Research in any field is done with an aim of inventing solutions for various situations based on the field of specialty. In clinical research, scientists work to come up with new and better methods of disease prevention and treatment. It also serves to provide temporary solutions to ensure that patients are kept comfortable while definitive treatment is in the process of being established. In this article we discuss details about clinical research Tampa residents may find meaningful.
As the term suggests, pre-clinical trials come right before the trial itself. The pre-clinical phase aims at establishing a safety framework for use of a drug among participants of the main trial. At this stage, important properties ( also known ad pharmacodynamics and pharmacokinetics) of a given drug are studied. Pharmacodynamics refer to the response of the body to the drug. Such will include, for example, the side effects and maximum safe dose. Pharmacokinetics, on the other hand, define how the drug is absorbed, distributed, metabolized and excreted from the body.
Trials may also be designed for testing medical devices rather than drugs. Medical devices are generally invented to enhance the accuracy of diagnosis of illnesses or to maintain functionality when an organ is or has failed. A good example is the artificial pacemaker. For such a device to be approved for use, researchers need to establish just how sustainable it would be for any given individual. Medical equipment and devices have to be taken through the stage of good lab practices to ascertain their safety.
In a bid to hasten the research process, an initial step commonly referred to as phase zero was recently put in place. At this stage, the testing is usually done in animals. Moreover, very minute doses are administered. At the end of day, researchers can deduce which drug is promising enough to continue in the trial process.
The next thing is to recruit a number of individuals ranging from three to a hundred. The main objective is to evaluate certain concerns including efficacy of a given dosage and the toxicity profile of the agent under study. Whether the agent will be in capsule, tablet or in solution form can also be determined at this point.
Usually, healthy persons are used for study. The disadvantage is that these individuals may get sick in the process. Therefore, such people participate at a fee and informed consent is part of preparation. Alternatively, patients who are suffering from certain conditions and have not responded to all the available treatments in the market can sign up for such trials. Another category is that of patients with terminal illnesses.
Phase two of research requires the participation of more than a hundred people. This phase mainly tests for efficacy of a drug on a larger number of individuals. The third phase calls for more than a hundred individuals to participate. It is an intensive phase that seeks to prove the value of a therapeutic agent.
The fourth and final phase emphasizes on getting the finer details. For instance, certain groups of people that may not have been evaluated in at the preliminary level fit in perfectly at this stage. Expectant women and infants are classic examples.
