[Initial experiences with implanted drug pumps for continuous intrathecal calcitonin therapy in therapy-resistant pain].

The hormone calcitonin has proved itself for some years in the treatment of chronic pain syndromes. In addition to its known influence on calcium exchange it gives vise to an analgesic effect within the central nervous system and this follows systemic administration or after bolus intrathecal injection. Two patients with chronic non malignant pain are presented in whom continuous delivery pumps have been used for intrathecal Lachs-Calcitonin (Karil, Fa. Sandoz).
