Definitions

  • Mitomycin is sold as a cancer chemotherapy agent which has antibiotic activity by Bristol Meyers under the trademark 5 MUTAMYCIN®. See the 38th edition of the Physician Desk Refer ⁇ ence®, page 750 (1984).
  • mitomycin is provided to patients intermit ⁇ tently at six to eight week intervals.
  • the patient may be ambulatory, making use of an adminis ⁇ tration pump of known design, for example, the pump as shown in Cromie U. S. Patent No. 4,416,595.
  • the patient may receive chemotherapy on a 24-hour a day basis, often with the highest • - • 5 concentration of chemotherapy agent being administered to the exact tumor site by means of a catheter.
  • cancer can often be controlled in a manner better than a therapeutic regime using a general ad ⁇ ministration of mitomycin or other antitumor agent.
  • solutions of mitomycin must be provided having better stability than currently available reconstituted mitomycin solutions.
  • the official package circular for Bristol Meyers MUTAMYCIN states that MUTAMYCIN, reconstituted with Sterile Water for Injection to s* . 25 a concentration of 0.5 mg. per ml, is stable for seven days at room temperature. The same product is stated to be stable at * room temperature for three hours when diluted to a concentration of 20 or 40 micrograms per ml with 5% dextrose injection, twelve hours with 0.9% sodium chloride injection, and 24 hours with sodium lactate injection.
  • mitomycin solutions are dis- closed which have long shelf life in solution form, to facilitate packaging and storage of mitomycin solution. This provides a great improvement in the flexibility and convenience of mitomycin therapy.
  • one may store, with ⁇ out freezing, a buffered aqu ⁇ ous solution of mitomycin having a pH of 7.5 to 8.0 for a period of at least 15 days.
  • the solution can retain a mitomycin activity on the 15th day which is at least 90 percent of such activ y on the first day.
  • the solution may contain from 10 micrograms to one mg. of mitomycin per ml. of solution.
  • the buffer mentioned above must be pharmacologically ac ⁇ ceptable so as to be suitable for administration, and should be present in its dosage form in a concentration to provide no more than a minor osmotic gradient with blood.
  • One highly suitable buffer for this purpose is a mixture of mo ⁇ osodium phosphate and disodium phosphate, which is a basically conventional and well-known pharmaceutical buffer.
  • Other suitable buffers may be used as well.
  • mitomycin solutions can be provided which are stable for at least 15 days storage at room temperature, and much longer if refrigerated.
  • stable the intended meaning is that the amount of active mitomycin present in the solution at the end of a given period is at least 90 percent of the amount of active mitomycin present at the beginning of the period over which stability is measured.
  • a solution was prepared by adding to 5 weight percent dextrose injection solution the following amounts of solutes per 100 ml. of solution: 0.134 gram of disodium phosphate; 0.0105 gram of monosodium phosphate; and 5 milligrams of lyophilized mitomycin.
  • the resulting solution has a pH between 7.7 and 7.8. Storage of the solution at room temperature (about 22°C) for 19 days resulted in less than a 10% loss of mitomycin concentration from the solution.
  • a solution suitable for IV administration may be prepared from the above formulation following appropriate sterilization if necessary, for example, by filtration through a 0.22 micron filter.
