The proposed methods are new, simple, precise and accurate derivative spectroscopy and area under curve method was developed for the estimation of Apremilast in bulk and in-house tablets. Apremilast is phosphodiesterase-4 inhibitor; soluble in methanol. In this paper four simple Spectrophotometric methods were used for estimation of Apremilast, the proposed study was performed on double beam UV-VIS Spectrophotometer (UV-2450, Shimadzu, Japan). Apremilast was directly determined at 230 nm. The methods obey Beer's law in the range of 2–12 μg/mL, where the accuracy was found to be in the range of 98–101%. Furthermore the precision of methods were calculated in terms of % RSD less than 2 shows methods were precise. The developed methods were validated according to ICH guidelines. The described methods can be routinely used for determination of Apremilast in bulk and pharmaceutical formulations.
