Respiratory Arrest as Main Determinant of Toxicity due to Overdose with Different β-Blockers in Rats
Publikováno v:
Acta Pharmacologica et Toxicologica. 57:352-356
Propranolol, timolol and sotalol were compared regarding their toxicological effects on the cardiovascular and respiratory system. Each drug was administered intravenously to anaesthetized spontaneously breathing and artificially ventilated rats. Aft

Potential indices of myocardial contractility derived from aortic blood flow, measured by means of electromagnetic flowmetry, were evaluated in rats under different ventricular loading conditions and were compared with the familiar contractility inde

Propranolol, timolol and sotalol were compared with respect to their cardiotoxic properties in isolated, spontaneously beating rat hearts. Propranolol and timolol induced a dose-dependent decrease in myocardial contractility. A high dose of sotalol h

Propranolol, timolol and sotalol were compared regarding their cardiotoxic properties in isolated, perfused and catecholamine depleted rat hearts. Catecholamine depletion was performed in order to exclude interference of the drugs with beta-adrenergi

Artificially ventilated anesthetized dogs were given imipramine 7.5 mg/kg/hr i.v. In the first group (n = 6) mechanical cardiac activity was no longer detectable after a cumulative dose of 20.0 +/- 6.6 mg/kg (mean +/- sd). When aortic flow had decrea
