Optimizing Herbal Lozenges: Formulation Techniques and Efficacy Evaluation

This study presents the formulation of herbal lozenges using a heating and congealing technique. A thorough literature review informed the selection of excipients, which included Agar, Acacia, peppermint oil, citric acid, glycerin, PEG 1000, and PEG 8000. The lozenges were evaluated for weight variation, hardness, thickness, friability, disintegration time, and drug content, with all parameters meeting standard limits. Among the formulations, F6 demonstrated the highest drug content at 99.35%. The study concluded that the herbal lozenges, particularly those incorporating agar and acacia, are a promising therapeutic option for treating mouth and throat infections and enhancing immunity in patients. Stability studies were also conducted to ensure the formulation's viability.
