Antiexudative Effects of Finasteride and a New Pyrazolo[C]Pyridine Derivative GIZh-72 in Acetic Acid-Induced Experimental Peritonitis.

ABSTRACT

It was shown that finasteride, a 5α-reductase inhibitor (50 mg/kg, intraperitoneally) produced analgesic and antiexudative effects in experimental peritonitis induced by intraperitoneal injection of 1% acetic acid. These results agree with published data on its anti-inflammatory properties and ability to potentiate the analgesic effect of morphine in rodents. New pyrazolo[C] pyridine derivative GIZh-72 (4,6-dimethyl-2-(4-chlorphenyl)-2,3-dihydro-1H-pyrazolo[4,3-C]pyridine-3-on, chloral hydrate) injected intraperitoneally in doses of 20-80 mg/kg produced dose-dependent antiexudative effects, but exhibited no analgesic properties.
