Famotidine suffers from low oral bioavailability due to poor aqueous solubility, short half-life, and limited gastric retention. This study aimed to develop gastro-retentive floating tablets of famotidine using hot-melt extrusion (HME) and fused deposition modeling (FDM) 3D printing approach to enhance its solubility, prolong gastric residence, and achieve extended drug release. Famotidine was incorporated into various polymer...

Purpose Granulation is one of the important unit operations in the manufacturing of solid dosage forms like tablets and capsules that regulate the quality of end products. It is a process of particle enlargement by agglomeration technique, which improves flow properties, compressibility, reduction of dust formation, drug content uniformity, dissolution rates, and overall product stability. Traditionally, it has been a batch pr...

Purpose This study aimed to develop immediate-release Quetiapine Fumarate (QTF) tablets using twin-screw melt granulation (TSMG), a solvent-free and efficient granulation method, and compare their dissolution profiles with the marketed product. Methods QTF tablets were formulated using TSMG with varying concentrations of Ludiflash ® as a diluent and HPMC as a binder. Granules were prepared using a twin-screw extruder at 150 °C...

Purpose The purpose of this research was to develop and characterize dual-drug Isoniazid-Pyridoxine gummies using Semisolid Extrusion (SSE) 3D printing technology, aimed at personalized dosing for a broad patient demographic, from pediatric to geriatric. This study leverages SSE 3D printing, an innovative approach in personalized medicine, to enable precise dose customization and improve patient adherence. By formulating dual...

The hot-melt extrusion process is currently considered a prominent manufacturing technique in the pharmaceutical industry. The present study is intended to develop amlodipine besylate (AMB)-loaded subcutaneous implants to reduce the frequency of administration, thus improving patient compliance during hypertension management. AMB subcutaneous implants were prepared using continuous hot-melt extrusion technology using poly(capr...

Purpose The current study assessed the potential of a pneumatic 3D printer in developing a taste-masked tablet in a single step. Metronidazole (MTZ) was chosen as the model drug, and Eudragit® E PO was used as a taste-masking polymer to produce taste-masked tablets. Methods The study focused on optimizing processing parameters, such as the nozzle's printing speed, the printhead's heating temperature, and the pressure. Oval-sha...

Purpose The application of 3D printing technology in drug delivery is often limited by the challenges of achieving precise control over drug release profiles. The goal of this study was to apply surface equations to construct 3D printed tablet models, adjust the functional parameters to obtain multiple tablet models and to correlate the model parameters with the in vitro drug release behavior. Methods This study reports the de...

This review investigates the progression and effectiveness of colon-targeted drug delivery systems, offering a comprehensive understanding of the colon's anatomy and physiological environment. Recognizing the distinctive features of the colon is crucial for successfully formulating oral dosage forms that precisely target specific areas in the gastrointestinal tract (GIT) while minimizing side effects through mitigating off-tar...

Hot-melt extrusion (HME) is a globally recognized, robust, effective technology that enhances the bioavailability of poorly soluble active pharmaceutical ingredients and offers an efficient continuous manufacturing process. The twin-screw extruder (TSE) offers an extremely resourceful customizable mixer that is used for continuous compounding and granulation by using different combinations of conveying elements, kneading eleme...
