Evaluation of proteolytic enzymes in effervescent tablets

Area of Science:

• Analytical Chemistry
• Pharmaceutical Sciences
• Enzymology

Background:

• Effervescent tablets often contain high salt concentrations and chromophores, which can interfere with analytical assays.
• Accurate quantification of active pharmaceutical ingredients (APIs), such as proteolytic enzymes, is crucial for drug product quality and efficacy.
• Existing methods may struggle to provide reliable results for complex formulations like effervescent tablets.

Purpose of the Study:

• To develop and validate a robust analytical procedure for evaluating proteolytic enzyme activity in effervescent tablet formulations.
• To address and overcome the analytical challenges posed by excipients commonly found in effervescent tablets.

Main Methods:

• A two-step analytical approach combining chromatography with enzymatic activity assays was employed.
• High-performance liquid chromatography (HPLC) was utilized to separate and remove interfering substances.
• Subsequent enzymatic assays were performed on the purified enzyme fraction to determine activity.

Main Results:

• The developed chromatographic method effectively separated proteolytic enzymes from high salt content and chromophoric interferences.
• The enzymatic activity assay, applied after chromatographic purification, yielded accurate and reproducible measurements of enzyme levels.
• The procedure demonstrated suitability for routine quality control of proteolytic enzymes in effervescent tablets.

Conclusions:

• The reported procedure provides a reliable method for the quantitative evaluation of proteolytic enzymes in effervescent tablets.
• This method successfully mitigates interferences from formulation components, enhancing analytical accuracy.
• The validated technique is suitable for pharmaceutical quality control and research involving these complex dosage forms.
