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 body. More specifically, it blocks the action of a protein called phosphodiesterase-type 5 (PDE-5) that breaks down cyclic guanosine monophosphate (cGMP), a molecule that triggers erections by allowing more blood to flow into the penis4. By inhibiting PDE-5, Viagra helps maintain higher levels of cGMP, promoting the ability to achieve and maintain an erection.
Usage and Dosage
Viagra is taken as needed to treat ED in adults. It is most effective about hour after it’s taken, and its effects can last for a few hours. However, the exact timing can vary depending on individual factors, including the user’s overall health and whether they’ve eaten recently.
Warnings and Side Effects
While Viagra is generally safe for most people, it can cause side effects and isn’t suitable for everyone. For instance, it should not be taken by individuals who are allergic to sildenafil or those taking certain other medications, such as nitrates used for chest pain or heart problems. Combining Viagra with these drugs can cause a sudden and serious decrease in blood pressure.
Side effects of Viagra can include headaches, flushing, upset stomach, abnormal vision, nasal congestion, back pain, muscular pain, or nausea. In rare cases, it can cause an erection that won’t go away (priapism), sudden vision loss in one or both eyes, or sudden hearing decrease or hearing loss. Anyone experiencing these symptoms should seek medical attention immediately.
Conclusion
Viagra has revolutionized the treatment of erectile dysfunction since its introduction. However, like all medications, it should be used responsibly and under the guidance of a healthcare professional. Always consult with your doctor or pharmacist for more information.
