Effects of enfenamic acid and its zinc salt on wound-healing

Dose-matched comparison between zinc-salt of enfenamic acid and the parent compound was carried out in experimentally wounded male albino rats bearing either sutured incision, dead-space or excision wounds. Result showed that enfenamic-acid significantly decreased breaking-strength of incision wounds and this effects was totally reversed by zinc present in enfenamic acid-zinc salt. Both the parent compound and the salt had significant granulation suppressant effect in dead-space wounds. In excision wounds epithelization was enhanced by enfenamic acid only. The wound contraction was not affected by either test compound.
