Description

Doxapram HCl inhibits TASK-1, TASK-3, TASK-1/TASK-3 heterodimeric channel function with EC50 of 410 nM, 37 μM, 9 μM, respectively.

Targets

TASK-1 ^[1]	TASK-1/TASK-3 heterodimeric ^[1]	TASK-3 ^[1]
410 nM(EC50)	9 μM(EC50)	37 μM(EC50)

In vitro
In vitro	Doxapram inhibits both TASK-1 and TASK-3 function in a dose dependent manner. Doxapram inhibition at both hyperpolarized and depolarized potentials, as well as effects independent of extracellular potassium concentration. It is said that the carboxy terminal domain of TASK-1 is important to doxapram inhibition. Doxapram also inhibits TRESK, TASK-2, and TREK-1 but at significantly larger concentrations (EC50s of 240 μM, 460 μM, and >1 mM, respectively). Doxapram has no effect on MAC for halothane. ^[1]

In Vivo
In vivo	Doxapram is an analeptic agent. The respiratory stimulant action is manifested by an increase in tidal volume associated with a slight increase in respiratory rate. A pressor response may result following Doxapram administration. The mean half-life is 3.4 h (range 2.4-4.1h), the mean apparent volume of distribution is 1.5 mg/kg and the whole body clearance is 370 mL/min. Enteric-coated capsules of doxapram base are absorbed rapidly after an initial delay, and the systemic availability is about 60%.^[2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
