From the graph it appears that high concentrations of tadalafil occurs from 1hr to 6hr after ingestion. This is the time when you get the maximum help. Sure, it does give you a 36hr window according to clinical studies, but the concentration of the medicine is highest from hours — so why not put that to use. The peak level is around and occurs at around the 2hour mark and it becomes about around How it works Cialis is a brand trade name for tadalafil.
This enzyme breaks down cGMP, a substance that induces smooth muscles to relax. Blocking PDE-5 means increased levels of cGMP within the smooth muscles which promotes muscle relaxation and vasodilation a widening of blood vessels. High levels of PDE-5 are found in the penis, lungs, and retina. PDE-5 is also found throughout the body within the smooth muscle cells of blood vessels and muscles.

For the full list of restrictions, see the package leaflet. Why has Cialis been approved? What measures are being taken to ensure the safe and effective use of Cialis?
A risk management plan has been developed to ensure that Cialis is used as safely as possible. PDE5 inhibitors, including Cialis, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated.
Clinical pharmacology studies have been conducted with coadministration of tadalafil with doxazosin, tamsulosin or alfuzosin. Antihypertensives — PDE5 inhibitors, including tadalafil, are mild systemic vasodilators.
Clinical pharmacology studies were conducted to assess the effect of tadalafil on the potentiation of the blood-pressure-lowering effects of selected antihypertensive medications amlodipine, angiotensin II receptor blockers, bendrofluazide, enalapril, and metoprolol. Small reductions in blood pressure occurred following coadministration of tadalafil with these agents compared with placebo. Alcohol — Both alcohol and tadalafil, a PDE5 inhibitor, act as mild vasodilators. When mild vasodilators are taken in combination, blood-pressure-lowering effects of each individual compound may be increased.
Substantial consumption of alcohol e. Tadalafil did not affect alcohol plasma concentrations and alcohol did not affect tadalafil plasma concentrations. H2 Antagonists e. Nizatidine — An increase in gastric pH resulting from administration of nizatidine had no significant effect on pharmacokinetics. Studies have shown that drugs that inhibit CYP3A4 can increase tadalafil exposure.
CYP3A4 e. Although specific interactions have not been studied, other CYP3A4 inhibitors, such as erythromycin, itraconazole, and grapefruit juice, would likely increase tadalafil exposure. Although specific interactions have not been studied, other HIV protease inhibitors would likely increase tadalafil exposure [see Dosage and Administration 2. Although specific interactions have not been studied, other CYP3A4 inducers, such as carbamazepine, phenytoin, and phenobarbital, would likely decrease tadalafil exposure.
No dose adjustment is warranted. The reduced exposure of tadalafil with the coadministration of rifampin or other CYP3A4 inducers can be anticipated to decrease the efficacy of Cialis for once daily use; the magnitude of decreased efficacy is unknown. Potential for Cialis to Affect Other Drugs Aspirin — Tadalafil did not potentiate the increase in bleeding time caused by aspirin. Cytochrome P Substrates — Cialis is not expected to cause clinically significant inhibition or induction of the clearance of drugs metabolized by cytochrome P CYP isoforms.
CYP1A2 e. Theophylline — Tadalafil had no significant effect on the pharmacokinetics of theophylline. When tadalafil was administered to subjects taking theophylline, a small augmentation 3 beats per minute of the increase in heart rate associated with theophylline was observed.
CYP2C9 e. Warfarin — Tadalafil had no significant effect on exposure AUC to S-warfarin or R-warfarin, nor did tadalafil affect changes in prothrombin time induced by warfarin. Midazolam or Lovastatin — Tadalafil had no significant effect on exposure AUC to midazolam or lovastatin.
P-glycoprotein e. Digoxin — Coadministration of tadalafil 40 mg once per day for 10 days did not have a significant effect on the steady-state pharmacokinetics of digoxin 0. There are no data with the use of Cialis in pregnant women to inform any drug-associated risks for adverse developmental outcomes. Surviving offspring had normal development and reproductive performance.
Lactation Risk Summary Cialis is not indicated for use in females. Females and Males of Reproductive Potential Infertility Based on the data from 3 studies in adult males, tadalafil decreased sperm concentrations in the study of 10 mg tadalafil for 6 months and the study of 20 mg tadalafil for 9 months. This effect was not seen in the study of 20 mg tadalafil taken for 6 months. There was no adverse effect of tadalafil 10 mg or 20 mg on mean concentrations of testosterone, luteinizing hormone or follicle stimulating hormone.
The clinical significance of the decreased sperm concentrations in the two studies is unknown. There have been no studies evaluating the effect of tadalafil on fertility in men [see Clinical Pharmacology Based on studies in animals, a decrease in spermatogenesis was observed in dogs, but not in rats [see Nonclinical Toxicology Tell your doctor if you are breast-feeding.
