The main objective of this research was to develop a sustained-release suspension of cinnarizine hydrochloride using raft-forming technique. This innovative approach has been utilized to formulate a series of suspension formulations using hydroxypropyl cellulose (HPC) as a release-retardant polymeric agent. Cinnarizine sustained-release suspensions were prepared by physical mixing method with varying concentrations and combinations of HPC, sodium citrate, sodium saccharin, calcium carbonate, sodium alginate, methyl hydroxybenzoate and propyl hydroxybenzoate. The formulations were subjected for determination of floating time, floating lag time, weight of the raft, physical appearance and in-vitro dissolution. The dissolution was conducted through USP apparatus 2 (paddle type) in 0.1N hydrochloric acid medium having pH 1.2. The key findings of the study demonstrate that a stable sustained-release suspension of cinnarizine can be formulated using raft-forming approach for increased bioavailability and patient-convenience.

A dissolution method was developed and validated for evaluation of the dissolution behavior of capsule dosage form of tramadol hydrochloride as there was no official method available. The UV spectrophotometric method developed was based on the direct estimation method using 271 nm as λmax of tramadol hydrochloride. The method was validated according to International Conference on Harmonisation (ICH) guidelines which include accuracy, precision, specificity, linearity, and analytical range. In addition, solubility and stability of the drug in dissolution medium i.e., 0.1 N HCl was studied. The established dissolution conditions were 900 mL dissolution medium at temperature 37 ± 0.5°C, using USP apparatus I at stirring rate of 100 rpm for 30 min. The corresponding dissolution profiles were constructed and all the selected brands showed more than 80% drug release with in 30 min. Thus, the proposed dissolution method can be applied successfully for the quality control of tramadol hydrochloride capsules.
