Summary of article contents:
1) Introduction
The study focuses on the formulation and evaluation of diclofenac sodium matrix tablets utilizing Vigna mungo seed gum as a novel natural polymer. The primary goal was to create a controlled drug delivery system that releases diclofenac sodium in a sustained manner through a well-mixed composite of the active ingredient and a hydrophilic gelling agent. The research underscores the importance of sustained release and controlled drug delivery systems in improving therapeutic outcomes and patient compliance, especially for drugs with shorter life spans.
2) Matrix System and Drug Release
Controlled Release Mechanism
Matrix tablets serve as a significant drug delivery method that provides a consistent and prolonged release of medication. The study highlights how matrix systems, particularly those based on natural polymers like Vigna mungo gum, can mimic zero-order release kinetics, which is essential for maintaining stable plasma drug levels. This characteristic is particularly valuable for non-steroidal anti-inflammatory drugs (NSAIDs) like diclofenac, which are used for various painful conditions. The results indicated that increasing the concentration of Vigna mungo gum led to a decrease in the drug release rate, thereby demonstrating its potential as a viable alternative to traditional polymers such as Hydroxypropylmethylcellulose (HPMC).
3) Phytochemical and Physicochemical Properties
Characterization of Vigna Mungo Gum
Phytochemical characterization of the isolated Vigna mungo gum revealed the presence of carbohydrates, mucilage, and polysaccharides while confirming the absence of proteins and alkaloids. Various tests, including Ruthenium red testing and Fehling’s test, demonstrated the gum's properties, confirming its suitability for pharmaceutical applications. Additionally, physicochemical characterization showed that the isolated gum is free-flowing, with good solubility in water, which is necessary for effective matrix tablet formulation. This thorough characterization underscores the gum's potential as a natural excipient in sustained release formulations.
4) Drug Loading and Performance Evaluation
Formulation and Dissolution Studies
The matrix tablets were prepared through a wet granulation technique using varying concentrations of Vigna mungo gum and starch. Evaluation parameters such as hardness, friability, and in vitro drug release were meticulously analyzed for different formulations. The findings indicated that the optimized formulation (F2) demonstrated a significant drug release of 95.03% over 12 hours. Moreover, post-compression evaluations revealed that the tablets exhibited acceptable mechanical properties and compliance with pharmaceutical standards. These results validate the use of Vigna mungo seed gum as a suitable matrix forming agent.
5) Conclusion
The study concludes that Vigna mungo seed gum possesses substantial potential as a matrix forming agent for sustained release diclofenac sodium tablets. The natural gum demonstrated comparable efficacy to conventional polymers like HPMC while being significantly cost-effective, making it a promising alternative in pharmaceutical formulations. With roughly 18% gum yield from seeds, Vigna mungo not only provides an abundant and economical resource but also serves as a foundation for future research into its applications in various drug delivery systems. The research establishes Vigna mungo seed gum as a viable natural excipient, encouraging further exploration in sustainable pharmaceutical practices.
