Clinical pharmacology
Cialis Tadalafil Tablets is a reversible selective inhibitor of specific PDE-5 cGMP. When sexual arousal causes local release of nitric oxide, inhibition of PDE-5 by Cialis Tadalafil 20 Mg Tablets 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.

Tadalafil Citrate Dosage is 10,000 times more active in blocking PDE-5 than PDE-3, an enzyme that is found in the heart and blood vessels. This selectivity for PDE-5 versus PDE-3 is important because PDE-3 is an enzyme involved in cardiac muscle contraction. In addition, Tadalafil 5mg India is approximately 700 times more active against PDE-5 than against PDE-6, which is found in the retina and is responsible for photo transmission. Tadalafil Cialis From India is also showing the action in 9000 times more potent against PDE-5 compared with its effect on PDE-8, PDE-9, PDE-10 and 14 times more potent against PDE-5 compared to PDE-11.

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.

Interaction with other drugs
Tadalafil Dosage For Erectile Dysfunction 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 Cialis Tadalafil Tablets. The simultaneous administration of antacid (magnesium hydroxide/aluminium hydroxide) and Cialis Tadalafil 20 Mg Tablets reduced the rate of absorption of the latter without changing the AUC. Tadalafil 10mg Dosage enhances the hypotensive effect of nitrates. This is due to the additive effect of nitrates and Cialis Tadalafil 10mg Tablets on the metabolism of nitric oxide and cGMP. Therefore, the use of Tadalafil 5mg India in patients receiving nitrates is contraindicated

Relaxation of the smooth muscles of the vessels leads to an increase in blood perfusion in these organs and as a consequence — to reduce the severity of symptoms of BPH. Relaxation of the smooth muscles of the prostate and bladder can further enhance vascular effects.

Pharmacokinetics
The pharmacokinetics of Tadalafil Generic Cialis 20mg in patients with erectile dysfunction is similar to the pharmacokinetics of Buy Cialis Tadalafil in persons without erectile dysfunction. Absorption After taking Buy Cialis Tadalafil inside Tadalafil Generic Cialis 20mg 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 Tadalafil Dosage For Erectile Dysfunction 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. The distribution of Css in plasma is achieved within 5 days when taking Buy Cialis Tadalafil 1 time/day. The average Vd is about 63 liters, which indicates that Cheap Generic Tadalafil is distributed in the tissues of the body. The plasma protein binding of Tadalafil For Erectile Dysfunction at therapeutic concentrations 94%. In healthy individuals, less than 0.0005% of the administered dose was found in sperm. Metabolism Cialis Tadalafil 20 Mg Tablets 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 Tadalafil Generic Cialis 20mg when administered is 2.5 l/h, and the average T1/2 - 17.5 h. Tadalafil Cialis From 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).

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 renal insufficiency of mild to moderate severity dose adjustment is not required.
