|Description||Droperidol is a potent antagonist of dopamine subtype 2 receptors in the limbic system.|
Droperidol produces mild α-adrenergic blockade and peripheral vascular dilation. Droperidol has been shown to block potassium efflux in the myocardium in isolated animal ventricular myocytes, resulting in a dose-dependent delay in repolarization. Droperidol has also been shown to induce early depolarizations in isolated animal Purkinje fibers. 
|In vivo||Droperidol (0.01 mM-0.3 mM) increases in a dose-dependent fashion action potential duration (APD) without altering the other parameters in rabbit Purkinje fibers stimulated at 60 pulses/min. Droperidol (1 mM-3 mM) leads to the reversal of the prolonging effect in rabbit Purkinje fibers. Droperidol (10 mM-30 mM) produces shortening in APD at 50% repolarization concomitantly with a significant decrease in Vmax, action potential amplitude and resting membrane potential in rabbit Purkinje fibers. Droperidol exerts a dual effect on repolarization, prolongation with low concentrations with development of EADs and subsequent triggered activity in rabbit Purkinje fibers.  Droperidol (3 mg/kg, single dose) decreases dose dependently not only locomotion and rearing frequencies in the open-field but also the apomorphine effects of rats. Droperidol (3 mg/kg, long term administration) induces significant tolerance to all parameters of activity recorded in the open-field in rats. Droperidol withdrawn produces an augmented responsiveness to apomorphine-induced stereotyped behavior. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
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).
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.
