METHOD AND APPARATUS FOR DISPENSING A COMPOSITION
First Claim
1. A disposable single-use pharmaceutical dispenser for anorectal topical application, comprising:
- a reservoir portion defining a space, the reservoir portion being formed of a material deformable by squeezing, the reservoir portion has a length of less than approximately 5.5 to 6.5 cm;
the single dosage amount of a pharmaceutical composition comprising lidocaine and hydrocortisone acetate, the pharmaceutical composition substantially filling the space of the reservoir portion, the single dosage amount of the pharmaceutical composition formulated for topical non-systemic treatment of an anal ailment selected from the group consisting of hemorrhoids, anal fissures, and pruritis ani; and
an applicator portion defining one or more apertures, the applicator portion having a length of approximately 4.5 to 5.0 cm, the applicator portion comprising a first end adjacent to the reservoir portion and a longitudinal portion extending away from the reservoir portion, wherein the first end is flanged outward from the longitudinal axis of the applicator portion such that the first end defines an outer diameter that is substantially greater than any outer diameter along the longitudinal portion and that is less than the outer diameter of the portion of the reservoir portion adjacent the first end,wherein the dispenser is configured, by squeezing the reservoir portion, for topically administering the single dosage amount of the pharmaceutical composition onto the surface of an anal target area afflicted by the anal ailment, wherein the squeezing causes a substantial portion of the single dosage amount of the pharmaceutical composition to be dispensed through the one or more apertures onto the anal target area, andwherein an open end of the reservoir portion is threaded for removable coupling to the applicator portion.

17. A method for topically dispensing a single dosage amount of a pharmaceutical composition, comprising:
-
removing a covering from an applicator portion of a disposable dispenser, the dispenser also forming a reservoir portion, the reservoir portion being formed from a material deformable by squeezing, the reservoir portion defining a space containing a single dosage amount of a pharmaceutical composition formulated for the topical treatment of an anal ailment selected from the group consisting of hemorrhoids, anal fissures, and pruritis ani, the pharmaceutical composition comprising lidocaine and hydrocortisone acetate; inserting the applicator portion into an anal area of an anus, the applicator portion defining one or more apertures and having a length of less than approximately 5.0 cm; topically administering the single dosage amount of the pharmaceutical composition onto the surface of an anal target area afflicted by the anal ailment by dispensing a substantial portion of the single dosage amount through one or more apertures defined by an applicator portion of the dispenser, wherein the dispensing step is carried out by squeezing the reservoir portion to cause at least the substantial portion of the single dosage amount to dispense from the one or more apertures; and discarding the dispenser after use.

18. A kit for topical application of anal medication, the kit comprising:
-
a disposable dispenser comprising; a reservoir portion less than approximately 6.5 cm in length, the reservoir portion defining a space, the reservoir portion formed from a material deformable by squeezing; a single dosage amount of a pharmaceutical composition formulated for the topical treatment of an anal ailment selected from the group consisting of hemorrhoids, anal fissures, and pruritis ani, the single dosage amount substantially filling the space and comprising lidocaine and hydrocortisone acetate; and an applicator portion less than approximately 5.0 cm in length comprising a first end adjacent the reservoir portion and a longitudinal portion defining at least one aperture, the first end being flanged outward from the longitudinal axis of the applicator portion such that the first end defines an outer diameter that is substantially greater than any outer diameter of the longitudinal portion and that is less than the outer diameter of the portion of the reservoir portion adjacent the first end, the longitudinal portion being tapered from the first end to an opposite end of the longitudinal portion; a removable cover configured to surround the longitudinal portion of the applicator portion; and a blister pack defining an interior configured to accommodate the reservoir portion, the applicator portion, and the removable cover, the blister pack having a child resistant seal, wherein the dispenser is configured, by squeezing the reservoir portion, for topically administering the single dosage amount of the pharmaceutical composition onto the surface of an anal target area afflicted by the anal ailment, wherein the squeezing applies pressure in a direction not substantially parallel to the longitudinal axis of the reservoir portion and causes a substantial portion of the single dosage amount of the pharmaceutical composition to dispense from the at least one aperture onto the anal target area.
