Cialis (Tadalafil) is a phosphodiesterase type 5 (PDE5) inhibitor which helps improve blood flow in the penis, making it easier for men to achieve and maintain an erection. It belongs to a class of medications known as PDE5 inhibitors.
Cialis works by relaxing the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited. This allows you to get an erection. Cialis has 2 types of action:

However, if your erection lasts for more than four hours, you should consult a doctor for a prescription. Cialis has a longer half-life of 17.5, meaning it takes longer for PDE5 inhibitors to take effect.

If you need to have an erection for more than an hour, it is important to get a prescription from a healthcare professional, as they may be able to advise you on the best dosage.
Cialis (Tadalafil) should not be taken with some medications, such as nitrates for angina (chest pain) or chest pain medication, to treat angina (chest pain or pressure).
