One well-known drug for erectile dysfunction (ED) is Filagre, which helps men get and keep a hard erection during intercourse. Sildenafil Citrate, the main active ingredient of Filagra, is also a component of Viagra. It increases blood flow to the penis by relaxing blood vessels. Men react to sexual stimulation more naturally as a result of their better circulation. Depending on personal requirements and the severity of ED, Filagra is available in a number of forms, including as Filagra 100 mg, Filagra Double, and Filagra DXT. Its effects can continue for up to 4 or 6 hours, and it is usually taken 30 to 60 minutes before sexual activity.
