History
Chenodeoxycholic acid is a bile acid synthesized in the liver from cholesterol.
Chenodeoxycholic acid was isolated in 1924 from goose gall by Adolf Windaus and
human gall by Heinrich Wieland.Its complete structural configuation was elucidated
by Hans Lettre at the University of Gottingen.
In 1968, William Admirand and Donald Small at Boston University Medical School
established that it was then found that biliary levels of cholic acid and
chenodeoxycholic acid were lower in patients with cholesterol gallstones than in
normal people. And then the national collaborative study in the United States, which
confirmed the effectiveness of chenodeoxycholic acid in bringing about dissolution of
gallstones in selected patients. However, recent developments such as laparoscopic
cholecystectomy and endoscopic biliary techniques have curtailed the role of
chenodeoxycholic acid and ursodeoxycholic acid in the treatment of cholelithiasis.
In 1978, chenodeoxycholic acid was introduced to the European market as the 7α
isomer of ursodeoxycholic acid. From 2010 to 2018, chenodeoxycholic acid was
approved for the treatment of cerebral tendon xanthomatosis.
While many other benefits of chenodeoxycholic acid have yet to be proven by
research, large-scale clinical trials have demonstrated the drug's safety and efficacy.
And it was the first drug to be introduced into the U.S. market for the treatment of
light-transmitting gallstones.

What is Chenodeoxycholic Acid(CDCA) Powder?
Chenodeoxycholic acid powder (3α,7α-dihydroxy-5-β-cholanic acid, CDCA) is one of
the major bile acids synthesized from cholesterol in the liver of humans and animals.
It was originally isolated from the bile of domestic geese, hence the name "cheno". It
was the first drug introduced to the US market for the treatment of light-transmitting
gallstones.
As a hydrophobic primary bile acid naturally occurring in the body, chenodeoxycholic
acid activates nuclear receptors (FXRs) involved in cholesterol metabolism. It dissolves
cholesterol that causes gallstones and inhibits cholesterol production in the liver and
intestinal absorption, which can help reduce gallstone formation. When bile acid
levels are elevated, it can also reduce the amount of other bile acids that are harmful
to liver cells.
Chenodeoxycholic acid is also the epimer of ursodeoxycholic acid (DB01586) and has
similar efficacy to ursodeoxycholic acid in the treatment of gallstone disease.
Chenodeoxycholic acid has been studied and evaluated as a long-term replacement
therapy for cerebral tendon xanthoma (CTX). It has also been used to study its effect
on the intestinal absorption of bile acids in ileostomy patients.

Where Does The Chenodeoxycholic Acid Powder Come From?
Chenodeoxycholic acid is the main organic constituent in the bile of chickens, ducks,
geese and other poultry. It can be extracted from poultry bile by extraction
technology or synthesized from cholic acid, dehydrocholic acid, etc. Originally, the
synthesis of chenodeoxycholic acid (CDCA) from cholic acid(CA) was the main source
of CDCA.
In Europe, chemical synthesis of CDCA from CA is the main source of CDCA. In the
past 10 years in my country, the extraction of CDCA from chicken bile is the main
source of CDCA. Although the number of chickens and ducks in China is very large,
the extraction of CDCA from chicken and duck gallbladder requires different
techniques due to the large differences in the composition of chicken and duck
gallbladder. The method of extracting CDCA from duck bile is rarely reported in the
literature.
Chenodeoxycholic Acid Powder Mechanism of Action
Chenodeoxycholic acid is a primary bile acid synthesized by the human liver, and it
can inhibit the synthesis of cholesterol and bile acid in the liver, gradually replacing
the latter and its metabolite deoxycholic acid in the expanded bile acid pool. These
actions contribute to desaturation of bile cholesterol and progressive dissolution of
radiolucent cholesterol gallstones in the presence of the gallbladder revealed by oral

5
cholecystography. Bile acids can also bind to the bile acid receptor (FXR), which
regulates bile acid synthesis and transport.
The Benefits & Effects of Chenodeoxycholic Acid Powder
Chenodeoxycholic acid is a bile acid synthesized from cholesterol in the liver, and it
has significant anti-inflammatory, antitussive, and expectorant effects. In addition,
CDCA powder has the following potential benefits for the human body:
- Can reduce or dissolve cholesterol stones in the body
- Improve the composition of bile
- For the treatment of cerebral tendon xanthomatosis
- Drug therapy for metabolic diseases
- For the treatment of various acute and chronic liver diseases
It is important to note in the treatment of gallstones that chenodeoxycholic acid is
primarily used to dissolve gallstones in people who cannot have gallbladder surgery.
Drug Interactions of Chenodeoxycholic Acid Powder
Although chenodeoxycholic acid is effective in treating or preventing cholesterol
stones diseases, it may be a interaction with other drugs (including prescription and
over-the-counter drugs, vitamins and herbal products) when used together. Therefore,
before using chenodeoxycholic acid, tell your doctor about all medicines you are
currently using and any medicines you start or stop using, especially:

