Background and purpose: Solubility plays an important role in bioavailability of drugs. Any
alter can cause changes in the physical and chemical properties of the drug release and consequently,
changes in the bioavailability of the drug. It is necessary to recognize the best storage conditions to
achieve desired drug release.
Material and Methods: Carbamazepine tablets containing different ratios of polyethylene
glycol and Precirol were prepared by direct compression method. The tablets were then placed in various
temperatures and humidity for 6 months. Carbamazepine release was investigated from formulations and
the data was processed with kinetic models. DSC and FTIR method was used to determine the physical
stability of tablets.
Results: The results of drug release from various formulations at zero time, 3 and 6 months
showed significant differences in formulations containing PEG. The thermogram did not show any
interaction between drug and excipients.
Conclusion: Statistical studies of dissolution data revealed that storing carbamazepine tablets in
different situations can cause significant changes in drug release profile. No changes were observed in the
physical stability of the tablets.
