Triptorelin depot is largely used to treat central precocious puberty (CPP) in children. Areas covered: This review updates triptorelin depot treatment of CPP, focusing on trials that compared 3.75 mg/28 day treated and untreated children till the adult height (AH). Efficacy of the new 11.25 mg/90 days or 22.5 mg/6 month formulations in suppressing pituitary-gonadal axis in short-term trials is also addressed. Short- and long-term safety was summarized. Expert commentary: Long experience on triptorelin depot use in children with CPP is available. Outcome differences on AH are reported; they may be due to heterogenicity of treated patients; some items remain to be optimized. No long term-adverse events on reproductive function are reported; additional studies would clarify if CPP per sè or triptorelin depot administration may increase hyperandrogenism and/or polycystic ovary syndrome risk in adulthood. The quarterly formulation seems to be able to suppress pituitary-gonadal axis and pubertal development and to determine similar end-results as monthly formulation, but additional trials are needed. Few data are available for the 22.5 mg/6 month formulation. Triptorelin depot treatment of CPP should be restricted to tertiary pediatric endocrinology centers, considering that some uncertainties still exist and that rare but serious adverse events may occur.
