The present invention relates to a composition comprising phytochemicals and bio-enhancing agents/self-dispersing agents derived from fresh plant parts, wherein said composition enhances the self-dispersion and bioavailability of phytochemicals. The present invention also relates to a process for preparation of said composition.
Herbal medicine has made a major contribution to the drug discovery process and its use has increased worldwide due to their therapeutic effects and fewer adverse effects as compared to the modern medicines. Many herbal drugs and herbal extracts, however, despite their effective in-vitro findings demonstrate less or negligible in-vivo activity due to their poor solubility/dispersibility resulting in poor absorption and hence poor bioavailability leading to poor or decreased efficacy.
The phytochemicals with poor bioavailability in plant extracts belong to category of phenolic compounds, xanthophyllic carotenoids, carotenoids, protoberberine group of benzylisoquinoline alkaloids, stilbenoids, isoflavones, monoamine alkaloids, flavonols and many others which have proven to have several therapeutic benefits like anti-inflammatory, anti-oxidant, age-related macular degeneration, anti-cancerous, memory enhancing among many other medicinal activities. However, very less has been achieved with respect to said phytochemicals for prevention and treatment of diseases due to their poor intestinal absorption and bioavailability.
The further developments in the art observed that the main issue which needs to be addressed with the phytochemicals is not only the bioavailability but also their availability in the systemic circulation for longer period of time in biologically active form for sustained efficacy. This will also help in reducing the dosages thus making the treatment cost effective, minimize drug toxicity and is patient compliant.
Bioavailability enhancing activity of natural compounds have several mechanisms of action and is mainly attributed to mechanisms such as P-glycoprotein (P-gp) inhibition activity, non-specific mechanisms promoting rapid absorption of drugs such as increased blood supply to the gastrointestinal tract, decreased hydrochloric acid secretion, non-specific mechanisms inhibiting enzymes participating in metabolism of drugs to list the few.
‘Bioavailability enhancers’ are facilitators capable of increasing the intestinal absorption, enhancing bioavailability and bio-efficacy of a particular drug or phytochemical with which it is combined, without any typical pharmacological activity of its own at the dose used.
The term ‘bioavailability enhancer’ was first coined by Indian scientists at the Regional Research Laboratory, Jammu (RRL, now known as Indian Institute of Integrative Medicine, Jammu), who discovered and scientifically validated piperine as the world's first bioavailability enhancer in 1979 [Atal C K. A breakthrough in drug bioavailability-a clue from age old wisdom of Ayurveda. IDMA Bulletin. 1979; 10:483-484].
The use of herbal bio-enhancers is widely appreciated as a means for bioavailability enhancement because these are safe, non-toxic, economical, easily procured, pharmacologically inert and non-allergenic in nature.
WO03/049753 relates to a bio-enhancing composition containing extract and/or bioactive fraction/isolate from the plant Zingiber officinale in combination with drugs, nutrients, nutraceuticals, micronutrients and herbal drugs/products and optionally containing piperine as a extract/active fraction (solvent extract) obtained from Piper nigrum, Piper longum or its oleoresin as a bioavailability enhancer and its process for producing the extract or fractions from the plant source.
U.S. Pat. No. 5,536,506 discloses use of piperine to increase the bioavailability of nutritional compounds. US'506 further discloses a composition and method for the improvement of gastrointestinal absorption and systemic utilization of nutrients and nutritional supplements, wherein the composition comprises an solvent extract from the fruit of Piper containing a minimum of 98% of pure alkaloid piperine.
WO2015/025263 discloses a composition containing curcumin along with soluble proteins, dietary fiber, fixed oil and essential oil from turmeric that increases absorption of curcumin in the blood and results in better dispersibility upon oral consumption, which is useful for treatment of various diseases.
Article titled, “Bioavailability enhancing activities of natural compounds from medicinal plants” by Myung Joo Kang et. al., published in Journal of Medicinal Plants Research Vol. 3(13), pp. 1204-1211, December, 2009 disclose the natural compounds such as quercetin, genistein, naringin, sinomenine, piperine, glycyrrhizin and nitrile glycoside for improving the drug bioavailability.
Though bio-enhancers in drug delivery are known, challenge still persists to provide safe herbal bio-enhancers for increasing the bioavailability of herbal origin/phytochemicals that are non-toxic, non-irritating, rapid acting with predictable activity. Natural bioenhancers produced using solvent free process are preferred over the bioenhancers produced using solvent extraction due to the adverse effect of residual solvents. Another problem encountered in the art is large scale production of such formulations containing the herbal compound and the bio-enhancer.
In view of the shortcomings of the art, the object of the present invention is to provide a potential solution for enhancing the bio-availability of phytochemicals using bio-enhancing/self-dispersing agents derived from solvent free extract of fresh plant parts.
To achieve the above objective, in an aspect, the present invention provides a composition for enhancing the self-dispersion, intestinal absorption and bioavailability of phytochemicals comprising;
In another aspect, the present invention provides a process for preparation of the composition for enhancing the self-dispersion, intestinal absorption and bioavailability of phytochemicals comprises the steps of;
The present invention will now be described in detail in connection with certain embodiments, so that various aspects thereof may be fully understood and appreciated.
