Biological Activity: Doxapram hydrochloride hydrate is a respiratory stimulant. Doxapram hydrochloride hydrate increases breathing rate and depth by acting on the brain's respiratory centers and peripheral chemoreceptors. Doxapram hydrochloride hydrate inhibits TASK-1, TASK-3, TASK-1/TASK-3 heterodimeric channel function with EC50s of 410 nM, 37 μM, 9 μM, respectively. Doxapram hydrochloride hydrate inhibits the Ca²⁺-activated potassium current (IC50 ≈ 13 μM) and Ca²⁺-independent potassium current (IC50 ≈ 20 μM) in type I cells of the carotid body. Doxapram hydrochloride hydrate significantly prolongs the effective refractory period of the atrium and has an anti-arrhythmic effect. Doxapram hydrochloride hydrate can be used for the study of respiratory depression such as post-anesthesia respiratory depression, chronic obstructive pulmonary disease and apnea of prematurity[1][2][3][4][5][6].
