Levodropropizine

Synonyms: (S)-(-)-Dropropizine,DF-526

Levodropropizine((S)-(-)-Dropropizine,DF-526) 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.

Levodropropizine has weaker central sedative effects than the racemate and it does not induce physical dependence in rats. [1] 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. [2] 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. [3] 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. [4] 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. [5]

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.
