Today it is the second most popular drug, after Kamagra Australia online, which is widely used for the treatment of erectile dysfunction. These pills were developed by the large pharmaceutical company Eli Lilly and the YCOS corporation.
The mechanism of action of Cialis is almost identical to Viagra and is provided by inhibiting phosphodiesterase type 5 (FDE5), which metabolizes 3′,5′-cyclic guanosine monophosphate (GMP), which is responsible for a healthy erection. In patients with reduced potency, HMF is too low to provide the necessary penile strength for intercourse. A popular method has been used to maintain adequate levels of HMF, which is to inhibit the enzyme and break down HMF.

Cialis is considered more potent than Viagra because it has a half-life of 17, 5 hours and a maintenance time of about 36 hours to achieve an erection.
Side effects of the drug are:

severe dizziness;
headaches;
blood rush to the head;
Flu symptoms (e.g., nasal congestion);
nausea;
impaired perception of colors;
diarrhea;
Back, joint, and abdominal pain.
Cialis has the same indications and contraindications as Viagra and is used only as prescribed by an andrologist.
