title: [Antiedema effects of basic nonsteroidal anti-inflammatory drugs that are not inhibitors of prostaglandin biosynthesis].
abstract: Antiedema effects of basic nonsteroidal anti-inflammatory drugs that don't inhibit prostaglandin biosynthesis were investigated with carrageenin-induced hind paw edema in rats. Locally administered mepirizole, tiaramide.HCl and aminopyrine, the basic nonsteroidal anti-inflammatory drugs, didn't show any suppression against the edema formation. In the case of indomethacin, phenylbutazone and ketoprofen, inhibitors of prostaglandin biosynthesis, they inhibited the edema formation. Inhibitory effects of orally and subcutaneously administered basic nonsteroidal anti-inflammatory drugs such as tiaramide.HCl and benzydamine on the edema formation were more potent in fasted rats than in nonfasted rats. In the case of acidic nonsteroidal anti-inflammatory drugs such as indomethacin and ibuprofen, their inhibitory activities were almost the same in both the fasted rats and nonfasted rats. These results suggest that the site of action of the basic nonsteroidal anti-inflammatory drugs such as tiaramide.HCl and mepirizole is not the inflamed site, and certain systemic effects may contribute to the anti-edema effects.
