Controlled release technology is designed to release drugs at a predictable and carefully programmed rate, ensuring optimal serum-drug concentrations. This dosage form improves the safety, efficacy, reliability, and convenience of drug therapy, providing more consistent treatment outcomes and enhancing patient adherence.
At LANDU, we offer a variety of pharmaceutical additives, including cellulose ethers, dextrin, pregelatinized starch, and enteric coating powder. We collaborate closely with customers to provide innovative solutions. Contact us for more product information.
01.
Hydroxypropyl Methyl Cellulose (HPMC) is a versatile pharmaceutical excipient. It functions as a thickener, dispersant, emulsifier, and film-forming agent. When used as a film coating and binder, it boosts the dissolution rate of drugs. It also acts as a suspension aid and is utilized in ophthalmic preparations.
HPMC manages drug release and distribution, enhancing therapeutic outcomes and patient satisfaction.
02.
Ethyl Cellulose, which doesn’t dissolve in water but does in organic solvents, is used to strengthen tablets and minimize friability. It also improves the appearance of tablets and masks their taste.
Additionally, it protects water-sensitive medications and aids in creating sustained-release formulations.
03.
Microcrystalline cellulose (MCC) is a tasteless, insoluble cellulose used for its high drug loading, adhesion, and tablet compression properties. It serves as a filler, binder, and disintegrant in pharmaceuticals due to its good fluidity.
LANDU MCC is used as a pharmaceutical excipient, non-caloric food additive, and chromatography filler. It also functions as a carrier for dyes, reinforcing filler, and emulsifier in various industries.
04.
LANDU HPS product serves as an outstanding thickener and water retention agent, boosting product performance with a small amount. It is stable in both acidic and alkaline environments, has a lower gelatinization temperature than regular starch, and maintains stable viscosity despite temperature fluctuations.
Moreover, etherified starch provides enhanced freeze-thaw stability and clarity, making it suitable for diverse applications.
05.
Low-substituted Hydroxypropyl Cellulose (L-HPC) is a non-ionic, white or crystalline powder created by reacting alkali cellulose with propylene oxide. It is insoluble in water and organic solvents like acetone and ethanol, but it can swell rapidly in water. The degree of swelling varies depending on the hydroxypropyl content.
L-HPC is unaffected by the pH levels of gastrointestinal fluids, making it an ideal additive for tablet production. It is specifically designed to enhance the manufacturing process of tablets.
06.
Hydroxypropyl Methylcellulose Phthalate (HPMC-P) is a white or off-white granular solid that is tasteless. It serves as an enteric coating material with excellent resistance to gastric acid and is insoluble at a pH of 5.0-5.5.
Primarily used in tablets and granules, it also finds applications in aquaculture, biotechnology, and various other industries.
07.
Hydroxypropyl Methylcellulose Acetate Succinate (HPMCAS) is a combination of HPMC acetate and succinic acid. It is a tasteless, white to light yellow powder or granule, mainly utilized for enteric coatings.
This enteric coating material forms effective films without requiring a plasticizer. It dissolves efficiently in the upper small intestine (duodenum), thereby improving drug absorption in the small intestine.
08.
Sodium Carboxymethylcellulose is a key cellulose ether created through the chemical alteration of natural fibers. It is a polyanionic substance that dissolves well in both cold and hot water.
This compound has distinctive and beneficial physical and chemical properties, including emulsifying capabilities, stability, decay resistance, and being safe for physiological use. It is extensively used as a derivative of natural macromolecules.
