The Phases of Clinical Trials
Whenever a new drug has been manufactured or is in the research process, clinical trials are conducted. Live humans are used for this exercise which takes place during a clinical research project. Researchers are always working to provide cures and control on a variety of medical conditions. On the other hand, recently developed medicine may need further testing before public consumption commences. The developers would like to recognize its medical capabilities as well as negative effects. Florida clinic trials also take place in clinics located all over Florida, medical facilities and hospitals. Researchers must obtain consent before subjecting someone to a test.
Before conducting clinical trials, researchers and moderators look for volunteers. Invitations may be made through press appeals or during public health awareness campaigns. The mode of the clinical research is also brought to the public’s attention. Not everyone will be allowed to participate in clinical trials. There are certain criteria for the selection of participants.
One may wonder why someone would volunteer to participate in clinical trials. You may have been affected by a certain illness, a friend or relative may have succumbed to a medical condition. Such occurrences move people to volunteer as a way of giving back to the community or an act of mercy on affected family members and friends. Other people take part in clinical research for the sake of aiding the research process. Clinical studies in Florida for instance must be conducted on volunteers who are in perfect health.
Clinical trials are conducted in stages. The methodology is the same for clinical trials in Miami, Jacksonville or anywhere else in the United States. Once a drug passes the first stage successfully, it moves on to the next. Sometimes the drug may undergo several years of clinical research. The tests are conducted within laboratories where animals may initially be used. A series of intense tests are repeatedly done using several dosages and the results carefully recorded.
Generally clinical trials go through four phases. A zero phase which makes use of 10-15 volunteers is also part of the trials phase. In the zero phase, clinical research personnel administer small doses of the drug to test for safety. The first phase covers 20-100 volunteers. The dosage levels are gradually increased. In this phase researches are interested on safety and toxicity levels. Volunteers in this stage should be in perfect health.
Around 20 to 300 participants are used for Phase 2. The key feature of this clinical trials phase is to allow clinical research staff to test for performance. They also establish what dosage would be required for the condition this drug is being manufactured to treat. During Phase 3, volunteers should range from 300 to 3000. This number requires clinical trials to spread to a number of health facilities. Compatibility tests are carried out in comparison with existing medication and a clinical research assessment report tabled. The final phase, number 4, is after adoption of the report. The drug is marketed and final studies are conducted on behavior of the drug if used with others.
