Why Is Filitra Sometimes Referred To As A PDE5 Inhibitor?

[Robert Tanser]

Filitra is sometimes referred to as a PDE5 inhibitor because it contains vardenafil as its active ingredient, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors work by blocking the action of the enzyme phosphodiesterase type 5, which plays a role in regulating blood flow in the penis.

When a man is sexually stimulated, nitric oxide is released in the penis, which activates an enzyme called guanylate cyclase. This enzyme increases levels of cyclic guanosine monophosphate (cGMP), leading to relaxation of the smooth muscles in the penis and increased blood flow. PDE5 enzymes break down cGMP, leading to a decrease in blood flow and loss of erection.

By inhibiting the action of PDE5 enzymes, medications like Filitra prevent the breakdown of cGMP, allowing it to accumulate and maintain the relaxation of smooth muscles in the penis. This leads to improved blood flow to the penis, resulting in an erection that is sufficient for sexual activity.

Other medications commonly known as PDE5 inhibitors include sildenafil (Viagra) and tadalafil (Cialis). These medications work in a similar way to Filitra, although they may have different durations of action and side effect profiles.

Overall, the term “PDE5 inhibitor” is used to describe medications that block the action of phosphodiesterase type 5 enzymes, leading to improved erectile function by enhancing blood flow to the penis.
