Basisbegrippen
Zie afbeelding hieronder
Pharmacology: study of the biochemical and physiological effects of drugs on organisms.
Pharmacodynamics: study of the cellular and molecular interactions of drugs with their targets.
Pharmaceutical toxicology: study of the harmful or toxic effects of drugs.
Pharmacokinetics: study of factors that control the concentration–time relationship of drug at various
sites in the body.
Medicinal chemistry: study of drug design to optimize pharmacokinetics and pharmacodynamics, and
synthesis of new drugs.
Pharmaceutics: study and design of drug formulation for optimum delivery, stability, pharmacokinetics,
and patient acceptance.
Pharmacogenomics: study of the influence of genetic variation on drug response in patients.
An ideal drug is one that:
• Has a desirable pharmacological action
• Has no side effects
• Reaches its intended location in the right concentration at the right time
• Remains at the site of action for the necessary period of time
• Is rapidly and completely removed from the body when no longer needed.
Inleiding farmacologie
Farmacologie is een interdisciplinair vakgebied met een breed domein. Het heeft vele raakvlakken met
andere vakgebieden.
Farmacogenomics = Middels een DNA test kunnen individuele reacties op geneesmiddelen worden
bepaald. Medicijnontwikkeling wordt specifieker.
