Digoxin Antidote Digoxin immune Fab (Digibind).
Albuterol Stimulates beta2 receptors → bronchodilation.
Albuterol Use Asthma, COPD.

, Pharmacology Mid-Term Exam 1 Questions & Answers
Amlodipine Calcium channel blocker → vasodilation → ↓ BP.
Amlodipine Use Hypertension, angina.
Beta2 agonist → bronchodilation; use: asthma/COPD; avoid in
severe tachyarrhythmias; monitor HR, tremor; teach inhaler
Albuterol technique.
Dihydropyridine CCB → peripheral vasodilation; use: HTN/angina;
contraindicated in severe hypotension; monitor BP, edema; avoid
Amlodipine grapefruit.
Antimetabolite/DMARD → inhibits folate metabolism; use: RA,
psoriasis, chemo; contraindicated in pregnancy; monitor
Methotrexate CBC/LFTs; give folinic acid rescue.
Irreversible COX-1/COX-2 inhibitor → analgesic & antiplatelet;
use: pain & low-dose MI prophylaxis; contraindicated in active
Aspirin bleed/children with viral illness; monitor GI bleed; take with food.
Replaces RBCs/plasma/platelets; use: anemia/bleeding/volume
replacement; contraindicated if incompatible; verify crossmatch,
Blood (Transfusion) monitor for reactions; educate patient on signs of transfusion
reaction.
Constitutive enzyme that protects gastric mucosa & aids platelet
COX-1 aggregation; inhibition → ↓platelet function, ↑GI bleed risk.
Inducible enzyme for inflammation/pain; selective inhibition →
COX-2 ↓pain with less GI upset but possible ↑CV risk.
Cardiac glycoside → ↑inotropy, ↓HR, ↓AV conduction; use: HF, A-
fib; contraindicated: v-fib, heart block; monitor apical pulse, K⁺, dig
Digoxin level; teach toxicity signs; antidote = Digibind.
TNF-α inhibitor monoclonal antibody; use: RA, Crohn's;
contraindicated with active infection/TB; screen for TB, monitor for
Infliximab infusion reactions; avoid live vaccines.
Parenteral anticoagulant → potentiates antithrombin III; use:
DVT/PE prophylaxis & treatment; contraindicated in active bleed;
Heparin monitor aPTT & platelets (HIT); antidote = protamine.
Fluids with osmolality ≈ plasma → expand intravascular volume;
Isotonic Fluids (e.g., Normal use: resuscitation/dehydration; caution in HF; monitor I&O, lung
Saline, LR) sounds.
Draws water from cells to intravascular space; use: severe
hyponatremia/ICP; contraindicated in volume overload; monitor
Hypertonic Fluids (e.g., 3% NaCl) Na⁺ closely.
