A comparative study on the effect of various pharmacological agents on the survival of skin flaps in the rat.

The effects of chlorpromazine, pentoxifylline, terbutaline, allopurinol, phenoxybenzamine, naftidrofuryl, hydralazine and trimetazidine were investigated on caudally based dorsal flaps. The study was performed on 108 rats, divided in 9 groups of 12 animals each, one of which served as a control group. All treated groups showed a significantly greater survival of the flap than the control group. Comparisons among different groups showed better outcome in those receiving trimetazidine and hydralazine, followed by those receiving naftidrofuryl and phenoxybenzamine.
