Abstract:Objective To explore the preparation parameters of aripiprazole oral solution through different evaluation indicators and determine the optimal preparation process.Methods A comparative study was conducted by selecting reference formulations to investigate the key process parameters affecting the preparation of aripiprazole oral solution. The determined process parameters were used for sample preparation, and the influencing factors of the reference formulation and self-made formulation were simultaneously investigated. Key items were tested for quality evaluation.Results There were no significant differences in content, related substances, pH value, etc. between the homemade formulation and the reference formulation under the influencing factors.Conclusion The small-scale preparation process of aripiprazole oral solution is reasonable and can provide supporting evidence for later batch scaling up.
