Treatments for erectile dysfunction are widely known through brand names such as Viagra, Cialis and Levitra. Many people assume, wrongly, that these names refer to the drugs themselves. In fact they are brand names. We are less familiar with the names of the drugs, or active ingredients themselves. In many cases, where a pharmaceutical company has developed a drug themselves, they are granted a period of exclusivity in the form of a patent. Viagra is made by pharmaceutical company, Pfizer, and in June 2013 the patent protection for the drug expired in the UK. As mentioned above, Viagra is just a brand name. The actual drug is called sildenafil. Now that Pfizer’s patent has expired, customers can buy sildenafil in the UK from other providers under other brand names. One such alternative brand name is Kamagra. Men experiencing erectile dysfunction can now buy Kamagra online from UK pharmacists, just as you can Viagra.
How Kamagra uk works
When customers buy Kamagra in the UK they can be sure that they are buying exactly the same active ingredient, sildenafil citrate, that is present in branded Viagra. In fact, Kamagra 100mg pills contain a full 100mg of sildenafil citrate. Many men experience erectile dysfunction (ED) due to insufficient blood entering the penis. This prevents the penis becoming hard and erect enough for satisfactory sexual intercourse, leading to impotence. When men buy Kamagra in the UK the actual drug they are purchasing, sildenafil citrate, works with the erectile tissue in the penis to allow more blood to flow in and cause an erection. The way it works is quite simple. During sexual arousal, nitric oxide is released into the erectile tissue. This activates an enzyme which leads to relaxed blood vessels and more blood in the penis. A second enzyme blocks this process and causes loss of erection. Sildenafil citrate simply blocks this second enzyme, allowing the erection to be achieved and maintained.
How to use Kamagra
Men buy Kamagra UK to treat erectile dysfunction just as they buy other ED drugs. One pill of Kamagra should be taken approximately one hour before sex is planned. In most cases the effects will become apparent faster, helping men achieve an erection within 30 minutes. The effects normally last for around four hours. This does not mean that an erection will necessarily last that long. The effects of the drug will only remain while the user is aroused and between periods of stimulation the penis will return to its normal state. Kamagra will not work if the user is not sexually stimulated. After users buy Kamagra in the UK, they should take one pill with a glass of water. Users should note that a heavy, fatty meal can prevent Kamagra working, so for best results it should be taken on an empty stomach. Users should take only one pill in every 24 hours. Kamagra 100mg is not intended as a regular medication and the user need not take the drug on a daily basis. Instead they should only take as directed when they intend to have sex. Tablets should be stored in a cool, dry place and remain in their blister pack until use.
Branded and generic medicines
As mentioned above, some people are unclear about the differences between branded and generic medicines, so it is worth spending some time to explain the processes in the pharmaceutical industry. Developing a new drug is an expensive and time consuming business. In some cases the cost can reach £1 billion. Many hurdles have to be overcome and exhaustive trials and tests carried out to make sure that the medicine is safe and effective. This represents a considerable investment in time and money for any company and this is recognised by governments worldwide. To protect that company’s investment and to encourage further research, the company is granted a period of exclusivity to market the drug, recoup their costs and make a profit. The standard patent period is 20 years.
You can now buy Kamagra UK because the patent for Viagra has expired. It is right and proper that companies are able to recoup their investment in drugs but it is also recognised that drugs should be as widely available as possible to obtain maximum benefit for as many people as can be treated. Customers who buy Kamagra UK can do so at less cost than the branded Viagra and this brings the benefits of the drug to more people. Users who buy Kamagra in the UK are benefiting from the same active ingredient as those purchasing branded Viagra. It should be remembered that GPs in the UK are actively encouraged to prescribe generic rather than branded drugs as the cost to the patient and NHS can be substantially lower. No difference in effectiveness can be implied between branded and generic drugs and users who buy Kamagra in the UK should experience similar results to those achieved by branded products.
