Information sourced from FDA Structured Product Labeling, updated August 30, 2024.

What is it used for?

1 INDICATIONS AND USAGE 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). NYMALIZE is a dihydropyridine calcium channel blocker 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).

How to take it

Administer only enterally (e.g., oral, nasogastric tube, or gastric tube route). Do not administer intravenously or by other parenteral routes. Give one hour before a meal or two hours after a meal. Start dosing within 96 hours of the SAH. Recommended dose is 10 mL (60 mg) every 4 hours for 21 consecutive days. Nasogastric or Gastric Tube Administration: Administer 10 mL (60 mg) every 4 hours with supplied prefilled oral syringe. Refill syringe with 10 mL of 0.9% saline water solution; flush remaining contents from nasogastric or gastric tube into stomach. Patients with Cirrhosis: Reduce dosage to 5 mL (30 mg) every 4 hours.

Administration Instructions Administer

only enterally (e.g., oral, nasogastric tube, or gastric tube route). Do not administer intravenously or by other parenteral routes. For all routes of administration, begin NYMALIZE within 96 hours of the onset of SAH. Administer one hour before a meal or two hours after a meal for all routes of administration .

Administration by Oral Route The

recommended oral dosage is 10 mL (60 mg) every 4 hours for 21 consecutive days.

Administration Via Nasogastric or Gastric Tube

Using the supplied prefilled oral syringe labeled "For Oral Use Only", administer 10 mL (60 mg) every 4 hours into a nasogastric or gastric tube for 21 consecutive days. For each dose, refill the syringe with 10 mL of 0.9% saline solution and then flush any remaining contents from nasogastric or gastric tube into the stomach.

Dosage Adjustments in Patients with Cirrhosis In

patients with cirrhosis, reduce the dosage to 5 mL (30 mg) every 4 hours [ s ee Warnings and Precautions , Clinical Pharmacology ] .

Warnings

Hypotension: Monitor blood pressure. Patients with Cirrhosis: Higher risk of adverse reactions. Monitor blood pressure and pulse. CYP3A4 Strong Inhibitors: May significantly increase risk of hypotension. Concomitant use with NYMALIZE should generally be avoided. CYP3A4 Strong Inducers: May significantly reduce efficacy of nimodipine. Concomitant use with NYMALIZE should generally be avoided.

Hypotension Blood

pressure should be carefully monitored during treatment with NYMALIZE. In clinical studies of patients with subarachnoid hemorrhage, about 5% of nimodipine-treated patients compared to 1% of placebo-treated patients had hypotension and about 1% of nimodipine-treated patients left the study because of this .

Possible Increased Risk of Adverse Reactions

in Patients with Cirrhosis Given that the plasma levels of nimodipine are increased in patients with cirrhosis, these patients are at higher risk of adverse reactions. Therefore, monitor blood pressure and pulse rate closely and administer a lower dosage .

Possible Increased Risk of Hypotension with Strong

CYP3A4 Inhibitors Concomitant use of strong inhibitors of CYP3A4, such as some macrolide antibiotics (e.g., clarithromycin, telithromycin), some HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, saquinavir), some HCV protease inhibitors (e.g., boceprevir, telaprevir), some azole antimycotics (e.g., ketoconazole, itraconazole, posaconazole, voriconazole), conivaptan, delavirdine, and nefazodone with nimodipine should generally be avoided because of a risk of significant hypotension .

Possible Reduced Efficacy with Strong CYP3A4

Inducers Concomitant use of strong CYP3A4 inducers (e.g., carbamazepine, phenobarbital, phenytoin, rifampin, St. John's wort) and nimodipine should generally be avoided, as nimodipine plasma concentration and efficacy may be significantly reduced .

Who should not take it

None. None

Pregnancy

Pregnancy Risk Summary There

are no adequate data on the developmental risk associated with the use of NYMALIZE in pregnant women. In animal studies, oral administration of nimodipine during pregnancy resulted in adverse effects on development (increased embryofetal mortality, increased incidences of fetal structural abnormalities, decreased fetal growth) at doses equivalent to (rat) or less than (rabbit) those used clinically . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.

Data Animal Data Nimodipine has been shown to have a teratogenic effect in two studies in rabbit. In one study, incidences of malformations and stunted fetuses were increased at oral doses of 1 mg/kg/day and 10 mg/kg/day administered throughout organogenesis but not at 3 mg/kg/day. In the second study, an increased incidence of stunted fetuses was seen at 1 mg/kg/day but not at higher doses (3 mg/kg/day and 10 mg/kg/day).

The lowest effect dose in rabbits (1 mg/kg/day) is less than the recommended human dose (RHD) of 360 mg/day on a body surface area (mg/m 2 ) basis. Nimodipine was embryotoxic, causing resorption and stunted growth of fetuses in rats at 100 mg/kg/day administered orally throughout organogenesis; this dose is approximately 3 times the RHD on a mg/m 2 basis. In two other studies in rats, nimodipine administered orally at 30 mg/kg/day throughout organogenesis and continued until sacrifice (day 20 of pregnancy or day 21 postpartum) was associated with higher incidences of skeletal variation, stunted fetuses, and stillbirths but no malformations; this dose is similar to the RHD on a mg/m 2 basis.

Side effects

The safety and efficacy of NYMALIZE (nimodipine oral solution) in the treatment of patients with SAH is based on adequate and well-controlled studies of nimodipine oral capsules in patients with SAH. NYMALIZE (nimodipine oral solution) has comparable bioavailability to nimodipine oral capsules. The following clinically significant adverse reaction appears in other sections of the labeling: Hypotension . Most common adverse reactions (incidence ≥1% and ≥1% placebo) were hypotension, headache, nausea, and bradycardia.

Clinical Trials Experience Because

clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. In clinical trials of nimodipine oral capsules in patients with SAH, eleven percent (92 of 823) of nimodipine-treated patients reported adverse events compared to six percent (29 of 479) of placebo-treated patients. The most common adverse event was decreased blood pressure in 4.4% of nimodipine-treated patients.

The events reported with a frequency greater than 1% are displayed in Table 1 by dose. Table 1: Adverse Events [n (%)] reported with a frequency > 1% in four clinical trials (Study 1, Study 2, Study 3, and Study 4) Placebo (n=479) Nimodipine dose every 4 hours 0.35 mg/kg (n=82) 30 mg (n=71) 60 mg (n=494) 90 mg (n=172) 120 mg (n=4) Decreased Blood Pressure 6 1 0 19 14 2 Edema 3 0 0 2 2 0 Diarrhea 3 0 3 0 3 0 Rash 3 2 0 3 2 0 Headache 1 0 1 6 0 0 Gastrointestinal Symptoms 0 2 0 0 2 0 Nausea 0 1 1 6 1 0 Dyspnea 0 1 0 0 0 0 EKG Abnormalities 0 0 1 0 1 0 Tachycardia 0 0 1 0 0 0 Bradycardia 0 0 0 5 1 0 Muscle Pain/Cramp 0 0 1 1 1 0 Acne 0 0 1 0 0 0 Depression 0 0 1 0 0 0 SAH is frequently accompanied by alterations in consciousness that may lead to an under-reporting of adverse experiences. As a calcium channel blocker, nimodipine may have the potential to exacerbate heart failure in susceptible patients or to interfere with A-V conduction, but these events were not observed in SAH trials.
