Formulation and in-vitro evaluation of floating capsules of Loratadine
ABSTRACT:
The present work focuses on the development of
hydrodynamically balanced delivery system of loratadine as a single unit
floating capsules. Sustained release floating capsules for loratadine were
fabricated using drug:polymer ratio of 1:4. The hydrocolloids were used in
different proportions using 32 full factorial design and formulations were
prepared. These formulations were optimized on the basis of buoyancy, matrix
integrity, duration of floating and in vitro drug release. All the nine
formulations showed good buoyancy and matrix integrity. The duration of
floating was more than 12 h for all formulations. In vitro drug release study
of these formulations indicated controlled release of loratadine and about 90
percent drug was released at the end of 12 h.
