What are PDE5 inhibitors?
PDE-5 inhibitors are a class of medications that block the action of an enzyme called phosphodiesterase-5 (PDE-5). This enzyme regulates blood flow in the penis and can interfere with the process of achieving and maintaining an erection. By inhibiting PDE-5, these medications help increase blood flow to the penis, aiding men with erectile dysfunction (ED) in achieving and maintaining an erection.PDE-5 inhibitors are primarily used to treat ED, but they are also effective for other conditions such as pulmonary arterial hypertension (PAH). Common examples of PDE-5 inhibitors include sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra), and avanafil (Stendra). These medications are taken orally and are generally well tolerated, although side effects can occur in some individuals.It's important to note that PDE-5 inhibitors do not work for everyone and are not a cure for ED. They are most effective when used in conjunction with other treatments, such as lifestyle changes and counseling.
