چکیده (انگلیسی):

The aim of this study was to optimize and formulate fast disintegrating tablets (FDTs) for
nausea and vomiting using aminoacetic acid, carmellose and sodium alginate with enough mechanical
strength. Ondansetron HCl (water soluble) or domperidone (water insoluble) drug were added to FDTs
and their disintegration behaviour was evaluated. Plackett Burman Screening Design was used to screen
the independent active process variables [concentration of aminoacetic acid (X1), concentration of
carmellose (X2) and tablet crushing strength (X3)] which were found to actively influence the dependent
variables [disintegration time in the mouth (DT), wetting time (WT), and water absorption ratio (WAR)]
for both the drugs. Also, the coefficients of active variables (DT, WT and WAR) of FDTs containing
domperidone was found to be significantly different (P<0.05) from the coefficients of active factors (X1,
X2 and X3) containing ondansetron HCl FDTs. Further, FDTs containing domperidone was prepared
according to central composite design for estimating the effect of active factors (X1, X2, X3) in extended
spherical domain. The regression analysis of quadratic fit revealed that DT, WT and WAR were 98%
correlated with active factors (X1, X2 or X3). The optimized domperidone FDTs were further compared
with superdisintegrants (croscarmellose sodium or crospovidone). The data revealed that optimized
domperidone FDTs were better than domperidone FDTs containing croscarmellose or crospovidone.
Hence, this novel excipients combination can be used for delivery of water insoluble drugs in place of
superdisintegrants.
