The effects of amlodipine and platelet rich plasma on bone healing in rats.

AIM

The aim of this study was to evaluate the effects of calcium channel blocker (CCB) amlodipine (AML), platelet rich plasma (PRP), and a mixture of both materials on bone healing.

MATERIALS AND METHODS

Fifty-six male Wistar rats were randomly divided into four groups: group A, tibia defect model with no treatment; group B, tibia defect model treated with AML, 0.04 mg daily by oral gavage; group C, tibia defect model treated with local PRP; group D, tibia defect model treated with local PRP and AML, 0.04 mg daily by oral gavage.

RESULTS

At day 21, bone healing was significantly better in groups C and D compared to group A (P<0.05), but comparisons showed no statistically significant difference in group B (P>0.05). At day 30, groups B and C showed no statistically significant difference (P>0.05) compared to group A, but bone healing in group D was significantly better than in group A (P<0.05). Statistically, AML did not affect alkaline phosphatase (ALP) activity at 21 and 30 days (P>0.05), but PRP and AML + PRP increased ALP activity statistically (P<0.05).

CONCLUSION

It can be concluded that AML had neither a positive nor a negative effect on bone healing, but when used in combination with PRP, it may be beneficial.
