title: Improvement in blood flow and diabetic neuropathy by thromboxane A2 dual blocker KDI-792.
abstract: We studied the effect of a thromboxane A2 (TXA2) dual blocker KDI-792 on skin blood flow as well as on the peripheral nerve function of nine diabetics with neuropathy. After administration of KDI-792, there was no change in urinary TXB2; however, urinary 6-keto-prostaglandin (PG) F1 alpha increased significantly. Nerve conduction velocity (NCV) and vibration perception threshold (VT) in the four extremities improved significantly, as did deep skin temperature and skin blood flow. The degree of improvement in sensory NCV in the lower extremities correlated significantly with that of deep skin temperature in the toes and the degree of improvement of VT in the lower extremities correlated well with that of deep skin temperature in the soles and of skin blood flow in the toes. Based on these findings, treatment of diabetic neuropathy with a TXA2 dual blocker appears to increase PGI2 production, improving blood flow, and resulting in improvement of nerve functions.
