Topically applied clostridium botulinum toxin compositions and treatment methods

Abstract

Hyperactive glandular conditions are treated using topically formulated botulinum toxin compositions. In the preferred embodiment of the invention, topical botulinum preparations are applied directly to the skin by a patient as needed to suppress his or her hyperhidrosis, bromhidrosis, chromhidrosis, nevus sudoriferous, acne, seborrhiec dermatitis or other glandular condition. In other embodiments, topical botulinum toxins are applied with the aid of mechanical, electrical, and / or chemical transdermal delivery enhancers.

Description

[0001] This application is based on U.S. Provisional Patent Application Serial No. 60 / 343,389, filed on Dec. 18, 2001, and entitled "Method and Compositions for Treatment of Hyperhidrosis Using Clostridium Botulinum Toxin." The contents of the Provisional Patent Application are incorporated herein by reference.[0002] 1. Field of the Invention[0003] This invention relates generally to the field of medicine. In particular, it relates to methods and compositions that are especially suitable for the treatment of hyperhidrosis, and other conditions of the glands, skin, or smooth and skeletal muscle, and involve the topical application of one or more microbial neurotoxins.[0004] 2. Description of the Related Art[0005] Traditionally, bacterial toxins, such as those produced by the genus Clostridia, were best known for their wide-ranging pathogenic effects, including food poisoning, tetanus, and botulism. Virulent botulinum strains are divided into seven groups, with each group producing an...

Benefits of technology

[0017] Another goal of the invention is to provide a method and compositions for the treatment of hyperhidrosis that are painless and easy to apply directly by a patient.

Problems solved by technology

While the potency of these toxins differ somewhat (and their physiological modes of action vary), they all result in chemodenervation.

Death often results from a gradual paralysis of the muscles required for respiration.

This disorder, which appears to be genetically based, is a cause of great distress for sufferers.

It can also be expensive.

Aside from the disruption of normal social activities, excessive sweating frequently discolors and thereby ruins clothing.

All of these therapies have significant drawbacks and are often unsuccessful.

First, introducing BOTOX through intradermal injections is painful and often involves numerous percutaneous sticks in order to provide relief for the affected area. Moreover, because relief is only temporary, having a medical practioner administer each follow-up injection can be time-consuming, costly, and inconvenient.
