| 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 | 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] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
