All Angry Ants Attack Antelopes Alternatively (drug class categories)
General Pharmacology Drug Classes
NEET-PGAIIMSFMGE
Items to Memorize
- Antibiotics (β-lactams, Macrolides, Aminoglycosides, Fluoroquinolones, Tetracyclines)
- Antihypertensives (ACE inhibitors, ARBs, CCBs, β-blockers, Diuretics)
- Analgesics (NSAIDs, Opioids, Paracetamol)
- Antidiabetics (Insulin, Metformin, Sulfonylureas, DPP4i, SGLT2i)
- Antiepileptics (Phenytoin, Carbamazepine, Valproate, Levetiracetam)
- Antipsychotics (Typical: Haloperidol; Atypical: Olanzapine, Risperidone)
- Anticoagulants (Heparin, Warfarin, DOACs)
Mnemonic Tricks
How It Maps
| Cue | Maps To |
|---|---|
| All (Antibiotics) | Antibiotics |
| Angry (Antihypertensives) | Antihypertensives |
| Ants (Analgesics) | Analgesics |
| Attack (Antidiabetics) | Antidiabetics |
| Antelopes (Antiepileptics) | Antiepileptics |
| Alternatively (Anticoagulants) | Anticoagulants |
Why It Sticks
All drug classes start with 'Anti-' — the alliterative animal sentence creates a visual scene of angry ants attacking antelopes, memorable because it's bizarre.
ABCD for Antihypertensives: ACE/ARB, Beta-blockers, Calcium Channel Blockers, Diuretics
How It Maps
| Cue | Maps To |
|---|---|
| A | ACE inhibitors / ARBs (-pril, -sartan) |
| B | Beta-blockers (-olol) |
| C | Calcium Channel Blockers (-dipine) |
| D | Diuretics (Thiazides, Loop) |
Why It Sticks
ABCD follows the BHS/NICE treatment algorithm step order — it's not just a memory trick, it's the actual clinical guideline for starting antihypertensive therapy.
'-pril' blocks ACE, '-sartan' blocks AT, '-olol' slows the heart like a diplomat, '-dipine' relaxes calcium's door, Thiazides flush salt out — need I say more?
Why It Sticks
Drug suffixes are the fastest way to identify classes in MCQs. This rhyme links each suffix to its mechanism in under 30 words.
Frequently Asked Questions
How to remember drug classes in pharmacology?
Start with suffixes: -pril (ACE inhibitors), -sartan (ARBs), -olol (beta-blockers), -dipine (CCBs), -statin (lipid-lowering), -azole (antifungals), -mycin (aminoglycosides). Then use the ABCD mnemonic for antihypertensives.
What are the most important drug classes for NEET-PG?
Focus on: Antibiotics (mechanism + spectrum), Antihypertensives (ABCD), Antidiabetics (insulin types + oral drugs), Analgesics (NSAIDs vs opioids), and Antiepileptics. These cover 60%+ of pharmacology questions.
How to remember antibiotic mechanisms?
Cell wall synthesis inhibitors: β-lactams (Penicillin, Cephalosporins). Protein synthesis (30S): Aminoglycosides, Tetracyclines. Protein synthesis (50S): Macrolides, Chloramphenicol. DNA/RNA: Fluoroquinolones, Rifampin.
What is the ABCD of antihypertensives?
A = ACE inhibitors/ARBs, B = Beta-blockers, C = Calcium Channel Blockers, D = Diuretics. This follows NICE guidelines for hypertension management step therapy.
