Basic Pharmacology Quiz – Part 1 Test your basic pharmacology knowledge – Level : Easy 1. Pharmacokinetics is: The study of biological and therapeutic effects of drugs The study of methods of new drug development The study of absorption, distribution, metabolism and excretion of drugs The study of mechanisms of drug action Correct!Wrong!-2. What does “pharmacokinetics” include? Influence of drugs on genes Complications of drug therapy Influence of drugs on metabolism processes Drug biotransformation in the organism Correct!Wrong!-3. What does “pharmacokinetics” include? Pharmacological effects of drugs Chemical structure of a medicinal agent Distribution of drugs in the organism Unwanted effects of drugs Correct!Wrong!-4. What does “pharmacokinetics” include? Excretion of substances Interaction of substances Localization of drug action Mechanisms of drug action Correct!Wrong!-The main mechanism of most drugs absorption in GI tract is Endocytosis and exocytosis Passive diffusion (lipid diffusion) Filtration (aqueous diffusion) Active transport (carrier-mediated diffusion) Correct!Wrong!-What kind of substances can’t permeate membranes by passive diffusion? Hydrophilic substances Non-ionized substances Hydrophobic substances Lipid-soluble Correct!Wrong!-A hydrophilic medicinal agent has the following property: Easy permeation through the blood-brain barrier Low ability to penetrate through the cell membrane lipids Penetrate through membranes by means of endocytosis High reabsorption in renal tubules Correct!Wrong!-What is implied by «active transport»? Transport without energy consumption Engulf of drug by a cell membrane with a new vesicle formation Transport of drugs trough a membrane by means of diffusion Transport against concentration gradient Correct!Wrong!-What does the term “bio-availability” mean? Fraction of an uncharged drug reaching the systemic circulation following any route administration Amount of a substance in urine relative to the initial doze Permeability through the brain-blood barrier Plasma protein binding degree of substance Correct!Wrong!-The reasons determining bio-availability are: Extent of absorption and hepatic first-pass effect Glomerular filtration rate Amount of a substance obtained orally and quantity of intakes Rheological parameters of blood Correct!Wrong!- Share the quiz to show your results !
