Abstract
OBJECTIVES
To compare the effect of Parlodel SRO (Sandoz, Basel, Switzerland), a long-acting oral bromocriptine, to Parlodel (Sandoz) and to study the chronic effects of Parlodel SRO.
DESIGN
The study was twofold: (1) random, double-blind and (2) open.
SETTING
Patients were studied in an academic environment.
PATIENTS
Hyperprolactinemic patients were selected. Sixteen patients were treated during 1 month. Ten patients completed the 1-year follow-up.
INTERVENTIONS
Parlodel SRO or Parlodel was administered during 1 month (first 15 days: 5 mg/d; afterwards: 10 mg/d). Parlodel SRO was given during 1 year in variable doses (maximal 20 mg/d).
MAIN OUTCOME MEASURES
Prolactin (PRL) levels, clinical improvement, and side effects were evaluated.
RESULTS
After 1 month, 63% of the patients in both groups had normal PRL and 43% had menses. Side effects were similar. After 1 year all patients except one had normal PRL levels, and 89% were ovulating.
CONCLUSIONS
The efficacy, tolerability, and long duration of action of Parlodel SRO make it an excellent alternative for the treatment of hyperprolactinemic patients.
