Indication and Use
NYMALIZE is indicated for the improvement of neurological outcome by reducing the incidence and severity of ischemic deficits in adult patients with subarachnoid hemorrhage (SAH) from ruptured intracranial berry aneurysms regardless of their post-ictus neurological condition (i.e., Hunt and Hess Grades I—V).
Important Safety Information
Blood pressure should be carefully monitored during treatment with Nymalize. Nimodipine may increase the blood pressure-lowering-effect of concomitantly administered anti-hypertensives such as diuretics, beta-blockers, ACE inhibitors, angiotensin receptor blockers, other calcium channel blockers, α-adrenergic blockers, PDE5 inhibitors, and α-methyldopa.
Patients with cirrhosis are at a higher risk of adverse reactions and should be monitored closely and administered a lower dose.
Concomitant use of strong inhibitors of CYP3A4 with nimodipine should generally be avoided because of risk of significant hypotension. These include some macrolide antibiotics (eg, clarithromycin, telithromycin), some HIV protease inhibitors (eg, indinavir, nelfinavir, ritonavir, saquinavir), some HCV protease inhibitors (eg, boceprevir, telaprevir), some azole antimycotics (eg, ketoconazole, itraconazole, posaconazole, voriconazole), conivaptan, delavirdine, and nefazodone.
Concomitant use of strong CYP3A4 inducers (eg, carbamazepine, phenobarbital, phenytoin, rifampin, St John's wort) and nimodipine should generally be avoided, as nimodipine plasma concentration and efficacy may be significantly reduced.
Nimodipine plasma concentration can also be increased in the presence of moderate and weak inhibitors of CYP3A4. If nimodipine is concomitantly administered with these drugs, blood pressure should be monitored, and a reduction of the nimodipine dose may be necessary.
Grapefruit juice inhibits CYP3A4. Ingestion of grapefruit/grapefruit juice is not recommended while taking nimodipine.
Moderate and weak inducers of CYP3A4 may also reduce the efficacy of nimodipine. Patients on these should be closely monitored for lack of effectiveness, and a nimodipine dosage increase may be required.
Common Adverse Reactions
Most common adverse reactions (incidence ≥1% and ≥1% placebo) were hypotension, headache, nausea, and bradycardia.
