[Pharmacokinetics of the new Soviet, tritium-labelled, antihistamine preparation, phencarol].

As evidenced no less than 45 per cent of tritium-labelled antihistaminic drug phencarol (quinuclidine-3-diphenylcarbinol hydrochloride) introduced intragastrically to rats is absorbed. The maximal radioactivity in various organs is reached in 1--3 hours, with high specific radioactivity being recorded in the lungs and liver and low--in the brain. The drug or radioactive products of its tranformation are eliminated largely via the gastrointestinal tract and kidneys.
