Summary and background: Goals and Purpose
Tadalafil is the active ingredient used in this medication. It is primarily used to treat erectile dysfunction in adult men.
Sublingual forms, such as dissolving tablets or films, are designed to melt under the tongue and may reach the bloodstream more quickly than tablets that are swallowed. Sexual stimulation is still required to achieve an erection.
Typical single-unit strengths discussed for sublingual presentations are around 20 mg, but strengths can vary by product or compounding. Standard oral tadalafil tablets are available in 2.5 mg; 5 mg; 10 mg; and 20 mg.
