Prebiotic suppositories
A composition for vaginal insertion is in the form of a softgel, a two-part gelatin capsule, a tablet, or a suppository. The composition is designed to promote the growth of native vaginal flora, but does not promote the growth of Gardenerella vaginalis and Candida albicans . The composition includes a prebiotic in a pharmaceutically acceptable excipient and is essentially free of probiotics, lactoferrin, and plant extracts containing isoflavones.
1. A vaginal suppository for vaginal health maintenance consisting essentially of:
about 2-10% by weight of a dry prebiotic suspended in a suppository base by about 0.5-1.5% weight of a dry inorganic suspending agent in the form of a solid at room temperature that melts at about 94° F. to about 100° F.; and
about 0.01-0.04% by weight of a weak acid;
wherein the balance of the vaginal suppository is the suppository base;
wherein the vaginal health maintenance entails promotion of the growth of strains of native vaginal flora Lactobacillus gasseri and Lactobacillus crispatus that ferment the prebiotic, but does not promote the growth of Gardenerella vaginalis and Candida albicans;
wherein the composition is essentially free of probiotics, lactoferrin, and plant extracts containing isoflavones, and is free of water and therapeutic agents;
wherein the prebiotic is a bifidogenic oligosaccharide selected from the group consisting of fructo-oligosaccharide, galacto-oligosaccharide, inulin, isomalto-oligosaccharide, lactulose, soy-oligosaccharide, xylo-oligosaccharide, and combinations thereof.
2. The vaginal suppository of claim 1 further consists essentially of a preservative as about 0.1-0.18% by weight of the suppository.
3. The vaginal suppository of claim 1 wherein the inorganic suspending agent comprises silicon dioxide.
4. The vaginal suppository of claim 1 wherein the suppository base comprises a polyethylene glycol.
5. The vaginal suppository of claim 1 wherein the prebiotic includes fructo-oligosaccharide.
6. The vaginal suppository of claim 1 wherein the suppository base includes polyethylene glycol, the prebiotic is fructo-oligosaccharide, and further consists essentially of a preservative.
7. The vaginal suppository of claim 6 wherein the polyethylene glycol is about 97% by weight of the composition and the fructo-oligosaccharide is about 2% by weight of the composition.
8. The vaginal suppository of claim 6 wherein the polyethylene glycol comprises a mixture of polyethylene glycol 1000 and polyethylene glycol 1450.
9. The vaginal suppository of claim 6 wherein the preservative includes methylparaben and is about 0.1% by weight of the composition; the inorganic suspending agent includes silicon dioxide and is about 0.8% by weight of the composition; and the pH adjuster includes lactic acid and is about 0.03% by weight of the composition.
10. A method for promoting vaginal health maintenance by the growth of native vaginal flora, the method comprising:
inserting a vaginal suppository into a vagina, the vaginal suppository consisting essentially of:
about 2-10% by weight of a dry prebiotic suspended in a suppository base by about 0.5-1.5% weight of a dry inorganic suspending agent in the form of a solid at room temperature that melts at about 94° F. to about 100° F.; and
about 0.01-0.04% by weight of a weak acid;
wherein the balance of the vaginal suppository is the suppository base, the vaginal suppository is essentially free of probiotics, lactoferrin, and plant extracts containing isoflavones, and is free of water and therapeutic agents;
wherein the prebiotic is a bifidogenic oligosaccharide selected from the group consisting of fructo-oligosaccharide, galacto-oligosaccharide, inulin, isomalto-oligosaccharide, lactulose, soy-oligosaccharide, xylo-oligosaccharide, and combinations thereof; and
allowing at least some strains of native vaginal flora Lactobacillus gasseri and vaginal Lactobacillus crispatus to ferment the prebiotic thereby promoting the growth of said strains, but not the growth of Gardenerella vaginalis and Candida albicans , such that vaginal health maintenance is promoted.
11. The method of claim 10 wherein the vaginal suppository helps prevent bacterial vaginosis.
12. The method of claim 10 wherein the allowing step includes allowing about five to eight hours to elapse.
13. The method of claim 10 wherein the inserting step and the allowing steps are repeated once daily.
14. The method of claim 10 wherein the inorganic suspending agent comprises silicon dioxide.
15. The method of claim 10 wherein the suppository base comprises a polyethylene glycol.
16. The method of claim 10 wherein the prebiotic includes fructo-oligosaccharide.
17. The method of claim 10 wherein the suppository base includes polyethylene glycol and the prebiotic is fructo-oligosaccharide.
18. The method of claim 17 wherein the polyethylene glycol is about 97% by weight of the composition and the fructo-oligosaccharide is about 2% by weight of the composition.
19. The method of claim 17 wherein the polyethylene glycol comprises a mixture of polyethylene glycol 1000 and polyethylene glycol 1450.
20. The method of claim 10 wherein the inorganic suspending agent includes silicon dioxide and is about 0.8% by weight of the composition; and the pH adjuster includes lactic acid and is about 0.03% by weight of the composition, and the vaginal suppository further consists essentially of a preservative at about 0.1% by weight of the composition.
