Simultaneous thin-layer chromatography-densitometric analysis of sibutramine and citalopram

Due the presence of sibutramine and citalopram in a number of drugs, neurotransmitter reuptake inhibitors. Sibutramine reduces the reuptake of serotonin, norepinephrine, and dopamine; citalopram is an antidepressant drug of the selective serotonin reuptake inhibitor. The thin-layer chromatography-densitometric behavior of some centrally acting serotonin reuptake inhibitors has been studied. The proposed analytical method is suitable for qualitative and quantitative analysis of sibutramine and citalopram.
