Suction

After taking Cialis Tadalafil Tablets inside Tadalafil Citrate Dosage is rapidly absorbed. The average plasma Cmax is achieved in an average of 2 hours after ingestion. The rate and degree of absorption of Cheap Generic Tadalafil does not depend on the meal, so Tadalafil Citrate Dosage® can be used regardless of the meal. The time of administration (morning or evening) had no clinically significant effect on the rate and degree of absorption.

The pharmacokinetics of Cialis Tadalafil Tablets in healthy individuals is linear in terms of time and dose. In the dose range from 2.5 to 20 mg AUC increases in proportion to the dose.

Distribution

Css in plasma are attained within 5 days while taking Tadalafil Dosage For Erectile Dysfunction 1 time/day.

The average Vd is about 63 liters, which indicates that Cialis Tadalafil 10mg Tablets is distributed in the tissues of the body.

The plasma protein binding of Tadalafil Dosage For Erectile Dysfunction at therapeutic concentrations 94%.

In healthy individuals, less than 0.0005% of the administered dose was found in sperm.

Metabolism
