How Prostatic Hyperplasia Medications Work

Prostatic hyperplasia, also known as benign prostatic hyperplasia (BPH), is a non-cancerous enlargement of the prostate gland. As the prostate grows, it can compress the urethra and cause urinary symptoms such as frequency, urgency, nocturia, weak or interrupted urine flow, and straining during urination.

Medication Classes

• Alpha-Blockers: These medications relax the smooth muscle in the prostate and bladder neck, making it easier to urinate. Examples include Tamsulosin and Alfuzosin.

• 5-alpha-reductase inhibitors: These medications reduce the size of the prostate by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone that promotes prostate growth. Examples include Finasteride and Dutasteride.

• Phosphodiesterase type 5 inhibitors: While primarily used for erectile dysfunction, these medications can also help relax the smooth muscle in the prostate and bladder neck, improving urine flow. An example is Sildenafil.

How Medications Relieve Symptoms

The goal of medication therapy for BPH is to relieve urinary symptoms by reducing prostate size or relaxing the muscles involved in urination. By addressing these underlying causes, medications can help improve urine flow, reduce straining during urination, and decrease the frequency and urgency of urination.
