Nicardipine Hydrochloride Injection is a calcium channel blocker indicated for the short-term treatment of hypertension in adults when oral therapy is not feasible. (1.1) 1.1 Hypertension Nicardipine Hydrochloride Injection is indicated in adults for the short-term treatment of hypertension when oral therapy is not feasible or not desirable. For prolonged control of blood pressure, transfer patients to oral medication as soon as their clinical condition permits [see Dosage and Administration (2.1)].

Do not use in patients with advanced aortic stenosis ( 4.1 ). 4.1 Advanced Aortic Stenosis Nicardipine hydrochloride injection is contraindicated in patients with advanced aortic stenosis because part of the effect of nicardipine hydrochloride injection is secondary to reduced afterload. Reduction of diastolic pressure in these patients may worsen rather than improve myocardial oxygen balance.

Closely monitor response in patients with angina, heart failure, impaired hepatic function, or renal impairment. ( 5.1, 5.2, 5.3, 5.4 ) To reduce the possibility of venous thrombosis, phlebitis, and vascular impairment, do not use small veins, such as those on the dorsum of the hand or wrist. Exercise extreme care to avoid intra-arterial administration or extravasation. ( 5.5 ) To minimize the risk of peripheral venous irritation, change the site of infusion of nicardipine hydrochloride injection every 12 hours. ( 5.5 ) 5.1 Exacerbation of Angina Increases in frequency, duration, or severity of angina have been seen in chronic therapy with oral nicardipine. Induction or exacerbation of angina has been seen in less than 1% of coronary artery disease patients treated with nicardipine hydrochloride injection. The mechanism of this effect has not been established. 5.2 Exacerbation of Heart Failure Titrate slowly when using nicardipine hydrochloride injection, particularly in combination with a beta-blocker, in patients with heart failure or significant left ventricular dysfunction because of possible negative inotropic effects. 5.3 Increased Effect with Impaired Hepatic Function Since nicardipine is metabolized in the liver, consider lower dosages and closely monitor responses in patients with impaired liver function or reduced hepatic blood flow. 5.4 Prolonged Effect with Impaired Renal Function When nicardipine hydrochloride injection was given to mild to moderate hypertensive …

8.1 Pregnancy Risk Summary Available data from published literature (clinical trials and case series) over decades of use of intravenous nicardipine during pregnancy have not identified a drug-associated risk of major birth defects or miscarriage. However, nicardipine is predominantly used in pregnancy after 20 gestational weeks. Use of nicardipine in women with preeclampsia or pre-term labor is associated with maternal and fetal/neonatal adverse events. Maternal adverse events included pulmonary edema, dyspnea, hypoxia, hypotension, reflex tachycardia, postpartum hemorrhage, tocolysis, headache, nausea, dizziness, flushing, and phlebitis at site of injection. Fetal/neonatal adverse events …
