There has been one reported case of massive overdosage with nifedipine extended-release tablets. The main effects of ingestion of approximately 4800 mg of nifedipine extended-release tablets in a young man attempting suicide as a result of cocaine-induced depression was initial dizziness, palpitati...
Initiate drug at the low end of the dosage range; may increase dosage every 2–4 weeks until BP controlled, maximum dosage reached (3 mg/kg [up to 120 mg] daily, given in 1 or 2 divided doses), or adverse effects occur.AdultsAngina...
distinguished from the true extended-release preparations available in some countries that allow dosage once daily. doses of nifedipine are dependent upon the formulation used; they may need to be reduced in the elderly or those with impaired liver function. for hypertension a long-acting ...
Peak serum concentrations averaged 45 micrograms/l, attained 2.7 h after dosage. The mean elimination half-life was 5.9 h (range: 3-12 h). Blood pressure, ventricular rate, and echocardiographically-determined rate of circumferential fiber shortening did not differ between placebo and nifedipine ...
