The present invention relates to a pharmaceutical botulinum toxin composition containing tannic acid as an active ingredient. A pharmaceutical botulinum toxin composition containing tannic acid, provided in one aspect of the present invention, improves the activity of botulinum neurotoxin itself, and causes the botulinum neurotoxin to stay at the injected site by means of the properties of tannic acid and is prevented from diffusing into the blood, and thus can minimize conventional botulinum toxin side effects caused by the diffusion of botulinum neurotoxin. |
