Pharmacokinetics, PK for short, is a branch of pharmacology that studies the time course of drugs in the body. Drugs are administered to patients through various routes of administration (such as oral, intravenous, or rectal), and this affects the way a drug moves through the body and the speed at which it is absorbed. Drug blood concentrations are measured over time following dosing. The concentrations are analyzed mathematically to calculate parameters that describe the pharmacokinetics of a drug (biologic or chemical entity). These parameters include concentration-time profiles and other measures such as area under the curve (AUC), maximum concentration (Cmax), and mean residence time (MRT). Such data are used to define dosage regimens such as half-life and dosing intervals, and they help explain how drugs may interact in the body or react under certain circumstances. Data like this can also be used to design modifications to drug products. For example, slow-release formulations can be developed for drugs that are normally rapidly cleared from the blood stream when administered orally. Pharmacokinetic studies also incorporate toxicokinetics, which relates principles of PK to disposition of toxicants and their metabolites and time course of adverse events in the body.
Pharmacokinetics is the study of how your body processes and utilizes prescription medications. Pharmacodynamics involves the relationship between drug (or metabolite concentrations) and a therapeutic response – for example, what the drug does to your body. Pharmacology studies help us understand how medications affect you, as well as their side effects. Clinical pharmacokinetics includes studying how people process and utilize drugs prescribed for them in therapy.
The API is the molecule that produces efficacy. Target identification finds a gene or protein (therapeutic agent) that plays a significant role in disease. When identified, therapeutic characteristics are recorded. Drug discovery meaning: Targets are efficacious, safe, usable as drugs, and capable of meeting clinical and commercial requirements. Researchers use disease association, bioactive molecules, cell-based models, protein interactions, signaling pathways analysis, and functional analysis of genes to validate targets, or in vitro genetic manipulation, antibodies, and chemical genomics. The Sanger Whole Genome CRISPER library and Duolink PLA are excellent sources for drug discovery targets.

API (active pharmaceutical ingredients) are biologically active components of a drug that produce effects. The design of active pharmaceutical ingredients demands a comprehensive understanding of drug-target interactions. Researchers use assays, which are biological tests, to examine and evaluate drugs for their pharmacology and therapeutic efficacy.
