From the launch of the plan for the drug to begin trading it normally takes from 10 to 14 years and the point in time from time to time is longer because the authorities who issue a permit are increasingly harsher and require lots evidence of its safety and value.
In the case of the most dangerous illnesses which include cancer, this moment in time is able to be shorter when the first test presented a good clinical efficacy. In this situation, the process takes months, not years.
Firstly, on the found on a particular knowledge of the cell and the nature of the disease is made a molecule.
Then, in the lab the scientists test if this molecule has a definite effect on cancer cells, for example, curb the growth or destroys them completely.
If you manage to prove that the novel molecule posseses the wanted biological results, then begins pet studies. Most tests are carried out on lab rats. It is the first time when we can notice how a potential medicine acts in a living body. The preclinical tests last three or four years.
The next step is clinical studies. They are make by oncology centers. From moment in time to moment in time participation in the test is the last opportunity for patients – their previous treatment does not bring any content results. At special website, you can find data published by pharmaceutical companies. They tell about studies.
If everything goes well, the pharmaceutical corporations can begin the products. They use the specific pharmaceutical tools which can be found only in this industry. Some instances are: polishing machines for punches and dies, measuring machines for punches and more other tools which aim is to produce a tablet which contain an appropriate dose of medicine.
As it can be noticed the pills have to follow a challenging and winding way sooner than they are approved to make a use of. Sometimes, several patients who are not scared of risk, ask pharmaceutical corporations for assistance. Sometimes they do not have any possibilities to become well. Some of inventive tablets are able to help them to save their life.
