Abstract EN
Vancomycin HCl was prepared as orally administered colon target drug delivery tablets for systemic therapy.
Tablet matrices containing 10–60% of tablet weight of guar gum (F1–F6) were prepared by direct compression and subjected to in vitro release studies to explore their sustained release in the colon.
Various synthetic and natural polymers were incorporated to F6 to modify the drug release rate.
Different 15 matrix tablet formulations (F6–F20) were enteric coated with hydroxypropyl methyl cellulose phthalate.
F6, F13 and F20 showed promising sustained release results having median dissolution time (MDT) values: 8.25, 7.97, and 7.64, respectively.
Microbiological assay was performed to test the efficacy of F6, F13, and F20 to inhibit clinical Staphylococcus aureus (SA) isolates.
Bactericidal activity of F6 was reached after 2, 4, and 24 hours of incubation against MSSA 18, MRSA 29, and MRSA 11 strains, respectively, while it was reached within 6–8 hours in case of F13, and F20 against all strains tested.
F13 enhanced log microbial reduction by 1.74, 0.65 and 2.4 CFU/mL compared to F6 while it was 1, 2.57 and 1.57 compared to F20 against MSSA18, MRSA11 and MRSA29, respectively.
Vancomycin HCl tablets displayed a promising sustained release in vitro and microbiological inhibitory action on all isolates tested.
