How Does Viagra Work? Viagra belongs to a group of drugs called phosphodiesterase-5 inhibitors23. It functions by blocking the action of a protein in your body known as phosphodiesterase-type 5 (PDE-5). This protein is responsible for breaking down the molecules that normally cause an erection3. By inhibiting PDE-5, Viagra helps an erection occur by allowing certain muscles in the penis to relax and the penis to fill with blood. Uses of Viagra While Viagra is most commonly used to treat erectile dysfunction in men, it is also used to treat pulmonary arterial hypertension and improve exercise capacity in both men and women1. Another brand of sildenafil is Revatio, which is used specifically for this purpose. Warnings and Precautions It’s important to note that Viagra can interact with certain medications, particularly nitrates used for chest pain or heart problems, and can cause a sudden and serious decrease in blood pressure. Therefore, it should not be taken concurrently with these medications. Additionally, Viagra can cause certain side effects, including a painful or prolonged erection lasting longer than 4 hours. In such cases, it’s crucial to seek emergency medical attention. Conclusion Viagra has proven to be an effective treatment for erectile dysfunction and pulmonary arterial hypertension. However, like all medications, it should be used responsibly and under the guidance of a healthcare professional.
