Pharmacokinetics
The pharmacokinetics of Cialis Tadalafil Tablets in patients with erectile dysfunction is similar to the pharmacokinetics of Buy Tadalafil Canada in persons without erectile dysfunction. Absorption After taking Tadalafil Tablets Usp 20 Mg 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 Citrate Dosage does not depend on the meal, so Buy Tadalafil Canada 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 Dosage 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. 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 10mg Tablets 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 Cheap Generic Tadalafil 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 Cheap Generic Tadalafil. Therefore, the concentration of this metabolite is not clinically significant. Excretion In healthy individuals, the average clearance of Cialis Tadalafil 20 Mg Tablets when administered is 2.5 l/h, and the average T1/2 - 17.5 h. Buy Tadalafil Canada 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 5mg India 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 Tablets (AUC), patients with severe renal insufficiency are not recommended to use Cialis Tadalafil Tablets. The pharmacokinetics of Tadalafil Cialis From India 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. When prescribing Cialis Tadalafil 20 Mg Tablets to patients with severe liver failure, it is necessary to pre-assess the risk and benefit of using Tadalafil Cialis From India. In patients with diabetes mellitus during the use of Cialis Tadalafil Tablets AUC was less by about 19% than in healthy individuals. This difference does not require dose selection.

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 Cialis Tadalafil Buy Online 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 10mg Dosage 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 40 Mg Dosage in lower doses. Treatment: in case of overdose, standard symptomatic treatment is necessary. In hemodialysis Tadalafil Tablets India practically displayed.
Interaction with other drugs
Cialis Tadalafil 10mg Tablets 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 Cheap Generic Tadalafil. The simultaneous administration of antacid (magnesium hydroxide/aluminium hydroxide) and Tadalafil 40 Mg Dosage reduced the rate of absorption of the latter without changing the AUC. Tadalafil Cialis From India enhances the hypotensive effect of nitrates. This is due to the additive effect of nitrates and Tadalafil For Erectile Dysfunction on the metabolism of nitric oxide and cGMP. Therefore, the use of Tadalafil 40 Mg Dosage in patients receiving nitrates is contraindicated
Pharmacological action
Tadalafil 5mg India for the treatment of erectile dysfunction. Buy Tadalafil Canada is a reversible selective inhibitor of cyclic guanosine monophosphate (cGMP) PDE5. When sexual arousal causes local release of nitric oxide, inhibition of PDE5 by Tadalafil For Erectile Dysfunction 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. Tadalafil 10mg Dosage has no effect in the absence of sexual arousal.
In vitro studies have shown that Tadalafil Cialis From India is a selective PDE5 inhibitor. PDE5 is an enzyme found in the smooth muscles of the cavernous body, in the smooth muscles of the vessels of the internal organs, in skeletal muscles, platelets, kidneys, lungs and cerebellum. The effect of Buy Cialis Tadalafil on PDE5 is more active than on other PDES. Cialis Tadalafil 20 Mg Tablets is 10,000 times more potent against PDE5 than against PDE1, PDE2, PDE4 and PDE7, which are localized in the heart, brain, blood vessels, liver, leukocytes, skeletal muscles and other organs. Tadalafil Tablets Usp 20 Mg is 10,000 times more active in blocking PDE5 than PDE3, an enzyme that is found in the heart and blood vessels. This selectivity concerning PDE5 compared to ФДЭ3 is important because ФДЭ3 is an enzyme participating in the reduction of cardiac muscle. In addition, Tadalafil Cialis From India is approximately 700 times more active against PDE5 than against PDE6 found in the retina and responsible for photo transmission. Tadalafil Usa is also showing the action in 9000 times more potent against PDE5 compared to its effect on PDE8, PDE9 and PDE10, and 14 times more potent against PDE5 compared to PDE11. Tissue distribution and physiological effects of inhibition of PDE8 - PDE11 have not yet been clarified.
Tadalafil Tablets Usp 20 Mg improves erection and increases the possibility of a full sexual intercourse.
Cialis Tadalafil 10mg Tablets in healthy individuals does not cause a significant change in systolic and diastolic pressure in comparison with placebo in the supine position (the average maximum decrease is 1.6/0.8 mm Hg. respectively) and in the standing position (the average maximum decrease is 0.2/4.6 mm Hg. art., respectively). Tadalafil 5mg India does not cause a significant change in heart rate. Tadalafil 5mg India does not cause changes in color recognition (blue/green), due to its low affinity for PDE6. In addition, there is no effect of Tadalafil Eli Lilly on visual acuity, electroretinogram, intraocular pressure and pupil size.
Several studies have been conducted to assess the effect of daily Tadalafil 5mg India on spermatogenesis. None of the studies showed an undesirable effect on the morphology of sperm and their mobility. One study found a decrease in the average sperm concentration compared to placebo. A decrease in sperm concentration was associated with a higher ejaculation rate. In addition, there was no undesirable effect on the average concentration of sex hormones, testosterone, LH and FSH when taking Buy Cialis Tadalafil compared to placebo.
The efficacy and safety of Buy Tadalafil Canada (at doses of 2.5 mg and 5 mg) was studied in clinical trials. There was an improvement in erection in patients with erectile dysfunction of all degrees of severity when taking Cialis Tadalafil Buy Online 1 time/day. In studies of the primary efficacy of Tadalafil Eli Lilly at a dose of 5 mg, 62% and 69% of sexual intercourse attempts were successful compared to 34% and 39% of placebo patients. Tadalafil 10mg Dosage at a dose of 5 mg significantly improved erectile function for 24 hours between doses.
Tadalafil Citrate Dosage is mainly metabolized with the participation of the CYP3A4 isoenzyme. Selective inhibitor of CYP3A4, ketoconazole (400 mg/day) increases the AUC of Tadalafil 10mg Dosage in a single dose by 312% and SMACNA 22%, and ketoconazole (200 mg/day) increases the AUC of Tadalafil For Erectile Dysfunction in a single dose by 107% and Smachna 15% relative to the AUC values for Tadalafil Tablets Usp 20 Mg Smartelco one. Ritonavir (200 mg 2 times a day), an inhibitor of isoenzymes CYP3A4, 2C9, 2C19 and 2D6, increases the AUC of Cialis Tadalafil Buy Online in a single dose by 124% without changing Cmax. Although no specific interactions have been studied, it can be assumed that other HIV protease inhibitors such as saquinavir and CYP3A4 isoenzyme inhibitors such as erythromycin and Itraconazole increase Tadalafil For Erectile Dysfunction activity.
Selective inducer of CYP3A4, rifampin (600 mg/day), reduces the exposure of a single dose of Tadalafil Generic Cialis 20mg (AUC) by 88% and SMACNA 46% relative to the AUC values for Tadalafil 40 Mg Dosage Smartelco one. It can be assumed that the simultaneous use of other inducers of CYP3A4 isoenzyme should also reduce the concentration of Tadalafil Tablets India in plasma.
Simultaneous administration of antacid (magnesium hydroxide/aluminum hydroxide) and Tadalafil Usa reduces the rate of absorption of Tadalafil Usa without changing the area under the pharmacokinetic curve for Cialis Tadalafil Tablets. The increase in gastric pH as a result of the H2-histamine receptor blocker nizatidine had no effect on the pharmacokinetics of Tadalafil For Erectile Dysfunction.
The safety and effectiveness of the combination of Tadalafil Generic Cialis 20mg with other types of treatment of erection disorders have not been studied, so the use of such combinations is not recommended.
