Agomelatine release from DLP 3D printed ethanol gel-coated cone microneedle systems

Raw data from release studies of agomelatine (AGM) from microneedle systems.

Microneedle system specifications:

• 3D printing method: Digital Light Processing (DLP)
• microneedle shape: Cone
• coating-gel type: ethanol gel

Drug release studies: The permeation of agomelatine (AGM) was evaluated using Franz Diffusion Cells (Teledyne Hanson 376 Research, USA) without using any membrane.

Quantification of AGM: The amount of AGM permeated was analyzed using High-Performance Liquid Chromatography (HPLC) (Shimadzu Nexera-I LC-2040C, Japan) with LabSolution Lite software.

• Chromatographic Conditions:Column: Reversed-phase C18 (HyperClone BDS C18, 5 µm, 4.6 × 250 mm, Phenomenex, Torrance, CA, USA)
• Column Temperature: 30.0 ± 0.2°C
• Mobile Phase: Acetonitrile and 0.05 M potassium dihydrogen phosphate solution (pH = 2.9, adjusted with 85% orthophosphoric acid) in a 35:65 ratio
• Mode: Isocratic
• Flow Rate: 1.0 mL/min
• Detection Wavelength: 230 nm

The set contains data in LCD/ LCB format, created using the LabSolutions software (HPLC, Nexera LC 2040C). Data file (.lcd) contains all analysis results and acquisition information from the following files. Data in .txt format can be read without the need for LabSolutions software.
