Fildena Double 200 Mg acts by inhibiting the enzyme PDE5, which is responsible for breaking down camp—a compound that promotes blood flow to the penis. By inhibiting PDE5, Fildena Double 200 Mg helps to maintain higher levels of camp, allowing for improved blood flow and leading to a firm and sustainable erection. Upon sexual stimulation, Sildenafil encourages the release of nitric oxide, a natural chemical in the body. Nitric oxide relaxes the blood vessels in the penile region, facilitating increased blood flow to the erectile tissues. As a result, men can achieve and sustain an erection during sexual activity. While Fildena Double 200 Mg is generally safe and well-tolerated, certain precautions should be observed. Individuals with a history of heart problems, hypertension, or allergic reactions to Sildenafil should exercise caution. Additionally, it is crucial not to combine Fildena Double 200 Mg with nitrates or alcohol, as this may lead to adverse effects.
