TECHNICAL FIELD [0001] The present invention relates to dispensers and, more particularly, to a container and applicator for dispensing a composition such as a pharmaceutical composition. BACKGROUND [0002] Containers used to hold compositions can perform various functions beyond that of simply housing the composition. For example, containers can be sized to dispense a specified dosage of the composition, as well as to assist in the application of the composition to a target area. [0003] For example, in the context of medications used to treat anal ailments such as hemorrhoids, anal fissures, pruritis ani and similar conditions of the anal area (collectively, "heinorrhoids"), current packaging and application methods of compositions have generally been large, re-useable, bulky tubes accompanied by screw-on, multiple use applicators. See, for example, the applicator disclosed in U.S. Pat. No. 4,808,166 to Davidov. Treatments employing this historic methodology have generally resulted in unpleasant and inconvenient incidents for patients and potentially ineffective treatments. The unpleasant incidents include leaky and messy tubes containing the pharmaceutical compound and leaky and dirty applicators resulting from repeated use. Another inconvenience arises from the absolute necessity, for sanitary purposes, of thoroughly cleaning and drying a multiple use applicator after each treatment. Further, since the pharmaceutical is being dispensed from a large, multiple use tube, the potential for a patient to under or over-medicate his or herself exists because dosing amounts cannot be ascertained accurately. [0004] It is therefore desirable to provide a dispenser and method for dispensing a composition that are sanitary, convenient to use, and provide accurate dosage amounts. SUMMARY [0005] The present invention relates to dispensers and, more particularly, to a container and applicator for dispensing a composition such as a pharmaceutical composition. [0006] According to one aspect of the invention, a pharmaceutical dispenser includes a tube including an open end and defining a space filled with a composition, and an applicator including a first end removably coupled to the open end of the tube and a longitudinal portion defining at least one aperture. The dispenser also includes a removable cover extending longitudinally and defining a bore surrounding the longitudinal portion of the applicator. [0007] According to another aspect of the invention, a kit for application of anal medication includes a tube including an open end and defining a space filled with a composition; an applicator including a first end configured to mate with the open end of the tube and a longitudinal portion defining at least one aperture; and a sealed package defining an interior sized to accommodate the tube and the applicator. [0008] According to yet another aspect of the invention, a method for dispensing a pharmaceutical includes: providing a tube including an open end and defining a space filled with a composition; removing a cap from the open end of the tube; mating a first end of an applicator with the open end of the tube; and dispensing the composition through an aperture defined by a longitudinal portion of the applicator onto a target area. [0009] The above summary is not intended to describe each disclosed embodiment or every implementation of the present invention. The figures and the detailed description which follow more particularly exemplify these embodiments.
