Buy viagra Australia over the counter

Viagra is a drug for restoring erectile function in men. All men, who want to take a reliable and proven medication to restore sexual health, can buy Viagra. In Australia, this drug is the most popular means for increasing potency.

A therapeutic group of medicines to which Viagra belongs to is called PDE5 inhibitors. Cellular enzyme plays a key role in physiological mechanism of erection. PDE5 blocks release of nitric oxide in cavernous tissue of the penis. As a result of blood circulation disorder in the penis, a man fails to achieve an erection.

Viagra inhibits activity of PDE5, resulting in increased release of nitric oxide and blood supply of cavernous tissue of the penis. Increase in blood flow to the penis allows a man to achieve erection sufficient for a full sexual intercourse.

  • Thus, Viagra helps to restore erectile function and physiological response to sexual arousal.

With the support of the Pharmacy Guild of Australia, Viagra is sold at the most pharmacy chains. To purchase this drug, a prescription of the attending physician is required. To avoid a need for medical examination, a man can buy Viagra online without a prescription. Some online pharmacies can provide a next day delivery of Viagra.

Each tablet contains 25, 50 or 100 mg of the active ingredient Sildenafil. After intake, Viagra is rapidly absorbed from the gastrointestinal tract. After consumption of fatty and high-calorie food, rate of drug absorption decreases without loss of therapeutic effectiveness.

  • The maximum concentration of Viagra in the blood plasma is reached 60 minutes after the dose intake. Final half-life of the drug makes about 3-5 hours.

Viagra is a drug with minimum frequency of administration – once a day. Most men achieve erection after taking 50 mg of Viagra. Depending on efficacy and tolerability of this PDE5 inhibitor, the daily dose can be reduced by 25 mg, or increased to 100 mg.

Due to the fact that PDE5 enzymes are not only in cavernous tissue of the penis, but also in smooth muscle cells of arteries and veins, a question about safety of Viagra application for patients with cardiovascular diseases arises.

According to experts from non-profit organization Impotence Australia, Viagra is safe for restoration erectile function in patients with minor risk factors for cardiovascular diseases. Cardioprotective effects of Viagra are manifested in:

  • decreased systemic vascular resistance;
  • insignificant effect on the heart rate;
  • positive effect on contractile function of the myocardium.

Viagra is the first drug based on Sildenafil and the first inhibitor of PDE5. Developed in 1989 by doctors Peter Dunn and Albert Wood from Pfizer company, Sildenafil was originally intended as a medicine for normalizing blood pressure and heart rate recovery.

The first phase of clinical trials on effectiveness of a new drug for treatment of cardiovascular diseases was unsuccessful. However, it was noted that Sildenafil administration caused an erection in men during researches.

Further clinical trials of Sildenafil already as a drug for restoring sexual health were successfully completed in 1996 and the drug was patented. On March 27, 1998, Viagra was approved in the USA for treatment of erectile dysfunction. On September 4, 1998, the pharmaceutical company Pfizer received a marketing authorization for Viagra pills in Australia.

If price of this drug is too high at usual pharmacy, a man can order Viagra online at a reduced price. In addition, instead of the expensive brand, one of the cheap Viagra analogs can be used to restore erectile function: Vedafil, Ernafil, Sildanil, Mevia, Silerec, Lisan, Silaran, Zelnafil, Sildocor and Vasafil. This drug for restoration of sexual health is also sold under its own non-proprietary name.
