Analysis of Ornidazole Injection in Clinical Use at Post-marketing Stage by Centralized Hospital Monitoring System.

This study aims to analyze the clinical use of ornidazole injection at the post-marketing stage by centralized hospital monitoring system method, and investigate its widespread use in patients, in order to regulate and guide the rational drug use, improve the drug specificity and provide a basis for drug therapy. The study adopts a prospective, multi-center, large sample size, centralized hospital monitoring system. We selected five leading hospitals in Hubei province, and observed the inpatients who received the ornidazole injection from July 1, 2015 to October 31, 2015. The basic information of patients was recorded, as well as the drug use and adverse events. The statistical analysis was performed based on these data. A total of 4396 individuals were enrolled in this study, most of them were middle-aged female patients and the ornidazole injection was mainly used as prophylactic prior to surgery to prevent the infections, and surgical treatment of anaerobic infections, abdominal infections and pelvic infections. The irrational drug use existed mainly in the prescribing and administration process, including unreasonable dosing frequency, rapid intravenous drip speed and extended duration of drug use. Eleven cases of adverse reactions were collected during the monitoring, incidence rate of adverse reactions was 2.5‰; adverse drug reactions occurred within 30 min. The study results fully reflected the usage of ornidazole injection in the real world. Based on the study, we calculated the adverse reaction incidence of ornidazole and identified the risk factors which may affect the safety of ornidazole injection. Study results strongly recommend that the manufacturers should publish standards for inpatient use and doctors should prescribe with caution accordingly.

Clinical application analysis of andrographolide total ester sulfonate injection, a traditional Chinese medicine licensed in China.

Andrographolide total ester sulfonate (ATES) injection is one of the products of traditional Chinese medicine (TCM) currently used against viral infection in China. ATES injection was approved for manufacturing and marketing in January 2002. It is indicated for acute respiratory infections, tonsillitis, chronic obstructive pulmonary disease, influenza, foot and mouth disease, bronchiolitis, herpangina, mumps, infectious mononucleosis and psychosis. However, its usage also carries risk. We investigated the use of ATES at the Wuhan Union Hospital from January 2014 to December 2014 and evaluated its real-world clinical application using the hospital centralized monitoring method. A total of 848 cases were enrolled in this study. In these cases, it was mainly used for postoperative anti-inflammation and treating upper respiratory infection, pneumonia and bronchitis. Among them, 39.86% were contraindicated. Irregular medication of adults and children accounted for 1.91% and 23.38%, respectively. Improper choice of solvent accounted for 3.18%. The choice of intravenous drip versus aerosol inhalation was reasonable. A case of adverse events (AEs) was observed in the monitoring period, and the incidence of adverse drug reaction (ADR) of ATES injection was 0.12%. ATES injection in our hospital is relatively safe with a low incidence of adverse reactions. The study assesses the clinical usage and adverse reactions of ATES injection, and provides suggestions for rational use in clinical practice.
