Viagra: the would be heart drug that became man’s best friend

Many men after age 45-50 encounter the impotence problem where an erection can not be achieved or maintained. A unique medication ‘Viagra’ can solve this sensitive nuance.

This drug has a stimulating impact on the penis and can last for up to a couple of hours.

What is Sildenafil?

In order to use Sildenafil, a different form of Viagra, correctly and make excellent use of it, the instructions, contraindications and possible side effects should be thoroughly read. You can get the medicine from South African internet pharmacy stores without leaving your house.

In contrast to the conventional Viagra, it takes approximately 30 minutes to a few hours before the erection will become strong. For men younger than 50, it is recommended to start with a lower dose of Sildenafil for a short period of time, as the patient has the possibility of a more prolonged erection and more serious discomfort afterwards.

The medicine is based in the form of citrate on the primary active ingredient of Sildenafil. Additional components include pyrophosphate of anhydrous calcium, stearate of magnesium, titanium dioxide and lactose.

It is accessible in tablet form, coated with a thin layer, with the active ingredient being 50 ‘100 mg. The drug is provided in individual segments and packaged in the packaging of cardboard.

The tablet and capsule forms are available in different sizes from 1 mg up to 10 mg.

It is available in two forms: an empty tablet (red), and a sachet containing the active ingredient (yellow).

These capsules also contain the pharmaceutical formulation and, together with the capsule, provide a tablet preparation that is not only better suited for the daily use but also more convenient at the time of administration.

How its works?

This medicine promotes a standard response to the masculine body’s sexual stimulation. After sexual stimulation, the physiological mechanism that creates an erection is impossible without nitrogen release in the cavernous organs. Nitric oxide stimulates the action of a unique guanylate cyclase enzyme, which raises the amount of cyclic guanosine monophosphate, relaxes the cavernous body muscles, and reduces the flow of blood within the intimate organ. Sildenafil is a selective PDE5 inhibitor that allows the cavernous body to decay cGMP. Therefore, the medicine has a peripheral impact on penis erection.

Viagra is usually well tolerated by healthy males when used once at a dose not exceeding 100 mg. After taking it, the outcome can be observed from 30 to 60 minutes. Some 60 minutes before sexual activity, tablets are taken internally. The suggested dose is 50 mg once daily for the first time.

The dose can be reduced to 25 mg or increased to 100 mg when considering the drug’s individual tolerance and efficacy. The highest single dose is 100 mg.

Individuals over the age of 65 should not alter their dose.
