What is Clinical Research? Its types and procedures

27.12.2019 14:34:04 - Today, clinical research is one of the most booming fields in the healthcare sector and the pharmaceutical industry.

( - What is Clinical Research? Its types and procedures

Clinical Research
When the new drug is invented is not often usable to public while the drug hasn’t gone through the trials that mean they need to go through the study. This study is necessary to check the drug’s safety, efficacy towards the human population. One can pursue a clinical research course


to enter in this field. While performing the clinical trials the study contain many things like, new drug is not yet approved by FDA , is new drug is already approved by FDA ?, new way to give drugs, such as herbs and vitamins, new tests to find and track disease and drugs or procedures that relieve symptoms.

Clinical Trials
Clinical trials are carefully designed, reviewed and completed. The principal investigator is the person who takes a charge of the trial the PI should be expert in clinical trials. I has the authority to choose the research team, designing the trial, and carry the study.
A clinical trial is a research study that tests a new medical treatment or a new way of using an existing treatment to see if it will be a better mode to avoid and monitor for detect or treat an ailment. Clinical Trials and its phases are also been taught in clinical research course for some novel treatment to go into in medical trial, it has to pass preclinical study. Preclinical studies involve in vitro (i.e. test-tube or Laboratory) study and trial on living thing populations. Broad variety of dosage of the learn medicine is given to living thing subject or to an in-vitro substrate in order to obtain preliminary efficacy, toxicity and pharmacokinetic information.

Types of clinical trial
1- Pre-clinical trial- (animal study)
In pre- clinical trial the study of new drug is conducted on the animals and the data is gathered from the pre- clinical trial to further clinical phases

2- Phase 1- (preparatory )
For the first time testing is carried out on healthy human volunteers, with smaller population (20-80).
This phase includes trials designed to assess the safety (pharmacovigillance), tolerability, pharmacokinetics, and pharmacodynamics of a drug. All these te3rms are included in the best clinical research course by Clariwell Global services.

3- Phase 2- (confirmatory)
Phase 2 trials are performed to check the initial safety of the study drug which has been confirmed in phase 1 this phase is performed on the larger groups as 20-300 and is designed to see the how the drug works, as well as to continue phase 1 safety assessments in larger group of volunteers and the patients. Stage II study is every so often alienated into stage IIA and stage IIB. Stage IIA is purposely planned to evaluate dose requirements (how much drug should be given), whereas Phase IIB is specifically designed to study efficacy (how well the drug works at the prescribed dose(s)). Some trials unite Phase I and Phase II, and test together efficiency and toxicity.

4- Phase 3-(therapeutic)
Phase 3 studies are randomized illicit multicenter trials on huge tolerant groups (300–3,000 or extra depending leading the illness/therapeutic state considered) and are intended at creature the authoritative and the strict assessment of how effective the drug is, in comparison with current 'gold standard' treatment. Now for the reason that of the extent and extended period, stage III trials are very costly, long and difficult trials to design and run, especially in therapies for chronic medical.
5- Phase 4-( post marketing)

Stage 4 examination is also identified as Post Marketing Surveillance Trial. Phase 4 trials involve the safety surveillance (pharmacovigillance) and ongoing technical support of a drug after it receives permission to be sold. stage 4 studies can be mandatory by authoritarian establishment or may be undertaken by the sponsoring company for competitive (finding a new market for the drug) or other reasons (for exemplar, the treatment may not have been experienced for connections with other drugs, or on assured inhabitants groups such as significant women, who are not likely to subject matter themselves to trials). The safety surveillance is made to find any sudden or long-term adverse effects on a much larger patient population and longer time period than was possible during the Phase I-III clinical trials.
Clinical Research course is a best choice to learn and enter into the research field.
