An old man has enlarged prostate. Which of the following may be use to suppress his prostatic growth:
💡 Explanation
## **Core Concept**
The question tests understanding of benign prostatic hyperplasia (BPH) management, focusing on pharmacological suppression of prostatic growth. BPH is a common condition in aging men, characterized by enlargement of the prostate gland. The treatment often involves medications that can reduce the size of the prostate or alleviate symptoms.
## **Why the Correct Answer is Right**
The correct answer, , involves the use of **5-alpha-reductase inhibitors**. These drugs work by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), a potent androgen that promotes prostate cell growth. By reducing DHT levels, these inhibitors can decrease the size of an enlarged prostate over time, thereby alleviating symptoms. Finasteride and dutasteride are examples of 5-alpha-reductase inhibitors used in the treatment of BPH.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option would not be correct because it does not represent a class of drugs used for suppressing prostatic growth.
- **Option B:** This option is incorrect because, while alpha-blockers are used to treat BPH symptoms by relaxing smooth muscle in the prostate and bladder neck, they do not suppress prostatic growth.
- **Option C:** This option is incorrect because it does not accurately represent a treatment approach for suppressing prostatic growth in BPH.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **5-alpha-reductase inhibitors** take several months to show their full benefits in reducing prostate size and alleviating symptoms of BPH. These drugs are particularly useful for men with significantly enlarged prostates and moderate to severe symptoms.
