Popis: Terazosin, an alpha-adrenergic antagonist, was administered as a 15 mg/ml solution to rats intravenously at a rate of 2 ml/min. Under these conditions the LD50 was 277 mg/kg for males and 293 mg/kg for females. When administered daily for 1 month at dosages of 0, 10, 40 or 150 mg/kg/day, the no-toxic-effect dosage was 40 mg/kg/day. Evidence of toxicity at 150 mg/kg included hypothermia and deaths. Death resulted from acute, exaggerated pharmacologic effects leading to cardiorespiratory failure. Evidence of sympatholytic activity observed at lower dosages included hypoactivity, blepharoptosis, ptyalism and splenic congestion.
