Globally, medical researchers are researching drugs for the lung disease Covid-19, which is caused by coronaviruses. A combination therapy by medical professionals works.
- The corona virus * is still a mystery to medical professionals.
- Thai doctors are said to have found therapy against the virus infection.
- A combination of two tried and tested medicinal products is said to be effective.
- Other drugs are currently being tested for their effectiveness against Sars-CoV-2.
Update of April 3, 2020: Doctors focus on certain medications in the fight against coronavirus
As reported by the Association of Researching Pharmaceutical Manufacturers (vfa), medicinal products against coronavirus infections that are already approved for another disease or at least in development are currently being used. " Converting them can be done faster than a basic new development, " says the vfa website. The following drug groups are currently being tested for their suitability against Covid-19:
- Antiviral drugs : These were originally developed for HIV, Ebola, hepatitis C, flu *, SARS or MERS (two diseases caused by other coronaviruses) and are designed to block the multiplication of viruses or prevent them from entering lung cells. An old malaria drug is also being tested, according to the vfa, whose effectiveness against viruses has only recently been discovered.
- Immunomodulators , for example against rheumatoid arthritis or inflammatory bowel diseases: These preparations are intended to slow down the body's defense reactions.
- Medicines for lung patients: They are intended to ensure that the patient's lungs can supply the blood with enough oxygen.
Update of March 23, 2020: Austria successfully tests drug against Covid-19
The Salzburg State Clinic is now reporting first successes in the treatment of Covid-19. " A drug can slow down the so-called inflammatory storm . The corresponding data have not yet been published. However, they will be published soon. They show that this can reduce the severity of the disease by 90 percent," said Richard Greil, director of the university clinic , cited by oe24.at. Another drug gives cause for cautious good news, according to Greil, according to Mercury *.

Update from March 17th, 2020: When does the vaccine against the coronavirus come?
Although around 40 vaccine projects are ongoing, it may take some time before an effective vaccine against the novel coronavirus * comes onto the market. The prognoses could not be more different: Some doctors expect an effective vaccine as early as 2021, others suspect that no vaccine substances against Sars-CoV-2 could be found in the future. The British disease expert Jeremy Farrar said in an interview with Spiegel in early February that he believed that a vaccine against the novel coronavirus would be too late to prevent the impending global spread of the disease . "And if we are unlucky, it will never succeed," said his gloomy forecast.
Treatment of Covid-19: Medical professionals use drugs "off-label"
Research is not only focused on vaccine development, researchers are also feverishly looking for antiviral drugs that can be used against Covid-19. For the most part, they concentrate on already approved preparations with the advantage that they can be administered immediately. Antiviral preparations are considered less effective than active substances against bacteria (e.g. antibiotics), but in many cases they can weaken a severe course of the disease. Already at the beginning of the Covid-19 pandemic at the end of 2019, physicians were using "off-label" antiviral medication because (to this day) there are no medications that are specifically effective against the novel pathogen Sars-CoV-2 . "Off-label use" means "improper use": drugs are used against an illness for whose treatment they have no approval from the regulatory authorities.
For example, doctors have used the HIV drug * Kaletra so far, as this has been shown to improve the symptoms of a corona infection *. Some ongoing studies are now to test this scientifically, as reported by the portal Spektrum.

Sars-CoV-2 and Sars pathogen from 2002/2003: Researchers use similar behavior
Researchers are taking advantage of the similarity between the novel Sars CoV-2 pathogen and the Sars corona virus, which triggered a pandemic in 2003 that claimed nearly 800 lives. " Both viruses use very similar strategies to penetrate cells and may also trigger the disease via similar mechanisms, " Spektrum quotes infection biologist Markus Hoffmann from the German Primate Center in Göttingen (DPZ): "The existing knowledge of Sars can therefore help Combat Covid-19 *. " Hoffmann, his team and DZIF scientists from the Charité Universitätsmedizin Berlin came to the conclusion that both viruses use the same cell receptor to dock onto their target cells. They were also able to identify a cellular enzyme that is essential for the virus to enter lung cells: the protease TMPRSS2. An existing drug that inhibits this protease could therefore be a promising treatment option, as reported by the German Center for Infection Research (DZIF).
It is Camostat Mesilate , a drug approved in Japan for inflammation of the pancreas. This is currently being examined to determine whether it can also prevent infection with SARS-CoV-2. "We tested SARS-CoV-2 from a patient and found that Camostat Mesilate blocks the entry of the virus into lung cells," said Hoffmann as lead author of the study: "Our results suggest that Camostat Mesilate was also used before Covid-19 could protect ". But this must be investigated further in the context of clinical studies.
Article from 03/10/2020 : 1,016,401 coronavirus cases have been reported worldwide. There are now 53,160 deaths complained to (as of April 3, 2020). These numbers are extremely worrying, especially because doctors only have symptomatic treatment options , but no causal therapy or even vaccination * is available.
However, Thai doctors are said to have now found a way to successfully treat those affected by combination therapy.

Combination therapy from flu and HIV medication is intended to combat coronavirus infection
Two doctors from the Rajavithi Hospital in Bangkok - specialist Dr. Kriangsak Atipornwanich and Professor Subsai Kongsangdao - said during a conference in the Thai capital that a 71-year-old woman experienced significant improvement in symptoms 48 hours after taking two groups of drugs .
The Bangkok Post further reported that it was a drug cocktail made up of the two drugs lopinavir and ritonavir, which are used for HIV infections * and a flu drug . Two days after the medication was given, the condition of the Chinese patient would have improved significantly, the doctors said.

Effective medication: Chinese patient recovers two days after taking it
AIDS drugs have already been tested in China against the novel coronavirus *. "We checked the related information and also found that anti-flu medication at MERS ( Editor's note : MERS stands for Middle East Respiratory Syndrome Coronavirus, a virus from the coronavirus family that was first mentioned in 2012 , which can cause a serious respiratory infection, pneumonia and kidney failure) , were effective, so we combined the two groups of drugs, "said Atipornwanich. After the medication had been administered, the patient would have recovered quickly, the doctor continued.
The combination therapy is now to be tested further in the laboratory , said the Thai authorities. So far, 1,978 (as of April 3, 2020) coronavirus infections are known in Thailand.
