This abstract outline the use of Tamsulosin, a selective α (1A and 1D)-adrenoreceptor blocker, to treat benign prostatic hyperplasia (BPH). The study's background highlights the most prevalent symptoms and prevalence of BPH in elderly men. The research objective and goal are to better understand the mechanism of action, pharmacokinetics, dose, clinical efficacy, safety, and tolerance of Tamsulosin, particularly in its modified release (MR) version. Considering evidence-based medicines have recently been made available, the treatment approach for current cases of benign prostatic hyperplasia has evolved. Considerations including therapeutic benefits, potential for morbidity, likely long-term effectiveness, and expenses must be made before selecting a therapy to relieve symptoms. When individuals with benign prostatic hyperplasia report with symptoms related to the lower urinary tract, the main treatment option is α1-adrenergic receptor antagonists. The technique includes a review of the literature on Tamsulosin's development, discovery, and approval, as well as its pharmacodynamics and pharmacokinetics. The findings show that Tamsulosin MR is successful in treating BPH, with a preference for the 0.4mg once-daily dose.
