Definitions
- the present invention relates to a drying process of a toxin preparation, and specifically, to a method for preparing a botulinum toxin dried cake by a vacuum drying method.
- Botulinum toxin is a neurotoxin produced by an anaerobic bacterium called Clostridium botulinum ( C.
- Clostridium botulinum C.
- Two types of B (BTX-B) are purified and used medicinally.
- Botulinum toxin inhibits the release of acetylcholine, a neurotransmitter, and blocks muscle contraction signal transmission to relax muscles. That is, by blocking the release of acetylcholine, a neurotransmitter secreted from the presynaptic terminal at the neuromuscular junction, it causes nerve paralysis.
- a filler is a medical device that fills an area with insufficient skin volume with a certain substance, whereas a botulinum toxin preparation is a drug containing a component that reduces muscle use by preventing the release of neurotransmitters that cause muscle contraction. .
- Botulinum toxin is mainly used to suppress or remove glabellar wrinkles and wrinkles around the eyes, and is also used to treat upper limb stiffness, eyelid spasm, foot deformity after stroke, etc., and its indications are gradually expanding.
- botulinum toxin products may be provided in solution form with excipients including sodium chloride and human serum albumin or may be provided as a solid (dry cake) after a drying process.
- Most botulinum toxin manufacturing companies produce products that have gone through the freeze-drying process. Examples include Meditoxin ® , Xeomin ® , Dysport ® , and the like.
- This freeze-drying process is generally known as an advanced drying method for dry formulations of protein drugs, but is not suitable for botulinum toxin formulations using a very small amount of protein.
- the present inventors have made intensive research efforts to develop an optimized vacuum drying method for botulinum toxin that maintains efficacy and stability. As a result, it was found that the botulinum toxin, a protein, can be protected from external stimuli occurring during the process and the drying time can be greatly shortened by efficiently controlling parameters related to the drying process, such as pressure and (shelf) temperature. has been completed.
- an object of the present invention is to provide a method for preparing a botulinum toxin dried cake.
- botulinum toxin a protein
- the drying time can be greatly shortened by efficiently controlling parameters related to the drying process, such as pressure and (shelf) temperature.
- the present invention relates to a method for preparing a botulinum toxin dried cake.
- the present invention provides a method for preparing a botulinum toxin dried cake, comprising drying the botulinum toxin under reduced pressure at a pressure of 1,500 to 60,000 mTorr and a temperature of 3 ° C to 25 ° C.
- botulinum toxin refers to a toxin that can be obtained by purification from a Clostridium botulinum ( C. botulinum ) strain.
- Clostridium botulinum C. botulinum
- a botulinum toxin produced by a strain it has a size of about 150 kDa.
- a botulinum toxin complex which is a complex material in which a botulinum toxin and one or more non-toxin proteins are bound, it has a size of about 300 kDa to 900 kDa.
- the botulinum toxin may be used for various medical purposes, as well as suppression or improvement of glabellar wrinkles and crow's feet.
- cake refers to a material dried on the bottom surface of a vial dry formulation, and may be used separately from a powder formulation.
- the botulinum toxin producing strain of the present invention is Clostridium botulinum ( C. botulinum ). More specifically, Clostridium botulinum Type A (ATCC 19397) strain may be used, but is not limited thereto.
- Botulinum toxin type A has been approved by the US Food and Drug Administration (FDA) for the treatment of essential blepharospasm, strabismus and hemifacial spasm in patients 12 years of age and older, and for the treatment of cervical dystonia, glabellar (facial) wrinkles and treatment of hyperhidrosis. Approved.
- FDA US Food and Drug Administration
- the botulinum toxin of the present invention may be prepared using various conventionally known processes, and is not particularly limited.
- the botulinum toxin-producing strain culture solution may be obtained by culturing a botulinum toxin-producing strain and undergoing precipitation, filtering, re-dissolution, and purification once or twice or more.
- the botulinum toxin of the present invention is suitable for culturing Clostridium botulinum ( C. botulinum ) cultured in a specific medium well understood by those skilled in the art. From the culture, it is prepared by purifying the botulinum toxin complex through a series of acid precipitations into a crystalline complex composed of an active high molecular weight toxin protein and related hemagglutinin proteins, and dissolving the purified crystalline complex in a solution containing saline and a stabilizing agent. It may be a culture medium of a botulinum toxin-producing strain.
- the culture conditions of the botulinum toxin-producing strain culture medium can be appropriately adjusted according to the culture environment based on the common knowledge of those skilled in the art.
- the concentration of the botulinum toxin of the present invention may be 250 U/mL to 5,000 U/mL.

- Drying can be largely done in two steps. Separation of water molecules connected by hydrogen bonding, and removal of water molecules having various interactions with other excipients and proteins constituting the final stock solution. When water molecules form bonds, they can be separated with less energy than water molecules that interact with other molecules. In most cases, water molecules are bonded together, and evaporation is performed primarily by separating them. In this process, the liquid phase product changes to the gas phase. Secondary evaporation occurs when the bond between water molecules and other excipients is broken during the interaction, and when this process is almost completed, it is determined that drying is completed. As a result of moisture content measurement, it must have a moisture content of 3% or less to satisfy the standard for dry cake injections.
