Abstract: Women's health is extremely important and is directly related to the social health of the family. Gynecological care should always be carried out with the aim of providing women with a healthier life. Considering some of the gynecological diseases that affect women, intrauterine devices (IUDs) made from polyethylene, acyclovir and silver sulfadiazine were selected as study objects. IUDs have been successfully manufactured using the injection molding process. Through scanning electron microscopy analyses, it was possible to verify that all samples presented have good surface quality regardless of the percentage of drug added, and an EDS analysis confirmed the presence of drugs in the sample compositions. Infrared spectroscopy analyzes confirm the composition of the polymer used and the drugs. The differential exploratory calorimetry test of HDPE IUD samples with acyclovir made it possible to identify the melting temperatures of HDPE and the drug, proving their constitution. In HDPE samples with silver sulfadiazine, it was not possible to identify the transitions related to this drug. The addition of the drug to its composition did not result in such a significant influence on its mechanical properties, which is positive from the product's point of view. HDPE IUDs with acyclovir were an initial rapid release of the drug. HDPE IUDs with silver sulfadiazine offered rapid initial release, but in smaller quantities. Multidrug IUDs presented an acyclovir release profile very similar to the IUD with only acyclovir, while the release of silver sulfadiazine was reduced. Injection molding is an advantageous molding process for manufacturing this type of device, resulting in parts with mechanical and aesthetic quality. Finally, it was found that the drug concentration may be higher in planning and in the actually manufactured part, or that it is interesting at the technological level to manufacture injection molded implants with large amounts of drug percentage.