6
- cholestyramine;
- Colestipol;
- cyclosporine and sirolimus
- Phenobarbital
- Birth control pills or hormone replacement therapy;
- Aluminum-containing antacids - Almacone, Gelusil, Maalox, Mag-al Plus, Mylanta,
Rulox, etc.;
- Blood thinners - warfarin, coumarin, yantovin.
The above is just a short list of drugs. Therefore, it is best to check with your doctor or
pharmacist before giving any prescription medicine.
Ursodeoxycholic Acid Powder VS Chenodeoxycholic Acid Powder
Both Ursodeoxycholic acid and chenodeoxycholic acid are one of the bile acids in bile,
and chenodeoxycholic acid is also the epimer of Ursodeoxycholic acid. They have
their own unique advantages, but in some ways their efficacy is similar.
(1)Definition
Ursodeoxycholic acid powder
Ursodeoxycholic acid(UDCA; also known as ursodiol) is a secondary bile acid that is
metabolized by gut bacteria in humans and most other species. It is synthesized in
the liver of some species and was originally found in bear bile, which is where its

7
name Ursus comes from.
Chenodeoxycholic acid powder
Chenodeoxycholic acid (CDCA; also known as chenodesoxycholic acid, chenocholic
acid and 3α,7α-dihydroxy-5β-cholan-24-oic acid) is a bile acid. Salts of this carboxylic
acid are called chenodeoxycholates. Chenodeoxycholic acid is one of the main bile
acids. It was first isolated from the bile of the domestic goose, which gives it the
"cheno" portion of its name.
(2)Benefits&functiion
Commonality
Ursodeoxycholic acid powder and chenodeoxycholic acid powder are both bile acids,
both used to treat gallstones in people who cannot have gallbladder surgery. They are
not effective in patients with calcified gallstones or a non-functioning gallbladder.
Difference
Ursodeoxycholic acid powder is a hydrophilic secondary bile acid naturally found in
human bile in small amounts (less than 4% of total bile acids). It was first introduced
in the 1970s to dissolve radiolucent gallstones and is the only drug approved by the
U.S. Food and Drug Administration for the treatment of PBC. UDCA is more
hydrophilic than other bile acids such as chenodeoxycholic acid and deoxycholic acid.
Its absorption (3-60% after oral administration) occurs primarily in the small intestine,

8
and its presence reduces cholesterol secretion into bile, possibly reducing its
conversion to bile acids. Collectively, the mechanism of action of UDCA in PBC is
based on alterations in bile acid pools, reductions in pro-inflammatory cytokines, and
effects on apoptosis and vasoactive mediators.
Chenodeoxycholic acid is a hydrophobic primary bile acid, an epimer of UDCA,
synthesized in the liver and present in bile at high concentrations for the dissolution
of cholesterol gallstones. It is most effective for small "floating" gallstones.
Chenodeoxycholic acid was approved in 1983 for patients with light-transmitting
gallstones and is still available, although it has largely been seen as more effective
and well-tolerated Better chenodeoxycholic acid substitution. In addition, it is used to
treat cerebral tendon xanthomatosis. It has been studied as a possible treatment for
constipation and has been shown to speed up colonic transit and improve bowel
function.
The Side effects of Chenodeoxycholic Acid Powder
In addition to its desired effects, chenodeoxycholic acid powder may cause some
adverse effects. Although not all of these side effects can occur, if they do occur, they
may require medical attention.
If any of the following side effects occur, consult your doctor immediately:

9
Serious side effects may include:
- Signs of an allergic reaction (eg hives; difficulty breathing; swelling of the face, lips,
tongue or throat, etc.)
- Worsening or no improvement of gallstone symptoms;
- Severe or persistent diarrhea;
- Liver problems - loss of appetite, upper abdominal pain, tiredness, easy bruising or
bleeding, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
Common side effects may include:
- Mild stomach cramps
- Gastrointestinal discomfort
- Diarrhea
- Bloating
- Indigestion
- Nausea and vomiting
- Abnormal blood tests (low white blood cells, high cholesterol or triglycerides)
This is not a complete list of possible side effects. If you notice other effects not listed
above, contact your doctor or pharmacist or suppliers.
Where is Chenodeoxycholic Acid Powder Sold?
Chenodeoxycholic acid powder wholesale trades are much more common than retail

10
sales as it is usually purchased in bulk directly from the Chenodeoxycholic Acid
Powder manufacturer factory. Generally, medications of such private nature are
commonly bought online as it provides patients with discretion and privacy that they
need. And maybe you can find it at your local pharmacy, usually in tablet and capsule
form. But whether you buy it online or pharmacy, you should take care to take the
appropriate dose as recommended by your supplier or doctor, and should not be
missed or overdose.
