Population pharmacokinetics of intravenous amiodarone in patients with refractory ventricular tachycardia/fibrillation.

A population approach was used to determine the pharmacokinetics of amiodarone in 245 patients receiving intravenous amiodarone for the short-term treatment of refractory, hemodynamically destabilizing, ventricular tachycardia and/or fibrillation. A two-compartment model employing proportional statistical models to estimate intersubject variability and an additive-proportional model to estimate residual error were found to best describe the data. The mean (% coefficient of variation, CV) value for clearance was 0.

Antiarrhythmic and pharmacokinetic evaluation of intravenous recainam in patients with frequent ventricular premature complexes and unsustained ventricular tachycardia.

The pharmacokinetics, antiarrhythmic activity and safety of intravenously administered recainam were evaluated in 15 men and 3 women. All patients had frequent (> 30/hour) ventricular premature complexes (VPCs) and unsustained ventricular tachycardia. Recainam was administered at a loading dose of 4.

Efficacy of isosorbide mononitrate in angina pectoris.

The rapid development of tolerance has limited the applicability of oral and transdermal nitrates in the long-term management of patients with chronic stable angina pectoris. Recent well-controlled trials have demonstrated that asymmetrical, or eccentric, dosing of oral isosorbide mononitrate, in which 20-mg doses are taken at 8 A.M.

Effect of CGP 17/582, a selective beta-adrenoceptor antagonist, on the haemodynamic and hypokalaemic response to adrenaline.

1. CGP 17/582B is a new beta-adrenoceptor antagonist which on experimental studies appears to combine selective beta 1-adrenoceptor blockade with partial agonist activity (ISA). Assessing beta-adrenoceptor selectivity and the degree of partial agonist activity in vivo can be difficult.

Bolus injections of synthetic atrial natriuretic peptide in patients with chronic renal failure or nephrotic syndrome.

The diuretic and natriuretic responses to exogenous synthetic atrial natriuretic peptide (ANP) were evaluated in patients with chronic renal failure (CRF) or nephrotic syndrome (NS). Patients were studied after an oral water load (8 ml/kg in CRF and 20 ml/kg in NS patients). A short intravenous bolus of either a placebo or ANP was administered when urine output was stable.
