The big picture view
Cialis Professional is a trade name sometimes used for products that contain tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor prescribed for erectile dysfunction in adult men. By increasing blood flow to the penis during sexual arousal, tadalafil can help produce and sustain an erection.
Manufacturers and vendors may claim faster onset or longer effects for items marketed as Cialis Professional. In the UK, licensed tadalafil formulations generally work for many people from about 30 minutes after dosing and can have effects lasting up to 36 hours. Rapid onset chewable tablets or ultrafast forms seen on some websites are not the usual MHRA licensed varieties available here.
