Nitrates dilate (open up) blood vessels around the heart and are used in conditions such as angina and coronary artery disease. Combining Cialis, or any other pill for erectile dysfunction, with a nitrate could cause a massive and potentially fatal drop in blood pressure. Recreational drugs such as amyl or butyl nitrate may also have this effect when mixed with Cialis. CIALIS, when taken once daily, was shown to be effective in improving erectile function in men with erectile dysfunction (ED). The effects of tadalafil on cardiac function, hemodynamics, and exercise tolerance were investigated in a single clinical pharmacology study. In this blinded crossover trial, 23 subjects with stable coronary artery disease and evidence of exercise-induced cardiac ischemia were enrolled.
Studies in vitro have demonstrated that tadalafil is a selective inhibitor of PDE5. PDE5 is found in platelets.When administered in combination with aspirin, tadalafil 20 mg did not prolong bleeding time, relative toaspirin alone. CIALIS has not been administered to patients with bleeding disorders or significant active peptic ulceration. PDE5inhibitors, including CIALIS, and alpha-adrenergic blocking agents are both vasodilators with blood-pressure-lowering effects. [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS, and CLINICAL PHARMACOLOGY] .
The breakdown and elimination of tadalafil from the body may be decreased by erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), indinavir (Crixivan) and ritonavir (Norvir). Therefore, these drugs may increase the levels of tadalafil in the blood. If you’re using once-daily Cialis for either erectile dysfunction (ED) or benign prostatic hyperplasia (BPH), take your dose around the same time each day. This helps keep a consistent amount of the drug in your body to provide the maximum effect. If you forget to take doses, skip doses, or take doses late, the medication won’t work as well. Cialis contains the active ingredient tadalafil, which is part of the medication group known as phosphodiesterase-5 inhibitors.
Do not take Cialis if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as "poppers". Taking tadalafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. To treat erectile dysfunction (ED), your doctor may have you take Cialis only as needed before sexual activity.
The cost of the medicine is in addition to the prescription fee. When medicines are supplied online an electronic private prescription from a doctor is usually involved and costs are usually quite a lot lower. Generic Cialis (tadalafil) is available on the NHS but there are limits on the amount which can be prescribed, usually 1 dose per week - NHS prescription fees apply.
