Effects of Different Dosages of Bromocriptine on Clinical Efficacy of Prolactinoma,Serum Level of PRL and Tumor Volume / 中国药房

ABSTRACT

OBJECTIVE:To investigate clinical efficacy and safety of different dosages of bromocriptine in the treatment pro-lactinoma,and its effects on serum prolactin(PRL)and tumor volume. METHODS:A total of 60 patients with prolactinoma were selected from our hospital during Jan.-Dec. 2015 as research objects,and then divided into group A and B according to random number table,with 30 cases in each group. Both groups were given Bromocriptine mesilate tablets orally during meal. Group A was given medicine with initial dose of 2.5 mg/d,increasing to 3.75 mg/d 3 d later,increasing by 2.5 mg every week after 2-3 d,and then recovering to 3.75 mg/d till serum PRL level had been controlled. Group B was given medicine with initial dose of 1.25 mg/d, increasing to 2.5 mg/d 3 d later,increasing by 1.25-2.5 mg every week after 2-3 d,and then recovering to 2.5 mg/d till serum PRL level recovered to normal. Both groups were treated for consecutive 3 months. Clinical efficacies as well as serum level of PRL and tumor size were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:The total response rate of group A (83.33％) was higher than that of group B (66.67％),without statistical significance (P>0.05). Before treatment,there was no statistical significance in serum level of PRL and tumor size between 2 groups (P>0.05). After 1,2 months of treatment,serum levels of PRL in 2 groups were decreased significantly,and the group A was significantly lower than the group B,with statistical significance(P0.05). After treatment,tumor size of 2 groups were decreased significantly,and large adenoma and giant adenoma size in group A were significantly smaller than group B,with statisti-cal significance(P0.05). The inci-dence of ADR in group A(12 cases,40.00％)was significantly higher than group B(5 cases,16.67％),with statistical signifi-cance(P<0.05). CONCLUSIONS:Increasing dosages of bromocriptine no significant influence on therapeutic effect of prolactino-ma,but it can shorten the time of serum PRL level back to normal,and reduce the tumor size. The incidence of adverse reactions in-crease with the dosage.
