Abstract: An apparatus for the simultaneous dispensing of fluids from multiple containers in a pre-determined ratio. The apparatus has a pump, at least two fluid containers, a fluid transfer device including dip tubes to transfer fluid from the containers to the pump, a venting system that prevents the creation of pressure differentials between the containers, and a device to open and close the dip tubes so leakage from the containers can be prevented.

Abstract: Novel compositions comprising wetted mixtures of poorly soluble drugs with water soluble polymers useful in increasing bioavailability are disclosed.

Abstract: A novel method of treating aphthous stomatitis, lesions, sores and blisters affecting the mucous membranes and surrounding areas comprising topical application of tape dosage forms containing minor amounts of topically effective active ingredients is disclosed.

Abstract: The disclosure is directed to dosage forms for buccal administration of a drug and are directly applicable to the interior surfaces of the mouth. The dosage form is comprised of a support member, which is water insoluble, waterproof and flexible, a moisture activated, adhesive precursor applied to one surface of the support member and an active ingredient applied to the central portion of the support member either directly or dispersed in a matrix. In one embodiment, a recess is provided in the support member to receive the active ingredient. When the dosage form is applied directly to the interior surface of the mouth, contact with saliva activates the adhesive and causes the support member to adhere to the interior surface of the mouth, thereby exposing the active ingredient to a limited area of the oral mucosa while isolating the active ingredient from the remainder of the oral environment.
