Cialis, whose active substance tadalafil falls into the group of medications known as phosphodiesterase type 5 (PDE5) inhibitors. Cialis is mainly used to treat erectile dysfunction (ED) in men, but it is also prescribed to treat benign prostatic hyperplasia (BPH), also known as enlarged prostate, and in some cases for pulmonary arterial hypertension.
The action of Cialis is aimed at relaxing the blood vessels in the penis, which increases blood flow to the penis during sexual stimulation. This helps a man get and keep an erection. One of the advantages of Cialis over others ED drugs is its long duration of action. Cialis can remain effective for up to 36 hours, which has earned it the nickname "the weekend pill." This gives users more flexibility than medications that must be taken within a shorter time frame.
It is important to use Cialis only with a doctor's prescription and to follow the instructions of a healthcare provider. Abuse or improper use may lead to side effects such as headache, back pain, muscle aches, stomach upset, flushing, or in rare cases, more serious side effects such as a sudden decrease or loss of vision or hearing.
