Fact checkedWhat are PDE5 Inhibitors (Erectile Dysfunction)?
PDE5 inhibitors are medications used to treat erectile dysfunction (ED) by improving blood flow to the penis. These drugs help men achieve and maintain an erection sufficient for sexual activity, addressing a common and often distressing condition.
How do PDE5 Inhibitors (Erectile Dysfunction) work?
PDE5 inhibitors work by blocking the enzyme phosphodiesterase type 5 (PDE5), which can restrict blood flow to the penis. By inhibiting PDE5, these medications:
- Relax the blood vessels in the penis.
- Increase blood flow in response to sexual stimulation.
- Support the natural erectile process.
What conditions do PDE5 Inhibitors (Erectile Dysfunction) treat?
PDE5 inhibitors are commonly used to treat:
- Erectile dysfunction (ED): Difficulty achieving or maintaining an erection.
- Pulmonary arterial hypertension (PAH): High blood pressure in the lungs.
- Benign prostatic hyperplasia (BPH): Improves urinary symptoms in some cases.
Common medications in PDE5 Inhibitors (Erectile Dysfunction)s
Popular PDE5 inhibitor medications include:
- Sildenafil (Viagra): Treats ED with fast-acting results.
- Tadalafil (Cialis): Offers long-lasting effects (up to 36 hours) for ED and BPH.
- Vardenafil (Levitra, Staxyn): Provides effective ED relief with fewer food interactions.
