Tadalista Professional (Tadalafil chewable/sublingual-type tablet) is designed to have a faster and more efficient absorption profile than standard swallowed tablets.  Absorption process (step-by-step) 1. Initial disintegration in the mouth The tablet starts dissolving in saliva when placed under the tongue or chewed. This releases tadalafil particles quickly into a dissolved form. 2. Mucosal absorption (partial sublingual route) A portion of the drug may be absorbed through the oral mucosa (under the tongue and inside cheeks). This can allow slightly faster entry into the bloodstream compared to regular tablets. 3. Swallowing + gastrointestinal absorption (main route) Most of the dose is still swallowed with saliva. It then moves to the stomach and small intestine, where the majority of tadalafil absorption occurs. The small intestine is the primary absorption site for oral tadalafil, due to its large surface area and permeability. 4. Systemic circulation After intestinal absorption, tadalafil enters the bloodstream. It reaches peak plasma concentration (Tmax) typically within 2–4 hours (sometimes up to ~6 hours) depending on the formulation.
