1.Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Cialis and nitrates both lower blood pressure. Taking them together can cause a significant and potentially life-threatening drop in blood pressure (hypotension), leading to dizziness, fainting, or even heart attack or stroke. It is contraindicated to use Cialis with nitrates or recreational "poppers" (amyl nitrites).
2.Alpha-blockers (e.g., prazosin, terazosin, tamsulosin): Both Cialis and alpha-blockers relax blood vessels, which can lead to excessive blood pressure reduction when used together. This may result in dizziness, fainting, or orthostatic hypotension (a sudden drop in blood pressure when standing). If needed, your doctor may adjust the dosage or recommend spacing the medications.
3.Other antihypertensive drugs (e.g., atenolol, propranolol, enalapril, lisinopril): Cialis can enhance the blood-pressure-lowering effects of these medications. While this interaction is usually less severe than with nitrates or alpha-blockers, it can still cause dizziness or fainting in sensitive individuals. Close monitoring of blood pressure is recommended.
Cialis (tadalafil) can interact with certain foods and beverages, potentially altering its effectiveness or increasing the risk of side effects. Here are the key drug-food interactions to be aware of:
Cialis has been the go-to treatment for erectile dysfunction since it became available in 1998, the FDA said Wednesday.
A major problem for Cialis, which is marketed by Eli Lilly, is the long-lasting effects of it on the blood vessels in the penis, which can lead to a variety of side effects, including erectile dysfunction.
“The active ingredient in Cialis is tadalafil,” the FDA said in a written statement.
Tadalafil is also known as the active ingredient in Viagra, Cialis and Levitra.
The drug has been on the market since it was launched by Eli Lilly in the US in 1998.
The U. S. Food and Drug Administration has found that it could be used for some other medical conditions but is not currently approved for that.
Cialis will start selling in the United States in the third quarter of 2007 and is expected to cost about $90 for a 30-tablet bottle. The average retail price of Viagra, Cialis and Levitra is about $30 in the United States and about $30 in Canada, according to a statement from the pharmaceutical company.
Cialis, which has a patent for about a decade, is approved for use in the European Union and in China, and it is also being sold in other countries. The drug was approved for marketing in the US in 1998 and is also approved for marketing in Europe and in the Middle East.
Food and Drug Administration says that it has not yet found an approved treatment for erectile dysfunction in patients who take the drug, but that it has determined that it is effective.
“The FDA’s approval of Cialis for the treatment of erectile dysfunction will not increase its prevalence or cure the condition,” the FDA said in a statement.
The drug is known by its generic name tadalafil and is sold by many different manufacturers, including Cialis and Levitra. Other manufacturers include Eli Lilly and Pfizer.
In the United States, it is sold as Cialis, which is available in the pharmacy, but is not currently FDA-approved for the treatment of erectile dysfunction. The Food and Drug Administration has not approved Cialis for this use.
Cialis is also approved in Europe for a number of other uses, including for the treatment of high blood pressure and to treat benign prostatic hyperplasia.
Food and Drug Administration also is investigating whether the drug can be used as a treatment for enlarged prostates.
“The FDA’s recent approval of Cialis to treat benign prostatic hyperplasia in patients with enlarged prostates is a significant step in the ongoing search for effective treatments for this disease,” the agency said in a statement.
