Calcium dobesilate (Doxium) as a prostaglandin synthetase inhibitor in pregnant human myometrium in vitro

Summary This comparative study on the effect of calcium dobesilate and indomethacin on prostaglandin biosynthesis was performed on microsomal fractions of pregnant human myometrium. Both drugs inhibited prostaglandin synthesis, indomethacin being more potent. Calcium dobesilate inhibited, in a dose-dependent manner, the synthesis of 6-oxo-PGF₁, PGF₂, PGE₂ and TXB₂. Its inhibitory action is comparable to that of etamsylate.
