Evaluation and Comparison of the Preventive Role of Nebivolol and Alpha- Tocopherol in Testosterone-Induced Benign Prostatic Hyperplasia in Rats

Abstract

Objective: To evaluate and compare the preventive role of Nebivolol and Alpha Tocopherol on testosterone-induced benign prostatic hyperplasia in rats. Study Design: Laboratory-based experimental study Place and Duration of Study: Department of Pharmacology and Pathology, Army Medical College, Rawalpindi, in collaboration with National Institute of Health (NIH), Islamabad Pakistan, from Dec 2021 to Jun 2022. Methodology: One hundred fifty healthy male Sprague-Dawley rats were procured from the NIH, Islamabad. They were placed into five groups, each with 30 rats. Results: Out of a total 150 sample of five groups, the mean prostatic index in Group-A, Group-B, Group-C, Group-D, and Group-E were 1.49±0.09, 2.35±0.48, 1.87±0.11, 1.72±0.04 and 1.68±0.08 respectively (p-value< 0.001). Mean Prostate Specific Antigen in Group-A, Group-B, Group-C, Group-D and Group-E was 0.19±0.02, 0.23±0.01, 0.18±0.02, 0.18±0.02 and 0.16±0.02 respectively (p-value< 0.001). On gross examination, in Group-A, all (100%) prostate samples were normal-sized. In Group-B, all (100%) prostate samples were enlarged. In Group-C, 53.3% were mild, and 47.7% of samples were moderately enlarged. In Group-D, 73.3% of samples were mildly enlarged, and 26.7% were moderately enlarged. In Group E, 26.7% of samples were normal, and 73.3% were mildly enlarged (p-value< 0.001). Conclusion: Prostatic index is markedly declined following treatment with the combination of Nebivolol and Alpha-Tocopherol. There is also a declining trend in Prostate Specific Antigen following treatment with a combination of Nebivolol and Alpha-Tocopherol.
