Generic Names, Brand Names & Classifications

1. A prescription is written for "Lipitor 20mg." What is the generic name of this medication?

Lipitor is the brand name for atorvastatin, an HMG-CoA reductase inhibitor (statin). Simvastatin (Zocor), rosuvastatin (Crestor), and pravastatin (Pravachol) are other statins with different generic/brand pairings.

2. Metformin belongs to which drug classification?

Metformin is a biguanide that decreases hepatic glucose production and improves insulin sensitivity. Sulfonylureas (e.g., glipizide), SGLT2 inhibitors (e.g., empagliflozin), and DPP-4 inhibitors (e.g., sitagliptin) are other classes of oral diabetes medications with different mechanisms.

3. Which of the following is the brand name for amoxicillin/clavulanate?

Augmentin is the brand name for amoxicillin/clavulanate, a penicillin combined with a beta-lactamase inhibitor. Zithromax (azithromycin), Keflex (cephalexin), and Bactrim (sulfamethoxazole/trimethoprim) are different antibiotic classes.

4. A pharmacy technician sees an order for "HCTZ 25mg daily." What drug classification does this medication belong to?

HCTZ (hydrochlorothiazide) is a thiazide diuretic used to treat hypertension and edema. Loop diuretics (e.g., furosemide) and potassium-sparing diuretics (e.g., spironolactone) work at different sites in the nephron; ACE inhibitors (e.g., lisinopril) are a separate antihypertensive class.

5. Omeprazole and pantoprazole both belong to which drug class?

Omeprazole and pantoprazole are proton pump inhibitors (PPIs) that reduce gastric acid secretion. H2 receptor antagonists (e.g., famotidine) work through a different mechanism, as do antacids and prokinetic agents like metoclopramide.

6. What is the brand name for levothyroxine?

Synthroid is a common brand name for levothyroxine, a synthetic T4 thyroid hormone. Armour Thyroid is a desiccated animal-derived thyroid product, Cytomel is liothyronine (T3), and Tapazole (methimazole) treats hyperthyroidism, not hypothyroidism.

7. Which classification best describes albuterol?

Albuterol is a short-acting beta-2 agonist (SABA) used for quick relief of bronchospasm. Salmeterol is an example of a LABA, fluticasone is an inhaled corticosteroid, and montelukast is a leukotriene receptor antagonist.

8. A patient profile shows "Norvasc 5mg once daily." What is the generic name of Norvasc?

Norvasc is the brand name for amlodipine, a calcium channel blocker. Losartan is an ARB, metoprolol is a beta blocker, and diltiazem is a different calcium channel blocker with distinct dosing and indications.

9. Warfarin belongs to which drug classification?

Warfarin is a vitamin K antagonist that inhibits synthesis of clotting factors II, VII, IX, and X. DOACs like apixaban work through a different mechanism (direct factor Xa or thrombin inhibition), antiplatelet agents like clopidogrel prevent platelet aggregation, and thrombolytics like alteplase actively dissolve existing clots.

10. What is the generic name for the brand-name drug Glucophage?

Glucophage is the brand name for metformin. Glyburide and glipizide are sulfonylureas, and pioglitazone is a thiazolidinedione — all are different classes of oral diabetes medications from metformin's biguanide class.

1. Sertraline and fluoxetine are both classified as which type of medication?

Sertraline (Zoloft) and fluoxetine (Prozac) are both SSRIs. Amitriptyline is an example of a TCA, phenelzine is an MAOI, and venlafaxine is an SNRI — each class has distinct mechanisms and side-effect/interaction profiles.

2. A technician receives a prescription for "Xarelto." What class of medication is this?

Xarelto (rivaroxaban) is a direct oral anticoagulant that inhibits Factor Xa. Warfarin is the classic vitamin K antagonist; clopidogrel is an antiplatelet agent; these classes work through different pathways in the clotting cascade.

3. What is the brand name for the generic drug gabapentin?

Neurontin is the brand name for gabapentin. Lyrica is a related but distinct medication (pregabalin), and Depakote (divalproex) and Keppra (levetiracetam) are other anticonvulsants with different chemical structures.

4. Prednisone and methylprednisolone both belong to which drug class?

Prednisone and methylprednisolone are both systemic corticosteroids used for their anti-inflammatory and immunosuppressive effects. NSAIDs like ibuprofen work through a different pathway (COX inhibition), and biologic immunosuppressants like adalimumab are a structurally distinct class.

5. What is the generic name for the brand-name drug Coumadin?

Coumadin is a brand name for warfarin. Heparin and enoxaparin are injectable anticoagulants (unfractionated and low-molecular-weight, respectively), and apixaban is a DOAC — all distinct from warfarin's oral vitamin K antagonist mechanism.

6. Which classification describes hydrochlorothiazide combined with lisinopril (Zestoretic)?

Zestoretic combines hydrochlorothiazide (a thiazide diuretic) with lisinopril (an ACE inhibitor) — a common combination antihypertensive. The other pairings listed are real drug-combination categories but do not match this specific product.

7. A prescription reads "Zoloft 50mg." What is the generic name?

Zoloft is the brand name for sertraline. Citalopram (Celexa), paroxetine (Paxil), and escitalopram (Lexapro) are other SSRIs with the same drug class but different generic identities and brand names.

8. Ondansetron is classified as which type of medication?

Ondansetron (Zofran) is a 5-HT3 receptor antagonist used to prevent nausea and vomiting, often in chemotherapy or post-operative settings. It is not a PPI, antihistamine, or opioid — those classes treat different conditions through different mechanisms.

9. What is the brand name for the generic drug albuterol/ipratropium?

Combivent is the brand name for the combination of albuterol and ipratropium. Advair and Symbicort combine a LABA with an inhaled corticosteroid, and Spiriva (tiotropium) is a standalone long-acting anticholinergic — all treat respiratory disease but through different combinations.

10. Clopidogrel is classified as which type of medication?

Clopidogrel (Plavix) is a P2Y12 inhibitor that blocks platelet aggregation. Warfarin is the vitamin K antagonist, dabigatran is a direct thrombin inhibitor, and rivaroxaban is a Factor Xa inhibitor — all anticoagulants/antiplatelets but with different mechanisms.

1. What is the generic name for the brand-name drug Prilosec?

Prilosec is the brand name for omeprazole. Esomeprazole (Nexium), lansoprazole (Prevacid), and rabeprazole (Aciphex) are all in the same proton pump inhibitor class but are chemically distinct generic drugs with their own brand names.

2. Furosemide belongs to which drug classification?

Furosemide (Lasix) is a loop diuretic that acts on the loop of Henle and produces a strong diuretic effect. Thiazides (e.g., HCTZ) act on the distal tubule, potassium-sparing diuretics (e.g., spironolactone) act on the collecting duct, and osmotic diuretics (e.g., mannitol) work through a different mechanism entirely.
