This study developed chewable gels with nanoparticulate praziquantel, showing promising results for drug delivery. These gels offer improved dissolution and can be applied to other poorly soluble drugs.
Area of Science:
- Pharmaceutical Technology
- Drug Delivery Systems
- Materials Science
Background:
- Chewable gels offer advantages over conventional dosage forms but require further development.
- Incorporating drugs in nanoparticulate form presents a novel approach for enhanced bioavailability.
Purpose of the Study:
- To develop and characterize chewable gel formulations containing nanoparticulate praziquantel.
- To assess the impact of gelatin concentration and drug incorporation method on formulation properties.
- To evaluate the in vitro dissolution performance of the developed chewable gels.
Main Methods:
- Six chewable gel formulations were prepared with varying gelatin concentrations and praziquantel incorporation methods.
- Formulations were characterized for moisture content, water activity, pH, drug content, texture, and disintegration time.
- In vitro dissolution studies were conducted to compare the release profiles of different formulations.
Main Results:
- Physicochemical properties (moisture, pH, drug content) were within acceptable ranges for chewable gels.
- Gelatin concentration and praziquantel incorporation significantly influenced texture and disintegration.
- Chewable gels with nanoparticulate praziquantel demonstrated improved in vitro dissolution compared to conventional forms.
Conclusions:
- Nanoparticulate drug incorporation is feasible and beneficial for chewable gel formulations.
- These semisolid formulations show potential for delivering other low-aqueous solubility drugs.
- Further research can optimize chewable gel formulations for enhanced therapeutic efficacy.
