14.2 Respiratory Disorders & Therapeutics
Key Takeaways
- Separate upper airway (rhinitis, sinusitis, pharyngitis) from lower tract (bronchitis, pneumonia, asthma, COPD) before picking remedies
- Asthma differentials on AIAPGET cluster around Arsenicum, Ipecacuanha, Antimonium tartaricum, and supporting polychrests
- Pneumonia stems combine fever, rusty/blood-tinged sputum, and chest findings with Bryonia, Phosphorus, or Antimonium tart pictures
- Ipecac: incessant nausea with clean tongue and spasmodic cough; Antimonium tart: rattling mucus that cannot be expectorated
- Red-flag respiratory failure language (cyanosis, silent chest, exhaustion) outranks constitutional prescribing in triage thinking
14.2 Respiratory Disorders & Therapeutics
Quick Answer: Resolve respiratory MCQs by tract level + one decisive keynote: Arsenicum (anxious, chilly, restless, worse after midnight, warm sips), Ipecac (spasmodic cough with incessant nausea and clean tongue), or Antimonium tart (coarse rattling, cannot expectorate, drowsy-cyanotic). For pneumonia, add Bryonia (dry painful cough, worse motion) and Phosphorus (burning chest, rusty sputum, cold-drink thirst).
AIAPGET respiratory items almost always encode one physical keynote (time modality, sputum character, nausea link, rattling without expectoration) inside a short clinical stem. Your job is to diagnose the syndrome at BHMS level, then select the matching polychrest.
Respiratory Framework for Homoeopathy MCQs
| Syndrome | Clinical anchors | Typical investigations |
|---|---|---|
| Bronchial asthma | Wheeze, dyspnea, nocturnal attacks, triggers | PEFR/spirometry language, eosinophils sometimes |
| Acute bronchitis | Cough ± fever after URI | Clinical; CXR if pneumonia suspected |
| Pneumonia | Fever, pleuritic pain, rusty/purulent sputum, crackles | Chest X-ray, CBC, sputum if mentioned |
| COPD / chronic bronchitis | Long smoking/exposure history, productive cough, exertional dyspnea | CXR, spirometry |
| Allergic rhinitis / sinusitis | Sneezing, watery discharge, sinus tenderness | Clinical; eosinophils / IgE rarely |
| Pleural effusion / TB hints | Dullness, weight loss, night sweats | CXR, sputum AFB when TB framed |
Asthma & Acute Dyspnea — Diagnosis
Bronchial asthma presents with episodic wheeze, chest tightness, cough, and breathlessness, often worse at night or early morning. Triggers: allergens, cold air, exercise, infection, emotion. On exam: prolonged expiration, wheeze; in severe attack — accessory muscle use, tachycardia, speech broken into words.
Differential diagnosis of wheeze/dyspnea:
- Cardiac asthma / LV failure (orthopnea, frothy sputum, cardiac history)
- Foreign body (sudden unilateral findings in child)
- COPD exacerbation (older smoker, chronic sputum)
- Vocal cord dysfunction / anxiety hyperventilation (clear lungs, perioral tingling)
- Tropical eosinophilia / parasitic hints in some Indian exam stems
Status asthmaticus / life-threatening asthma language: silent chest, cyanosis, exhaustion, altered sensorium — recognize as emergency. Homoeopathic options may still be tested, but clinical triage comes first.
Investigations
- Peak expiratory flow / spirometry showing obstruction with reversibility
- Chest X-ray to exclude pneumothorax/pneumonia in severe or atypical cases
- Absolute eosinophil count in allergic phenotypes
- ABG only if critically ill language appears
Pneumonia, Bronchitis & COPD — BHMS Anchors
Lobar pneumonia classically: sudden fever, rusty sputum, pleuritic pain, bronchial breathing over affected lobe. Bronchopneumonia is patchier, often extremes of age. TB stems add chronic cough, hemoptysis, night sweats, weight loss, apical findings.
Acute bronchitis: cough dominant, initially dry then productive, chest clear or few rhonchi, CXR often normal.
COPD: chronic productive cough ≥3 months in 2 successive years (chronic bronchitis definition), progressive dyspnea, barrel chest language, pursed-lip breathing.
Pleural pain vs pulmonary parenchymal pain: pleuritic pain worsens with inspiration and cough; pneumonia may combine both with systemic fever.
