pharmacologiques

Pharmacologiques, the French form of the term pharmacological, refers to aspects of pharmacology—the science of how chemical substances interact with living organisms. Pharmacology studies mechanisms of action, therapeutic effects, and potential adverse reactions of drugs, and it underpins medicine, toxicology, and drug development.

Two central pillars structure pharmacology: pharmacodynamics and pharmacokinetics. Pharmacodynamics describes how drugs affect the body at molecular and cellular levels, including receptor binding, signal transduction, and dose–response relationships. Pharmacokinetics covers absorption, distribution, metabolism, and excretion, determining how the body processes a drug over time.

Drugs can be natural, synthetic, or biologic. They act by binding to targets such as receptors, enzymes, ion channels, or transporters, thereby altering normal biological function. The term pharmacology also encompasses toxicology, which studies harmful effects, exposure thresholds, and risk assessment to inform safety standards.

Applications span drug discovery, preclinical research, and clinical development, culminating in therapeutic use. Dosing strategies, formulation, pharmacovigilance, and post-marketing surveillance aim to maximize benefit while minimizing risk. Regulatory agencies evaluate quality, safety, and efficacy before medicines reach patients.

Advances in pharmacology contribute to personalized medicine through pharmacogenomics and interindividual differences in metabolism and response. The field integrates chemistry, biology, medicine, and data science to understand variability in drug effects and to develop safer, more effective therapies.
