Precision medicine aims to optimize pharmacological treatments by considering patients' genetic, phenotypic, and environmental factors, enabling dosages personalized to the individual. To address challenges associated with oral and injectable administration approaches, implantable drug delivery systems have been developed. These systems overcome issues like patient adherence, bioavailability, and first-pass metabolism. Utilizing new combinations of biodegradable polymers, the proposed solution, a Polymeric Controlled Release System (PCRS), allows minimally invasive placement and controlled drug administration over several weeks. This study's objective was to show that the PCRS exhibits a linear biphasic controlled release profile, which would indicate potential as an effective treatment vehicle for cervical malignancies. An injection mold technique was developed for batch manufacturing of devices, and in vitro experiments demonstrated that the device's geometry and surface area could be varied to achieve various drug release profiles. This study's results motivate additional development of the PCRS to treat cervical cancer, as well as other malignancies, such as lung, testicular, and ovarian cancers.
精准医学旨在通过考虑患者的基因、表型和环境因素来优化药物治疗,实现因人而异的个性化给药剂量。为应对与口服和注射给药方式相关的挑战,人们开发了可植入药物递送系统。这些系统克服了患者依从性、生物利用度和首过代谢等问题。利用可生物降解聚合物的新组合,所提出的解决方案——聚合物控释系统(PCRS),能够实现微创植入并在数周内进行可控的药物给药。本研究的目的是表明PCRS呈现线性双相控释曲线,这将表明其作为宫颈癌有效治疗载体的潜力。开发了一种注射成型技术用于批量生产该装置,体外实验表明可以改变装置的几何形状和表面积以实现各种药物释放曲线。本研究结果促使进一步开发PCRS用于治疗宫颈癌以及其他恶性肿瘤,如肺癌、睾丸癌和卵巢癌。
