Pharmacological action
Tadalafil 10mg Dosage for the treatment of erectile dysfunction. Cialis Tadalafil 10mg Tablets is a reversible selective inhibitor of cyclic guanosine monophosphate (cGMP) PDE5. When sexual arousal causes local release of nitric oxide, inhibition of PDE5 by Cialis Tadalafil Buy Online leads to an increase in the concentration of cGMP in the cavernous body of the penis. The consequence of this is the relaxation of the smooth muscles of the arteries and blood flow to the tissues of the penis, which causes an erection.

Absorption After taking Tadalafil 10mg Dosage inside Cialis Tadalafil 10mg Tablets is rapidly absorbed. The average plasma Cmax is achieved in an average of 2 hours after ingestion. The rate and degree of absorption of Buy Tadalafil Canada does not depend on the meal, so Cialis Tadalafil Buy Online 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 Buy Tadalafil Canada 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. The distribution of Css in plasma is achieved within 5 days when taking Cialis Tadalafil 10mg Tablets 1 time/day. The average Vd is about 63 liters, which indicates that Cialis Tadalafil Buy Online is distributed in the tissues of the body. The plasma protein binding of Tadalafil Citrate Dosage at therapeutic concentrations 94%. In healthy individuals, less than 0.0005% of the administered dose was found in sperm. Metabolism Tadalafil Dosage For Erectile Dysfunction is mainly metabolized with the participation of CYP3A4 isoenzyme. The major circulating metabolite is methylethanolamine. This metabolite is at least 13,000 times less active against PDE5 than Cialis Tadalafil Tablets. Therefore, the concentration of this metabolite is not clinically significant. Excretion In healthy individuals, the average clearance of Cheap Generic Tadalafil when administered is 2.5 l/h, and the average T1/2 - 17.5 h. Tadalafil Tablets India is excreted mainly in the form of inactive metabolites, mainly with feces (about 61% of the dose) and, to a lesser extent, with urine (about 36% of the dose). Pharmacokinetics in special clinical cases, protein Binding does not change with impaired renal function. Healthy elderly patients (65 years and more) had a lower clearance of Tadalafil 10mg Dosage when administered, which was expressed in an increase in AUC by 25% compared with healthy individuals aged 19 to 45 years.
