NG-100 PHARMACOLOGY ADHD-friendly visual edition

Every anti-inflammatory drug interrupts the same fire — the body's inflammatory cascade — just at a different spot and a different speed. This page is the map for the whole pain & anti-inflammatory unit: compare the 4 big families here, then go deep on NSAIDs (NG-256), Acetaminophen (NG-232), and the DMARD Sulfasalazine (NG-175) on their own pages.

📄 Simple Nursing original — opens in Drive →

🗂️ 4 families, 1 goalNSAIDs, Acetaminophen, Corticosteroids & DMARDs all fight pain/inflammation — different mechanism, different speed.

💊 Steroids = slow & broad"-sone / -lone" suffix. Days to work. NOT a rescue drug for an acute attack.

🐢 DMARDs = disease-modifyingWeeks–months onset. Used for RA and IBD (sulfasalazine does both).

🚨 The 2 must-knowsNSAID "triple whammy" nephrotoxicity + Tylenol max-dose liver toxicity — the two highest-yield NCLEX traps in this unit.

FAMILIES

STEP 1 · MEET THE FIRE

One inflammatory cascade, four different places to jump in and shut it down.

🔥 The inflammation cascade — where each family blocks it

BIG PICTURE Tissue injury releases arachidonic acid from cell membranes. The enzyme COX (cyclooxygenase) turns it into prostaglandins — the chemicals that cause pain, fever, and swelling. Every drug on this page interrupts that chain somewhere.

🧠 "Steroids block early, NSAIDs block the middle, Tylenol quiets the brain, DMARDs slow the whole loop." One sentence, four families.

📊 Compare the 4 families

GROUP MAP The single most-tested contrast: which one hurts the stomach/kidneys, which one hurts the liver, which one hurts the immune system.

Class	Example drugs	Mechanism	Best for	Key risk
NSAIDs 🔥	Ibuprofen, Naproxen, Ketorolac (Toradol), Indomethacin, Aspirin	Block COX-1 & COX-2 → ↓prostaglandins	Pain, fever, inflammation, gout, RA/OA	GI bleed · renal injury · CV risk
Acetaminophen 🧠	Tylenol	Central COX inhibition — antipyretic/analgesic, weak peripheral anti-inflammatory	Fever/pain when NSAIDs are risky (PUD, bleeding disorder, kids)	Hepatotoxicity if max dose exceeded
Corticosteroids 💊	Methylprednisolone, Prednisone, Fluticasone, Beclomethasone "-sone/-lone"	Suppress broad inflammatory & immune response — slow, genomic	Severe/chronic inflammation, asthma maintenance, autoimmune flares	Hyperglycemia, infection risk, adrenal suppression
DMARDs 🐢	Sulfasalazine, Methotrexate	Modify the underlying immune process — weeks to months onset	Rheumatoid arthritis, IBD (Crohn's/UC)	Immunosuppression · agent-specific (e.g. sulfa allergy for sulfasalazine)

🧠 "NSAID = stomach & kidney. Tylenol = liver. Steroid = sugar & infection. DMARD = the immune system itself." Match the drug family to the organ it threatens and half the NCLEX question is already answered.

🔤 Say the names — suffix clues

-sone / -lone = corticosteroid (methylprednisolone, fluticasone, beclomethasone)
-profen / -oxicam / -fenac = NSAID (ibuprofen, meloxicam, diclofenac)
-lukast = leukotriene inhibitor (montelukast, zafirlukast)
Acetaminophen has no shared suffix — it's chemically its own thing (a para-aminophenol derivative), which is exactly why it doesn't act like an NSAID.

🧠 If the drug name ends in -sone/-lone, assume slow, broad, sugar-raising before you even read the question stem.

💊

CORTICOSTEROIDS

STEP 2 · THE BROAD BLOCKER

Powerful and slow — a maintenance drug that gets mistaken for a rescue drug on exams.

