Introduction: Transdermal patches offer a unique advantage by providing extended therapeutic benefits while maintaining stable plasma drug concentration. The efficacy and safety of patches depend significantly on their ability to adhere to the skin, a feature influenced by various external and internal factors.
Areas Covered: The review primarily focuses on the fundamental aspects of adhesion in transdermal patches, including basic information about the skin, the underlying principles of adhesion, drug delivery, and adhesion characteristics of pressure sensitive adhesives (PSAs), adhesion issues, impact factors, strategies to improve patch adhesion, and relevant molecular mechanisms.

Background And Objective: There is a significant medical need for improved long-acting local anesthetics to decrease postsurgical pain and reduce postoperative opioid use. While ropivacaine is considered a safer local anesthetic than bupivacaine, no long-acting ropivacaine formulation is currently marketed. Available formulations of bupivacaine show inconsistent pharmacokinetics (PK) among different surgical models, and inconsistency in PK may lead to a reluctance to use the medication owing to fear of local anesthetic systemic toxicity (LAST) or unreliable efficacy.

Background And Objective: A gonadotropin-releasing hormone (GnRH) agonist such as leuprolide is widely used to achieve sustained suppression of testosterone levels, which play a critical role in the treatment of prostate cancer. Recent advances in drug delivery systems have led to the development of long-acting depot formulations, such as the 6-month intramuscular (IM) leuprolide formulation, which aim to simplify dosing and improve convenience for both patients and healthcare providers. Exploring extended dosing intervals for such formulations represents a promising approach to further optimize treatment regimens, potentially balancing efficacy with patient-centered care.

Hepatocellular carcinoma is one of the leading causes of cancer deaths globally and a key hindrance to extending life expectancy. Celastrol (CEL) demonstrates excellent antitumor activity, but faces challenges like low solubility and a narrow therapeutic window, limiting its clinical application. To address these limitations, drug combinations and nano-delivery systems have emerged as effective solutions.

This study investigates the use of nano-sized oxygen bubbles (NOBs) to enhance BTEX (benzene, toluene, ethylbenzene, xylene) biodegradation in groundwater. Optimized NOBs, averaging 155 nm and at a concentration of 6.59 × 10⁸ bubbles/mL, were found to provide sustained oxygen release with a half-life of approximately 50 days.
