A Few Concepts On Clinical Research Tampa Residents May Find Worthwhile
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.
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.
Phase one of the trial is like the pre-clinical phase only that this time round human beings are used instead of animals. The number of subjects ranges from two to a hundred. This stage takes time to evaluate the dose that is needed to cause desired effect. It is at this stage that the best formulation is decided upon. Safety and toxicity is an additional concern.
Individuals who are healthy are the preferred choice to be used for these studies. People living with advanced cancer are an alternative. Patients who have failed to respond to standard medication are also commonly enrolled in research programs. Ethical guidelines dictate that the individuals signing up for the research receive some financial help to offset any side effects that may occur.
The second and third phases involve a larger number of patients for testing. While phase three needs a maximum of three hundred, the following phase involves way more than this number. The goal at this stage is to study how efficient the drug in question is.
The final step is phase four which is mainly a surveillance stage. This step can be used to study additional possibilities such as the effect of certain medication in pregnant women or children. Such special groups are usually hesitant to participate in the earlier stages because of the high risk involved and can only be included after successful tests in healthy adults.
