Wound healing is a major problem in diabetic patient. Sildenafil citrate was earlier reported as a pro-angiogenic agent found to stimulate angiogenesis. We decided to investigate if oral administrations of sildenafil citrate in type I diabetic rats will enhance wound healing. The study was performed using fourty two rats (42) weighing between 139-225 grams. The rats were grouped A-G, six (6) rats per group. Wound area of 1.5 by 1.5 cm2 was created at the dorsal surface of each rat under sedation with ketamine and local anaesthetic (lignocaine). Type I diabetes was induced using Alloxan monohydrate at dose rate of 130 mg/kg. Sildenafil citrate was administered at a dose rate of 50 mg/kg orally daily for 21 days and 10 international units of insulin was administered intraperitoneally to the control group once. Blood glucose and platelet count were significantly (p0.05) decrease as compared to day 3 in diabetic rats. We concluded that oral administration of sildenafil citrate at dose rate of 50 mg/kg did not significantly enhance wound healing in diabetic rats.
