Erectile dysfunction medication with rapid absorption belongs to which class?

• A. PDE5 inhibitors
• B. SSRIs
• C. Beta blockers
• D. Calcium channel blockers

Answer: (A)

PDE5 inhibitors. These drugs work by blocking the enzyme phosphodiesterase type 5, which normally breaks down cGMP. When sexual stimulation occurs, nitric oxide releases, increasing cGMP and causing smooth muscle relaxation in the penile tissues to allow an erection. By inhibiting PDE5, these medications prevent cGMP breakdown, amplifying the natural process and helping achieve an erection with arousal. They typically have rapid absorption after oral dosing, with onset often within 30–60 minutes (some agents can be even faster). This class is specific to facilitating erections, unlike SSRIs, beta blockers, or calcium channel blockers, which do not treat ED and can sometimes contribute to erectile difficulties.
