Doxapram is a powerful respiratory stimulant drug used in emergency medicine to activate breathing when respiration becomes dangerously slow or depressed. It plays an important role in anesthesia recovery and critical care settings.
What is Doxapram?
Doxapram is a central nervous system (CNS) stimulant that primarily stimulates the respiratory center in the brain.
Class: Respiratory stimulant / Analeptic
Route: Intravenous (IV) or infusion
Action: Increases rate and depth of breathing
Mechanism of Action
Doxapram works through dual stimulation:
Stimulates carotid body chemoreceptors
Activates medullary respiratory center
This results in:
Increased respiratory rate
Enhanced tidal volume
Improved oxygenation
Therapeutic Uses
Post-anesthetic respiratory depression
Drug-induced respiratory depression
Acute respiratory failure (selected cases)
COPD patients with ventilatory insufficiency
Neonatal apnea (historical/limited use)
Pharmacological Effects
Rapid onset of action
Short duration effect
Improves ventilation without mechanical assistance
Raises arterial oxygen levels
Adverse Effects
Restlessness
Hypertension
Tachycardia
Sweating
Seizures (high doses)
Contraindications :
Epilepsy or seizure disorders
Severe hypertension
Head injury or cerebral pathology
