Dear Rasaq, Raised CPK and neuroleptic malignant syndrome have been well described in patients taking neuroleptic drugs. We recently had a patient taking Olanzipine with a CPK of 58,000 u/L but without symptoms of NMS (however with severe hyponatraemia) , and found two case reports of raised CPKs associated with neuroleptic drugs without symptoms of NMS.

In addition to Olazipine, the patient has also been taking creatine phosphate for body building purposes. The creatine phosphate was not prescribed by any practitioner. In order to find the possible cause of the raised CK, both medications were stopped, and 3 days later, the CK levels were back to normal (117)! The pertinent question is: Does anyone have any experience with high CK following prolonged administration of creatine phosphate or, could this be due to olazipine Many thanks Dr Rasaq Olufadi Please reply to: [log in to unmask] <mailto:[log in to unmask]> ------ACB discussion List Information-------- This is an open discussion list for the academic and clinical community working in clinical biochemistry.
