title: Clinical usefulness of cimetidine for the treatment of acute intermittent porphyria--a preliminary report.
abstract: A 43-yr-old man with abdominal fullness was treated with oral cimetidine during remission of acute intermittent porphyria. Urinary prophobilinogen and porphyrins were not altered by the treatment, but urinary delta-aminolevulinic acid decreased, and abdominal fullness disappeared. Thus, cimetidine may control acute intermittent porphyria by inhibiting hepatic delta-aminolevulinic acid synthetase.
