Patients with severe liver problems or kidney problems should not take more than 10 mg in one dose. Once-a-day dosing is not recommended in patients with severe kidney problems, and should only be prescribed to patients with liver problems after a careful evaluation of the benefits and risks of taking the medicine. How does Cialis work? The active substance of Cialis, tadalafil, belongs to a group of medicines called 'phosphodiesterase type 5 PDE5 inhibitors'. It works by blocking the phosphodiesterase enzyme, which normally breaks down a substance known as cyclic guanosine monophosphate cGMP.

During normal sexual stimulation, cGMP is produced in the penis, where it causes the muscle in the spongy tissue of the penis the corpora cavernosa to relax, allowing the flow of blood into the corpora, producing the erection.

By blocking the breakdown of cGMP, Cialis restores erectile function. However, sexual stimulation is still needed. By blocking the phosphodiesterase enzyme and preventing the breakdown of cGMP, Cialis also improves the blood flow to, and relaxes the muscles of, the prostate and bladder. This may reduce the problems with the flow of urine which are symptoms of benign prostatic hyperplasia.

How has Cialis been studied? One of these studies contained only diabetic men. Once-a-day dosing of Cialis was studied in three further studies lasting 12 to 24 weeks and involving a total of patients. In all studies, the effects of Cialis were compared with those of placebo a dummy treatment , and the main measure of effectiveness was the ability to get and maintain an erection.

This was recorded in two questionnaires completed at home. Tadalafil 10 mg, except for studies with angiotensin II receptor blockers and amlodipine in which a 20 mg dose was applied had no clinically significant interaction with any of these classes. In another clinical pharmacology study, tadalafil 20 mg was studied in combination with up to 4 classes of antihypertensives.

In subjects taking multiple antihypertensives, the ambulatory-blood-pressure changes appeared to relate to the degree of blood pressure control. In this regard, study subjects whose blood pressure was well controlled, the reduction was minimal and similar to that seen in healthy subjects.

In study subjects whose blood pressure was not controlled, the reduction was greater, although this reduction was not associated with hypotensive symptoms in the majority of subjects. In patients receiving concomitant antihypertensive medicinal products, tadalafil 20 mg may induce a blood pressure decrease, which with the exception of alpha-blockers - see above is, in general, minor and not likely to be clinically relevant.

Analysis of Phase 3 clinical trial data showed no difference in adverse events in patients taking tadalafil with or without antihypertensive medicinal products. However, appropriate clinical advice should be given to patients regarding a possible decrease in blood pressure when they are treated with antihypertensive medicinal products.

Riociguat Preclinical studies showed an additive systemic blood pressure lowering effect when PDE5 inhibitors were combined with riociguat. In clinical studies, riociguat has been shown to augment the hypotensive effects of PDE5 inhibitors. There was no evidence of favourable clinical effect of the combination in the population studied.

Concomitant use of riociguat with PDE5 inhibitors, including tadalafil, is contraindicated see section 4. However, as a formal drug-drug interaction study evaluating the effects of tadalafil and 5-alpha reductase inhibitors 5-ARIs has not been performed, caution should be exercised when tadalafil is co-administered with 5-ARIs.

The only pharmacodynamic effect was a small 3. Although this effect is minor and was of no clinical significance in this study, it should be considered when co-administering these medicinal products. Ethinylestradiol and terbutaline Tadalafil has been demonstrated to produce an increase in the oral bioavailability of ethinylestradiol; a similar increase may be expected with oral administration of terbutaline, although the clinical consequence of this is uncertain.

Alcohol Alcohol concentrations mean maximum blood concentration 0. In addition, no changes in tadalafil concentrations were seen 3 hours after co-administration with alcohol. Alcohol was administered in a manner to maximise the rate of alcohol absorption overnight fast with no food until 2 hours after alcohol.

Tadalafil 20 mg did not augment the mean blood pressure decrease produced by alcohol 0. When tadalafil was administered with lower doses of alcohol 0. The effect of alcohol on cognitive function was not augmented by tadalafil 10 mg.

Cytochrome P metabolised medicinal products Tadalafil is not expected to cause clinically significant inhibition or induction of the clearance of medicinal products metabolised by CYP isoforms. R-warfarin Tadalafil 10 mg and 20 mg had no clinically significant effect on exposure AUC to S-warfarin or R-warfarin CYP2C9 substrate , nor did tadalafil affect changes in prothrombin time induced by warfarin.

Aspirin Tadalafil 10 mg and 20 mg did not potentiate the increase in bleeding time caused by acetylsalicylic acid. Antidiabetic medicinal products Specific interaction studies with antidiabetic medicinal products were not conducted. Pregnancy There are limited data from the use of tadalafil in pregnant women. In subjects with end-stage renal disease on hemodialysis, there was a two-fold increase in Cmax and 2.

Exposure to total methylcatechol unconjugated plus glucuronide was 2- to 4-fold higher in subjects with renal impairment, compared to those with normal renal function. In patients on hemodialysis taking or mg tadalafil, there were no reported cases of back pain. Adverse events were similar to those seen at lower doses.

In cases of overdose, standard supportive measures should be adopted as required. Hemodialysis contributes negligibly to tadalafil elimination. Tadalafil has the empirical formula C22H19N3O4 representing a molecular weight of The structural formula is: It is a crystalline solid that is practically insoluble in water and very slightly soluble in ethanol.

Each tablet contains 2. This response is mediated by the release of nitric oxide NO from nerve terminals and endothelial cells, which stimulates the synthesis of cGMP in smooth muscle cells.

Cyclic GMP causes smooth muscle relaxation and increased blood flow into the corpus cavernosum. Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 by tadalafil has no effect in the absence of sexual stimulation. The effect of PDE5 inhibition on cGMP concentration in the corpus cavernosum and pulmonary arteries is also observed in the smooth muscle of the prostate, the bladder and their vascular supply.

The mechanism for reducing BPH symptoms has not been established. PDE5 is found in the smooth muscle of the corpus cavernosum, prostate, and bladder as well as in vascular and visceral smooth muscle, skeletal muscle, urethra, platelets, kidney, lung, cerebellum, heart, liver, testis, seminal vesicle, and pancreas.

Additionally, tadalafil is fold more potent for PDE5 than for PDE6, which is found in the retina and is responsible for phototransduction. PDE11 is an enzyme found in human prostate, testes, skeletal muscle and in other tissues e.
