BASIC CONCEPTS

1. How do DHT inhibitors work to reduce benign prostatic hyperplasia?

ANS:  C

DHT inhibitors work directly on the prostate gland. They are a “counterfeit” drug that looks like testosterone and binds to the enzyme that normally converts testosterone to DHT, its most powerful form. This counterfeit drug cannot be converted to DHT; and, while it is bound to the enzyme, the enzyme is not available to convert the real testosterone to DHT. With much less DHT in the prostate, the cells in the prostate gland do not receive the signal to grow. As a result, the gland shrinks and puts less pressure on the urethra, allowing better urine flow.

4. What is the most common side effect of drugs used for benign prostate hypertrophy (BPH)?

ANS:  B

Side effects of drugs used for BPH also include erectile dysfunction, decreased seminal fluid, and reduced fertility. The most common side effect of these drugs is a decreased interest in sexual activity.

5. Which test or examination does a patient receive before taking any drug for benign prostate hypertrophy (BPH)?

ANS:  A

The signs and symptoms of BPH are the same as for prostate cancer. Before a drug for BPH is taken, the patient should have a digital rectal examination by his prescriber and have his blood tested for prostate-specific antigen levels to rule out prostate cancer.
