Erectile dysfunction in males may be treated with a medication called Fildena purple pill - Best Pill For Some physical Problem. It improves erections by increasing blood flow to the penis. This pill does not prevent physical transmitted illnesses and does not increase a man's libido. Men of legal age only are allowed to use this supplement. People with preexisting diseases such as heart disease, high blood pressure, liver disease, renal disease, or any other medical condition should not use this medication. Fortune Healthcare of India produces Fildena, a Viagra sibling made of sildenafil citrate and classified as a PDE-5 inhibitor. The pill is effective because it raises nitric oxide levels in the blood, which in turn causes the penile blood vessels to relax and blood flow more freely. The resulting erection may remain stable for four or five hours. Fildena, like other ED medications, may be taken with or without meals, albeit a large meal may slow the pill effectiveness. It is not suggested to drink grapefruit juice while taking this medicine, and it should not be taken with nitrates or nitrites.
