Content Overview
Explore a variety of topics covered in the app.
Example questions
Let's look at some sample questions
Which factor significantly impacts oral drug absorption by altering gastric emptying time?
Food intakeDrug pHPlasma protein bindingMetabolic rate
Food intake can slow down gastric emptying time, affecting the rate and extent of drug absorption.
Which factor most influences the volume of distribution of a drug?
Drug ionizationPlasma protein bindingDrug half-lifeExcretion route
Drugs tightly bound to plasma proteins have limited distribution into tissues, resulting in a smaller volume of distribution.
Which Phase II reaction involves adding a glycine molecule?
GlucuronidationAcetylationSulfationAmino acid conjugation
Amino acid conjugation, often with glycine, helps in solubilizing and detoxifying certain drugs, facilitating excretion.
Which enzyme is primarily responsible for phase I oxidation reactions in drug metabolism?
Cytochrome P450GlucuronosyltransferaseGlutathione S-transferaseN-acetyltransferase
Cytochrome P450 enzymes mainly catalyze phase I oxidation reactions, enhancing drug solubility.
A patient has reduced N-acetyltransferase activity. Which drug metabolism phase is mainly affected?
Phase IIPhase IBoth Phase I & IINone
N-acetyltransferase is involved in Phase II conjugation, impacting drug detoxification and solubility.
Which receptor subtype does GABA bind to, resulting in inhibitory effects in the CNS?
GABA-AGABA-BNMDAAMPA
GABA-A receptors are ionotropic receptors in the CNS that mediate inhibitory neurotransmission by allowing chloride ions to enter the neuron.
Nicotine's effects on skeletal muscle are primarily mediated by which receptor type?
Muscarinic receptorNicotinic receptorAlpha-adrenergic receptorBeta-adrenergic receptor
Nicotinic receptors, particularly at neuromuscular junctions, mediate the effects of nicotine on skeletal muscle, not muscarinic or adrenergic receptors.
What effect does an agonist have on a receptor?
Depresses receptor activityBlocks receptor activityActivates receptorsDestroys receptor sites
An agonist binds to a receptor and activates it to produce a biological response.
In treating overdoses, a competitive antagonist might be used to:
Enhance drug actionBind irreversiblyBlock receptor bindingActivate receptors
Competitive antagonists block receptors, counteracting the effects of an overdose by preventing binding of excess agonists.
A drug has an ED50 of 20 mg and a TD50 of 200 mg. Calculate the therapeutic index.
1020155
The therapeutic index (TI) is calculated as TD50/ED50. In this case, TI = 200 mg / 20 mg = 10. Calculation verified: 200 divided by 20 equals 10.
