Summary This study was designed to evaluate the influence of two calcium channel blockers, verapamil and nifedipine, on skin flap survival. These agents were selected because they inhibit the passage of calcium through calcium selective channels in the plasma membrane, thereby blocking calcium mediated electromechanical coupling in contractile tissue and resulting in peripheral arterial vasodilation. Three groups of pigs were used in this study. All skin flaps in this study were 3 cm wide and 12 cm long. The first group (10 flaps) served as controls with no pharmacologic manipulations. Pigs in group II (15 flaps) received verapamil (80 mg orally, three times a day) for 7 days postoperatively. Pigs in group III (15 flaps) received nifedipine (10 mg orally, three times a day) for 7 days postoperatively. Statistical analysis of the results demonstrated that both verapamil and nifedipine resulted in significant enhancement of skin flap survival. The increased survival of the skin flaps produced by nifedipine as compared to verapamil was statistically significant.
