What is Pharmacokinetics? Pharmacokinetics (PK) is a division of pharmacology which attempts to study how the body responds to a drug or other substances like pharmaceutical drugs, food additives, cosmetics, pesticides, drugs, and more. It also involves how the body metabolizes the substance and how and where it is distributed through your entire body when it is taken. It is important to know what this drug does to help you understand how it works.
In order to understand how Pharmacokinetics and Pharmacodynamics are related you must first understand the basics. First, both Pharmacology and Pharmacokinetics are the study of how drugs affect your system. Secondly, both are important for proper drug design, dosage, and even function. And finally, both are affected by nutrition and lifestyle choices.
Before delving too deeply into what is Pharmacokinetics, it is best to understand what is Pharmacology. Pharmacology is the study of how drugs affect your bodily functions. For instance, pharmacology can study drugs effect on blood pressure levels, heart rate, temperature, digestive system, the nervous system, endocrine system, etc. A big part of drug discovery and development is the ability to screen large numbers of drugs to look for specific drug response in a wide variety of biological systems. This ability alone opens up a lot of opportunities for drug research and development.
Pharmacokinetics and Pharmacodynamics both deal with how the concentration and rate of drugs in a bloodstream are affected by external factors. Pharmacokinetics is concerned with how drugs are absorbed, digested and eliminated from the body. Pharmacodynamics deals specifically with how drugs act on cells in culture and how those actions affect cell cultures. Obviously there are many similarities between Pharmacokinetics and Pharmacodynamics.
Pharmacokinetics focuses on how drugs are absorbed, digested and eliminated. This includes how drugs cross the blood-brain barrier, how they interact with other drugs and cells, how they interact with the immune system and the extent to which they are metabolized by the liver. Pharmacokinetics is very important in drug discovery and development as it deals directly with the biology of how drugs work in the body. It also provides information necessary for designing drug treatments. By studying pharmacokinetics, scientists have been able to determine how different drugs may affect brain cells and how certain combinations of drugs may increase or decrease the effects of other drugs.
Pharmacokinetics and pharmacodynamics complement each other and are often used together in research studies that test the effects of new drugs. For example, researchers may test the effects of nps on memory by assessing how its affects concentrations of up in the blood. Or they may test the effect of an anti-depressant drug on concentrations of blood concentrations of the neurotransmitter serotonin. The two forms of pharmacokinetics complement each other by determining how they affect the levels of important compounds within the body.
Pharmaceutical companies rely heavily on the results of both Pharmacokinetics and Pharmacodynamics tests in the development of new drugs. Unfortunately, drug companies have not been able to develop all of the drugs on the market without having some success due to poor understanding of how these systems work. As a result, drug companies continue to suffer from what one pharmaceutical professor has termed as the “pharmacogenetic imbalance.” He has stated that without a better understanding of how certain drugs work in the body, drug companies will continue to produce drugs that are ineffective. Due to this problem, pharmaceutical researchers have been searching for a way to better understand how and why this imbalance occurs.
In order to find a cure or treatment for diseases such as cancer, researchers are always looking at new ways to better understand how specific drugs interact with the body. However, one area that has shown a great deal of promise is the study of how two closely related systems, Pharmacokinetics and Pharmacodynamics affect the absorption rate and elimination of toxins within the body. By combining both Pharmacokinetics and Pharmacodynamics in their studies, researchers have been able to determine how to better regulate the two key areas, allowing the body to better absorb and eliminate various medications. Using information from Pharmacokinetics and Pharmacodynamics tests, researchers have also been able to determine how to increase blood flow throughout the body, allowing certain medications to be more readily absorbed.
