RESUMO

The need for a nonsteroidal anti-inflammatory agent effective in rheumatoid arthritis, osteoarthritis, gout, ankylosing spondylitis and related diseases with reduced side effects when compared to existing drugs led us to develop naproxen: d-2-(6'-methoxy-2'-naphthyl)-propionic acid. This new agent is a highly effective anti-inflammatory, analgetic, and antipyretic agent in the rodent administered orally. In a rat paw edema test for anti-inflammatory activity naproxen was 55 times more active than aspirin. Analgetic activity was assessed by three different assay procedures. In the mouse phenylquinone writhing test naproxen was 7 times as effective as aspirin. In the rat yeast-induced paw edema and the rat carrageenin paw edema analgetic assays the test compound was 10 and 20 times more effective than aspirin, respectively. A yeast-induced pyresis model in the rat indicated that naproxen was 22 times more potent than the standard aspirin. The relative potency of naproxen to phenylbutazone and indometacin is presented.

RESUMO

PIP: Total effective estrogenicity of several human oral contraceptives was investigated through a method determining uterine weight in immature rats. The preparations, normally given to human females in tablet, form were Norinyl-1 (.05 mg mestranol, 1mg norethindrone), Norinyl-2 (.10 mg mestranol, 2 mg norethindrone), Ovulen (.10 mg mestranol, 1mg ethynodiol diacetate), Enovid-E (.10 mg mestranol, 2.5 mg norethynodrel), and Enovid-5 (.075 mg mestranol, 5mg norethynodrel). Each products was administered in total doses of .0025, .005, and .01 of a tablet. Each dose had 3 trials, approximately 10 mice to a trial. Each mouse was given the compound in .2 ml aqueous vehicle orally, daily for a 3-day period so that the sum of the daily doses equaled 1 of the tablet fractions above. Autopsy, on Day 4, discovered the ratio of mg uterus/gm body weight. A .0025 fraction of a tablet of Norinyl-1 produced a mean uterine ratio of 1.79, while control (untreated) mice had a mean ratio of 1.06. Norinyl-2, Ovulen, Enovid-5 and Enovid-E, judging from the corresponding increases in ratios from the control ratio, were found to be 2.1, 2.7, 6, and 8 times, respectively, more estrogenic than Norinyl-1. The relatively high estrogenicity of the Enovids is probably due to the conversion of norethynodrel to estrogenic compounds.^ieng
