ABSTRACT

OBJECTIVE:

Development of dosage form comprising of Capecitabine loaded carbon nanotubes for its targeted delivery to the colon.

METHOD:

Single walled carbon nanotubes (SWCNT) were functionalized by -COOH and Chitosan along with Folic acid. Capecitabine was loaded in these SWCNT's, and the system was analyzed by FTIR, SEM and Raman spectroscopy. Percent drug loading was assessed and the cytotoxicity (COLO320DM and HT29) was verified by using MTT and SRB assay. The apoptosis study was carried out by flowcytometry. The system was enclosed in an enteric coated capsule with pH sensitive polymers and characterized for invitro disintegration, dissolution and invivo roentgenographic studies.

RESULTS:

FTIR, Raman and XRD studies indicated the confirmation of attachments, whereas SEM exhibited size range of 200-500 nm. Drug loading capacity was observed to be 94.63 ± 1.07%. Cytotoxicity studies of Capecitabine and FA-CHI-F-SWCNT-Capecitabine against COLO320DM by using MTT assay showed that FA-CHI-F-SWCNT- Capecitabine exhibited 86.45 ± 0.5788% inhibition whereas pure Capecitabine showed 50.52 ± 0.3106% inhibition. Against HT29, the % inhibition was observed to be 82.76 ± 0.4668% and 56.41 ± 0.2316% respectively for FA-CHI-F-SWCNT-Capecitabine and pure Capecitabine. In case of SRB assay of COLO320DM, the FA-CHI-F-SWCNT-Capecitabine exhibited 89.62 ± 0.4095% inhibition and Capecitabine showed 84.36 ± 0.2559% inhibition, whereas against HT29, FA-CHI-F-SWCNT-Capecitabine showed 81.36 ± 0.2958% inhibition and Capecitabine exhibited 90.62 ± 0.4196% inhibition.

CONCLUSION:

FA-CHI-F-SWCNT loaded system revealed better cytotoxicity as compared with pure Capecitabine against two different cell lines. Invivo studies revealed that the prepared capsule formulation remained intact in the stomach thereby preventing drug release in the gastric milieu.