💊 The "-sone / -lone" family

Drug	Route	Use
Beclomethasone	Inhaled	Asthma maintenance / prevention
Fluticasone	Inhaled (also nasal)	Asthma maintenance, allergic rhinitis
Methylprednisolone (brand: Solu-Medrol)	IV / PO — systemic	Acute flares, after the rescue inhaler in an attack

Slow onset — corticosteroids work over hours to days, not minutes. They calm swelling and inflammation broadly, but they are NOT the first drug given for the first sign of an acute attack.

🧠 "AIM" for an acute asthma attack, in order: Albuterol 1st → Ipratropium 2nd → Methylprednisolone (Solu-Medrol) — steroids come after the rescue bronchodilators, never first.

🚨 Side effects to watch

🍬 Hyperglycemia — monitor blood glucose, especially in diabetics
🦠 Oral thrush (Candida) — inhaled route; mouth sores/white patches
🧬 Immunosuppression / infection risk — systemic, long-term use
🦴 Osteoporosis — long-term systemic use
⛔ Never stop abruptly after long-term systemic use — adrenal insufficiency/crisis risk; taper down

🧠 Blood sugar UP, immune system DOWN. Picture a "-sone" pill sitting on a sugar cube while an immune cell falls asleep.

✅ Teaching — inhaled steroid technique

🔄 Use a spacer to improve delivery and cut mouth deposition
🚿 Rinse mouth after each use — spit, don't swallow the water
⏱️ Take on a scheduled, daily basis — not PRN
❌ Never use for the first sign of an acute attack — reach for the rescue inhaler (albuterol) instead

🧠 Rinse & spit, never for the fit. "Fit" = acute attack. Steroids don't touch an attack already happening.

🫁

PREVENTER RX

STEP 3 · PREVENT, DON'T RESCUE

Two more anti-inflammatory classes that only work if taken before the trigger — never during.

🧪 Leukotriene inhibitors — "-lukast"

Montelukast, Zafirlukast (brand: Singulair).

🧠 "Luke likes to SING (airway open)." Montelukast keeps the airway singing — but only if taken every day, not as a rescue drug during an attack.

🧪 Mast cell stabilizers — Cromolyn

Blocks mast cell degranulation → prevents the release of histamine and inflammatory mediators before they start.

🧠 Cromolyn = the sunscreen of asthma drugs. Sunscreen only works if applied before sun exposure — cromolyn only works if taken before exercise.

🚫 Never confuse: RESCUE vs. PREVENTER

🚑 Rescue — during an attack	🛡️ Preventer — before it starts
Albuterol — fast-acting bronchodilator, first drug given	Inhaled corticosteroids, leukotriene inhibitors, mast cell stabilizers — daily or pre-exposure only
Works in minutes	Works over hours to weeks — will not stop an attack already happening

🧠 If the NCLEX stem says "first sign of an acute attack" — the answer is always the rescue drug, never a "-sone," "-lukast," or Cromolyn.

QUICK RECALL

SAY IT OUT LOUD

🗂️ 4 familiesNSAIDs · Acetaminophen · Corticosteroids · DMARDs — each blocks the fire at a different point

💊 "-sone/-lone"= corticosteroid = slow, broad, sugar-raising, NOT a rescue drug

🛡️ Preventers only work BEFORELeukotriene inhibitors + mast cell stabilizers — never during an attack

🚨 Deep dives nextNSAIDs, Acetaminophen & Sulfasalazine each get their own page in this unit

🎯 Cover & check — 4 rapid-fire questions

Q1: Which anti-inflammatory family has the slowest onset and works "upstream" in the inflammatory cascade?

Corticosteroids ("-sone/-lone") — they block inflammation broadly and take hours-to-days to work; never the first drug for an acute attack.

Q2: A client is having their first sign of an acute asthma attack. What order do drugs get given?

AIM — Albuterol 1st, Ipratropium 2nd, Methylprednisolone (Solu-Medrol) last.

Q3: Which drug family is dosed specifically to prevent exercise-induced bronchospasm, taken 10–15 minutes before activity?

Mast cell stabilizers, e.g. Cromolyn.

Q4: Which family is used for both rheumatoid arthritis and inflammatory bowel disease, with onset measured in weeks-to-months?

DMARDs (disease-modifying antirheumatic drugs) — e.g. sulfasalazine, methotrexate.
