Filitra 20 mg contains sildenafil citrate, which is the same active ingredient found in Viagra. Both medications are used to treat erectile dysfunction (ED) by helping to increase blood flow to the penis, allowing for a stronger and longer-lasting erection in response to sexual stimulation. Key Points About Filitra 20 mg and Sildenafil Citrate: Filitra is a generic version of sildenafil citrate. It's commonly sold under brand names like Viagra, but Filitra is typically less expensive. Sildenafil citrate works by inhibiting the enzyme PDE5, which normally breaks down a substance called cGMP. By inhibiting PDE5, sildenafil increases the levels of cGMP, leading to relaxed smooth muscle and increased blood flow to the penis. The dosage (e.g., 20 mg) indicates the strength of the medication, with Filitra 20 mg being a moderately high dose compared to the more commonly prescribed 50 mg or 100 mg doses of sildenafil. Differences: Brand vs. Generic: Filitra is a generic version of sildenafil, while Viagra is a brand-name drug. The active ingredient is the same, but generics like Filitra may vary in price, appearance, and inactive ingredients. Manufacturers: Filitra is produced by different pharmaceutical companies, whereas Viagra is specifically manufactured by Pfizer. Usage: Filitra 20 mg should be taken about 30 minutes to 1 hour before sexual activity. It usually remains effective for about 4-6 hours, similar to Viagra. Like sildenafil, it is typically recommended to avoid high-fat meals and excessive alcohol consumption when taking Filitra, as these can reduce its effectiveness.
