title: No effect of bromocriptine in acromegaly: a controlled trial.
abstract: Although bromocriptine, a dopamine receptor agonist, is now widely used in the treatment of acromegaly, there have been no controlled trials of its biochemical or clinical effects on this disorder. We assessed its effects in a double-blind, crossover study. Eighteen patients with acromegaly were given bromocriptine and placebo alternately for three months per medication. Their responses to oral glucose-tolerance tests during the two regimens did not differ significantly. The number of patients noting amelioration of clinical symptoms during treatment with bromocriptine was almost identical to the number with clinical improvement during placebo. We conclude that it remains doubtful whether bromocriptine has a beneficial effect in acromegaly.
