The duration of action of Fildena 50 mg, which contains sildenafil citrate, can vary from person to person and depends on individual factors such as metabolism, overall health, and dosage. In general, the effects of Fildena 50 mg typically last for approximately 4 to 6 hours.

After taking Fildena 50 mg, sildenafil citrate is rapidly absorbed into the bloodstream, with peak plasma concentrations reached within 30 to 120 minutes after oral administration. Once absorbed, sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By inhibiting PDE5, sildenafil increases blood flow to the penis during sexual stimulation, leading to the achievement and maintenance of an erection.

The duration of action of Fildena 50mg may be influenced by factors such as the presence of food in the stomach, concurrent use of certain medications, and individual sensitivity to the drug. Taking Fildena 50 mg with a high-fat meal may delay the onset of action, as the absorption of sildenafil may be slowed down.

It's important to note that Fildena 50 mg does not provide continuous erection, and sexual stimulation is still required to achieve an erection. Additionally, the effects of Fildena 50 mg may diminish over time as the drug is metabolized and cleared from the body.

If you have any questions or concerns about the duration of action of Fildena 50 mg or its use for the treatment of erectile dysfunction, it's essential to consult with your healthcare provider. They can provide personalized advice based on your individual health status and treatment needs.
