Let’s start with Viagra, the first licensed medication for erectile dysfunction treatment.

Viagra

Viagra is the most popular of the three prescription medications for impotence treatment. It is manufactured by Pfizer and it first hit the market in 1998. Being a PDE-5 inhibitor drug, it blocks the action of PDE-5 enzyme to increase the flow of blood to the penis. As the blood enters the penis, the cavernosa chambers in the penis expand and produce an erection. Viagra should be taken 30 minutes before sex and its effects usually last for four to five hours. The available strengths of Viagra are 25mg, 50mg, and 100mg.

Apart from treating erectile dysfunction, Viagra is also known to help in treating and controlling certain other health condition also. Raynaud’s syndrome is a condition in which extremities become pale and cold due to insufficient supply of blood when exposed to cold temperature. Sildenafil Citrate, the active ingredient in Viagra, can help in free flow of blood to the extremities to treat this condition. This impotence pill can also help people who are suffering from stroke, as it improves neurological functions and speeds up recovery time.

Cialis

Cialis is also a prescription medication for the treatment of erectile problems. It entered the market 5 years after Viagra. Cialis is manufactured by Eli Lilly and ICOS. The mechanism of action of Cialis is similar to that of Viagra. Cialis provides a long-lasting effectiveness for up to 36 hours. It means that one dose of this medication can give you a 36-hour window in which you can get and maintain erections when you are sexually aroused. Tadalafil is the active ingredient in Cialis. Another dosage form of this impotence pill is Cialis daily or Cialis once a day which you need to take at the same time each day to treat erection problems. Cialis as needed is available in strengths of 10mg and 20mg, whereas once-a-day Cialis is available in strengths of 2.5mg and 5mg.

Levitra

Levitra is another prescription-only medication for the treatment of impotence. Levitra is manufactured by Bayer. It is the third medication in the list to enter the market after Viagra and Cialis. Levitra also belongs to a class of drugs called PDE-5 inhibitors. It can be taken 30-60 minutes before sex and its effects can last for about four to five hours. The recommended starting dose for Levitra is 10mg. The other available doses are 5mg and 20mg. Vardenafil, the active ingredient in Levitra, can block the action of PDE-5 enzyme to restore the level of cGMP (a chemical that helps in dilation of the arteries in the pens) to produce an erection. This impotence pill also works for men who have underlying conditions such as high blood pressure, high cholesterol, and diabetes.

PDE-5 inhibitors should only be taken after consulting a doctor. Based on an individual’s response and tolerance to a particular medication, Viagra, Levitra, or Cialis is prescribed by a doctor to treat erectile dysfunction. The working mechanism of these three medications is same with some slight differences that separate one from the other.
