ABSTRACT
Floating drug delivery systems (FDDS) are the drug delivery systems having a bulk density lower than the gastric content and they remain buoyant in the stomach for a prolonged period of time, with the potential for continuous release of drug. Cinnarizine, a H1-receptor antagonist, used for the treatment for vestibular vertigo disorders and motion sickness was selected as the drug aspirant and Gelucire 43/01 was selected as a lipid carrier in different ratio (1:0.5, 1:1, 1:1.5) along with drug to be formulated as gastro retentive multiparticulate system. The formulation F1 to F9 were prepared and formulation F4 to F9 were evaluated for in-vitro drug release and formulation F5 was selected as optimized formulation that exhibited good floating ability and zero order drug release (93.56 %) at the end of 8 hrs. The in-vitro drug release study of the aged sample show phase conversion of Gelucire. The phase conversion also caused increase in drug release. In conclusion, hydrophobic lipid, Gelucire 43/01 can be considered as an effective carrier for design of a multiple unit floating drug delivery system of cinnarizine.
