Pharmacokinetics

The pharmacokinetics of sildenafil 100 mg reveal its rapid absorption in the bloodstream. Upon oral administration, peak plasma concentrations occur within 30 to 120 minutes. This is optimal for those seeking timely erectile response. Bioavailability hovers around 40%, impacted by first-pass metabolism. Distribution is widespread, with binding to plasma proteins reaching approximately 96%. Sildenafil undergoes hepatic metabolism, primarily via cytochrome P450 enzymes CYP3A4 and CYP2C9. The primary circulating metabolite, N-desmethylsildenafil, holds pharmacological activity. However, it accounts for just 20% of sildenafil’s potency. Elimination from the body follows a half-life of four hours. The route of excretion involves both fecal (80%) and renal (13%) pathways. Thus, pharmacokinetic profiles of Fildena ensure both efficacy and safety.

How Should Fildena Be Used?

Fildena should be used as prescribed by a healthcare provider. For effective results, take one tablet approximately one hour before sexual activity. Do not exceed the maximum recommended dose of one tablet per day. Administer Fildena orally with water, avoiding high-fat meals that may delay absorption. Tailor dosing according to individual response and tolerability. Initiating treatment with sildenafil 50 mg is common, with adjustments made based on efficacy and side effects. A void taking Fildena with alcohol, as it may diminish its effectiveness and increase the risk of adverse reactions.

Warning & Precautions

Consult a physician before using Fildena, especially if you have pre-existing cardiovascular conditions. Sildenafil may potentiate the hypotensive effects of nitrates, leading to dangerous drops in blood pressure. Patients with a history of severe vision loss, known as NAION, should approach with caution. Liver or kidney impairment may necessitate dose adjustments. Grapefruit products may interfere with sildenafil metabolism, increasing side effects. In case of sudden hearing loss or vision changes, discontinue use and seek immediate medical attention.

Pregnancy and Breastfeeding

Fildena is not indicated for use in women. However, pregnancy and breastfeeding contexts warrant cautious consideration. There is insufficient data on sildenafil’s effects during pregnancy or lactation. Animal studies do not indicate direct harmful effects on reproductive toxicity. Nonetheless, women of childbearing potential should avoid Fildena due to unknown risks. Clinicians should evaluate the risk-benefit ratio in exceptional circumstances.

Side Effects

Like any medication, Fildena can cause side effects. Common reactions include headache, flushing, dyspepsia, and nasal congestion. These effects are typically mild and transient. Rarely, users may experience dizziness or visual disturbances. Serious but uncommon events include priapism, a prolonged erection requiring medical intervention. Cardiovascular events, though rare, necessitate vigilance in susceptible individuals. An allergic reaction, marked by rash or swelling, requires discontinuation and prompt medical attention.
