In addition to Viagra, which was the Pfizer breakthrough for the treatment of erectile dysfunction, three other drug companies Abbot Laboratories, Eli-Lilly and Bayer, have produced treatments for men’s impotence problems.

Uprima (Abbot Laboratories) is a substance which contains apomorphine a drug which is associated with neurological problems. Unlike Viagra which relaxes the blood vessels in the penis, Uprima enhances libido by acting on sensors in the brain to stimulate sexual arousal. Uprima is a faster acting product and is absorbed under the tongue, therefore passing into the bloodstream quickly. It can be helpful if you have difficulty swallowing medicines in tablet form.

Cialis (Eli-Lilly) is a treatment for men which inhibit an enzyme found in erectile tissue, promoting vascular and muscular changes that produce an erection. The product works in similar way to Viagra, but it is claimed to be both faster acting and effective for 24 hours or more. The same precautions apply to Cialis as Viagra and indeed any prescribed medicine.

Levitra (Bayer) again works to alleviate erectile dysfunction in a similar way to Viagra and Cialis. There are three potential doses of Levitra: 5mg. 10mg and 20mg. The doses may have to be adjusted by your doctor should the initial dose not have the desired effect.

All medicines should be treated with respect and no treatment for impotence problems should be taken in conjunction with any other medication. If you unsure, or have any doubt consult your pharmacist or doctor.
