Phenylalanine-free taste-masked orodispersible tablets of fexofenadine hydrochloride: development, in vitro evaluation and in vivo estimation of the drug pharmacokinetics in healthy human volunteers.
Abstract CONTEXT: Fexofenadine hydrochloride (FXD) is a slightly soluble, bitter-tasting, drug having an oral bioavailability of 35%. The maximum plasma concentration is reached 2.6 h (T(max)) post-dose. OBJECTIVE: Developing taste-masked FXD orodispersible tablets (ODTs) to increase extent of drug absorption and reduce Tmax. METHODS: Taste masking was achieved via solid dispersion (SD) with chitosan (CS) or […]
