CA 2679067

Pharmaceutical packages and methods for enhancing the safety of imiquimod when used to treat children affected by skin disorders are disclosed. More particularly, the safety profile of imiquimod use is enhanced by providing information to the children, guardians of the children, including parents and health care professionals, that systemic absorption of imiquimod and other effects may be observed when imiquimod therapy is used to treat children of between about 2 and about 12 years of age. Examples of systemic absorption include a serum imiquimod concentrations of less than about 2 ng/mL, a decrease in median white blood cell count by about 1.4*109/L or a decrease in median absolute neutrophil count by about 1.42*109/L Topical and/or transdermal delivery of imiquimod, including creams, ointments, gels, lotions, salves and pressure- sensitive adhesive compositions to treat dermatological disorders in children, namely, molluscum contagiosum, viral infections, such as Type 1 or Type Il Herpes simplex infections and condyloma acuminata, genital warts and perianal warts, actinic keratosis and superficial basal cell carcinoma, and to induce interferon biosynthesis, are disclosed.

L'invention concerne des procédés et des trousses pharmaceutiques servant à augmenter la sécurité d'imiquimod quand on l'utilise pour traiter des enfants atteints de troubles épidermiques. On augmente, plus spécifiquement, le profil de sécurité d'imiquimod au moyen d'informations prodiguées aux enfants et aux personnes responsables des enfants, y compris les parents et les professionnels de santé, indiquant entre autres les effets observés à la suite de l'absorption systémique d'imiquimod lors d'un traitement d'enfants entre 2 et 12 ans. Des exemples de l'absorption systémique consistent en des concentrations sériques d'imiquimod inférieures à 2ng/mL, une diminution du nombre moyen des globules blancs d'environ 1.4*109/L ou une diminution du nombre moyen absolu des neutrophiles d'environ 1.42*109/L. L'invention concerne l'administration topique et/ou transdermique d'imiquimod, y compris crèmes, onguents, gels, lotions, pommades et compositions adhésives sensibles à la pression pour traiter des troubles dermatologiques chez l'enfant, notamment, molluscum contagiosum, des infections virales, telles que des infections par Herpès simplex de type I ou II ou le condylome acuminé, les verrues génitales ou périanales, la kératose actinique et le carcinome basocellulaire, ainsi que pour provoquer la biosynthèse des interférons.
