[Development of a carbamazepine determination method based on high-performance liquid chromatography with diode array].

Carbamazepine is used in the treatment of convulsive disorders, trigeminal neuralgia and mental illnesses such as bipolar disorder and pain syndromes. It has been found in clinical applications that carbamazepine causes many serious adverse drug reactions, which are associated with drug concentration in blood and dosage in clinical use. Due to its pharmacological properties, carbamazepine can be life-threatening in an overdosage, making the therapeutic drug control of carbamazepine important in any clinical settings. Creation of a method for carbamazepine quantification in biological objects during forensic chemical examinations is an urgent problem. A method of high-performance liquid chromatography with diode array detection is proposed for carbamazepine quantitation. The stability of proposed conditions for carbamazepine analysis has been proved in the modifying study conditions (flow rate of eluent, its composition, pH of buffer, column oven temperature). The relative standard deviation of retention time and areas of chromatographic peaks of carbamazepine did not exceed 0.5%.
