Long lasting effect of new botulinum toxin formulations
The invention relates to the use of an animal-protein-free botulinum toxin composition to treat a disease, disorder or condition in a patient in need thereof whereby the animal-protein-free botulinum toxin composition exhibits a longer lasting effect in the patient compared to an animal-protein-containing botulinum toxin composition.
1. A method for treating a condition in a patient in need thereof, the method comprising the step of locally administering a therapeutically effective amount of an animal-protein-free botulinum toxin composition, whereby a symptom of the condition is thereby effectively alleviated for a period of time longer than that of an animal-protein-containing botulinum toxin composition, and wherein the condition is selected from the group consisting of glabellar lines, marionette lines, brow furrows, lateral canthal lines, and any combination thereof.
2. The method of claim 1 , wherein the animal-protein-free botulinum toxin composition is in a form selected from the group consisting of a liquid composition and a lyophilized composition.
3. The method of claim 2 , wherein the liquid composition comprises botulinum toxin, polysorbate 20, and methionine.
4. The method of claim 2 , wherein the lyophilized composition comprises botulinum toxin, polysorbate, and methionine, and one or more components selected from the group consisting of a sugar, a sugar alcohol, and an ionic compound.
5. The method of claim 1 , wherein the botulinum toxin is selected from a group consisting of botulinum toxin serotypes A, B, C, D, E, F, and G.
6. The method of claim 1 , wherein the animal-protein-free botulinum toxin composition persists in the patient for a period longer than that of an animal-protein-containing botulinum toxin composition.
7. The method of claim 1 , wherein the effective alleviation of a symptom of the condition is the temporary improvement in appearance of moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity.
8. The method of claim 7 , wherein the animal-protein-free composition provides effective alleviation for a period of time of at least 16 weeks.
9. A method for treating a condition in a patient in need thereof, the method comprising the step of locally administering a therapeutically effective amount of an animal-protein-free botulinum toxin composition, wherein the composition is administered at an interval of time between a first treatment and a second treatment effective to maintain alleviation of at least one symptom of the condition, that is greater than the interval of time for an animal-protein-containing botulinum toxin composition dosed at the same amount and administered in the same manner and to the same location(s) as that of the animal-protein-free composition, and wherein the condition is selected from the group consisting of glabellar lines, marionette lines, brow furrows, lateral canthal lines, and any combination thereof.
10. The method of claim 9 , wherein the animal-protein-free botulinum toxin composition is in a form selected from the group consisting of a liquid pharmaceutical composition and a pharmaceutical lyophilized preparation.
11. The method of claim 10 , wherein the liquid pharmaceutical composition comprises botulinum toxin, polysorbate 20, and methionine.
12. The method of claim 10 , wherein the pharmaceutical lyophilized preparation comprises botulinum toxin, polysorbate, and methionine, and one or more components selected from the group consisting of a sugar, a sugar alcohol, and an ionic compound.
13. The method of claim 9 , wvherein the botulinum toxin is selected from a group consisting of botulinum toxin serotypes A, B, C, D, E, F, and G.
14. The method of claim 9 , wherein the interval of time between a first treatment and a second treatment is greater than 3 months.
