Module 1: Introduction to Pharmacology Flashcards
What is the definition of pharmacodynamics?
Pharmacodynamics is the study of the effects of drugs on the body and the mechanisms of their action.
True or False: Pharmacodynamics exclusively focuses on how the body metabolizes drugs.
False
Fill in the blank: Pharmacodynamics involves understanding the ___ between drug concentration and its effects.
relationship
Which of the following best describes the term ‘receptor’ in pharmacodynamics? A) A type of drug B) A molecule that drugs bind to C) A process of drug elimination
B) A molecule that drugs bind to
What is the significance of dose-response relationships in pharmacodynamics?
Dose-response relationships help determine the relationship between the dose of a drug and the magnitude of its pharmacological effect.
What is drug affinity?
Drug affinity refers to the degree to which a drug binds to its target receptor.
True or False: Efficacy describes the ability of a drug to produce a desired therapeutic effect.
True
Fill in the blank: Potency is a measure of the _____ of a drug required to produce a specific effect.
amount
Which term describes how well a drug activates a receptor once it is bound?
Efficacy
Multiple Choice: Which of the following describes a drug with high potency? A) It requires a large dose to be effective B) It requires a small dose to be effective C) It has low affinity for its receptor D) It has no effect at all
B) It requires a small dose to be effective
What are transporter proteins?
Transporter proteins are integral membrane proteins that facilitate the movement of ions, small molecules, or larger substrates across cellular membranes.
True or False: Transporter proteins can only transport substances into the cell.
False: Transporter proteins can transport substances both into and out of the cell.
Fill in the blank: The binding of drugs to transporter proteins can affect their __________ and __________.
efficacy, distribution
Which of the following is a common type of transporter protein target for drug binding? A) Ion channels B) Enzymes C) SLC transporters D) Receptors
C) SLC transporters
What is the significance of understanding transporter protein targets in drug development?
Understanding transporter protein targets is crucial for predicting drug absorption, distribution, metabolism, and excretion (ADME) properties.
What is a common transport protein receptor target for drug binding that is involved in neurotransmitter transport?
Sodium-dependent neurotransmitter transporters
True or False: P-glycoprotein is a transport protein that can influence drug absorption and distribution.
True
Fill in the blank: The _______ transporter is a key target for drugs aimed at treating heart failure and hypertension.
Sodium-potassium ATPase
Which transport protein is known for its role in the reuptake of serotonin from the synaptic cleft?
Serotonin transporter (SERT)
Name a transport protein receptor target that plays a role in drug resistance in cancer therapy.
Breast cancer resistance protein (BCRP)
