The invention relates to methods for the treatment of gingivitis, oral plaque and oral or dermatological fungal infections by the administration of a liquid methacrylic acid copolymer composition that contains a release adjusting agent and a pharmacological agent. The composition forms a solid film upon drying, and is capable of accomplishing the sustained release of the pharmacological agent such as to permit its use in the treatment or prevention of dental or dermatological conditions.
