Abstract

Background: Dabigatran is the first drug of direct-acting oral anticoagulants in Hatyai Hospital drug list. Since it is a Non-National List of Essential Medicines with increasing amount of use and drug use value each year, the appropriate use of the drug has been reviewed.

Objective: To study the appropriateness of the use of dabigatran in 3 topics as the following 1) accordance with the indications approved by the Food and Drug Administration of Thailand, 2) monitoring of renal function before and during drug use and 3) drug interactions.

Methods: A retrospective descriptive study was performed by using data from electronic databases and medical records of all outpatients who were prescribed dabigatran during 1 October 2019 to 30 September 2021. Data were analyzed statistically by frequency and percentage.

Results: There were 222 cases with 1,294 prescriptions of dabigatran use. It was prescribed in accordance with the indications approved by The Food and Drug Administration of Thailand as follows: non-valvular atrial fibrillation (NVAF) (to reduce the risk of ischemic stroke and systemic embolism) in 137 cases (61.7%) treatment and prevention of venous thromboembolism in 36 cases (16.2%) and 23 cases (10.4 %). Totally, there were 196 cases (88.3%) who were prescribed in accordance with the indications approved and non-approved indications were prescribed in 26 patients (11.7%). There were 205 cases (92.3%) of patients who were assessed renal function before starting dabigatran, while 185 cases (83.3%) were monitored at least one time during the course of treatment. Potential drug interactions were identified in 87 cases (39.2%).

Conclusion: Most dabigatran prescribings were appropriate in terms of indications, renal function monitoring and drug interaction. However, the lack of renal function monitoring and inappropriate indications for use were still found in some patients. Therefore, more management guidelines should be developed to ensure safer and more effective use of drugs.
