No, actually quite the opposite. Phenobarbital enhances conjugation of bilirubin in the liver by inducing microsomal enzymes, like UDP-glucuronyl transferase.

What is the etiology of hyperbilirubinemia?
Hyperbilirubinemia can be caused by an increase in the production of bilirubin, decreased conjugation of bilirubin in the liver, impaired uptake of bilirubin by liver cells, or decreased excretion of bilirubin into bile. Common causes include hemolysis, liver disease, and obstruction of bile flow.
Can jaundice be prevented?
the activity of the enzyme UDP-glucuronyl transferase is low in the newborns.so UDP- glucuronic acid for conjugation is limited. this leads to high level of unconjugated bilirubin (beyond 25mg/dl) .it may cross the blood brain barrier resulting in hyperbilirubinemic toxic encephalopathy or kernicterus . prevention aspects: the drug phenobarbital is used, as it induce bilirubin metabolising enzymes in liver. in some neonates blood transfusion may be necessaryto prevent brain damage. phototherapy is continuously carried out till the serum bilirubin becomes normal. phototheraphy deals with the exposure of the jaundiced neonates to blue light as bilirubin absorbs the blue light and get converted to non toxic lumirubin and get excreted.

What is methyl phenobarbital?
Prodrug for Phenobarbital.
What is TBIL on a blood test?
Bilirubin is a breakdown product of heme (a part of haemoglobin in red blood cells). The liver is responsible for clearing the blood of bilirubin. It does this by the following mechanism: bilirubin is taken up into hepatocytes, conjugated (modified to make it water-soluble), and secreted into the bile, which is excreted into the intestine. Increased total bilirubin causes jaundice, and can signal a number of problems: 1. Prehepatic: Increased bilirubin production. This can be due to a number of causes, including hemolytic anemias and internal hemorrhage. 2. Hepatic: Problems with the liver, which are reflected as deficiencies in bilirubin metabolism (e.g. reduced hepatocyte uptake, impaired conjugation of bilirubin, and reduced hepatocyte secretion of bilirubin). Some examples would be cirrhosis and viral hepatitis. 3. Posthepatic: Obstruction of the bile ducts, reflected as deficiencies in bilirubin excretion. (Obstruction can be located either within the liver or in the bile duct.)
How is phenobarbital classified?
Phenobarbital is recommended to treat epilepsy.
What color tube for a phenobarbital level?
Phenobarbital level
What are the pigments released by the liver in bile called?
From the glossary of medical terms the answer is: BILIRUBIN
What is the meaning of phenolarbital?
The correct spelling is phenobarbital instead of phenobarbital. Phenobarbital is a sedative barbiturate drug. It is a narcotic that is typically used in the treatment of epilepsy.
What is the color of bilirubin?
The color of Bilirubin is orange Bilirubin is an orange color pigment in the bile
End product of hemoglobin breakdown is?
bilirubin
Pigment produced by the destruction of hemoglobin in the liver is called?
When the erythrocytes are destroyed, haemoglobin breaks down, the heme part of it goes through a series of transformation: Heme → biliverdin (green pigment) biliverdin → bilirubin (orange-yellow pigment) Bilirubin + blood albumin → bound bilirubin (in peripheral blood) Bound bilirubin + glucuronic acid → conjugated bilirubin. (in liver) Conjugated bilirubin + intestinal bacteria → several pigments, including - stercobolin (orange-brown pigment, excreted in feces) and - urobilinogen (reabsorbed into bile/blood, finally excreted in urine)
