Abstract: (48 Views)
Background The evaluation of drug-excipient incompatibility is a crucial step in pre-formulation studies, as drug-excipient interaction can have an impact on drug stability and bioavailability. The right selection of excipients is the key to developing successful drug delivery systems or dosage forms. This study is focused on assessing amoxicillin-lactose incompatibility reactions in the solid state through physicochemical techniques.
Methods The mixture of amoxicillin and lactose was made in a 1:1 mass ratio, added to 20% (w/v) water, and kept in closed vials at 60°C. The direct compression method was utilized to prepare amoxicillin, amoxicillin-lactose, and lactose tablets. The manufactured tablets were stored at a temperature of 60°C. Finally, amoxicillin-lactose incompatibility in the solid state was analyzed by Fourier Transform Infrared and differential scanning calorimetry methods over 4 weeks.
Results Physicochemical methods, including differential scanning calorimetry, Fourier Transform Infrared spectroscopy, and visual observation, confirmed incompatibility between amoxicillin and lactose.
Conclusion It is concluded that using lactose in solid pharmaceutical preparations of amoxicillin will result in compatibility problems.
