24 June 2014, San Francisco, California, USA, (http://buykamageragold.com/) : Viagra is the trade name for a drug called Sildenafil. It is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5) inhibitors. Viagra and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by increasing the erectile response when a man is sexually stimulated.

Action:

Viagra does not cause a man to be sexually aroused. It is only effective if you are sexually aroused. To understand how it works you need to understand the mechanics of how a man gets an erection. When you get sexually stimulated, the nervous system in the erectile tissue of your penis releases nitric oxide (NO). The nitric oxide stimulates an enzyme that produces something called a messenger cyclic guanosine monophosphate (cGMP). The cGMP relaxes the smooth muscle cells. One result of this is that the arteries in your penis dilate and the blood can flow into your penis more easily. Another result is that the erectile tissue itself fills with blood. Both of these process result in an erection. This pill works by maintaining the level of cGMP in the smooth muscle cells. If you are not turned on, your brain will not stimulate the release of any nitric oxide and you will not produce any cGMP.

Interaction:

Viagra interacts with many drugs. It is important to inform the doctor of all prescription and non-prescription medication taken, especially:

• nitrate medications (e.g. glyceryl trinitrate (GTN), nitroglycerin, isosorbide mononitrate or dinitrate)
• nitroprusside
• cimetidine
• erythromycin
• azole antifungals (e.g., itraconazole, ketoconazole)
• mibefradil
• rifamycins (e.g., rifampicin)
• Alpha blockers, prescribed for prostate disease or high blood pressure
• Ritonavir o Amyl, Butyl or Isopropyl nitrates ("Poppers")

SIDE EFFECTS:

Approximately 15% of persons taking sildenafil experience side effects. The most common side effects are facial flushing (1 in 10),headaches (1 in 6), stomach pain, nasal congestion, nausea, diarrhea, and an inability to differentiate between the colors green and blue. Rare cases of sudden loss of hearing have been reported with phosphodiesterase inhibitors such as sildenafil, sometimes with ringing in the ears anddizziness. If changes in hearing occur, patients should discontinue their sildenafil and seek immediate medical attention.

Dosage:

This product is available in three dosages: 25mg, 50mg and 100mg. Some men may respond to a lower dose of it. Some men may already be taking medicines that interact with it and thus need to adjust the Viagra dosage they are taking.
