Pharmacokinetics

The pharmacokinetics of Tadalafil For Erectile Dysfunction in patients with erectile dysfunction is similar to the pharmacokinetics of Cialis Tadalafil 20 Mg Tablets in persons without erectile dysfunction. Absorption After taking Buy Tadalafil Canada inside Buy Tadalafil Canada is rapidly absorbed. The average plasma Cmax is achieved in an average of 2 hours after ingestion. The rate and degree of absorption of Tadalafil Dosage For Erectile Dysfunction does not depend on the meal, so Tadalafil 10mg 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 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 Cheap Generic Tadalafil 1 time/day. The average Vd is about 63 liters, which indicates that Cialis Tadalafil 20 Mg Tablets is distributed in the tissues of the body. The plasma protein binding of Tadalafil 5mg India at therapeutic concentrations 94%. In healthy individuals, less than 0.0005% of the administered dose was found in sperm. Metabolism Tadalafil Tablets Usp 20 Mg 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 Tadalafil Generic Cialis 20mg when administered is 2.5 l/h, and the average T1/2 - 17.5 h. Tadalafil Citrate Dosage 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 Tablets Usp 20 Mg when administered, which was expressed in an increase in AUC by 25% compared with healthy individuals aged 19 to 45 years. This difference is not clinically significant and does not require dose adjustment. In patients with renal insufficiency of mild to moderate severity dose adjustment is not required. Due to the increased exposure of Cialis Tadalafil 20 Mg Tablets (AUC), patients with severe renal insufficiency are not recommended to use Cialis Tadalafil Tablets. The pharmacokinetics of Cialis Tadalafil Buy Online in patients with weak and moderate hepatic insufficiency is comparable to that in healthy individuals In patients with severe hepatic insufficiency (class C according to the child-Pugh classification) data are not available.
