Multivitamin Injectable Solution

Example 5

An aqueous solution containing the following ingredients:

• • about 1500 to about 6250 meg cobalamin (vitamin B12);
  • about 150 to about 250 mg ascorbic acid (vitamin C);
  • about 30 to about 50 mg nicotinamide (vitamin B3);
  • about 4.5 to about 7.5 mg thiamine (vitamin B1);
  • about 0.1 to about 0.3 mg pyridoxine HCl (vitamin B6);
  • about 2.7 to about 4.5 mg riboflavin 5-phosphate sodium (vitamin B2);
  • about 7.5 to about 15 mg pantothenic acid (vitamin B5);
  • about 0.08 to about 0.125 mg Zinc sulfate heptahydrate; and
  • about 1 ml q.s., sterile water for injection

The aqueous solution is formulated in physiological saline and adjusted an acceptable pH in the range of about 6.5 to about 7.5 to 7.4, thereby minimizing any injecting pain beyond the needle prick. The aqueous solution may be optionally supplemented with a preservative (e.g., from about 0.01% to about 2% benzyl alcohol), a chemical stabilizer (e.g., from about 0.01% to about 2% gentisic acid), and/or an additional bioactive agent (e.g., from about 0.01% to about 2% hyaluronic acid) depending on anticipated delivery method, shelf-life, and intended effects.
