Wound healing potential of topical amlodipine in full thickness wound of rabbit.

BACKGROUND

Wound healing is a complicated and integrated process. Researches have indicated the wound healing effects of calcium channel blockers in animal models in recent years.

OBJECTIVES

The aim of this study was to evaluate the wound-healing activity of amlodipine as a calcium channel blocker and combination of amlodipine with phenytoin on excisional cutaneous wound models in rabbit.

MATERIALS AND METHODS

Animals were divided into 5 groups (n = 5). The control group was treated topically with eucerin. The untreated control group received no healing agent. The reference standard group was treated with phenytoin1%. A treatment group was treated with amlodipine 1%. The last group was treated with combination of amlodipine1% and phenytoin 1%.

RESULTS

Results indicated significant difference between days needed for complete healing in both of the treatment groups. Wound closure was completed on 13th day and 9th day in amlodipine and combination groups respectively.

CONCLUSIONS

In conclusion, calcium channel blockers can be used to enhance wound healing, especially if this treatment becomes with phenytoin. Further studies are needed to find out the mechanism of this healing effect.
