[Influence of indomethacin and clidanac on the blood pressure lowering effect of beta-blockers]. 1983

H Imai, and M Niwa, and M Nozaki, and K Tsurumi, and H Fujimura

In conscious rabbits, the intravenous administration of pindolol (1.25 mg/kg), propranolol (1 mg/kg) and alprenolol (2 mg/kg) induced a highly significant decrease of mean arterial blood pressure and significant bradycardia. In the same model, the intravenous administration of saline, indomethacin, and clidanac did not affect the mean arterial blood pressure and heart rate. Pretreatment with indomethacin and clidanac reduced the effect of these beta-blockers on the mean arterial blood pressure and had no effect on the heart rate. Treating of the guinea pig heart homogenate with 1 microM indomethacin or clidanac decreased the number of beta-adrenoceptors without changing their affinity. These results suggest that indomethacin and clidanac interfere with beta-adrenoceptor-mediated effects.

D010869 Pindolol A moderately lipophilic beta blocker (ADRENERGIC BETA-ANTAGONISTS). It is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (From Martindale, The Extra Pharmocopoeia, 30th ed, p638) Prindolol,LB-46,Visken,LB 46,LB46
D011433 Propranolol A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
