Article Abstract
Introduction: Drug delivery systems with extended-release profiles are ideal in improving patient compliance with enhanced efficacy. To develop devices capable of a prolonged delivery kinetics, it is crucial to understand the various underlying mechanisms contributing to extended drug release and the impact thereof on modulating the long-term performance of such systems in a practical application environment.
Areas Covered: This review article intends to provide a comprehensive summary of release mechanisms in extended-release drug delivery systems, particularly polymer-based systems; however, other material types will also be mentioned. Selected current research in the delivery of small molecule drugs and macromolecules is highlighted. Emphasis is placed on the combined impact of different release mechanisms and drug properties on the long-term release kinetics and .
Expert Opinion: The development of drug delivery systems over an extended duration is promising but also challenging when considering the numerous interrelated delivery-related parameters. Achieving a well-controlled extended drug release requires advanced techniques to minimize burst release and lag phase, a better understanding of the dynamic interrelationship between drug properties and release profiles over time, and a thorough elucidation of the impact of multiple conditions to methodically evaluate the eventual clinical efficacy.

Background: People living in prison face exceptionally high prevalence rates of tooth decay, periodontal disease, and poor oral health-related quality of life. Despite its importance, various aspects of oral healthcare in prison settings remain understudied. The present study investigates the barriers and facilitators associated with providing and utilizing oral health services in prison settings, drawing on insights from prison health experts, managerial and custodial staff, healthcare providers, and individuals with lived experience of imprisonment.

Purpose: To evaluate the preclinical efficacy and safety of transarterial chemoembolization (TACE) using doxorubicin-loaded biocompatible cellulose nanoparticles in a rabbit VX2 liver tumor model.
Materials And Methods: Following institutional animal care committee approval, 23 rabbits with VX2 liver tumors were randomized into three groups: Group A (n = 9) received doxorubicin-loaded cellulose nanoparticles with ethiodized oil; Group B (n = 9) received doxorubicin with ethiodized oil; and Group C (n = 5) served as untreated controls. Tumor size was monitored via ultrasound for 4 weeks, and serum liver enzymes (aspartate transaminase and alanine transaminase) were measured on days 1, 3, and 7 to assess hepatotoxicity.
A numerical investigation of the kinematic and fluid dynamic behaviour of an intramuscular autoinjector designed for optimising injection efficiency.

The usability and versatility of autoinjectors in managing chronic and autoimmune diseases have made them increasingly attractive in medicine. However, investigations into autoinjector designs require an understanding of the kinematic properties and fluid behaviour during injection. To optimise injection efficiency, this study develops a mathematical and computational fluid dynamics (CFD) model of an IM autoinjector by investigating the effects of viscosity, needle length, needle diameter, and medication volume on the injection process.

Targeted drug delivery significantly enhances therapeutic efficacy across various diseases, particularly in cancer treatments, where conventional approaches such as chemotherapy and radiotherapy often cause severe side effects. In this context, nucleic acid aptamers-short, single-stranded DNA or RNA oligonucleotides capable of binding specific targets with high affinity-have emerged as promising tools for precision drug delivery and therapy. Aptamers can be selected against whole, living cells using SELEX and chemically modified for diverse applications.

Indole-3-carboxaldehyde (I3A), a microbial tryptophan metabolite, exhibits significant immunomodulatory activity at the host-microbial interface. However, its rapid transformation into metabolites like indole-3-carboxylic acid (I3CA) raises questions about their therapeutic potential. This study aimed to evaluate the pharmacological contributions of I3CA through the development of a proper delivery strategy.
