What Is Pharmacokinetics? What is Pharmacology? These two words have many meanings, but they all come from the same place. Pharmacology is the study of how drugs work and how they affect the body. Pharmacokinetics deals with the way that drugs are absorbed, acted on the body, and how they are excreted from the body. These two concepts are tightly related, and a well-designed pharmacokinetics schedule can help maximize the efficiency of any drug in reducing wastage and maximizing its therapeutic effect.
What is Pharmacokinetics? In simple terms, pharmacokinetics refers to how a drug is absorbed, acted upon, and excreted in the body. The absorption process is how a drug gets into the circulatory system, the distribution process is how the drug gets out of the body, and the excretion process is how the drug is disposed of after usage. This last process is important in that the levels of many hazardous drugs such as pesticides are particularly sensitive to poor excretion methods.
What is Pharmacokinetics? Pharmacokinetics is an area of biology that studies how drugs affect the body. It studies how different molecules interact with one another, how the concentration of a drug in a solution increases as a function of the concentration in aqueous solution, how the concentration of a drug changes as a function of time, how drug receptors are activated, how drug metabolites affect one another, and how the concentration of a drug in the body affects the concentrations of other chemicals within the body. All of these processes are intimately connected and affect how drugs are absorbed, acted upon, excreted, and disposed of.
How is Pharmacokinetics applied in clinical pharmacology? In clinical pharmacology, pharmacokinetics is used to study how drugs work inside the human body. This includes how drugs increase blood pressure, how they block or slow the heart rate, how they cause a decrease in liver function, how they interact with other drugs, how they affect neurotransmitters in the brain, how they interact with environmental agents, and how they affect cell culture. By studying how drugs affect the body, clinical pharmacologists can monitor the health of their patients and create pharmaceuticals that will improve or cure certain diseases.
How do drugs become active inside the human body? Active drugs are transported into the body through three different routes: directly through the blood, by cell-signals via the blood, and by means of metabolic or chemical pathways via the lymphatic system. The direct route is the quickest way to enter the body. Metabolizing drugs, however, creates a “red tide” that carries drugs throughout the body. When a drug is first introduced into the system, it can act at least several hours, if not up to 24 hours, before it begins to lose its activity. Once the red tide sets in, it tends to be difficult to reverse, as the drug’s activity is tightly maintained by red tide cells.
The second route of entry into the body involves the use of blood-based controls, such as blood glucose and insulin concentrations. These controls can effectively measure the amount of drug in the system and thus allow researchers to monitor the levels of drugs in patients’ bodies. The last route of entry is via transdermal patches. These patches deliver small amounts of drugs directly to the target site and have revolutionized how clinical pharmacology is done today. By using transdermal patches, researchers can monitor how a drug is changing the concentration of a disease-causing protein in a human body.
What are Pharmacokinetics And Pharmacodynamics? Is it really true that our bodies are only able to take in a certain amount of a drug at a time? Or do researchers have it all wrong? Scientists have recently been attempting to answer these questions, using a variety of methods, including computer simulation and experimental drug introductions.
While pharmaceutical companies are spending millions of dollars each year on the r&d, they have yet to unlock the answers to what is pharmacokinetics and pharmacodynamics. While it may be impossible to fully define how drugs affect cells, we can still learn a great deal about how they work by studying them under controlled conditions. This is why drug companies often rely on pharmacologists and other medical professionals to help them design and test new drugs. Without the benefit of these outside perspectives, it would be nearly impossible for scientists to truly understand how drugs interact with cells and how different doses will have different effects.
