Filitra 40 mg comes in tablet form because the active medicine (vardenafil 40 mg, in many Filitra products) needs to be taken as a measured oral dose that can be absorbed through the digestive system and enter the bloodstream. Tablets are commonly used for medicines like vardenafil because they: Allow a precise dose to be delivered. Are easy to store, carry, and take. Provide a predictable way for the body to absorb the medicine. Filitra is used for erectile dysfunction (ED) by helping increase blood flow to the penis during Filitra 40 mg stimulation. A note about dose: 40 mg vardenafil is higher than the commonly used vardenafil doses in many countries, so it is important to use it only if prescribed or recommended by a healthcare professional. Possible side effects include: Headache Flushing Dizziness Indigestion Nasal congestion Do not take it with nitrate heart medicines (such as nitroglycerin), as the combination can cause a dangerous drop in blood pressure. If you mean “why is it a tablet instead of another form (like capsule or gel)” or you want to compare Filitra 40 mg with sildenafil/tadalafil, I can explain that too.
