## Abstract

A multidose package containing an imiquimod formulation suitable for treating topical conditions includes: a) a dispensing aperture for dispensing the formulation from the package; b) a reservoir containing sufficient formulation to provide two or more doses; c) a metered dosage element for measuring a predetermined dose of the formulation, the element including an inlet from the reservoir and an outlet to the dispensing aperture; and d) an actuating element operating the dosage element so the predetermined dose is delivered to the dispensing aperture; wherein the dose is dispensed without microbial or other contamination or degradation of the formulation in reservoir. A corresponding course of treatment for various maladies includes providing a multidose package containing an imiquimod formulation suitable for the treatment. A corresponding method of treatment of diseases with multiple doses of an imiquimod formulation includes multiple doses provided by a multidose package.

## Claims

### Claim 1

A method of treatment of actinic keratosis, superficial basal cell carcinoma or external genital warts in a patient in need thereof, said method comprising administering to said patient multiple doses of an imiquimod formulation, wherein said multiple doses are provided by a multidose package, said package comprising:
a) a dispensing aperture for dispensing the formulation from the package;
b) a reservoir containing a sufficient amount of said formulation to provide two or more doses;
c) a metered dosage means for measuring a predetermined dose of said formulation, said means comprising an inlet from said reservoir and an outlet to said dispensing aperture, wherein the metered dosage means is in the form of a positive displacement pump and is operated by an actuator associated with the outlet; and
d) an actuating means operating said dosage means such that the predetermined dose is delivered to said dispensing aperture; wherein said dose is dispensed without microbial or other contamination or degradation of the formulation in reservoir.

### Claim 2 (depends on 1)

The method of treatment of claim 1, wherein the inlet comprises a one way valve to the reservoir.

### Claim 3 (depends on 2)

The method of treatment of claim 2, wherein the one way valve isolates the reservoir contents and prevents any back-flow of air and/or formulation into the reservoir once a volume of formulation enters the metered dosage means.

### Claim 4 (depends on 1)

The method of treatment of claim 1, wherein an airless pump is associated with said metered dosage means.

### Claim 5 (depends on 4)

The method of treatment of claim 4, wherein the airless pump has a body made of HD polyethylene, a piston made of LD polyethylene, an outlet port or stem of polypropylene and an inlet port or dip tube of polypropylene.

### Claim 6 (depends on 1)

The method of treatment of claim 1, wherein the imiquimod is present in the formulation in an amount of 0.1 to 10% w/w.

### Claim 7 (depends on 1)

The method of treatment of claim 1, wherein the imiquimod is present in the formulation in an amount of 5% w/w.

### Claim 8 (depends on 1)

The method of treatment of claim 1, wherein the method of treatment is for actinic keratosis.

### Claim 9 (depends on 8)

The method of treatment of claim 6, wherein the package has a volume of formulation in the reservoir suitable for 6, 12 or 24 doses.

### Claim 15 (depends on 6)

The method of treatment of claim 6, wherein the predetermined dose is about 80 mg of formulation.

### Claim 16

A method for treating external genital warts in a patient in need thereof, said method comprising administering to said patient multiple doses of an imiquimod formulation, wherein said multiple doses are provided by a multidose package, said package comprising: a dispensing aperture for dispensing the formulation from the package; a reservoir containing a sufficient amount of said formulation to provide the required number of dosages for the course of treatment; a metered dosage means for measuring a predetermined dose of said formulation, said means comprising an inlet from said reservoir and an outlet to said dispensing aperture, wherein the metered dosage means is in the form of a positive displacement pump and is operated by an actuator associated with the outlet; and an actuating means for operating said dosage means such that the predetermined dose is delivered to said dispensing aperture; wherein said dose is dispensed without microbial or other contamination or degradation of the formulation in reservoir and wherein the imiquimod is present in the formulation in an amount of 0.1 to 10% w/w.

### Claim 17

A method of providing a multidose package containing an imiquimod formulation suitable for treating a topical condition selected from the group consisting of actinic keratosis, superficial basal cell carcinoma and external genital warts, said package comprising: a) a dispensing aperture for dispensing the formulation from the package; b) a reservoir for said formulation; c) a metered dosage means for measuring a predetermined dose of said formulation, said means comprising an inlet from said reservoir and an outlet to said dispensing aperture, wherein the metered dosage means is in the form of a positive displacement pump and is operated by an actuator associated with the outlet; and d) an actuating means for operating said dosage means such that the predetermined dose is delivered to said dispensing aperture; wherein said dose is dispensed without microbial or other contamination or degradation of the formulation in reservoir; said method comprising filling said reservoir with a sufficient amount of said formulation to provide treatment for 2 weeks, 4 weeks, 8 weeks or 16 weeks.
