ABSTRACT
In the present work the attempt was made to prepare taste masked suspension of Ambroxol
Hydrochloride by abating the intensely bitter taste of Ambroxol Hydrochloride. Taste abatement was
done by complexing of Ambroxol hydrochloride with different Ion Exchange Resins (IER) like Tulsion
335 and Indion 214 in different ratios. The prepared suspensions were evaluated for taste, drug
content, particle size, viscosity, sedimentation volume and drug release. The resonates prepared with
drug- T335 ratio (1:2) at pH 8, gave maximum drug loading. Suspension containing above resinates
showed more than 80% In vitro drug release within 30 min. Prepared formulation also showed good
stability and can retain its palatable taste. The developed formulation was an additional advantage like
simplification of manufacturing procedure and is economical. Thus, the “patientfriendly dosage form” of
bitter drugs, especially for pediatric, geriatric, bedridden, and noncooperative patients, can be
successfully formulated using this technology.
KEYWORDS: AHS, Formulation, IER, Taste masking.
