IR spectroscopic studies indicated that the drug is
compatible with all the excipients. The IR spectrum
of CP1 showed all the characteristic peaks of MTH
pure drug, thus confirming that no interaction of
drug occurred with the components of the
formulations. Short-term stability studies of the
above formulations indicated that there are no
significant changes in drug content and in vitro
dispersion time at the end of 3 months period
