PDE5 inhibitors

PDE5 inhibitors are a class of medications primarily used to treat erectile dysfunction (ED). They work by blocking the enzyme phosphodiesterase type 5 (PDE5), which leads to increased cGMP levels in the penis and enhances blood flow, aiding in the achievement and maintenance of an erection. Common PDE5 inhibitors include sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). These medications should be taken under a doctor’s supervision, and they are most effective with sexual stimulation. Always consult a healthcare provider before use.
