Gastro retentive drug delivery is a special approach which remains in the gastric region for a prolonged period to increase gastric residence time and also have the advantage of site-specific drug delivery especially in the upper gastrointestinal tract (GIT) for local or systemic effects. Ambroxol hydrochloride is a systemically active mucolytic agent with a half-life of 3-4 h. It acts by breakdown of acid muco polysaccharide fibers which make the sputum thinner and less viscous as long as treatment is maintained and therefore more easily sputum was removed by coughing. The main aim of the present work is to develop the oral controlled release floating matrix tablets of Ambroxol hydrochloride by direct compression method, using various hydrophilic polymers such as HPMCK100M, Carbopol971P, Polyethylene oxide. FT-IR studies revealed that there was no incompatibility between the drug and polymers used. All the formulations remained buoyant without any disintegration. The formulations F4, F9, F15 have shown the extended drug release close to that of marketed formulation for a period of 12 h. To ascertain the mechanism of drug release in-vitro data was fitted into various release kinetic models like zero order, first order, Higuchi and Peppas. The values indicated the non-fickian diffusion with slow erosion of polymer matrix followed by drug diffusion and resulted in linear drug release profile over a prolonged period of time.

Malviya, Yogendra published the artcileFormulation development and evaluation of gastroretentive floating tablets of ambroxol hydrochloride, Formula: C13H19Br2ClN2O, the publication is Journal of Drug Delivery and Therapeutics (2019), 9(4Suppl.), 1016-1021, database is CAplus.

The present study is focused on the development of gastroretentive floating drug delivery system of ambroxol hydrochloride, which acts as a mucolytic agent that is reported to be useful in gastric neoplasms which are designed to increase the gastric residence time, thus prolonging the drug release in the stomach. Gastro retentive floating tablets of ambroxol hydrochloride were prepared by direct compression method using altered concentrations of HPMC K4, HPMC K15 and PVP K30 as polymers. Sodium bicarbonate and citric acid was used as gas releasing agent. The prepared tablets of ambroxol hydrochloride were evaluated for hardness, thickness, friability, weight variation, drug content uniformity, buoyancy lag time, total floating time, in-vitro dissolution study, etc. All the compositions were resulted in adequate Pharmacopoeial limits. Compatibility studies was execution during FTIR shown that there was absence of probable chem. interaction between pure drug and excipients. The varying concentration of gas generating agent and polymers was found to affect on in-vitro drug release and floating lag time. In vitro drug release of floating gastro retentive tablet of ambroxol hydrochloride shown that the formulation F6 was found to be the best formulation as it releases 99.87% in a controlled manner for an extended period of time (up to 12 h). The release data was fitted to various math. models such as Higuchi, Korsmeyer-Peppas, First order and Zero order to evaluate the kinetics and mechanism of the drug release. The optimized formulation (F6) showed no significant change in phys. parameters such as, hardness, friability, weight variation and %drug content for accelerated stability condition at 40±2°C temperature and 75±5% relative humidity for a period 3 mo. Prepared floating tablets of ambroxol hydrochloride may prove to be a potential candidate for safe and effective controlled drug delivery over an extended period of time for gastro retentive drug delivery system.

Ochowiak, M. published the artcileThe thermostated medical jet nebulizer: Aerosol characteristics, Quality Control of 23828-92-4, the publication is International Journal of Pharmaceutics (Amsterdam, Netherlands) (2019), 118475, database is CAplus and MEDLINE.

The sudden expansion of gas at the outlet of the jet (pneumatic) nebulizer significantly reduces the temperature of the solution, which may provoke bronchospasm, therefore it is recommended to use modern pneumatic inhalers equipped with a thermostat or a universal thermal attachment that allow to obtain a higher temperature aerosol, i.e. thermo-aerosol. The research was carried out for model Newtonian fluids. The droplet diameters of the aerosol spray were investigated using a Spraytec aerosol particle size measurement system. Anal. of the obtained results showed that the increase in solution viscosity caused a decrease in mean droplet diameters and prolonged nebulization time. The anal. of exptl. data made it possible to propose a correlation equation describing the mean diameter of the droplets depending on the properties of the liquid and the flow conditions in the thermostated medical nebulizer. The obtained data contributes to a better understanding of the complex liquid atomization process and can be helpful in the design of medical nebulizers and pharmaceutical preparations

Zhou, Xufeng published the artcileEfficacy and safety of ambroxol hydrochloride in the treatment of secretory otitis media: a systematic review and meta-analysis, COA of Formula: C13H19Br2ClN2O, the publication is Annals of Translational Medicine (2022), 10(3), 142, database is CAplus and MEDLINE.

Secretory otitis media is a very common nonsuppurative inflammatory disease in otorhinolaryngol. Ambroxol hydrochloride helps to improve ciliary movement in the ear canal and promote the dissolution and discharge of secretions. However, its effect still lacks systematic evaluation. We conducted a meta-anal. of clin. studies to systematically evaluate the application effect of ambroxol hydrochloride. A computer-based search of the Chinese Biomedical Database (CBM), China National Knowledge Infrastructure (CNKI), PubMed, and Web of Science databases was conducted using the keywords “Ambroxol hydrochloride” & “secretory otitis media”. Randomized controlled trials published after 2015 were selected and then screened and analyzed using RevMan 5.4 software. Ten studies involving a total of 998 patients were included. Meta-anal. showed that adding ambroxol hydrochloride to the original glucocorticoid treatment improved therapeutic efficacy [odds ratio (OR) = 4.95, 95% confidence interval (CI): 3.27, 7.50, P<0.00001], reduced tympanic pressure after treatment [mean difference (MD) = -19.04, 95% CI: -22.72, -15.36, P<0.00001], and increased the pure tone threshold (MD =6.37, 95% CI: 5.36, 7.37, P<0.00001), without increasing adverse reactions (OR = 0.51, 95% CI: 0.14, 1.85, P=0.30). On the basis of the original treatment of secretory otitis media, adding ambroxol hydrochloride treatment improved the therapeutic effect, reduced tympanic pressure after treatment, and improved the pure tone threshold (hearing), without increasing adverse reactions.

Wollenburg, Marco published the artcileTrans-Selective and Switchable Arene Hydrogenation of Phenol Derivatives, COA of Formula: C13H19Br2ClN2O, the publication is ACS Catalysis (2020), 10(19), 11365-11370, database is CAplus and MEDLINE.

A trans-selective arene hydrogenation of abundant phenol derivatives catalyzed by a com. available heterogeneous palladium catalyst was reported. The described method tolerates a variety of functional groups and provides access to a broad scope of trans-configurated cyclohexanols as potential building blocks for life sciences and beyond in a one-step procedure. The transformation is strategically important because arene hydrogenation preferentially delivers the opposite cis-isomers. The diastereoselectivity of the phenol hydrogenation can be switched to the cis-isomers by employing rhodium-based catalysts. Moreover, a protocol for the chemoselective hydrogenation of phenols to cyclohexanones was developed.
