Abstract

The aim of this study is to compare the clinical and biochemical outcomes of triptorelin acetate (TPA) versus triptorelin pamoate (TPP) treatment in girls with central precocious puberty. A total of 60 patients with idiopathic CPP were retrospectively recruited. Thirty girls were treated with triptorelin acetate 3.75 mg/month (TPA group) and thirty girls in a second group received triptorelin pamoate 3.75 mg/4 weeks (TPP group). Patient follow-up at 12 and 24 months included GnRH Test at 12 months and baseline LH at 24 months. Patients were monitored with pelvic ultrasound, X-Ray of the hand and wrist and anthropometric evaluations. A total of 60/60 girls showed a good response to both formulations. Significant reductions in basal and LH peaks, estradiol values, breast pubertal stage, progression of bone age and growth velocity rate after 12 months treatment were obtained in both groups, demonstrating the equivalence of the two formulations in regulating the hypothalamic–pituitary-gonadal (HPG) axis. Triptorelin pamoate provided a more effective and significant reduction in LH peak after 12 months in comparison with triptorelin acetate more effective in reducing ovarian volume and endometrial thickness. Both formulations were equivalent, even though the LH peak was significantly lower in girls treated with triptorelin pamoate.
