PVC is a "thermoplastic resin" having thermoreversibility, and when heated, exhibits fluidity and is easy to be molded. Since PVC itself is a relatively hard and brittle polymer, plasticizers are added to obtain the desired flexibility and durability to meet the needs of the application. In this study, focusing on the thermoplasticity of PVC, PVC and a drug-containing PVC film were prepared to evaluate their applicability as drug carriers.
DSC, FTIR, dissolution behavior of API from PVC, PVC film showed various physicochemical properties depending on the difference of TOTM content and type of model drug. The amount of drug, irogladine maleate for wound healing, released from the PVC film was different depending on the difference in thermal conditions. From these results, it was considered that the PVC film containing TOTM could be applied as a patch-type preparation capable of controlling the drug release depending on the environmental heat conditions.
