Viagra vs Cialis

Medications for erectile dysfunction are now widely available but sometimes confusions comes in to some patients as viagra versus cialisto what is a better drug that would solve their ED problem. Many compare Viagra vs Cialis with regards to its potency and effectiveness. Some doctors may also have their own preferences in prescribing ED medications so it is better to get more information about these two drugs before buying one.

Viagra and Cialis are both PDE5 inhibitors. Their main function is to maximize the flow of blood in the arteries connected to the penis. And with greater flow of blood, the greater the erection will be. Erectile dysfunction happens when there is deficiency of enzyme in the penis that would increase the blood flow. Both drugs are FDA approved. Though Viagra was introduced in the market earlier than Cialis and another competitor Levitra, these three were now competing in the same field of medication.

Now let us discuss more details on Cialis. Tadalafil is the generic name of Cialis and was developed by the biotechnology company ICOS. It was later marketed by Eli Lilly when they acquired the ICOS company. The FDA approved the drug in the US in November 2003 trailing the more popular ED drug Viagra and Levitra. In May 2009, the drug was also approved as an effective treatment for pulmonary arterial hypertension. The chemical composition of Cialis is different from viagra but both drugs works well in treating ED.

Dosage Comparison

Cialis comes in tablet form with dosages of 5 mg, 10 mg, and 20 mg. If it is used as a treatment for pulmonary arterial hypertension, the recommended dosage is 40 mg (two 20-mg tablets) once daily. The tablets are yellow, film-coated, and almond-shaped. Viagra on the other hand are available in 25 mg, 50 mg, and 100 mg tablets.

The normal dosage for Cialis is 10 mg while Viagra is 50 mg. Tadalafil can be taken 30 minutes to 12 hours before a sexual activity while its soft tabs can be taken 15 minutes prior to sexual intercourse. The effect of Cialis is longer as compared to Viagra which only last up to 4 hours. Some patients can feel the effects of Cialis up to 36-hour after ingestion and because of its longer effects many calls it "The Weekend Pill."

Negative side effects may be felt if it is taken beyond the prescribe dosage. Once side effects are noted, immediately discontinue taking Cialis and consult a health care provider. There are cases where these drugs can cause an erection for more than 4 hours or result to a painful erection. This is a major concern that must be addressed immediately by a doctor to prevent damage to the penile tissues.

Cialis should not be taken in combination with low blood pressure medication as this can potentially cause a heart attack. Please tell your doctor if you are taking some of these medications; antibiotics, anti depressants, anti-fungal, heart or blood pressure medicines, and HIV medicines. Tadalafil can counteract the effects of these drugs. Normally these side effects whether mild or serious should go away after the drug is eliminated from the body or the patient discontinued its use.
