A pharmacological evaluation of a new 3-month depot preparation of buserelin for prostatic cancer.
A new slow-release formulation of buserelin given as a 3-month depot injection was evaluated in four patients with advanced prostatic cancer. Treatment was maintained for a mean period of 15 months. Steady-state urinary buserelin concentrations were reached by the beginning of the 3rd week of treatment and maintained until the end of the 3rd month. Serum testosterone remained suppressed in the castrate range for the duration of the study. This preparation offers an advantage for the patient and clinician over existing methods of gonadotrophin-releasing hormone (GnRH) analogue administration and will enter further clinical trial.
