GENERAL PHARMACOLOGY
Branches of Pharmacology.
Definition and classification of drugs: medicament; poison (or toxic); causal or etiological, pathogenetic, symptomatic, replacement drugs; orphan drugs.
Origin and nature of the drugs: drug from natural origin, drug from partial chemical synthesis, drug derived from chemical synthesis.
Selective toxicity.
Drug action: sites of drug action (local, regional, systemic); factors and conditions affecting drug effect (related to drug, to formulation, to patient, to environment); (main or therapeutic, secondary and side) drug effects.
Pharmacodynamic concepts: definition, classification and regulation of receptors; agonists, antagonists, partial agonists, inverse agonists; definition of affinity, potency and efficacy; graded and quantal dose-response curves; therapeutic index, margin of safety, therapeutic window.
Pharmacokinetics: drug absorption, distribution, metabolism, and excretion.
Drug absorption: transfer of drugs across biological membranes (passive diffusion, carrier-mediated transport, endocytosis, exocytosis); Henderson-Hasselbach equation; routes of drug administration (natural and artificial), factors affecting drug absorption (related to drug, to formulation, to patient); delayed absorption.
Distribution of drugs in the body: drug binding to plasma proteins and tissue; blood-brain barrier; placental barrier; factors affecting drug distribution.
Drug metabolism or biotransformation: phase I and phase II reactions; first-pass effect; factors affecting drug metabolism (enzyme inhibition and induction, genetic polymorphism, disease, age, gender).
Drug excretion: primary and secondary routes of drug excretion; factors affecting drug excretion.
Pharmacokinetic parameters: bioavailability and bioequivalence; volume of distribution; one- and multicompartment models; (total, renal, pulmonary, hepatic) clearance; first and zero order elimination kinetics; extraction ratio; elimination half-life; drug accumulation; steady-state; loading dose, maintenance dose, therapeutic drug monitoring, drug dosage in children and elderly.
Adverse drug reactions: type A and type B; idiosyncratic drug reactions; drug allergy; tolerance; tachyphylaxis; drug dependence; withdrawal syndrome; phototoxicity.
Combination therapy: drug indifference; (physicochemical, pharmacokinetic, pharmacodynamic) drug interactions
Drug development: toxicological animal testing (acute, subacute and chronic toxicity, effects on reproduction, carcinogenic and mutagenic potential); clinical testing (phases I, II, III, IV).
