Dental Pharmacology flashcards for NEET MDS

20 of 59 cards from the Dental Pharmacology deck — real questions with worked answers.

1. Define pharmacokinetics and name its four main processes (ADME).

   Pharmacokinetics is the study of what the body does to a drug. Its four processes are Absorption, Distribution, Metabolism, and Excretion (ADME).

2. What is the bioavailability (F) of a drug given intravenously, and why?

   100% (F = 1), because the entire dose enters systemic circulation directly without first-pass metabolism or absorption losses.

3. Define the volume of distribution (Vd) and give its formula.

   Vd is the apparent volume into which a drug distributes. Vd = total amount of drug in body / plasma drug concentration. A high Vd indicates extensive tissue distribution.

4. What is the elimination half-life (t½), and how many half-lives are needed to reach steady state?

   t½ is the time for plasma drug concentration to fall by 50%. About 4–5 half-lives are needed to reach steady state (and similarly to eliminate the drug).

5. Differentiate first-order from zero-order kinetics.

   First-order: a constant fraction of drug is eliminated per unit time (rate proportional to concentration). Zero-order: a constant amount is eliminated per unit time (saturated enzymes), e.g., ethanol, phenytoin, aspirin at high doses.

6. What is hepatic first-pass metabolism?

   The metabolism of an orally absorbed drug in the gut wall and liver before it reaches systemic circulation, reducing the fraction of active drug available.

7. Define pharmacodynamics.

   Pharmacodynamics is the study of what the drug does to the body — the biochemical and physiological effects of drugs and their mechanisms of action.

8. Distinguish a drug's potency from its efficacy.

   Potency is the amount of drug needed to produce an effect (related to EC50/lower dose = more potent). Efficacy is the maximum effect a drug can produce regardless of dose.

9. Differentiate an agonist from an antagonist.

   An agonist binds a receptor and activates it to produce a response. An antagonist binds the receptor but produces no response and blocks agonist action.

10. What is the difference between a competitive and a non-competitive antagonist?

    A competitive antagonist binds reversibly at the same site as the agonist and can be overcome by increasing agonist dose (shifts curve right, Emax unchanged). A non-competitive antagonist reduces the maximal response (Emax decreased) and cannot be fully overcome.

11. Define therapeutic index (TI) and give its formula.

    TI is a measure of drug safety. TI = TD50 / ED50 (or LD50/ED50). A higher TI indicates a wider, safer margin between effective and toxic doses.

12. What is a pharmacokinetic drug interaction? Give a dental example.

    An interaction altering absorption, distribution, metabolism, or excretion of a drug. Example: erythromycin inhibits CYP3A4, raising plasma levels of midazolam used for sedation.

13. What is a pharmacodynamic drug interaction? Give an example.

    An interaction at the site of action altering drug effect without changing levels. Example: additive CNS depression when opioids are combined with benzodiazepines.

14. Why should NSAIDs be used cautiously in patients taking warfarin?

    NSAIDs displace warfarin from plasma protein binding and inhibit platelet function/cause GI irritation, increasing bleeding risk (a combined pharmacokinetic and pharmacodynamic interaction).

15. Why are vasoconstrictors (epinephrine) used cautiously with non-selective beta-blockers?

    Unopposed alpha-adrenergic vasoconstriction can cause hypertension and reflex bradycardia, as the beta-blocker blocks epinephrine's vasodilatory beta-2 effect.

16. Define an adverse drug reaction (ADR) and distinguish Type A from Type B.

    An ADR is a harmful, unintended response at normal doses. Type A (augmented) reactions are dose-dependent, predictable extensions of pharmacology (e.g., bleeding from anticoagulants). Type B (bizarre) are unpredictable, not dose-related (e.g., penicillin anaphylaxis).

17. What is gingival hyperplasia and name three drug classes that cause it.

    Overgrowth of gingival tissue. Classic causes: phenytoin (anticonvulsant), cyclosporine (immunosuppressant), and calcium-channel blockers (e.g., nifedipine).

18. Which drug class causes xerostomia and dental implications of it?

    Anticholinergics (and many antidepressants, antihistamines, antihypertensives) cause dry mouth, increasing risk of caries, candidiasis, and periodontal disease.

19. What is the chemical classification of local anesthetics into two groups?

    Esters (e.g., procaine, benzocaine, tetracaine) and amides (e.g., lidocaine, articulate—articaine, bupivacaine, mepivacaine, prilocaine). Amides have two 'i's in the name.

20. How can you tell amide from ester local anesthetics by their generic name?

    Amides contain an 'i' in the prefix before '-caine' (lidocaine, mepivacaine, bupivacaine). Esters have only one 'i' (procaine, benzocaine).
