Title
(EN) PHENYLPHRINE PULSED RELEASE FORMULATIONS AND PHARMACEUTICAL COMPOSITIONS
(FR) FORMULATIONS ET COMPOSITIONS PHARMACEUTIQUES À LIBÉRATION PULSÉE DE PHÉNYLÉPHRINE
Abstract
(EN)
The invention discloses a pulsed-release formulation or a pharmaceutical composition comprising phenylephrine. The pharmaceutical composition comprises an immediate-release component and an enteric-coated component formulated together either in solid form or in a suspension. The enteric-coated component comprises microcrystals seeded with phenylephrine as an active ingredient and coated with a pH sensitive coating to delay release of the phenylephrine. The pharmaceutical composition can further comprise at least one active selected from the group consisting of an antihistamine, an analgesic, anti-pyretic, non-steroidal anti-inflammatory and mixtures of two or more said actives.
(FR)
La présente invention concerne une formulation ou une composition pharmaceutique à libération pulsée comprenant de la phényléphrine. La composition pharmaceutique comprend un composant à libération immédiate et un composant à enrobage entérique formulés conjointement sous forme solide ou dans une suspension. Le composant à enrobage entérique comprend des microcristaux ensemencés avec de la phényléphrine en tant que substance active et enrobés avec un enrobage sensible au pH pour retarder la libération de la phényléphrine. La composition pharmaceutique peut comprendre en outre au moins une substance active choisie dans le groupe constitué d'un antihistaminique, un analgésique, un antipyrétique, un anti-inflammatoire non stéroïdien et des mélanges de deux ou plus desdites substances actives.
