Definitions

  • the " present invention relates to novel solutions of somatotropins which remain clear for an extended period of time and which remain clear when subjected to mechanical agitation, and to kits for making the solutions.
  • Somatotropins also known as growth hormones, are polypeptide hormones secreted by the pituitary glands of many animal species. These hormones are valuable for a number of therapeutic uses, and compositions comprising somatotropin can be administered in the treatment of pituitary deficiency in humans and gastrointestinal bleeding or to promote the healing of bone fractures and accelerate the healing of contusions and other wounds. Somatotropins also are useful in promoting meat and milk production in animals when administered through various drug-releasing devices or by injection. (See E.J. Tur an, "Some Effects of Pituitary Anterior Growth Factor" Thesis: Purdue
  • aggregation of adsorbed somatotropin molecules can take place to give soluble or insoluble polymeric forms. This aggregation will manifest itself, for example, as turbidity of the solution or as biological inactivation of the somatotropin protein on stirring or shaking of the aqueous solutions (See A.F. Henson et al., J. Colloid Interface Sci. 32: 162 (1970)).
  • somatotropin solutions which remain clear for extended periods and which do not become cloudy or precipitate when subjected to mechanical agitation.
  • the somatotropin solutions contain a lyophilized somatotropin composition containing about 1 part somatotropin per 2 to 8 parts arginine HCl on a weight basis, the pH of the composition prior to lyophilization within the range of about 7.2 to about 8.5, which is dissolved in a diluent. If the pH of the somatotropin composition prior to lyophilization was less than 7.8, the diluent comprises EDTA, a nonionic surfactant and a buffer.
  • the diluent comprises EDTA and a nonionic surfactant and optionally, further can comprise a suitable buffer or nonbuffering agent if desired. If a non-buffering agent is added, desirably a buffer is not also added to the diluent, although both agents can be used.
  • kits for making the solutions include a vial containing the lyophilized somatotropin composition containing about 1 part somatotropin per 2 to 8 parts arginine HCl on a weight basis.
  • the kits also include a vial containing a biocompatible diluent comprising EDTA and a nonionic surfactant.
  • the diluent also can comprise a buffer or non-buffering agent. If the pH of the somatotropin composition prior to lyophilization was less than 7.8, the vial containing the diluent further comprises a buffer.
  • the vial optionally can contain a buffer or nonbuffering agent.
  • the diluent can be added to the lyophilized somatotropin composition and the resultant mixture then shaken to dissolve the somatotropin.
  • This invention is directed to somatotropin solutions which remain clear for extended periods and which do not become cloudy or precipitate when subjected to mechanical agitation such as shaking or vortex-mixing.
  • a somatotropin solution which remains "clear” is a solution in which the somatotropin does not precipitate after it is dissolved in the diluent.
  • These somatotropin solutions will remain clear after several days of storage, typically at least about 5 days.
  • the somatotropin solutions maintain clarity for at least about 5 days when stored, typically, for example, at about 25°C. At slightly higher storage temperatures, the somatotropin solutions maintain clarity, but possibly for a shorter period of time.

  • the somatotropin solutions contain a lyophilized somatotropin composition, the pH of which prior to lyophilization was at least about 7.2, generally within the range of from about 7.2 to about 8.5.

If the pH of the somatotropin composition prior to lyophilization was 7.8 or higher, the diluent comprises EDTA and an nonionic surfactant and, optionally, a buffer or nonbuffering agent.
  • a non-buffering agent is added to the diluent, desirably a buffer is not also added to the diluent, although both agents can be used. Neither the buffer nor nonbuffering agent need be used if the pH of the . somatotropin composition prior to lyophilization was at least 7.8, but either can be provided to adjust or maintain the isotonicity of the resultant somatotropin solution such that it is less hypertonic. This is desirable if the somatotropin solution will be injected into animals.

Abstract

On prépare des solutions de somatotropine qui restent claires, sur de longues périodes ou lorsqu'on les soumet à une agitation mécanique, en prenant une composition de somatotropine lyophilisée, qui contient environ 1 part de somatotropine pour 2 à 8 parts d'arginine HC1 en poids et dont le pH, avant lyophilisation, était d'environ 7,2 à environ 8,5, composition qu'on mélange avec un diluant biocompatible qui comprend EDTA et un agent tensio-actif non ionique. Si le pH de cette composition de somatotropine était, avant lyophilisation, compris entre 7,2 et 7,8, ce diluant comprend en outre un agent de tamponnement alors qu'autrement, il peut éventuellement comprendre aussi un agent, propice au tamponnement ou non.
