Drug information of Nimodipine


Drug group:

Nimodipine is a calcium channel blocker. Nimodipine relaxes (widens) blood vessels and improves blood flow. Nimodipine is used to prevent brain damage caused by reduced blood flow to the brain resulting from aneurysm (AN-yor-iz-m), a dilated or ruptured blood vessel in the brain.

Mechanism of effect

Nimodipine is a calcium channel blocker. The contractile processes of smooth muscle cells are dependent upon calcium ions, which enter these cells during depolarization as slow ionic transmembrane currents. Nimodipine inhibits calcium ion transfer into these cells and thus inhibits contractions of vascular smooth muscle.


Nimodipine belongs to the class of pharmacological agents known as calcium channel blockers.


Nimodipine is rapidly absorbed after oral administration, and peak concentrations are generally attained within one hour. The terminal elimination half-life is approximately 8 to 9 hours. Nimodipine is over 95% bound to plasma proteins. Nimodipine is eliminated almost exclusively in the form of metabolites and less than 1% is recovered in the urine as unchanged drug


Usual Adult Dose for Subarachnoid Hemorrhage 60 mg orally every 4 hours Therapy should be started within 96 hours of the event and continued for 21 days.


1- Do not administer nimodipine intravenously or by other parenteral routes. Deaths and serious, life threatening adverse events, including cardiac arrest, cardiovascular collapse, hypotension, and bradycardia, have occurred when the contents of nimodipine capsules have been injected parenterally 2- Blood pressure should be monitored carefully during nimodipine therapy. 3- The metabolism of Nimodipine capsules is decreased in patients with impaired hepatic function. Such patients should have their blood pressure and pulse rate monitored closely and should be given a lower dose 4- Safety and effectiveness have not been established in pediatric patients (less than 18 years of age).

Points of recommendation

1-Tell your doctor or dentist that you take nimodipine before you receive any medical or dental care, emergency care, or surgery. 2-Nimodipine may cause dizziness or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use nimodipine with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it. 3-Your blood pressure and heart rate will need to be monitored while you use nimodipine.
