Three-dimensional (3D) printing is quickly being adopted in pharmaceutics due to the many advantages it offers, including treatment, adaptability, reduction waste and accelerated development of new formulations. In this study, micro-extrusion was implemented for production modified-release hydrocortisone (HCT) mini-tablets paediatric patients. For developed formulations, Gelucire® 44/14 Precirol® ATO 5 were used as main inks at three different ratios: 70%/30%, 60%/40% 50%/50%, respectively....

Biodegradable polyesters have been researched intensively over the last two decades because of their biodegradability and superb physical properties. However, use linear biodegradable polyesters, for preparation drug delivery systems (DDS), is hampered by several limitations. In view this, scientific attention has shifted to employment branched-chain (co-)polymers. this context, we present herein development new melatonin (MLT) tablet formulations, using novel branched polylactide...

Obesity is a complex condition characterized by excessive fat accumulation, leading to significant health risks, including cardiovascular diseases, diabetes, and certain cancers. Its multifactorial etiology encompasses genetic predispositions, behavioral factors, like poor eating habits sedentary lifestyles, hormonal imbalances involving leptin insulin resistance. In addition lifestyle interventions, such as balanced diets regular physical activity, pharmacological therapies play pivotal...
