Pharmacodynamics places particular emphasis on dose–response relationships, that is, the relationships between drug concentration and effect. [1] One dominant example is drug-receptor interactions as modeled by
Pharmacodynamic interactions are the drug–drug interactions that occur at a biochemical level and depend mainly on the biological processes of organisms. These interactions occur due to action on the same targets; for example, the same receptor or signaling pathway.
Drug-Drug Interaction models explore the impact of interactions between different drugs on their pharmacokinetics or pharmacodynamics. These models help predict the effects of co-administered drugs on each other, aiding in the identification of potential risks and the adjustment of dosages in the presence of multiple medications.
Pharmacology is the science of drugs and medications, [1] including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. [2]
Drug-drug interactions can be of serious concern for patients who are undergoing multi-drug therapies. [5] Coadministration of chloroquine , an anti-malaria drug, and statins for treatment of cardiovascular diseases has been shown to cause inhibition of organic anion-transporting polypeptides (OATPs) and lead to systemic statin exposure.
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing , benefit, and adverse effects , as seen in PK/PD models .
The pharmacodynamics of spironolactone are characterized by high antimineralocorticoid activity, moderate antiandrogenic activity, and weak steroidogenesis inhibition. In addition, spironolactone has sometimes been found to increase estradiol and cortisol levels and hence could have slight indirect estrogenic and glucocorticoid effects.
