CA 2250188

A method of stimulating ciliary beat frequency in a subject in need of such treatment is disclosed. The method comprises administering to the airways, ears, eyes, or genito-urinary tract of the subject a triphosphate nucleotide such as uridine 5'-triphosphate (UTP), an analog of UTP, or any other analog, in an amount effective to stimulate ciliary beat frequency. This method is useful for treating patients afflicted with ciliary dyskinesia, Kartagener's syndrome, or any other disease involving dysfunction of ciliary movement, such as male infertility caused by impairment of propulsion of the spermatozoa or immune deficiency caused by impairment of ciliary movement in neutrophils or macrophages. Pharmaceutical formulations and methods of making the same are also disclosed. Methods of administering the same would include any liquid suspension (including nasal spray or nasal or eye drops), oral, inhaled by nebulization, topical, injected, suppository, intra-operative by instillation or application, or ex vivo direct application to spermatozoa.

Méthode de stimulation de la fréquence des battements ciliaires chez un sujet nécessitant un tel traitement, consistant à administrer aux voies respiratoires, aux oreilles, aux yeux ou au tractus génito-urinaire du sujet un nucléotide triphosphaté tel que l'uridine 5'-triphosphate (UTP), un analogue de l'UTP ou tout autre analogue, en une dose suffisante pour stimuler ladite fréquence de battements. Cette méthode permet de traiter des patients souffrant de dyskinésie ciliaire, du syndrome de Kartagener ou de toute autre maladie impliquant un dysfonctionnement des mouvements ciliaires, telle que la stérilité masculine causée par une altération de la propulsion des spermatozoïdes ou une déficience immunitaire causée par une altération des mouvements ciliaires dans les neutrophiles ou les macrophages. Des formulations pharmaceutiques et des procédés de préparation de ces dernières sont également décrits. Les méthodes d'administration de ces préparations peuvent comprendre l'administration sous forme de toute suspension liquide (y compris la pulvérisation nasale ou les gouttes nasales ou oculaires), l'administration orale, l'inhalation par nébulisation, ou encore l'administration topique, par injection, par suppositoire, peropératoire par instillation ou application, ou par application directe, ex vivo, aux spermatozoïdes.
