NICARDIPINE Solution for injection Ref.[8184] Active ingredients: Nicardipine

Posology

Nicardipine should only be administered by specialists in well controlled environments, such as hospitals and intensive care units, with continuous monitoring of blood pressure. The speed of administration must be accurately controlled by the use of an electronic syringe driver or a volumetric pump. Blood pressure and heart rate must be monitored at least every 5 minutes during the infusion, and then until vital signs are stable, but at least for 12 hours after the end of the administration of nicardipine.

The antihypertensive effect will depend on the administered dose. The dosage regimen to achieve the desired blood pressure can vary depending on the targeted blood pressure, the response of the patient, and the age or status of the patient.

Unless given by a central venous line, dilute to a concentration of 0.1-0.2 mg/ml before use (see section 6.2 for details of compatible solutions)

Adults

Initial dose: Treatment should start with the continuous administration of nicardipine at a rate of 3-5 mg/h for 15 minutes. Rates can be increased by increments of 0.5 or 1 mg every 15 minutes. The infusion rate should not exceed 15 mg/h.

Maintenance dose: When the target pressure is reached, the dose should be reduced progressively, usually to between 2 and 4 mg/h, to maintain the therapeutic efficacy.

Transition to an oral antihypertensive agent: discontinue nicardipine or titrate downward while appropriate oral therapy is established. When an oral antihypertensive agent is being instituted, consider the lag time of onset of the oral agent’s affect. Continue blood pressure monitoring until desired effect is achieved.

A switch can also be made to oral nicardipine 20mg capsules at dosage of 60 mg/day in 3 daily doses, or to nicardipine 50 mg extended-release tablets, at dosage of 100mg/day, in 2 daily doses.

Elderly

Clinical studies of nicardipine did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Elderly patients may be more sensitive to nicardipine effects because of impaired renal and/or hepatic function. It is recommended to provide a continuous infusion of nicardipine starting at the dose of 1 to 5 mg/h, depending on the blood pressure and clinical situation. After 30 minutes, depending on the effect observed, the rate should be increased or decreased by increments of 0.5 mg/h. The rate should not exceed 15 mg/h.

Paediatric population

The safety and efficacy in low birth weight infants, newborns, nursing infants, infants, and children has not been established.

Nicardipine should only be used for life-threatening hypertension in paediatric intensive care settings or post-operative contexts.

Initial dose: In case of emergency, a starting dose of 0.5 to 5 mcg/kg/min is recommended.

Maintenance dose: The maintenance dosage of 1 to 4 mcg/kg/min is recommended.

Nicardipine should be used with particular caution in children with renal impairment. In this case, only the lowest dose should be used.

Pregnancy

It is recommended to provide a continuous infusion of nicardipine starting at 1 to 5 mg/h, depending on the blood pressure and clinical situation. After 30 minutes, depending on the effect observed, this rate can be increased or decreased by increments of 0.5 mg/h.

Doses higher than 4mg/h are generally not exceeded in the treatment of pre-eclampsia, however the rate should not exceed 15 mg/h. (See sections 4.4, 4.6 and 4.8)

Hepatic Impairment

Nicardipine should be used with particular caution in these patients. Since nicardipine is metabolized in the liver, it is recommended to use the same dose regimens as for elderly patients in patients with impaired liver function or reduced hepatic blood flow.

Renal Impairment

Nicardipine should be used with particular caution in these patients. In some patients with moderate renal impairment, a significantly lower systemic clearance and higher area under the curve (AUC) have been observed. Therefore, it is recommended to use the same dose regimens as for elderly patients in patients with renal impairment.

Method of administration

Nicardipine should be administered by continuous intravenous infusion only.

Symptoms

Overdose with nicardipine hydrochloride can potentially result in marked hypotension, bradycardia, palpitations, flushing, drowsiness, collapse, peripheral oedema, confusion, slurred speech and hyperglycaemia. In laboratory animals, overdosage also resulted in reversible hepatic function abnormalities, sporadic focal hepatic necrosis and progressive atrio-ventricular conduction block.

Management

In case of an overdose it is recommended to use routine measures including monitoring of cardiac and respiratory function. In addition to general supportive measures, intravenous calcium preparations and vasopressors are clinically indicated for patients exhibiting the effects of calcium entry blockade. Major hypotension can be treated by intravenous infusion of any plasma volume expander and supine position with the legs elevated.

Nicardipine is not dialyzable.

Shelf life

Before opening: 2 years.

After opening: The physicochemical stability of the undiluted solution or diluted in a solution of 5% dextrose in water in a polypropylene syringe has been demonstrated for 24 hours at temperatures of +25°C, away from light. Nonetheless, from a microbiological standpoint, the product should be used immediately.

Do not store above 25°C.

Store in the original container in order to protect from light.

10 ml in a type I brown glass ampoule with an OPC (One Point Cut) break system. Boxes of 5, 10 or 50 ampoules.

Not all pack sizes may be marketed.

Method of use for opening the ampoules:

1. Hold the ampoule, pointing the colour point upward. If liquid is in the upper part of the ampoule, tap on the ampoule to make it descend into the body of the ampoule.
2. Then grasp the end of the ampoule (above the point) and exert pressure to break the ampoule.

Major incompatibilities

A risk of precipitation exists with products presenting a pH in solution greater than 6 (for example, bicarbonate solution, Ringer’s solution, diazepam, furosemide, sodium methohexital, thiopental).

A risk of adsorption of nicardipine exists on plastic materials in devices for infusion in the presence of saline solutions.

Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
