Split powder preparations containing ambroxol HCl, pseudoephedrine HCl, and triprolidine HCl were
frequently dispensed at a private hospital in Semarang, Central Java, Indonesia. Triprolidine HCl was reported to have a
low composition in the divided powder. Content uniformity is one of the most important characteristics of
extemporaneous formulations, especially for low-dose active ingredients. The aim of this study was to evaluate the dose
uniformity of the divided powder preparation containing ambroxol HCl, pseudoephedrine HCl, and triprolidine HCl
prepared by a pharmacist in a private hospital in Semarang, Central Java, Indonesia. In this study, the
spectrophotometric method was used in combination with the chemometric analysis to determine the drug
concentration in the divided powder. The accuracy of the models was evaluated by the highest value of the coefficient of
determination of calibration, cross-validation and validation, while the precision of the models was evaluated by the
lowest value of the mean square error of calibration, cross-validation and prediction. The selected model for each
compound was used to build predictive models for quantitative analysis. It was found that the content of ambroxol HCl,
pseudoephedrine HCl, and triprolidine HCl in the subdivided powder samples were 8.120 ± 1.167 mg, 30.142 ± 3.965 mg,
and 1.193 ± 0.221 mg, respectively. The results on the uniformity of the content did not meet the requirements, as it was
found that the coefficient of variance of these determinations was more than 5%. Surprisingly, the divided powder can
be considered as a safe and acceptable dosage form due to its wide therapeutic window.
