Films


As oral film dosage forms gain popularity, the Dow family of film-forming excipient polymers can speed your development and increase your chances for success.
METHOCEL* hypromellose, ETHOCEL* ethylcellulose, and POLYOX™ Water-Soluble Resins NF each offer a long history of success in pharmaceuticals. These polymers have been used for their outstanding controlled release and film-forming functionalities. And each has already shown the potential to be an effective major component of oral film dosage forms.
They can be formulated into either clear or opaque films of varying thickness for different dissolution rates and applications. METHOCEL and POLYOX excipients are water-soluble, while water-insoluble ETHOCEL excipients give you additional capabilities to manage water-sensitive ingredients, or those that require greater taste masking functionality.
