Pharmacodynamics studies how drugs interact with the body’s receptors, including targeting specific sites, efficiency across age groups, and potential side effects. Ligands connect drugs to receptors, triggering chemical reactions. Effective drugs must work across different ages and disease stages, and unintended consequences must be studied.
Pharmacodynamics is the study of what a drug does to the body. In most cases, it is a study of a drug’s interaction with an intended receptor, the target in the body that binds the drug to a person’s physiological systems. There are several areas of interest in this research field, including targeting drugs to a specific site in the body, drug efficiency across all age groups, and unwanted side effects of a drug. The counterpart to pharmacodynamics is pharmacokinetics, the study of what a body does to a drug.
For most drugs to work, they must target a receptor in the body or a microorganism within the body, such as a bacterial infection. A receptor is a specific type of protein that protrudes from the body of a cell. The drugs are given a different protein, called a ligand, which can connect with the receptor. The two proteins fit together like pieces of a puzzle, and the bond acts as a trigger, setting in motion a course of chemical reactions, like a drug starting the process of fighting a disease. Knowing which type of ligand to bind to a drug is an important part of pharmacodynamics.
One of the most significant areas of study in pharmacodynamics is ensuring that drugs are effective across a wide range of ages and disease stages. As people age, the receptors in their bodies change. Many drugs need receptors to bind to, so drugs with multiple ligands that can bind to multiple receptors may need to be created to cover a range of ages. The same is true for long-term and degenerative diseases, such as Alzheimer’s disease, which goes through many stages and causes a person’s brain cells to deteriorate as the disease progresses. Therefore, a drug that targets late-stage Alzheimer’s would need a different facility than one that targets an early stage of the disease.
Another aspect of pharmacodynamics is learning and understanding all the effects a drug could have in the body once it binds to its intended receptor. The drugs, of course, are supposed to change what’s going on in the body. They can alter the way a virus replicates, inhibit tumor growth, or strengthen the immune system. In the early stages of drug development, however, pharmacodynamics is used to study all the unintended consequences of drug binding. Side effects could include causing damage to cells in the body, inducing cell mutations that could lead to cancerous growths, or in a worst-case scenario, actually increasing the potency of a disease.
