and 3-30% following oral administration due to extensive first-pass metabolism.
Protein binding: 95%
Biotransformation: Hepatic metabolism via cytochrome P450 3A4.
Half Life: 1.7-9 hours
Toxicity: Symptoms of overdosage would be expected to be related to cardiovascular effects such as excessive peripheral vasodilation with marked systemic hypotension.
Affected organisms: Humans and other mammals
Interactions
Food interaction:
Take at the same time each day, with or without food, but always in the same manner.
Grapefruit down regulates post-translational expression of CYP3A4, the major metabolizing enzyme of nimodipine. Grapefruit, in all forms (e.g. whole fruit, juice and rind), can significantly increase serum levels of nimodipine and may cause toxicity. Avoid grapefruit products while on this medication.
Drug interaction:
Valproic AcidValproic acid increases the effect of nimodipine
Divalproex sodiumValproic acid increases the effect of nimodipine
TipranavirTipranavir may decrease the metabolism and clearance of the calcium channel blocker, Nimodipine. Monitor for changes in Nimodipine therapeutic and adverse effects if Tipranavir is initiated, discontinued or dose changed.
TelithromycinTelithromycin may reduce clearance of Nimodipine. Consider alternate therapy or monitor for changes in the therapeutic/adverse effects of Nimodipine if Telithromycin is initiated, discontinued or dose changed.
CimetidineCimetidine increases the effect of the calcium channel blocker, nimodipine.
