Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED), a condition affecting a man’s ability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. This happens because Viagra increases blood flow to the penis.
How Viagra Works
Viagra works by inhibiting an enzyme called phosphodiesterase-5 (PDE5). This allows for increased levels of cGMP, a molecule responsible for relaxing the smooth muscles in the penis, leading to improved blood flow. This increased blood flow is key to achieving and sustaining an erection.
Beyond Erectile Dysfunction
While primarily used for ED, Viagra also has applications in treating pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. In this case, the drug improves blood flow to the lungs, easing breathing difficulties. Always consult your physician for appropriate dosage and treatment.
Remember to discuss any health conditions or medications you are currently taking with your doctor before starting Viagra. A proper medical consultation helps ensure safe and effective use. Your doctor can help determine if Viagra is right for you, and discuss potential side effects and precautions.
