A new oral slow release form of bromocriptine, Parlodel SRO, in the chronic treatment of 26 hyperprolactinemic patients.

Parlodel SRO, a new slow release form of bromocriptine, was studied in 26 patients with tumoral and non-tumoral hyperprolactinemia. Prior to the treatment, serum prolactin (PRL) levels ranged from 45 ng/ml to 7000 ng/ml and they decreased to within the normal range in all but one patient after 7 days-1 year of treatment with this new formulation of bromocriptine. The clinical improvement paralleled the normalization of PRL secretion. Tolerability was rated good or very good in 24 patients, even in the three patients who had been intolerant of oral Parlodel. In conclusion, Parlodel SRO administered as a single daily dose resulted in very effective lowering of serum PRL in patients with hyperprolactinemic disorders.
