The present study was carried out with an objective of formulation and evaluation of effervescent floating tablets of Tizanidine hydrochloride using combination of polymers. The floating tablets were prepared using HPMC and Tara gum as a combination of polymers. The tablet was prepared by direct compression method. The effect of polymer concentration was evaluated for gastroretention and sustained release action. Effervescence was produced by using sodium bicarbonate and citric acid which helps in reduction in floating lag time. The effect of polymer concentration on drug release and gastroretension has also been investigated. The results of in-vitro dissolution study shows that the drug formulation containing HPMC K15 M and Tara gum gives sustained action till 15 hr. Tara gum act as a sustained release polymer it sustains the dissolution of formulation by modifying the rheology of matrix. it is inert and non-toxic material. The formulation shows zero order kinetics. The matrix of formulation shows non-fickian diffusion. The present study shows that formulation gives sustained release action with muscle relaxant property...

Indian spices and medicinal herbs are well known throughout the world. Both have many different physiological and pharmacological characteristics. The current biomedical research is mostly concentrated on finding chemicals extracted from natural sources that are pharmacologically efficient and have little to no side effects for application in food production and preventative medicine. Pepper (Piper nigrum) is a common spice found in both Eastern and Western cuisine. It helps in digestion and weight loss by encouraging the breakdown of fat cells and has a remarkable antioxidant and antibacterial impact. Numerous independent researchers have conducted experiments that show pepper and its main ingredient, piperine, to have a variety of physiological effects. In-vitro studies have shown that piperine can prevent oxidative damage by suppressing or inhibiting harmful free radicals and oxygen compounds that are reactive. Apart from anti-oxidant property, analgesic, anti-inflammatory, anti-diarrheal, antispasmodic, antidepressant, immunomodulatory, anticonvulsant, anti-thyroid, antibacterial, antifungal, hepato-protective, insecticidal, and larvicidal activities are just a few of the potential pharmacological effects of Piper nigrum L and its active component, “Piperine,”....

The study focuses on creating and evaluating a specialized bilayer tablet for treating hypertension. It begins with in-depth preformulation analyses of key components like Atenolol, Hydrochlorothiazide, and various excipients. Special emphasis is placed on optimizing the powder blend’s flow properties to facilitate tablet compression. A series of tests on resulting tablets (F1 to F8) assess weight variation, thickness, hardness, friability, disintegration time, and drug content, ensuring they meet required specifications with uniform weight and hardness. Dissolution profiles of all formulations are examined, with Formulation 8 (F8) identified as the most suitable for consistent drug release across both layers. The study investigates drug release mechanisms, finding that both layers adhere to the diffusion-controlled release model, particularly the Higuchi model. Stability tests conducted under elevated temperature and humidity (40°C/75% RH) over three months reveal minimal changes in physical attributes, drug content, and drug release profiles, confirming the tablet’s stability. In conclusion, the study successfully develops an optimized Immediate Release Bilayer Tablet containing Atenolol and Hydrochlorothiazide. This tablet offers controlled and uniform...

This systematic review provides a comprehensive overview of recent advancements in liquid crystalline nanoparticles (LCNs) utilized for transdermal drug delivery systems. Recent literature indicates a surge in research emphasizing lipid carriers derived from glyceryl monooleate and monoolein. The inherent nanostructure of LCNs offers superior solubilization capacity for bioactive molecules and controlled release mechanisms. This study underscores the potential of the cubic phase in LCNs as an innovative avenue for sustainable Transdermal Drug Delivery Systems (TDDS). Recent studies highlight the growing interest in cubosomes and hexosomes. Critical analysis necessitates further exploration into the therapeutic efficacy of Alpha lipoic acid cubosomes for anti-wrinkle applications, and the viability of hexagonal phase nano dispersions for in vivo peptide and siRNA delivery. A bibliometric assessment points out China as the leading contributor to LCN-centric publications. To summarize, LCNs are poised as potent TDDS, warranting future exploration in live skin imaging and immunological evaluations in animal model studiesproperties thus increasing residence time of drug with better patient...

Moringa oleifera leaves, have a high antioxidant content, which is beneficial for overcoming free radicals in the body. The leaves contents have the potential to be developed into a functional drink in the form of effervescent granules. The important aspects influencing the acceptability of granule is the type and ratio of the effervescent agent. In this study, citric acid and sodium bicarbonate were used as effervescent agents because they both provide acceptable texture and mouth feel. This study aimed to develop an effervescent granules formulation of Moringa oleifera leaf extract and to optimize the molar ratio of citricacid and sodium bicarbonate as the effervescent agent. Three formulations using different ratios of citric acid and sodium bicarbonate were selected, namely F1, F2 and F3. These formulations were developed using the wet granulation method. The results showed by effervescent granules of the three formulations exhibited good flow ability and good particle size distribution. The organoleptic and sensory evaluation results showed formulation F3 was the most acceptable in terms of colour, taste,...
