Abstract
Due to the specific physiological pH throughout the human body, pH-responsive polymers have been considered for aiding drug delivery systems. Depending on the surrounding pH conditions, the polymers can undergo swelling or contraction behaviors, and a degradation mechanism can release incorporated substances. Additionally, polyurethane, a highly versatile polymer, has been reported for its biocompatibility properties, in which it demonstrates good biological response and sustainability in biomedical applications. In this review, we focus on summarizing the applications of pH-responsive polyurethane in the biomedical and drug delivery fields in recent years. In recent studies, there have been great developments in pH-responsive polyurethanes used as controlled drug delivery systems for oral administration, intravaginal administration, and targeted drug delivery systems for chemotherapy treatment. Other applications such as surface biomaterials, sensors, and optical imaging probes are also discussed in this review.

Abstract
The foremost common natural polymers are carbohydrate-based polymers or polysaccharides, having a long chain of monosaccharide or disaccharide units linked together via a glycosidic linkage to form a complex structure. There are several uses of carbohydrate-based polymers in biomedical sector due to its attractive features including less toxicity, biocompatibility, biodegradability, high reactivity, availability, and relatively inexpensive. The aim of our study was to explore the synthetic approaches for the preparation of numerous carbohydrate-based polyurethanes (PUs) and their wide range of pharmaceutical and biomedical applications. The data summarized in this study shows that the addition of carbohydrates in the structural skeleton of PUs not only improve their suitability but also effect the applicability for employing them in biological applications. Carbohydrate-based units are incorporated into the PUs, which is the most convenient method for the synthesis of novel biocompatible and biodegradable carbohydrate-based PUs to use in various biomedical applications.

Abstract
Acyclovir is a poorly permeable, short half-life drug with poor colonic absorption, and current conventional controlled release formulations are unable to decrease the frequency of administration. We designed acyclovir dosage forms to be administered less frequently by being retained in the stomach and releasing drug over an extended duration. We developed a conventional modified-release matrix tablet to sustain the release of acyclovir and surrounded it with a hydrophilic poly(urethane) layer. When hydrated, the porous poly(urethane) swells to a size near or beyond that of the relaxed pylorus diameter and does not affect drug release rate. We demonstrated that the formulation is retained in the stomach for extended durations as it slowly releases drug, allowing for similar area under the curve but delayed tmax relative to a nongastroretentive control tablet. Unlike many other gastroretentive formulations, this dosage form design decouples drug release rate from gastric retention time, allowing them to be modulated independently. It also effectively retains in the stomach regardless of the prandial state, differentiating from other approaches. Our direct observation of excised rat stomachs allowed for a rigorous assessment of the impact of polymer swelling extent and the prandial state on both the dosage form integrity and retention time.
