Pharmaceutical delivery compositions and uses thereof
In some aspects, the disclosure relates to compositions and methods for skin repair and regeneration. In some embodiments, compositions described by the disclosure comprise natural products (e.g., extracts) combined with biotechnological excipient systems, such as bio surfactants, suitable for the repair of compromised skin, such as mucosal tissue (e.g., oral mucosal tissue).
1. A composition comprising:
(i) a drug delivery system comprising a carbonate buffer solution, at least two different biosurfactants, at least one hygroscopic agent, and at least one antioxidant; and
(ii) at least one bioactive agent present at about 0.1% (w/w) to about 4% (w/w), wherein the composition has a pH that ranges from about 8.5 to about 9.5 wherein the at least one bioactive agent is selected from the group consisting of: Melissa officinalis extract; propolis;
baicalin; marine algae powder selected from Enteromorpha linza extract, Ulva lactuca extract, Porphyra haitanensis, or Laminaria japonica extract; aloe vera; carrot oil; and one or more antiviral agent;
wherein the at least two biosurfactants are rhamnolipid and sophorolipid; and wherein the rhamnolipid and sophorolipid are each present at about 0.01% (w/w) to about 6.5% (w/w);
wherein the at least one hygroscopic agent is polyethylene glycol;
wherein polyethylene glycol is present at about 0.1% (w/w) to about 20% (w/w);
wherein the at least one antioxidant is alpha-tocopherol or butylated hydroxytoluene; and
wherein the alpha-tocopherol or butylated hydroxytoluene is present at about 0.01% (w/w) to about 2.92% (w/w).
