Objective: A transdermal hydrogel dosage form consists of a three-dimensional polymer network that binds water in large quantities and is usedfor drug delivery. The study’s aim was to prepare coprocessed excipients as a matrix for a transdermal hydrogel containing diclofenac sodium andexamine in vitro and in vivo drug penetrations.Methods: Four types of coprocessed excipients were produced using two methods that combined crosslinking and coprocessing steps. The producedexcipients were formulated as transdermal gels containing sodium diclofenac. An in vitro penetration test was then performed using a Franz diffusioncell to pass the drug through a rat skin membrane. An in vivo penetration test was performed by applying the hydrogel to the abdominal skin of maleSprague-Dawley rats and then measuring the plasma drug concentration.Results: In vitro penetration results showed that the flux from Co-CLA6-XG 1:2, Co-CLA12-XG 1:2, CL6-Co-A-XG 1:2, and CL12-Co-A-XG 1:2 transdermalhydrogels was 655.23±116.43 μg∙cm−2/h, 569.08±26.58 μg∙cm−2/h, 867.42±101.27 μg∙cm−2/h−1, and 736.99±15.39 μg∙cm−2/h−1. The in vivo studyresulted in area under the curve for the Co−CLA6−XG 1:2, Co−CLA12−XG 1:2, CL6−Co−A−XG 1:2, and CL12−Co−A−XG 1:2 transdermal hydrogels was32.08±5.40 μg∙ml−1∙h, 34.27±8.34 μg/ml∙h, 6.20±2.90 μg/ml∙h, and 14.38±2.38 μg/mL∙h, respectively.Conclusion: The study results showed that the excipients could be processed to form a matrix within a transdermal hydrogel formulation and deliversodium diclofenac into systemic circulation in a controlled release manner.
