EMERGENCY DRUGS
INTRODUCTION
Emergency drugs are life-saving medications used in acute, time-critical situations such as cardiac arrest, shock, respiratory failure, poisoning, and severe metabolic disturbances. These drugs are selected based on rapid onset of action, predictable effects, and ease of administration under emergency conditions.
CARDIOVASCULAR EMERGENCY DRUGS
Adrenaline (Epinephrine)
Adrenaline is the most important drug in resuscitation and anaphylaxis management. It is an endogenous catecholamine that stimulates alpha-1, beta-1, and beta-2 receptors, making it a powerful vasoconstrictor, cardiac stimulant, and bronchodilator.
Mechanism of Action:
- Alpha-1 → vasoconstriction → ↑ blood pressure
- Beta-1 → ↑ heart rate and contractility
- Beta-2 → bronchodilation
Indications:
- Cardiac arrest (asystole, pulseless VT/VF)
- Anaphylactic shock
- Severe asthma exacerbation
Dose:
- Cardiac arrest: 1 mg IV every 3–5 minutes
- Anaphylaxis: 0.3–0.5 mg IM (1:1000)
Pharmacokinetics:
Rapid onset, short duration; metabolized by MAO and COMT.
Adverse Effects:
- Tachycardia
- Hypertension
- Arrhythmias
- Anxiety, tremors
Clinical Pearl:
First-line drug in anaphylaxis and cardiac arrest—no delay should occur in administration.
Atropine
Atropine is an antimuscarinic agent used primarily to treat symptomatic bradycardia and organophosphate poisoning.
Mechanism:
Blocks acetylcholine at muscarinic receptors → inhibits parasympathetic activity → increases heart rate.
Indications:
- Symptomatic bradycardia
- Organophosphate poisoning
Dose:
- Bradycardia: 0.5 mg IV every 3–5 minutes (max 3 mg)
Adverse Effects:
- Dry mouth
- Blurred vision
- Tachycardia
- Urinary retention
Clinical Note:
Avoid low doses—they can paradoxically worsen bradycardia.
Amiodarone
A broad-spectrum antiarrhythmic used in life-threatening arrhythmias.
Mechanism:
Blocks potassium channels → prolongs action potential and refractory period.
Indications:
- Ventricular fibrillation
- Ventricular tachycardia
Dose:
- 300 mg IV bolus in cardiac arrest
Adverse Effects:

Half-life <10 seconds
Side Effects:
- Flushing

Adverse Effects:
- Tissue necrosis (if extravasation)

Dopamine
Dose-dependent effects make dopamine versatile.
Mechanism:
