Background: To evaluate the drug prescription patterns for men diagnosed with benign prostatic hyperplasia (BPH) in Korea.
Methods: We extracted the data of 3% of the national patient samples including men aged ≥ 40 years between 2012 and 2017 from the Health Insurance Review and Assessment database and investigated the drugs prescribed for men with the BPH code N40. Men with a diagnosis of BPH but not receiving treatment were excluded. The primary outcome was the drugs prescribed and the changes in drug prescription pattern over 6 years for men first diagnosed with BPH.
Results: Alpha blockers were the most commonly prescribed drugs in men with BPH, and tamsulosin was the most common. The proportion of prescriptions increased steadily. The number of prescriptions for anticholinergics (ACH) increased, but decreased with the start of mirabegron prescriptions in 2015. Prescriptions of mirabegron are increasing rapidly and replacing ACH. Based on the prescription pattern by drug category, alpha blocker monotherapy decreased, whereas combination therapies such as alpha blocker + 5-alpha-reductase inhibitors (5ARI), and alpha blocker + 5ARI + ACH increased steadily. As for the number of prescriptions by drug ingredient, tamsulosin monotherapy was the most common, and the combination therapy of tamsulosin and mirabegron increased.
Conclusion: Alpha blockers were the most commonly prescribed drug for men first diagnosed with BPH in Korea from 2012 to 2017, and tamsulosin was the most common alpha blocker. Prescriptions of combination therapy and mirabegron are gradually increasing.
