In Situ Photo Responsive Biodegradable Nanoparticle Forming Intrauterine Implant for Drug Delivery to Treat Ovarian Diseases: A Rationale-based Review

Background: Ovarian disease constitutes various types of endocrine disorders, such as polycystic ovarian syndrome (PCOS), ovarian cancer, premature ovarian failure, ovarian endometriosis, and ovarian cysts. The prevalence of ovarian-related diseases is highly vulnerable in the world. The utility of various drug delivery systems for ovarian diseases has resulted in varied success. Moreover, most of them lead to severe adverse effects and are incapable of ameliorating the signs and symptoms of the condition. Hypothesis: Intrauterine devices (IUDs) have positioned themselves as a mechanism to deliver the drug for various ovarian-related diseases. Thereby avoiding various stability-related issues arising due to various physiological barriers of the female reproductive tract. However, the use of intrauterine devices for drug delivery to the ovaries has not been fully explored. This is attributed to the fact that they cause cysts in the ovaries and skepticism among patients and physicians. Photo-sensitive devices are an appealing approach for managing disorders affecting the ovaries. Photo-sensitive in situ forming intrauterine implants (IUIs) have several advantages, including simplicity in application, reduced invasiveness, as well as improved site-specific drug release control. Polymeric nanoparticles (PNPs) loaded with a drug may be a suitable choice to provide sustained release, alter the pharmacokinetics, and reduce the dose and dosing frequency. Conclusion: The current manuscript hypothesizes the utility of a PNP-loaded biodegradable photo-responsive intrauterine implantable device as an alternate novel strategy for ameliorating ovarian-related diseases.
