Fildena Double 200 mg is a medication used primarily for the treatment of erectile dysfunction. Its active ingredient is Sildenafil Citrate, which works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), thereby increasing blood flow to the penis during sexual stimulation. Regarding its effect on blood coagulation, Sildenafil (the active ingredient) primarily affects the cardiovascular system by dilating blood vessels, particularly those in the genital area. This mechanism is unrelated to blood coagulation pathways directly involved in clotting processes. In general, Fildena Double 200mg does not have a direct effect on blood coagulation factors or platelet function. Therefore, it is not expected to influence clotting times or other aspects of blood coagulation in individuals using this medication for erectile dysfunction. However, it's essential to consult a healthcare provider for personalized medical advice, especially if there are specific concerns or existing medical conditions related to blood clotting or cardiovascular health.
