Doxapram hydrochloride (marketed as Dopram®) is a respiratory stimulant. Administered intravenously, doxapram stimulates the respiratory rate, leading to an increase in tidal volume.
Mode of action
Doxapram stimulates chemoreceptors in the carotid arteries, which in turn, stimulates the respiratory centre in the brain stem.
Doxapram is a white to off-white, odorless, crystalline powder that is stable in light and air. It is soluble in water, sparingly soluble in alcohol and practically insoluble in ether. Injectable products have a pH from 3.5-5. Benzyl alcohol or chlorobutanol is added as a preservative agent in the commercially available injections.
Doxapram is used in intensive care settings to stimulate the respiratory rate in patients with respiratory failure.
High blood pressure, panic attacks, tachycardia (rapid heart rate), tremor, sweating and vomiting may occur. Convulsions have been reported. It cannot be used in patients with coronary heart disease, epilepsy and high blood pressure. It is also contraindicated in newborns and small children, mainly due to the presence of benzyl alcohol.
