Which of the following best describes a key effect of Sildenafil on the body?

• A. Enhances glucose metabolism.
• B. Improves cholesterol levels.
• C. Enhances erectile function and pulmonary vasculature relaxation.
• D. Reduces muscle cramps.

Answer: (C)

Sildenafil is specifically designed to enhance erectile function by increasing blood flow to the penis, thus facilitating an erection in response to sexual stimulation. This is achieved through its action as a phosphodiesterase type 5 (PDE5) inhibitor, which leads to the relaxation of blood vessels in the corpus cavernosum of the penis. Additionally, Sildenafil is used to treat pulmonary hypertension because it relaxes the blood vessels in the lungs, improving blood flow and reducing the workload on the heart. The dual action on both erectile function and pulmonary vasculature relaxation makes option C the most accurate description of Sildenafil's key effects on the body.
