[Phenobarbital--an inducer of bilignost excretion with the bile in rats]

It was found that a preliminary administration of phenobarbital to rats caused an increase of the rate of 125I-bilignost excretion in the bile by 46.6% but reduced its half-life in the blood by 48.3% and its excretion in the urine by 46.4%. Phenobarbital decreased the rate of 125I-bilignost absorption by the liver slices and increased the rate of release from them.
