Development and Dissolution Study of a β-Galactosidase Containing Drinking Straw

Area of Science:

• Pharmaceutical Sciences
• Drug Delivery Systems
• Pediatric Formulations

Background:

• Pharmaceutical formulation development requires consideration of patient adherence alongside physicochemical properties.
• Medicated drinking straws represent an innovative approach to improve pediatric medication administration and compliance.
• Rapid disintegration particles are a key component for effective straw-based delivery systems.

Purpose of the Study:

• To prepare lactase-containing, rapid disintegration particles using standard pharmaceutical techniques.
• To evaluate the in vitro dissolution rate of medicated drinking straws under varying conditions.
• To investigate the influence of liquid temperature and administration frequency on drug release from the straw formulation.

Main Methods:

• Preparation of rapid disintegration particles containing lactase via two common pharmaceutical industry techniques.
• In vitro simulation of medicated drinking straw usage to assess patient-relevant administration.
• Dissolution rate testing under varied liquid temperatures and administration frequencies.

Main Results:

• Successfully prepared lactase-containing, rapid disintegration particles suitable for medicated straws.
• Demonstrated that both the temperature of the administration liquid and the frequency of straw use significantly affect the dissolution rate.
• The release rate of the active ingredient from the formulation is highly dependent on these administration parameters.

Conclusions:

• Medicated drinking straws are a viable and innovative dosage form for pediatric applications.
• Optimizing liquid temperature and administration frequency is crucial for controlling drug release from rapid disintegration particles in straws.
• These findings provide valuable insights for the development and effective use of medicated straw formulations.
