Mucositis is treated and/or prevented by administrating to a patient a formulation containing a tetracycline and at least one cationic polymer and/or mucoadhesive material. The tetracycline may be in the form of a pharmaceutically acceptable salt or a base. The formulations may optionally also contain an antifungal agent to prevent fungal overgrowth due to reduction in the normal oral flora by the tetracycline. The formulation can be formed into liquid or solid dosage forms such as mouth rinse or tablet. Such compositions have the advantage of prolonged retention of the tetracycline in the mucosa of the oral cavity.

L'invention concerne une méthode de traitement et/ou de prévention de mucosité. Cette méthode consiste à administrer à un patient une formulation contenant une tétracycline et au moins un polymère cationique et/ou une matière muco-adhésive. La tétracycline peut se présenter sous la forme d'un sel pharmaceutiquement acceptable ou d'une base. Les formulations peuvent éventuellement également contenir un agent antifongique pour prévenir une prolifération fongique due à la réduction de la flore buccale normale, par la tétracycline. Cette formulation peut être formée en formes dosifiées liquides ou solides, notamment un bain de bouche ou un comprimé. De telles compositions présentent l'avantage d'une rétention prolongée de la tétracycline dans la muqueuse de la cavité buccale.
