To treat erectile dysfunction (ED) healthcare providers prescribe Cialis medicines. Cialis has been approved by the FDA for its benefits in overcoming erection difficulties. They help restore a healthy erection function.

These medicines are available in the form of pills. As per the Healthline website, a single pill takes around 30 minutes to 2 hours to become fully active in the system. The effect of the pill can last for up to 36 hours or even more.

Cialis pills are popular in the ED drugs category because of their prolonged effective time. No other ED drugs can provide such long-term effectiveness as Cialis drugs.

If you are looking for prolonged effectiveness, then you can choose Cialis over others. This prolonged action is provided by the high-dose Cialis pills. One cannot expect small and moderate doses of Cialis to obtain extended effectiveness.

Cialis composition

Cialis medicines are prescribed for treating impotence issues in males. These are the brand name versions of Tadalafil, which means Tadalafil is a generic version of Cialis.

Tadalafil is the active component of Cialis pills. It is responsible for regulating the erection function after the intake of the pill. Tadalafil has a long-lasting effectiveness. It comes under the class of phosphodiesterase type 5 (PDE5) inhibitors.

Tadalafil as a PDE5 inhibitor compound works on improving the erection function by suppressing PDE5 enzymes. It expands the arteries and allows more blood flow inside the penile.

It is a key ingredient of Cialis pills. It increases the flow of blood to the penile and helps alleviate the erection difficulties. Besides, Tadalafil also comes in generic versions like Tadalista.

Mechanism of Cialis action

Cialis works by boosting the blood flow to the penile. After its intake, the pill takes about 30 minutes to 2 hours to begin its action. It does not produce its desired effects in the absence of sexual arousal.

It is not an aphrodisiac that triggers arousal. It is necessary to be sexually stimulated. Only then will the pill kick into action. It helps restore the sexual response during arousal.

After arousal, the effect of the pill prevents the action of PDE5 enzymes. These enzymes make the penile arteries narrow. They decrease the levels of nitric oxide in the arterial walls.

A drop in the levels of nitric oxide causes the arteries to turn hard and narrow. The blood flow to the penile gets hindered as a result. However, Cialis triggers the release of nitric oxide in the penile arteries walls, which increases blood flow to the penile.

An increase in the blood flow to the arteries helps get stronger erections. The effects of the pills remain for longer, which allows spontaneity.

Cialis doses

These pills are available in four different doses. They include – 2.5 mg, 5 mg, 10 mg, and 20 mg. Low dose are represented 2.5 mg and 5 mg, whereas 10 mg and 20 mg are higher doses.

Low doses of these medicines can be taken every day to retain their effectiveness. But one must never take higher doses of Cialis every day. A higher dose of these pills is not suitable for daily use because of their prolonged effectiveness.

Taking high-dose pills more than once within 24 hours can potentiate the risk of overdosing. Too much Cialis can increase the risk of side effects.
