nicardipine hydrochloride: clinical details
Prescribing considerations
- Use only under specialist supervision in a controlled hospital environment.
- Avoid abrupt or excessive blood-pressure reduction; account for possible reflex tachycardia.
- Use particular caution in older people and in renal or hepatic impairment, heart failure, pulmonary oedema, coronary ischaemia, acute cerebral infarction or raised intracranial pressure.
- Assess the infusion site regularly.
- The formulation contains sorbitol; hereditary fructose intolerance requires specific assessment.
Contraindications and cautions
- Hypersensitivity to nicardipine or an excipient
- Severe aortic stenosis
- Compensatory hypertension associated with an arteriovenous shunt or aortic coarctation
- Unstable angina
- Myocardial infarction within the preceding eight days
Monitoring
- Continuous blood-pressure and heart-rate monitoring during infusion
- Vital signs after stopping until stable
- Infusion-site condition
- Cardiac failure and pulmonary-oedema features
- Renal and hepatic function where clinically relevant
- Intracranial and cerebral perfusion pressures in patients at risk
- Digoxin or immunosuppressant concentrations when interacting treatment is present
Clinical pharmacology
A vascular-selective dihydropyridine that inhibits L-type calcium influx mainly in arterial smooth muscle. It lowers peripheral vascular resistance and is highly protein-bound and extensively metabolised through CYP3A4.
Formulation and product differences
- The selected product is a clear, pale-yellow solution in a brown-glass ampoule for continuous intravenous infusion.
- It should not be administered as an uncontrolled intravenous bolus.
- Peripheral administration requires appropriate dilution; compatibility and adsorption risks must be checked before mixing or selecting infusion equipment.
- The solution contains sorbitol, very little sodium and should be protected from light.
nicardipine hydrochloride preparations and strengths
Injection
Route: Parenteral

nicardipine hydrochloride interactions
Important interactions include:
Beta-blockers
May increase the risk of low blood pressure or worsening heart failure, particularly when cardiac function is reduced.
Magnesium sulphate
May increase the risk of excessive blood-pressure reduction or pulmonary oedema.
Strong CYP3A4 inhibitors
Clarithromycin, ritonavir and azole antifungals may increase nicardipine exposure and adverse effects.
CYP3A4 inducers
Carbamazepine, phenytoin, phenobarbital and rifampicin may reduce nicardipine exposure.
