i dissolved dimenhydrinate in distilled water and eudragit in Dichloromethane vortexed for 1 minute later emulsified in continous phase of PVA 2.5% 200ml for 90min, but it formed big aggregates, and while drying at 40 degrees its color changed like if eudragit has melted.

For o/w/o i dissolved eudragit in Ethanol:DCM 8:2 later added dimenhydrinate and vortexed for 1 min, later added magnesium stearate as a droplet stabilizer then added the emulsion dropwise in to mixture of liquid parafin and n-hexane 1:1 containing span 80 0.2ml stirring at 1000rpm at 40 degree for 1 hour