Leading Homoeopathic Therapeutics — Respiratory Core
Asthma triad (highest yield)
Arsenicum album
- Asthmatic dyspnea with great restlessness and anxiety, chilliness
- Worse after midnight (especially 1–2 a.m. band in many texts)
- Burning in chest; wants sips of warm drinks; fear of death
- Patient sits propped up; exhaustion with restlessness (must move yet weak)
- Excellent for cardiac asthma overlap stems when anxiety + midnight aggravation dominate
Ipecacuanha
- Spasmodic cough with incessant nausea and vomiting
- Clean tongue despite nausea (classic discriminator)
- Suffocative cough; wheezing; chest feels full of phlegm yet nausea leads
- Hemorrhage tendency may appear (bright blood)
- Child or adult with cough → vomit sequence strongly suggests Ipecac
Antimonium tartaricum
- Great rattling of mucus in chest with inability to expectorate
- Drowsy, pale, sweaty; wants to be carried upright; lips cyanosed in severe cases
- Impending paralysis of lungs language in old texts — rattling + sleepiness
- Worse in evening; better sitting upright
- Contrast with Ipecac: Ant tart is rattling-drowsy; Ipecac is nausea-clean tongue
Comparative asthma table
| Remedy | Decisive pointer |
|---|---|
| Arsenicum | Midnight aggravation, anxiety, restlessness, chilliness, warm sips |
| Ipecac | Cough with constant nausea/vomiting; clean tongue |
| Ant tart | Coarse rattling, cannot raise mucus, drowsy-cyanotic |
Supporting respiratory polychrests
- Bryonia alba: dry painful cough, holds chest, worse motion, better pressure/rest; pneumonia with thirst for large quantities and irritability
- Phosphorus: burning chest, rusty/blood-streaked sputum, thirst for cold drinks that may be vomited once cold; anxiety with pneumonia/hemorrhagic tendency
- Spongia tosta: dry barking croupy cough, worse before midnight; wakes with suffocation; larynx dry — croup/asthma crossover
- Sambucus nigra: snuffles in infants; nocturnal suffocative attacks; sweat on waking
- Blatta orientalis: asthma in fat people / damp basements / after suppression of rash — often an Indian-exam favorite for obese asthmatic
- Natrum sulphuricum: asthma in damp weather, especially 4–5 a.m.; greenish expectoration; sycotic damp aggravation
- Kali carbonicum: stitching chest pains, 2–3 a.m. aggravation, bag-like upper-lid swelling — asthma/COPD stitch picture
- Carbo vegetabilis: air hunger, wants to be fanned, collapse after cough exhaustion
- Hepar sulphuris: croupy cough, extreme chilliness, sensitive to cold air; later stages with rattling when Hepar follows Spongia in some teaching sequences
- Drosera: paroxysmal whooping cough, holds sides, worse after midnight
- Rumex crispus: tickling cough from larynx/suprasternal fossa, worse cold air and uncovering, better covering mouth — dry teasing cough stems
Pneumonia Remedy Cues (MCQ Patterns)
| Picture | Lean toward |
|---|---|
| Dry painful cough, lies still, large thirst | Bryonia |
| Burning chest, rusty sputum, cold-drink thirst | Phosphorus |
| Rattling, drowsy, cannot expectorate | Antimonium tart |
| Restless anxious, burning, midnight worse | Arsenicum |
| Sudden panic with dry cough at onset | Aconite (very early stage) |
Upper respiratory quick hits
- Allium cepa: bland eye lacrimation with acrid nasal discharge (or reverse compare Euphrasia)
- Euphrasia: acrid tears, bland coryza
- Pulsatilla: thick bland yellow-green discharge, changeable, worse warm room, better open air
- Mercurius: offensive sweat/saliva, tongue imprint, night aggravation — pharyngotonsillitis
- Belladonna: sudden high fever, red throat, throbbing — early inflammatory URIs
Decision Algorithm for Exam Stems
- Identify tract level (nose/throat vs bronchi/lung parenchyma).
- Note time modality (midnight Arsenicum; 2–3 a.m. Kali carb; damp Nat sulph).
- Note sputum/rales character (rusty Phosphorus; rattling Ant tart; dry Bryonia).
- Note GI link (nausea → Ipecac).
- Note mental state (anxiety/restlessness → Arsenicum; drowsy → Ant tart).
Common traps
- Calling every nocturnal asthma Arsenicum without checking for rattling-drowsiness (Ant tart) or nausea (Ipecac)
- Mistaking cardiac asthma for pure bronchial asthma — look for frothy sputum and heart history; Arsenicum may still fit, Digitalis/Carbo veg may compete
- Treating whooping-cough paroxysms as ordinary bronchitis — Drosera/Cuprum/Belladonna clusters differ
