Abstract
Introduction: Multi-particulate dosage form of pellet is formed by agglomeration of fine powdered drugs and excipients, leading to free flowing spherical particles. The multi-step process of extrusion & spheronization are mostly applied for preparation of uniformly-sized pellets. Golqand, a product of Traditional Persian Pharmacy containing Rosa damascena Mill petals is a heart and brain tonic, refresher, astringent, and a stomachic. It helps to improve appetite and relieves digestive diseases. Also, Golqand calms down nervous system. Based on traditional texts, it has been produced as a Jam-like preparation, imposing some difficulties in taking and dosing. In this study, we have prepared Golqand in pellet form, a novel solid dosage form and optimized this natural formulation.
Methods and Results: In this study, a 20 runs D-optimal method was applied as an experimental design to establish the optimum conditions for Golqand pellet preparation by extruder spheronizer equipment. The preparation process of pellets was optimized by a systematic multi-objective-optimization approach in terms of D- values for the particle size distribution (i.e. D10, D50 & D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass obtained via sieving method.
The Model F-value of 6.58 implied the models were significant. There is only a 0.34% chance that a "Model F-Value" this large could occur due to noise. The R2, adjusted R2, predicted R2, and adequate precision for D50 model were calculated 82%, 72%, 46%, and 10.06, respectively which means that there is a good correlation between parameters and model.
Conclusions: In conclusion, presented models conducted us to prepare Golqand pellets with unimodal particle size distribution and pre-defined particle size. Applying pelletization method for Golqand preparation could resolve some critical challenges of natural formulations like taking similar doses.
