|Description||Levodropropizine possess anti-allergic and inhibits histamine receptor, reduces cough by interfering with stimulus activation of peripheral endings of sensory nerves and by modulation of neuropeptides involved in the cough reflex.|
|Features||Demonstrates a better tolerability index than the Racemate.|
Levodropropizine has affinity for H1-histaminic and alpha-adrenergic receptors. 
|In vivo||Levodropropizine has weaker central sedative effects than the racemate and it does not induce physical dependence in rats.  Levodropropizine (15 mg/kg, i.v.) reduces both the duration of apnoea and the response of the C-fibre to phenylbiguanide. The LVDP-induced inhibition of the C-fibre response to PBG is on average 50% in pulmonary and 25% in non-pulmonary fibres.  Levodropropizine is shown to have good antitussive activity in anaesthetized guinea-pigs and rabbits. Levodropropizine (i.v.) is 1/10 to 1/20 as active as codeine and comparable to dropropizine on mechanically and electrically induced coughing in rabbits and guinea-pigs. Levodropropizine (orally) is comparable with those of both dropropizine and codeine against coughing induced by irritant aerosols.  Levodropropizine (40 μg/50 μL i.c.v.) does not prevent electrically-induced cough, while Codeine (5 μg/50 μl i.c.v.) markedly prevents coughing in guinea-pigs. Levodropropizine has a peripheral site of action which is related to sensory neuropeptides.  Levodropropizine (10 mg/kg, 50 mg/kg and 200 mg/kg) reduces in a dose-dependent manner the extravasation of Evans blue dye evoked by capsaicin in the rat trachea. Levodropropizine (200 mg/kg) inhibits also substance P-evoked extravasation, whereas it does not affect the extravasation evoked by platelet activating factor. |

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.
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.
