Abstract:
In order to develop a kind of APAP double-release pellet capsules, which was prepared with the manual filling method, the immediate and sustained release pellets of a certain proportion were prepared by the fluidized bed coating and the extrusion spheroidization process, respectively. It was founded that both the prepared immediate-release pellets and sustained-release pellets had smooth and round surfaces. The particle size distribution ranged evenly from 16 to 35 mesh. Response surface plots showed that the optimal preparation prescription for immediate-release pellets were that ethanol conc

Abstract:
Multi-unit pellet system (MUPS) tablets were fabricated by compacting drug-loaded pellets of either crospovidone or microcrystalline cellulose core. These pellets were produced by extrusion-spheronization and coated with ethylcellulose (EC) for a sustained drug release function. Coat damage due to the MUPS tableting process could undermine the sustained release function of the EC-coated pellets. Deformability of the pellet core is a factor that can impact the extent of pellet coat damage. Thus, this study was designed to evaluate the relative performance of drug-loaded pellets prepared with ei

Abstract:
The compaction of multi-unit pellet system (MUPS) into tablets is a potential alternative for sustained release drugs. Tableting tools (punch and die) affect the compaction process and quality of MUPS tablets. The punch design intends to preserve the desired drug release of compacted pellets. This study aims to investigate the effect of two punch shapes, the flat face radius edge (FFRE) and concave-faced punch (concave), each at two different cup depths, on the physical properties and release profile of metformin HCl MUPS tablets. Drug release parameters, t50 values, showed that the metformin

Abstract:
Tetrodotoxin (TTX) was identified as a latent neurotoxin that has a significant analgesia effect. It was rapidly absorbed and excreted in rat after intramuscular (i.m.) injection. To maintain the effect, frequent injections were required. The enteric sustained-release TTX pellets with sucrose pellets as a drug carrier was prepared by fluidized bed spray irrigation, coated in sequence with Eudragit NE30D as a sustained-release layer, hydroxypropyl methylcellulose (HPMC) as a barrier layer and Eudragit L30D-55 as an enteric coating.

Background: Blood cancer is a significant contributor to mortality rates worldwide, and its prevalence is projected to rise on a global scale. This trend places considerable strain on healthcare systems and necessitates the expedited development of innovative treatments by pharmaceutical firms to remain competitive.

Abstract:
Desmopressin acetate (DDAVP) is an oligopeptide used to treat primary nocturnal enuresis, for example. The low oral bioavailability of DDAVP has expedited the move to other modes of administration such as nasal and oromucosal, with nasal administration resulting in large variations, raising the likelihood of unpleasant side effects. Hyponatremia is common in clinical practice and is mainly caused by renal water retention. Many drugs are thought to be among the different causes of hyponatremia because they either promote the production of arginine vasopressin (AVP) or increase its effect in the

Abstract:
Aceclofenac (AC) is a nonsteroidal anti-inflammatory drug used in the treatment of chronic pain in conditions such as rheumatoid arthritis, with frequent administration during the day. The formulation of sustained release matrix pellets can provide a promising alternative dosage form that controls the release of the drug, with less blood fluctuation and side effects—especially those related to the gastric system. The extrusion/spheronization technique was used to formulate AC matrix pellets. The response surface methodology (version 17.2.02.; Statgraphics Centurion) was used to study the impac
