Studies on bioadhesive granules I: granules formulated with Prosopis africana (prosopis) gum.
Prosopis gum (PG) extracted from Prosopis africana was investigated for bioadhesive delivery of theophylline (TPL). Bioadhesive granules containing TPL were formulated and the bioadhesive properties evaluated using adhesion of the granules onto a porcine intestinal mucus surface.
