CROSS REFERENCE

This application claims priority from Indian Patent Application No. 202141058356 filed on December 15, 2021.

FIELD OF THE INVENTION

The present invention provides a phyto-pharmaceutical active polymolecular formulation. More particularly, the present invention provides pharmaceutical composition comprising combination of herbal powder and standardised solvent extract(s) of the herbal mixture useful for the treatment of liver disorders. The invention also provides a process for the preparation of such compositions and extraction process to enhance the active ingredients from the herbs.

BACKGROUND OF THE INVENTION

Liver is the largest organ in the human body. It is the only organ that is capable of regeneration of its cells, when damaged. Liver is involved in the process of removing all toxins that enter the body through food, water and air. Whatever is absorbed from the gastro intestinal route is first passed through the liver. Certain toxins that enter directly to the circulation system or through the lungs also reach the liver. It receives 25% of the blood pumped by the heart and acts like a filter that tests anything we eat.

The liver cells can be damaged through certain toxins. Regular consumption of alcohol, can damage the liver as it directly affects liver cells called hepatocytes. Even certain medication used to treat infections like tuberculosis can damage hepatocytes. The liver is capable of regeneration of damaged cells. This process of damage and regeneration can be detected through certain biochemistry tests done using serum, derived from blood drawn from the person. Alanine Liver Specific Transaminase (ALT), is one such enzyme that is specific to injury of liver cells or hepatic injury.

Hepatic injury can be transient, chronic or permanent. Transient happens whenever there is a toxin introduced to the body; drugs, alcohol, certain food toxins and environmental toxins. This is detected as a 1 - 2-fold increase in the ALT. the levels do come back to baseline in about 24 - 48 hours after stopping the ingestion of the toxin. If the toxin is consumed, like alcohol, for longer durations in moderate to large quantities then there is a shift in the baseline of the ALT and the enzymes can be elevated to about 2 - 3-fold. It also takes a longer duration, weeks to months, for it to recover to baseline levels. But in the case of a viral insult to the liver, like viral hepatitis, then there is massive destruction of the cells and the enzymes are increased nearly 100-fold. This will also take months to recover but still considered as transient as the viral cycles are transient. This may be different in the case of a chronic viral infection but again it depends on the virulence of the virus.

Non-alcoholic fatty liver disease (NAFLD) is when excess fat builds up in the liver due to causes other than alcohol use. There are two types: non-alcoholic fatty liver (NAFL) and non- alcoholic steatohepatitis (NASH). Non-alcoholic fatty liver usually does not progress to liver damage or NASH. NASH includes both a fatty liver and liver inflammation.

Sometimes the above insults remain for longer durations or at times the toxins are consumed in large quantities for very long periods of time, then this injury becomes chronic and leads to liver cirrhosis, liver cancer, liver failure, or cardiovascular disease. Stages of NAFLD - pathophysiology

Lifestyle is only effective in the early stages of the disease as evidenced from various guidelines prevalent at this stage. There is no consensus on the evidence from the ongoing and completed clinical trial with existing therapeutics. This gives an opportunity to bring together a novel concept “Interceptive medicine” that can support the global efforts to unifying the diagnosis criteria, prognosis criteria and treatment criteria.

There are certain herbal based products in the market currently which claims to be liver protective and/or kidney protective compositions. Such compositions comprise either multiple number of herbal components examples being LIV®-52 tablets, Bioliv syrup, Biolive syrup or compositions that is herbal powder mixture which does not constitute extract based components example being Liver Kidney Care™ capsules.

Compositions that have lower number of herbal components with optimized mixture of whole herb constituents and extract based constituents which could be effective against NAFLD is desirable. Compositions of the present invention are an optimized mixture of whole herb constituents and extract based constituents and is a whole new genre of interceptive management for this chronic condition. Particularly, in the early stages of the disease - first to third that render a standard of care for intercepting the onset and progression to various stages of Non-alcoholic fatty liver disease (NAFLD).

Compositions of the present invention are an effective combination of whole herbal powder and extract based constituents that delivers standard doses of three herbs that is able to reduce fatty infiltration of hepatocytes (liver cells), promotes faster healing and reduce rate of cell death and thus capable of improving liver recovery from an acute or a chronic insult by liver toxins.

The present inventors have developed a unique method to combine the whole herbs and extracts of the same that enhances the active ingredients from the herbs. This not only retains the safety of the product, increases the efficacy and also ensures compliance to regulatory requirements for drug development as a botanical drug. The inventors of the present invention have identified a polymolecular cluster of 4 compounds responsible for the efficacy from the extracts.

The instant invention thus provides a composition that aids in liver recovery from acute and sub-acute insults from known liver toxins, faster than the natural recover phase seen when the insult is stopped. Further the instant composition has hepato -protective ability to prevent liver cells to go into permanent structural changes like fibrosis and death. The instant composition in humans, when consumed in the right dose for a given period of time, fasten the healing process and protect the liver cells from death and fibrosis. Further the instant extraction process enhances the active ingredients from the herbs and provides efficacy to the composition.
