The rate and degree of absorption of Tadalafil Generic Cialis 20mg does not depend on the meal, so Tadalafil Cialis From India® 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 Tadalafil For Erectile Dysfunction 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 Cialis Tadalafil Tablets 1 time/day.
The average Vd is about 63 liters, which indicates that Tadalafil 5mg India is distributed in the tissues of the body.
The plasma protein binding of Tadalafil 10mg Dosage at therapeutic concentrations 94%.
In healthy individuals, less than 0.0005% of the administered dose was found in sperm.
Metabolism
Tadalafil 40 Mg Dosage is mainly metabolized with the participation of the CYP3A4 isoenzyme. The major circulating metabolite is methylethanolamine. This metabolite is at least 13,000 times less active against PDE5 than Buy Tadalafil Canada. Therefore, the concentration of this metabolite is not clinically significant.
Breeding
In healthy individuals, the average clearance of Cialis Tadalafil Tablets when administered is 2.5 l/h, and the average T1/2 - 17.5 h. Tadalafil Tablets Usp 20 Mg 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
Binding to proteins does not change with impaired renal function.
Healthy elderly patients (65 years and more) had a lower clearance of Tadalafil Citrate Dosage 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 diabetes mellitus during the use of Cheap Generic Tadalafil AUC was less by about 19% than in healthy individuals. This difference does not require dose selection.
Dosage and administration
Inside. Use of Tadalafil Eli Lilly Tadalafil 40 Mg Dosage according to the indication of erectile dysfunction (ED). For patients with frequent sexual activity (more than 2 times a week): the recommended frequency of intake is daily, 1 time per day 5 mg, at the same time, regardless of food intake. The daily dose can be reduced to 2.5 mg, depending on individual sensitivity.

The duration of treatment is set by the doctor individually. In patients with mild renal insufficiency (creatinine Cl from 51 to 80 ml/min) and moderate (creatinine Cl from 31 to 50 ml/min) dose adjustment is not required. In patients with severe renal failure (Creatinine CL <30 ml/min and hemodialysis): use of Tadalafil Generic Cialis 20mg is contraindicated.
Side effect
Most often: headache, dyspepsia. Possible: back pain, myalgia, nasal congestion, blood flow to the face. Rarely: swelling of the eyelids, pain in the eyes, conjunctival hyperemia, dizziness.
Overdose
Symptoms: with a single appointment to healthy individuals Tadalafil Cialis 20mg at a dose of up to 500 mg and patients with erectile dysfunction - repeatedly up to 100 mg/day, the undesirable effects were the same as when using Tadalafil Citrate Dosage in lower doses. Treatment: in case of overdose, standard symptomatic treatment is necessary. In hemodialysis Cialis Tadalafil 10mg Tablets practically displayed.
Interaction with other drugs
Tadalafil Tablets India is mainly metabolized by the enzyme CYP3A4. Selective inhibitor CYP3A4 ketoconazole increases AUC by 107%, and rifampicin reduces it by 88%. Although specific interactions have not been studied, it can be assumed that protease inhibitors such as ritonavir and saquinavir, as well as CYP3A4 inhibitors such as erythromycin and Itraconazole, increase the activity of Buy Tadalafil Canada. The simultaneous administration of antacid (magnesium hydroxide/aluminium hydroxide) and Tadalafil Eli Lilly reduced the rate of absorption of the latter without changing the AUC. Tadalafil Generic Cialis 20mg enhances the hypotensive effect of nitrates. This is due to the additive effect of nitrates and Tadalafil Usa on the metabolism of nitric oxide and cGMP. Therefore, the use of Cialis Tadalafil 20 Mg Tablets in patients receiving nitrates is contraindicated
