How Does Viagra Work?
Viagra works by increasing blood flow to the penis to help a man get and keep an erection.gold viagra This is achieved by blocking a protein called phosphodiesterase-type 5 (PDE-5) from working too quickly. Normally, PDE-5 breaks down another protein called cyclic guanosine monophosphate (cGMP), which is responsible for causing more blood to flow into the penis during an erection. By inhibiting PDE-5, Viagra allows cGMP to function properly, thus facilitating and maintaining an erection.

Usage and Dosage
Viagra is taken as needed to treat ED in adults. It is most effective about 1 hour after it’s taken. However, the onset of its effects can vary from person to person, with some people reporting that it begins working within 30 minutes, while for others it may take up to 4 hours.

Side Effects and Safety
Like all medications, Viagra can have side effects. It is important to consult with a healthcare provider to understand these potential side effects and to ensure the medication is taken safely.

Cost and Availability
While the cost of Viagra can start at $80 per dose, the generic version, sildenafil, can cost as little as $25. It is important to ensure that the prescription is filled with the brand-name medication if that is what the doctor has prescribed.

In conclusion, Viagra has been a significant advancement in the treatment of ED. However, as with any medication, it is important to use it responsibly and under the guidance of a healthcare provider.
