Claims13
A method for treating a facial wrinkle by administering to the patient a pharmaceutical composition comprising a botulinum neurotoxin and a viscous carrier for the botulinum neurotoxin, wherein the patient's facial wrinkles are alleviated for a longer period of time than they are by administration of a pharmaceutical composition which does not comprise a botulinum toxin.
A method for treating a facial wrinkle by local, subdermal administering to the patient a pharmaceutical composition comprising a botulinum neurotoxin type A and a polymeric, hyaluronic acid for the botulinum neurotoxin, wherein the patient's facial wrinkles are alleviated for a period of time which is from about 20% to about 100% longer than the period of time the patient's facial wrinkles are alleviated by administration of a second pharmaceutical composition injected in the same volume into the same patient at the same location, to treat the same facial wrinkles, and which second pharmaceutical composition contains the same amount of the botulinum toxin type A, but which does not comprise the hyaluronic acid.
