Abstract: Objective To provide references for clinical prevention and treatment by analyzing the clinical features and related factors of adverse drug reactions due to alprostadil. Methods The incidences of ADRs caused by alprostadil reported in the hospital from 2010 to 2014 were analyzed in terms of gender, age, primary disease, specification and dosage, the method of administration, clinical manifestation, relevance evaluation, treatment and prognosis. Results Totally, 100 cases of ADR caused by alprostadil were reported. In 100 patients, 56 cases were male, average age was (65.5+1.7) years old, while 44 cases was female, average age was (52.5 + 26.5) years old. Mainly primary disease were fracture (20 cases), nephropathy (19 cases), varicose vein (13 cases). Alprostadil doses were 10 μg·d-1 (2 cases) and 20 μg·d-1 (27 cases). 96 patients were treated with intravenous infusion, 4 cases with intravenous injection. Medication time was 2 d (2.9 + 2.8) d. Clinical manifestations of adverse reactions were mainly cardiac vascular system damage, accounting for 62.4%. In all 100 cases of ADR, 2 cases were "must", 47 cases "very likely", 51 cases "possible". Treatment Methods of adverse reaction were withdrawal, external application, oxygen inhalation, intravenous injection of glucocorticoid. Among the outcomes, 17 cases were cured, 83 cases improved. Conclusion Adverse reactions of alprostadil have occurred from time to time, clinical attention should be paid to the proper preservation and use of alprostadil and alprostadil adverse reactions monitoring.
