Description:
Background: Excipients are used in the formulation of pharmaceutical dosage forms, but may
interact with active pharmaceutical ingredients (APIs). Some of these interactions could alter
the physicochemical properties of the APIs which can affect the therapeutic efficacy and safety.
Acarbose is an anti-diabetic drug used in this study as an API to investigate its compatibility with
common excipients in order to development of pharmaceutical controlled release formulations.
Methods: For this purpose, 15 different excipients were selected. Binary mixtures of drug with
each of the excipients (1:1 mass ratio) were prepared. Mixtures were analyzed immediately after
mixing and also after incubation at stress conditions (adding 20% water and incubated at 40°C
for 2 months). The thermal analytical investigation like differential scanning calorimetry (DSC),
Fourier transform infra-red spectroscopy (FTIR) and high-performance liquid chromatography
(HPLC) were employed for physicochemical evaluations of the possible incompatibility.
Photodiode-array (PDA) and mass studies were performed to ensure the peak purity of the
HPLC peaks of API in stressed samples.
Results: Incompatible excipients with acarbose were determined as EC (ethyl cellulose),
Carbopol 934, Hydroxypropyl cellulose, PEG2000 (Polyethylene Glycol 2000), Mg Stearate, Na
Alginate and Poloxamer.
Conclusion: Results of this study would be used for the development of controlled release
formulation of acarbose. It is recommended to avoid the use of incompatible excipients
