Viagra Professional General Information
Viagra Professional is an innovative medicine that is used effectively against impotence and also possesses a few properties of an enhancer. This medicine provides a powerful erection, and it can be taken 15-30 minutes before sexual intercourse. Although it has proven effective and safe, it is still a prescription medicine, and it is not intended for everyone. This medicine is not meant for women and children. Doctors do not usually recommend it for people over 65.
Viagra Professional should be taken orally. It works for 8 hours after administration. It should be taken once every day, never more. Like many other vasolidators, sildenafil may cause your blood pressure to lower a little. However, if you use the drug together with other medicines (nitrates, alpha-blockers, antiviral medications), this may cause your blood pressure to fall dramatically and result in serious side effects. Sildenafil is absolutely incompatible with nitroglycerin and other nitrates!
This drug is available in blue tablets, which contain 25, 50 or 100 mg of sildenafil. Your doctor should help you choose the most appropriate dose for you. If you are going to use Viagra professional in the foreseeable future, please, discuss with your doctor your health problems, if any, you have or had before and medicines you are taking or have taken recently. If you have any chronic diseases, you will have to pass a thorough test in order to make sure the drug will not bring on complications.
Your healthcare provider may not recommend you to take Viagra professional if you have underlying cardiac disorders, especially if you are using nitrates. Concomitant use of Viagra with nitric drugs can be extremely harmful or fatal. Do not use sildenafil if you have low blood pressure, because this may impair blood supply to vital organs. The drug is contraindicated to people suffering stenosis, because it may hamper blood flow to the heart and cause ischemia and death.
Sildenafil works by blocking phosphodiestrase type 5 (PDE5), an enzyme, which strains the smooth penile muscle and restricts blood flow to the penis. Besides, sildenafil stimulates the synthesis of cyclic guanine monophosphate (cGMP), which relaxes the smooth muscle and facilitates blood flow to the penile chambers, thus enhancing erection. What's most interesting about sildenafil is its selective action. Indeed, it is just because it exerts greater influence on PDE5 than on any other enzyme. Viagra Professional is purely a stimulating drug, and it does not cure causes of impotence, which, to mention a few, include cardiac disorders, diabetes, hypoglycemia, stress, hypotension, etc. Many of these conditions require cautious use of Viagra Professional; therefore, the medicine should not be used without a doctor's supervision.
