OBJECTIVE: To observe the clinical curative effects of alprostadil combined with calcium dobesilate in type 2 diabetes patients with peripheral neuropathy. METHODS: We randomly divided 120 type 2 diabetes patients with diabetic peripheral neuropathy into two groups. The treatment group was prescribed alprostadil (10 μg, once daily) and oral calcium dobesilate (0.5 g, 3 times daily), and the control group was prescribed alprostadil (10 μg, once daily) for a total treatment duration of 2 weeks. The Michigan Diabetic Neuropathy Score (MDNS) and the Michigan Neuropathy Screening Instrument (MNSI) were used to evaluate differences between the two groups before and after treatment. RESULTS: Following 2 weeks of treatment, the total effective rate in the treatment group was significantly better than that of the control group (p<0.05) and the MDNS and MNSI scores in the treatment group were significantly lower than those in the control group (pCONCLUSION: Combined alprostadil and calcium dobesilate treatment for type 2 diabetic peripheral neuropathy showed good clinical efficacy and an improved curative effect than single alprostadil treatment.
