New drug for high blood pressure: Just a few injections

There is no need to take medicine all the time. . Just one injection of 3 doses, effective from 6-12 months to control high blood pressure. Another new achievement of the world pharmaceutical industry.

British scientists have just released a vaccine to treat high blood pressure. This vaccine has very few side effects compared to tablets and patients need only inject once every 6 months after the first injection.

Protherics Pharmaceuticals Company in Cheshire, West North England, has successfully tested the vaccine on humans and is planning to experiment more widely with an innovative formula to improve treatment effectiveness.

The team said the injectable drug uses a protein found in stellar stars (a shellfish) that inhibits angiotensin, a hormone produced by the liver. When working too hard, this substance will narrow the arteries and push blood pressure up.

When injected into the body, the vaccine will mobilize the immune system against the endocrine substance above and help the body to control blood pressure more easily.

At the beginning of treatment with this vaccine, the patient will receive the first injection of 3 times, once a week or half a month apart. And every 6 months, even 1 year, you have to get additional injections. Test results show that the vaccine is highly effective and has very few side effects, with about 10% of patients having transient symptoms like mild and non-persistent flu.

According to experts, high blood pressure doubles the risk of death from heart disease and stroke, and is responsible for about 60,000 deaths in the UK each year.

Until now, people with high blood pressure had to rely on pills that often caused side effects. For example, 'Beta blockers' (beta receptor blockers) can make patients tired, cold hands and feet, diarrhea, and impotence (in men). These symptoms are associated with an increased risk of stroke.

Andrew Heath, an expert at Protherics, said: 'The birth of this vaccine will help patients better adhere to the treatment plan, and furthermore, make an important contribution to avoiding anvil complications Life threatens like stroke or heart attack. "

Hoping to bring this product to market in the next 5 years, Protherics is preparing to conduct new tests to increase the vaccine's stimulating effect 10 times more than the dosage form. original

Professor Graham MacGregor of the High Blood Pressure Association said: 'High blood pressure is the most important cause of stroke and heart disease in the UK'. Therefore, he welcomed the positive results obtained from these vaccine trials.

He stressed: 'If you have to take antihypertensive tablets, you have to take it for life, and that is difficult for some people. Therefore, finding new and more effective therapies to lower blood pressure with almost no side effects is a huge success.

Dr Mike Knapton, of the Heart Institute in the UK, said: 'More than 20% of heart disease cases in Western Europe come from a history of high blood pressure. The introduction of this vaccine is a right direction but further research is needed. '

It is not clear whether the cost of producing this vaccine is high, but experts believe that when it is marketed, it will not be much more expensive than current blood pressure tablets.
