Indications

Condition Typical Use

Allergic rhinitis (seasonal or perennial) Reduce nasal congestion, rhinorrhea, sneezing, itching; used as first‑line therapy for moderate‑to‑severe symptoms.

Asthma related to allergies (as part of an overall management plan) Adjunctive treatment when asthma is triggered by allergens.

Allergic conjunctivitis (when co‑present with rhinitis) Reduces ocular itching and redness.

> Note: Use in children under 12 years requires careful dosing; many formulations are approved for use down to age 2 or 6 depending on the product.*

3. How it Works – The Pharmacology

Drug class Key drug (generic) Primary target & mechanism

Corticosteroid Prednisolone, dexamethasone, mometasone Binds glucocorticoid receptor → translocation to nucleus → up‑regulates anti‑inflammatory genes and down‑regulates pro‑inflammatory cytokines (IL‑1β, TNF-α). Inhibits phospholipase A2 → ↓ arachidonic acid → ↓ prostaglandins & leukotrienes.

Antihistamine Diphenhydramine, cetirizine, loratadine H1‑receptor antagonism → blocks histamine‑mediated vasodilation and capillary permeability.

3. How the drugs affect the inflammatory cascade

Step of inflammation Effect of drug

Early release of histamine (mast cell degranulation) Antihistamine blocks H1 receptors → ↓ edema, itching

Vascular tone & permeability Antihistamine and antihypertensives reduce vasodilation; antihistamine also reduces capillary leak

Neutrophil recruitment & activation No direct effect; but reduced vascular leakage limits neutrophil influx

Pro‑inflammatory cytokines (TNF‑α, IL‑1β) Not directly inhibited by these drugs

Late-phase inflammation Antihistamine less effective; other anti-inflammatory agents may be needed

4. How a Vascular Endothelial Cell Responds to These Drugs

Drug Receptor / Target on EC Signal Transduction (typical) Cellular Outcome

Aspirin COX‑2 (enzyme, not receptor). Inhibition of prostanoid production. ↓ PGE₂ → ↓ EP2/EP4 activation → ↓ cAMP. Reduced vascular permeability; decreased expression of adhesion molecules; lower leukocyte recruitment.

Ibuprofen / Naproxen Same as aspirin: inhibit COX‑2. Same pathway. Similar anti‑inflammatory effects.

Diclofenac COX‑2 inhibition. Same. Anti‑inflammatory, decreased cytokine production.

Ketorolac COX‑1/COX‑2 inhibition. ↓ PGE₂ → ↓ EP signaling. Decrease in pain and inflammation; possible mild effects on platelet function (COX‑1).

Meloxicam Selective COX‑2 inhibition. ↓ PGE₂ → ↓ EP signaling. More targeted anti‑inflammatory, less GI toxicity.

5. Summary of Mechanisms

Drug Class Primary Target(s) Resulting Effect on Pain/Inflammation

NSAIDs / COX inhibitors Cyclooxygenase (COX‑1 & COX‑2) ↓ prostaglandins → ↓ vasodilation, vascular permeability, nociceptor sensitization → reduced pain and swelling.

Steroids Glucocorticoid receptor → transcriptional changes; inhibition of NF‑κB, COX‑2, PLA₂, etc. ↓ cytokine production, leukocyte migration, prostaglandin synthesis → dampened inflammation and edema.

Practical Take‑away for your situation

If you need rapid reduction of swelling: a short course of a systemic steroid (e.g., prednisone 30–40 mg daily for 3–5 days) is often used in clinical practice for severe soft‑tissue inflammation, provided no contraindications exist.

For chronic management or to avoid steroids: topical NSAIDs (diclofenac gel) can help reduce pain and inflammation locally. Adding a short course of oral ibuprofen may provide additional anti‑inflammatory benefit while minimizing systemic steroid exposure.

Monitoring: if you use any medication, keep an eye on blood pressure and watch for signs of infection (fever, increased pain). If the swelling worsens or new symptoms appear, seek medical attention promptly.

Bottom line

You can treat a swollen, painful arm with NSAIDs such as ibuprofen (or naproxen) taken every 6–8 h up to 3 days; if you want faster relief and fewer stomach side‑effects, use acetaminophen + a topical NSAID gel.

If pain is severe or swelling persists beyond a few days, add an oral steroid such as prednisone for short course (e.g., 5 mg daily for 2–3 days).

Always consider any existing medical conditions or medications you’re on; if in doubt, consult your healthcare provider or pharmacist before starting new medication.
