Basics Of Clinical Research Tampa Researchers May Find Beneficial

By Barbara Walker

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.

Before a drug is put on trial, it has to undergo certain processes to ensure it is safe for use in test subjects. Such processes will determine characteristic features of a potential drug including its absorption, distribution, metabolism and excretion from the body. This is referred to as the pharmacokinetics of the drug. Pre-clinical studies also try to find out the pharmacodynamic nature of the substance in question. Pharmacodynamics refer to the reaction of the body to the drug including its desired and adverse side effects. At the end of a pre-clinical study, researchers are in a position to decide just how much of the drug can be tolerated by a given individual.

In some instances, medical equipment is usually the one undergoing scientific studies to facilitate diagnosis and treatment of disease. In this case, the device does not need to go through the initial pre-clinical phase as drugs do. Medical devices instead are taken through what is good laboratory practices with the aim of ascertaining whether the equipment is sustainable in the human body and just how safe it is for use.

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.

Healthy individuals are the most suitable subjects for study. Unfortunately, these same individuals are bound to react negatively to the drug. Some money is usually offered to them to cater for any inconvenience caused. Terminally ill patients as well as patients unable to recover with already approved medication can join in the trial.

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.
