Buy Viagra 100 mg

Viagra (Sildenafil) is a well-known medication used primarily to treat erectile dysfunction and pulmonary arterial hypertension. It works by selectively inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP). cGMP promotes smooth muscle relaxation in the corpus cavernosum, allowing increased blood flow to the penis during sexual stimulation, leading to an erection. Viagra requires sexual arousal to be effective and does not cause erections without it. It is available in multiple dosages, including 25mg, 50mg, and 100mg tablets.

Kamagra also contains Sildenafil citrate, the same active ingredient found in Viagra, but is often sold as a cheaper, unlicensed alternative. Kamagra comes in various forms, including tablets, gels, and jellies, and is popular in online markets. Because Kamagra is not licensed in many countries, its quality and safety may not be guaranteed, making it a riskier choice compared to branded Viagra.

Both medications are prescription drugs and should be used under supervision, especially due to risks like sudden drops in blood pressure when combined with nitrates. Side effects of Sildenafil include headaches, flushing, nasal congestion, dizziness, and digestive upset. It is important not to use Viagra and similar sildenafil products concurrently with other brands meant for pulmonary hypertension, such as Revatio.

Viagra effects start typically within 30 minutes and can last for several hours. It is best taken prior to sexual activity per medical advice. Kamagra can be bought online with cash on delivery options, but caution is advised due to possible counterfeit products.
