ABSTRACT:
A disposable applicator for placing a pharmacologically active agent in contact with a moist body surface, especially the eye is in the form of an elongate strip disposed at one end of which is a soluble matrix element containing the pharmacologically active agent so that on contact with the moist body surface the matrix element separates from the remainder of the strip. In a preferred form the matrix element is attached to the remainder of the strip by a thin water soluble membrane which rapidly dissolves in body fluid thereby releasing the matrix element to the body surface. Processes for the preparation of the disposable applicators are also described.
