And becauseCialis operates in conjunction with sexual stimulation, select all by herself when the time is right.
Why should you chooseCialis?
Cialis multiplies the time in which the couple can have sex compared with other treatments for erectile dysfunction.Cialis can also be taken with food and alcohol but that the effect worse.
General erectile function
81% reported improved erection ability regardless of the severity ofCialis 20 mg.
Successful intercourse attempts
75% reported successful intercourse attempts withCialis 20 mg.
Freedom of choice withCialis
The man works sexually for a long time is a great advantage to the couple through the planning and the time pressure is reduced. It gives more freedom in the relationship and allow for more spontaneity – together you can choose the right moment when the desire to appear.Cialis be taken if necessary – before the weekend, vacation or simply when you want and then can man sexual function up to 36 hours after tablet intake.
Choosing the right dose
Adult men
The recommended dose ofCIALIS is 10 mg, taken prior to anticipated sexual activity.CIALIS can be taken independently of meals. In those patients in which 10 mg Tadalafil does not provide sufficient power can be 20 mg tested. It can be taken until 30 minutes before sexual activity. Not more than one dose per day should be taken.
The safety of continuous daily use for a long time has not been established. Therefore advised against this from day to day use of the drug but also because of the effect of Tadalafil usually persists longer than a day.
Elderly men
Dose adjustment is not necessary for elderly patients.
Men with impaired renal function
Dose adjustment is not necessary for patients with mild to moderate renal impairment. For patients with severe renal impairment, a maximum dose of 10 mg.
Men with impaired liver function
The recommended dose is 10 mg. The dose is taken before anticipated sexual activity and may be taken independently of meals. Clinical safety data for patients with severe hepatic impairment (Child-Pugh Class C) is limited. If prescribed, a careful individual benefit / risk assessment of the prescribing physician. There are no available data on intake of higher doses than 10 mg Tadalafil for patients with hepatic impairment.
Men with diabetes
Dose adjustment is not necessary for patients with diabetes.
Children and Youth
CIALIS should not be used by persons below 18 years.
Pharmacological properties
Pharmacodynamic properties
Tadalafil is a selective, reversible inhibitor of cyclic guanosinmonofosfat (cGMP)-specific fosfodiesteras-5 (PDE5). When the sexual activity releases nitric oxide locally, Tadalafil inhibits PDE5, which results in increased levels of cGMP in the corpus cavernosum. This gives the relaxation of smooth muscle and inflow of blood to the penis, which produces an erection. Tadalafil has no effect without sexual stimulation.
Three clinical studies were conducted with 1054 residents present patients to determine the time period during whichCIALIS appears.CIALIS showed statistically significant improvement in erectile function and ability to a satisfactory sexual intercourse up to 36 hours after dosintag. Also shown improvement in patients’ ability to achieve and maintain an erection for successful sexual intercourse, compared with placebo, as early as 16 minutes after dosintag.
Tadalafil has been studied in 16 clinical studies with a total of 3 250 patients, in doses from 2 to 100 mg. In these studies included patients with erectile dysfunction of varying severity (mild, moderate, severe), different etiology, age (21-86 years) and ethnic group. Most patients had erectile dysfunction for at least 1 years. In the primary efficacy studies of general patient reported 81% toCIALIS improved erection compared to 35% for those receiving placebo. Patients with erectile dysfunction in all severity classes also reported improved erection after takingCIALIS (86%, 83% and 72% for mild, moderate and severe, compared with 45%, 42% and 19% with placebo). In the primary efficacy studies, 75% of attempts at sexual intercourse successful in patients treated withCIALIS, Compared with 32% for those treated with placebo.
Pharmacokinetic data
Absorption
Tadalafil is rapidly absorbed after oral administration and maximum plasma concentration (mean) (Cmax) achieved after a mediantid at 2 hours after ingestion. Absolute bioavailability of Tadalafil after oral dosing has not been established.
The speed and extent of absorption of Tadalafil is not affected by food.CIALIS can thus be taken independently of meals. The timing of dosintag (morning or evening) had no clinically relevant effect on the speed or degree of absorption.
Distribution
Distribution volume is approximately 63 l (mean), suggesting that Tadalafil is distributed to the tissues. At therapeutic concentrations are 94% bound to protein in plasma. Protein binding is not affected by impaired renal function.
Less than 0.0005% of the intake dose is found in semen in healthy volunteers.
Metabolism
Tadalafil is metabolized predominantly by cytochrome P450 (CYP) 3A4 isoforms. The main metabolite in the circulation is metylkatekolglukuronid. This metabolite is at least 13 000 times less potent than Tadalafil for PDE5. Consequently, it is not to be clinically active at observed metabolitkoncentration.
Elimination
The mean oral clearance of Tadalafil is 2.5 l / hour and mean half-life is 17.5 hours for healthy volunteers. Tadalafil is excreted predominantly as inactive metabolites, mainly in feces (about 61% of dose) and to a lesser extent in the urine (approximately 36% of the dose).
Linearity / non-linearity
The pharmacokinetics of Tadalafil is linear with regard to time and dose. In the dose range 2.5 to 20 mg AUC increases proportionally with dose. Plasma concentrations reach steady-state within 5 days at the dose once daily.
Pharmacokinetics, which is determined on a population of patients with erectile dysfunction, is similar to that seen in subjects without erectile dysfunction.
Warnings and precautions
Before pharmacological treatment is started, the included a history and the patient to undergo a physical examination to ensure the diagnosis of erectile dysfunction and to investigate potential underlying causes.
Before the treatment of erectile dysfunction operation, the physician should assess the patient’s cardiovascular status, because there is a certain risk of cardiac distress during sexual activity. Tadalafil has vasodilatory properties, which gives a light and transient blood pressure cases, which may enhance the hypotensiva effect of nitrates.
Side effects
The most common side effects are headache and dyspepsia, see tables.

The side effects reported with Tadalafil has been transient and generally mild or moderate.
There is only limited adverse reaction data for patients over 75 years.
At follow-up after the approval has been extended erection and priapism reported very rare.
Studies
Interaction studies have been performed with 10 mg and / or 20 mg Tadalafil, as illustrated by the following. For those studies where only a tadalafildos of 10 mg was used, may be clinically relevant interactions at higher doses is not completely excluded.
Effects of other drugs on Tadalafil
Tadalafil is metabolized primarily by CYP3A4. A selective inhibitor of CYP3A4, ketoconazole (200 mg daily), gave a 2-fold increase in AUC for Tadalafil (10 mg) and an increase in Cmax by 15% compared with the AUC and Cmax for only Tadalafil. Ketoconazole (400 mg daily) gave a 4-fold increase in AUC for Tadalafil (20 mg) and an increase in Cmax of 22%. Ritonavir (200 mg twice daily), a protease inhibitor which inhibits CYP3A4, CYP2C9, CYP2C19 and CYP2D6, resulted in a 2-fold increase in AUC for Tadalafil (20 mg) and unchanged Cmax. Specific interactions have not been studied but the concomitant administration of other protease inhibitors, such as saquinavir, and other CYP3A4 inhibitors, such as erythromycin, clarithromycin, itraconazole and grapefruit juice, should be done with caution as one would expect increased plasma concentration of Tadalafil.
Effects of Tadalafil and organic nitrates
Clinical studies show that Tadalafil (10 mg and 20 mg) reinforces the hypotensiva effect of nitrates. It isCIALIS contraindicated in patients who use any form of organic nitrates.
