Animal Model
Administration Dosage Frequency Description References
Rats Chronic hyperparathyroidism model 40 mg/kg per day Subcutaneous injection Once daily for 7 days To evaluate the effect of Trapidil on PTH-induced mast cell recruitment to bone surfaces. Trapidil reduced the number of mast cells associated with fibroblasts but increased those associated with osteoblasts. PMC3154003
