A review. A Review. Sustained release matrix tablet is formulated mainly by wet granulation or direct compression method or by dispersion of solid particle within solid particle within a porous matrix formed by using different polymers like Polymethyl methacrylate (PMMA), Polyglycolic acid, HPMC etc. The matrix controls the release rate of drug. retardants like HPMC can aid in sustained release and thus they form core excipient of the formulation. The method involves the direct compression of blend of drug, retardant material and additives to formulate a tablet in which the drug is embedded in a matrix core of the retardant, alternatively granulation can be carried out prior to compression. The matrixes used may be of hydrophilic, hydrophobic, mineral, or biodegradable types. The drug release rate can be studied by in-ugs that have been formulated as sustained release matrix tablets are Ambroxol HCl, Nateglinide etc. Thus, sustained release matrix tablets can assure better patient compliance through reduction in total dose and dosage regimen, which can be of great help to treat chronic diseases.

The article conveys some information:

The purpose of the present work was to mask the taste of Ambroxol hydrochloride and to formulate its patient-friendly dosage form. Complexation technique using KYRON -T-114 an ion-exchange resin was used to mask the bitter taste and the drug loading onto the ion-exchange resin was optimized for ratio of drug to resin, effect of pH and effect on soaking time. The resinate was evaluated for taste masking and characterized by FT-IR and DSC. Then the taste-masked drug was formulated into a fast dissolving tablet (FDT). The developed tablets were evaluated for hardness, friability, drug content, weight variation, content uniformity, friability, water absorption ratio, in-vitro disintegration time and in-vitro drug release studies. IR and DSC spectra revealed that there were no possible interactions between the drug and polymer. Maximum loading was obtained at drug- resin ratio 1:2, pH 7, and soaking time 30 min. A successful taste masking of resinate was confirmed by time intensity method. The values of pre-compression parameters evaluated and were within prescribed limits and indicated good free flowing properties. The data obtained of post-compression parameters found superior over conventional formulation. The F3 batch with disintegration time 30.4±0.64 s and dissolution 98.4±2.69 was selected as optimized formulation, This was compared with conventional marketed formulation and was found superior. The obtained results revealed that Ambroxol hydrochloride has been successfully taste masked and formulated into an FDT as a suitable alternative to the conventional tablets.trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Reference of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride) was used in this study.

These research results belong to Gangireddy, Ramana; Kolagani, Apoorva; Priyanka, D. Kameswari; Gayatri, P.. Recommanded Product: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride The article mentions the following:

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.

Lee, Sie Huey; Heng, Desmond; Teo, Jeanette W. P.; Toh, Frederick K. Y.; Tan, Reginald B. H. published their research in International Journal of Pharmaceutics (Amsterdam, Netherlands) on December 15 ,2019. The article was titled 《Inhaled mucoactive particles with tailored architecture for enhanced aerodynamicity, stability and efficacy》.Recommanded Product: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride The article contains the following contents:

In respiratory and genetic disorders such as asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis and cystic fibrosis (CF), the lungs produce excess mucus, resulting in a thickened mass, which clogs up the airways and reduces airflow. Consequently, breathing becomes more difficult. Medications that break down the structure of mucus will be especially useful in managing the early symptoms of these diseases and preventing their progression into the more severe forms. This work therefore seeks to develop an inhaled mucoactive dry powder formulation that is efficacious on multiple fronts. As an innovative step, sodium chloride was used to tailor the surface architecture of ambroxol hydrochloride particles, such that the resulting angular features on the surfaces contributed to the creation of corrugated particles with enhanced aerodynamicity. The optimized spray-dried powder particles were of respirable-size (d50 of 2.85 ± 0.15 μm) and moderately corrugated. When the crystalline powder was dispersed via an Aerolizer inhaler at 60 L/min, it gave a fine particle fraction (FPF) of ∼31%, which was a ten-fold improvement over the unmodified species (i.e. ambroxol hydrochloride alone). Tests on artificial sputum medium (ASM) showed that the optimized formulation was potentially useful in liquefying the mucus, which favorably pointed towards the effectiveness of the formulation. In addition, the formulation was also stable to moisture ingress (up to ∼60% RH) and had good flowability. Hence, the advent of angular adjuvant sodium chloride particles in a mucoactive formulation conferred a three-fold benefit to the product: (1) Improved aerodynamicity and flowability, (2) Enhanced moisture stability and (3) Synergistic mucolytic properties. The experimental part of the paper was very detailed, including the reaction process of trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4Recommanded Product: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride)

Ochowiak, M.; Kasperkowiak, A.; Doligalski, M.; Sosnowski, T. R.; Matuszak, M.; Wlodarczak, S.; Markowska, M.; Krupinska, A.; Jablczynska, K. published their research in International Journal of Pharmaceutics (Amsterdam, Netherlands) on August 15 ,2019. The article was titled 《The thermostated medical jet nebulizer: Aerosol characteristics》.SDS of cas: 23828-92-4 The article contains the following contents:

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 After reading the article, we found that the author used trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride(cas: 23828-92-4SDS of cas: 23828-92-4)
