Methods for Increasing the Bioavailability of OTC and Pharmaceutical Drugs
The present invention relates to compositions and methods for enhancing the efficacy of drug compounds. The subject invention utilizes an adjuvant composition comprising of one or more microbial-produced biosurfactants and/or isoforms thereof to enhance bioavailability, stability, and localization of the drugs in a subject, to reduce the total dosage that is required, and to prolong the pre-administration stability of the drugs.
1 . A composition comprising an active component and an adjuvant component, the active component comprising a drug compound, a vitamin, a mineral, a supplement, an enzyme and/or an herbal extract;
wherein said adjuvant component comprises an efficacy-enhancing amount of a biosurfactant; and
wherein stability of the active component is enhanced compared to a composition comprising the same active component without the adjuvant component.
2 . (canceled)
3 . The composition of claim 1 , wherein the biosurfactant is selected from lipopeptides and glycolipids.
4 . The composition of claim 3 , wherein the glycolipids are selected from sophorolipids, rhamnolipids, trehalose lipids, cellobiose lipids and mannosylerythritol lipids.
5 . (canceled)
6 . The composition of claim 1 , wherein a biosurfactant is present in critical micelle concentration (CMC).
7 . The composition of claim 1 , formulated for administration to a subject through a route selected from oral, injection, rectal, vaginal, ocular, aural, nasal, mucosal, inhalation, nebulization, and dermal.
8 . The composition of claim 1 , formulated as a biosurfactant-based delivery system, wherein the drug is encapsulated in a biosurfactant-based particle.
9 . The composition of claim 1 , wherein the active component comprises a pharmaceutical or OTC drug compound selected from daptomycin, clindamycin, azithromycin, moxifloxacin, bortezomib, lenalidomide, abiraterone acetate, pegfilgrastim, capecitabine, doxorubicin, erlotinib, aspirin, naproxen, ibuprofen, metformin, donepezil, nitazoxanide, varenicline, testosterone, sildenafil, vardenafil, tadalafil, and indinavir.
10 . The composition of claim 1 , wherein the active component comprises a vitamin selected from vitamin A, D, E and K.
11 . The composition of claim 1 , wherein the active component comprises cannabidiol.
12 . The composition of claim 1 , wherein the active component comprises an enzyme selected from CoQ10 and nattokinase.
13 . A method for enhancing the stability, of an active component selected from a drug compound, a vitamin, a mineral, a supplement, an enzyme and an herbal extract, the method comprising administering to a subject a therapeutically-effective amount of said active component simultaneously or sequentially with an adjuvant component comprising a biosurfactant.
14 . The method of claim 13 , wherein the solubility of the active component is increased.
15 . (canceled)
16 . The method of claim 13 , wherein the elimination half-life of the active component is enhanced.
17 . (canceled)
18 . A method for decreasing the latency period to achieve a maximum therapeutic concentration of an active component in a subject comprising administering to a subject a therapeutically-effective amount of said active component simultaneously or sequentially with an adjuvant component comprising a biosurfactant.
19 - 21 . (canceled)
22 . The method of claim 13 , wherein the active component is a pharmaceutical or OTC drug compound selected from one or more of daptomycin, clindamycin, azithromycin, moxifloxacin, bortezomib, lenalidomide, abiraterone acetate, pegfilgrastim, capecitabine, doxorubicin, erlotinib, aspirin, naproxen, ibuprofen, metformin, donepezil, nitazoxanide, varenicline, testosterone, sildenafil, vardenafil, tadalafil, and indinavir.
23 . The method of claim 22 , wherein the solubility of the azithromycin, moxifloxacin, bortezomib, lenalidomide, abiraterone acetate, erlotinib, aspirin, naproxen, ibuprofen, nitazoxanide, testosterone, sildenafil, vardenafil, tadalafil, and/or indinavir is increased in a formulation to be administered to the subject.
24 . The method of claim 22 , wherein the solubility of the azithromycin, moxifloxacin, bortezomib, lenalidomide, abiraterone acetate, erlotinib, aspirin, naproxen, ibuprofen, nitazoxanide, testosterone, sildenafil, vardenafil, tadalafil, and/or indinavir is increased in the subject.
25 . (canceled)
26 . The method of claim 22 , wherein the elimination half-life of clindamycin, capecitabine, metformin, nitazoxanide, and/or indinavir, is enhanced.
27 - 29 . (canceled)
30 . A method for decreasing the latency period to achieve the maximum therapeutic concentration of donepezil or any alternative form of donepezil in the cerebral spinal fluid in a subject comprising administering to a subject a therapeutically-effective amount of said donepezil or any alternative form of donepezil simultaneously or sequentially with an adjuvant component comprising a biosurfactant.
31 . The method of claim 13 , wherein the active component is a vitamin selected from vitamin A, D, E and K.
32 . The method of claim 13 , wherein the active component is cannabidiol.
33 . The method of claim 13 , wherein the active component is an enzyme selected from CoQ10 and nattokinase.
34 . The method of claim 13 , wherein use of a biosurfactant as the adjuvant component decreases or eliminates the need for use of chemical surfactants in drug and supplement formulations.
35 . The method of claim 13 , further comprising storing the active component mixed with the adjuvant component for a period of time, wherein the stability of the active component is enhanced such that the active component remains therapeutically-effective throughout storage.
36 . The method of claim 35 , wherein stability is enhanced when storage occurs at temperatures between −20° C. and 37° C.
37 . The method of claim 35 , wherein stability is enhanced by enhancing the active component's resistance to ultraviolet light degradation.
38 . A composition comprising a drug compound, a vitamin, a mineral, a supplement, an enzyme or an herbal extract, and an efficacy-enhancing amount of a biosurfactant adjuvant, wherein the drug compound, vitamin, mineral, supplement, enzyme or herbal extract has enhanced stability compared to a composition comprising the same drug compound, vitamin, mineral, supplement, enzyme or herbal extract without the biosurfactant adjuvant.
