How Does Viagra Work?Viagra works by relaxing muscles found in the walls of blood vessels, thereby increasing blood flow to specific areas of the body3. It is primarily used to treat erectile dysfunction in men. The active drug in Viagra is sildenafil, which belongs to a group of drugs called phosphodiesterase-5 inhibitors.
The mechanism of Viagra involves a protein called cyclic guanosine monophosphate (cGMP). When cGMP is released, it causes more blood to flow into the penis, leading to an erection. Another protein called phosphodiesterase-type 5 (PDE-5) breaks down cGMP, stopping the erection. In people having difficulty with erections, PDE-5 may work too quickly. Viagra works by blocking PDE-5 from working, allowing blood flow to the penis to occur and not be stopped by PDE-5.
Warnings and PrecautionsIt’s important to note that some medicines can cause unwanted or dangerous effects when used with Viagra. For instance, taking Viagra with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Therefore, it is crucial to tell your doctor about all your current medicines, especially riociguat (Adempas) and nitrates.
Moreover, Viagra should not be used if you are allergic to sildenafil, or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas)3. It is also advised to avoid Viagra if you have heart disease or heart rhythm problems, coronary artery disease, high or low blood pressure, liver or kidney disease, a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia, a bleeding disorder such as hemophilia, a stomach ulcer, retinitis pigmentosa (an inherited condition of the eye), a physical deformity of the penis (such as Peyronie’s disease), or if you have been told you should not have sexual intercourse for health reasons.
ConclusionViagra is a powerful medication that has helped many men overcome erectile dysfunction. However, like all medications, it should be used responsibly and under the guidance of a healthcare professional. Always consult with your doctor before starting any new medication.
