Silagra is used to treat erectile dysfunction in men by improving blood flow to the tissues surrounding the penis, which helps increase the ability to achieve a natural erection. Silagra works by inhibiting a specific enzyme that affects the smooth muscles within the blood vessels, allowing them to relax and expand during sexual stimulation. Its effect appears within a relatively short period of time after taking it. Silagra should not be used more than once a day to avoid side effects resulting from an increased dose. It is recommended to take it on a semi-empty stomach to get the maximum benefit. Caution should be taken in the case of heart disease or taking other medications that affect blood pressure.
