What are polymers in pharmaceutical?
Polymers could play different roles in the design of pharmaceutical dosage forms. They can be used as suspending, emulsifying, binding, and flocculating agents, and as adhesives, packaging, and coating materials. They can also be used to make gels, nanoparticles, microparticles, and various capsules.
What is a benefit of using polymers for drug delivery?
There are several advantages of polymer acting as an inert carrier to which a drug can be conjugated, for example, the polymer improves the pharmacokinetic and pharmacodynamic properties of biopharmaceuticals through various ways, such as, increases the plasma half-life, decreases the immmunogenicity, boost stability …
What are polymers in Ndds?
A polymer ( Greek poly-, “many” + -mer, “part”) is a large molecule, or macromolecule, composed of many repeated subunits. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function.
What is polymer and its use?
Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester. The term polymer is often used to describe plastics, which are synthetic polymers.
Which polymer is mostly used in pharmaceutical formulation?
polymer polysaccharide, gummy exudates are the natural polymers which are used in formulating pharmaceutical products. are chitosan, carrageenan, isapghula, acacia, gelatin, agar, shellac, guar gum.
Why are polymers so important?
Organic polymers play a crucial role in living things, providing basic structural materials and participating in vital life processes. For example, the solid parts of all plants are made up of polymers. Starches, important sources of food energy derived from plants, are natural polymers composed of glucose.
What are the 4 categories of polymers?
Terms. Synthetic polymers are human-made polymers. From the utility point of view, they can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers.
