摘要:
The present invention provides improved formulations of botulinum toxin that increase delivery of the botulinum toxin to neural and associated tissues and exhibit a higher specific neurotoxicity and higher potency (in LD50 Units) than available formulations of botulinum toxins. These improved formulations enable physicians to treat a wide variety of pathological conditions with a lower toxin load that reduces the risk of inducing an immune response against the toxin and its associated proteins that may ultimately lead to the development of toxin resistance. These benefits are particularly important in the treatment of conditions that require high-dose or chronic administration of botulinum toxin. Additionally, the decreased in LD50 Unit doses of inventive formulations allows for controlled administration limits diffusion. The present invention also provides methods of treating neuromuscular diseases and pain, using low-dose botulinum toxin.
摘要:
An extended duration pharmaceutical composition including a botulinum neurotoxin, an adhesive agent, and a stabilizing macromolecule. The composition effectively has all the properties to cause chemodenervation through a facial muscle, or other muscle, that predecessor botulinum toxin preparations have had as well as agents which create a fibrotic adhesion on the under surface of facial muscles (or other muscles) to the facial bone (or other bones) so that the facial bone tethers the under surface of the facial muscle, thereby causing fibrosis to the underlying fat pad. The composition can be used to treat various disorders. Methods of modifying facial contour for functional or cosmetic purposes in a human patient are disclosed which involve injecting a therapeutically effective amount of the disclosed compositions. A method of quantifying the extended duration of the compositions is also disclosed.
摘要:
The present invention provides compositions that contain botulinum toxin and a hyaluronidase, and that lack human or recombinant serum albumin. The present invention also provides methods of administering the pharmaceutical composition to a subject in need thereof.
摘要:
Pharmaceutical application of a chemodenervating agent, particularly botulinum toxin, reduces inflammatory response and serves as an anti-inflammatory agent without systemic side effects and with long duration action, on the order of 12-24 weeks. In one embodiment, the effective dosage for allergy provoked inflammation reduction is an order of magnitude less than dosages associated with treatment of regional movement diseases, since the agent works to reduce inflammation by reducing histamine and other preformed mediator releases associated with mast cell degranulation.

Formulations and methods of treatment are disclosed for prevention and/or treatment of visual loss from age-related macular degeneration. The disclosed formulations include botulinum neurotoxin (e.g., botulinum neurotoxin or a fragment thereof, either in pure form or with one or more peptide fragments and/or neurotoxin associated proteins). In some embodiments, the disclosed formulations also include one or more anti-VEGF agents. The disclosed formulations may be applied to an intraocular or extraocular region of a patient. If applied to an extra ocular region of a patient, the botulinum-based pharmaceutical formulation may be transported to the intra-ocular region of the patient via axoplasmic transport, thereby allowing the active ingredient(s) to penetrate into the choroid, neuro-retina, and/or retinal pigment epithelium without direct injection into the eye, allowing for improved therapeutic safety by eliminating risk of retinal detachment, retinal break, retinal hemorrhage, and blindness associated with direct injection into the eye.

The methods described herein allow for increased blood flow to the choroid, which improves removal of metabolites and intra retinal fluid and also serves to arrest, reverse and/or delay early and later stages of age-related macular degeneration.
摘要:
A highly sensitive method of analyzing a sample for the presence or activity of botulinum neurotoxin (BoNT) or antibodies specific for botulinum neurotoxin is disclosed. In one embodiment, the method comprises the steps of preparing primary non-human mammalian or avian spinal cord cells, and exposing the cells to a test sample, in parallel with a control sample, and examining the extent of cleavage of the intracellular neuronal target protein in both the test and control sample.

Additionally, relative timing of botulinum application and specific staging of wet, exudative macular degeneration relative to the paraorbital applications are disclosed. Further, a mammalian model is proposed to determine the fraction of botulinum most effective at altering VEGF production and associated with suppression of chorio-retinal leakage from macular pathologies.
