Significance of Polymer
Polymer refers to large molecules that play critical roles in various drug formulations. These macromolecules are essential as release rate retardants in matrix tablets, influencing the drug release profile. They serve as foundational materials in 3D printing for solid dosage forms and are integral to mouth dissolving strips and microsponges, impacting disintegration and drug release. Additionally, polymers can be studied through IR spectroscopy, offering insights into their structural properties, which are vital for ensuring stability and efficacy in pharmaceutical applications.

Hindu concept of 'Polymer'
In Hinduism, "Polymer" seems to relate to targeted drug delivery in modern herbal formulations. Passive targeting exploits leaky tumor vasculature, while active targeting uses ligands for enhanced delivery.
From: Journal of Ayurvedic and Herbal Medicine
(1) The passive targeting is suitable for tumour due to presence of leaky vasculature in tumours while active targeting can be exploited for modern herbal formulation as it involves attaching ligands to the.[1]
The concept of Polymer in scientific sources
Polymer is a versatile substance characterized by stability and reusability, integral in experimental studies. It encompasses large molecules like Pluronic F-68, affecting microsphere stability and serving as release rate retardants in drug formulations.
From: Asian Journal of Pharmaceutics
(1) A substance present during the crystallization process to slow the growth of nuclei and imparts smoothness to the surface as well as may increase solubility.[2] (2) Large molecules used to increase viscosity.[3] (3) They are of both natural and synthetic origin and are constantly expanding, but only a few of them are used in pharmaceutical production and medical practice.[4] (4) These are materials whose concentration affects drug release, and one example is polyvinyl alcohol which is a water-soluble polymer with film forming property.[5] (5) A material used to make the microsphere, along with waxes and many protective materials.[6]
From: International Journal of Pharmacology
(1) A substance used in the composition of nanocomposites, where nanoparticles spread over its matrix.[7] (2) Substances used in mucoadhesive buccal drug delivery systems.[8] (3) Polymers such as chitosan, carbopol, and poloxamer are used in formulating tramadol hydrochloride for modified-release studies, with increased polymer concentration extending drug release time.[9]
From: The Malaysian Journal of Medical Sciences
(1) This is a large molecule, and microplastics are plastic particles of different shape, size and polymer composition.[10]
From: Sustainability Journal (MDPI)
(1) Polymers, such as Polycarbonates, Polyols, and Polyurethanes, are examples of products resulting from organic synthesis pathways involving carbon dioxide utilization technologies mentioned in the comparative table.[11] (2) Polymers are one category of nonmetallic components and parts focused on in this research, representing materials whose recycling potential needs careful assessment because their recycling technology might not be as mature as that for metals.[12] (3) A category of synthetic materials that form the basis of microplastics, with different types having varying distributions and detection capabilities by analytical methods.[13] (4) This is a type of material discussed in the context of waste management and sustainable production and consumption practices.[14] (5) It is described as large. The narrow line width of singlets suggests the presence of a small molecule, like a monomer, rather than something large.[15]
From: International Journal of Environmental Research and Public Health (MDPI)
(1) The polymer, particularly polyvinyl chloride, is the material in which the diffusion behavior of volatile organic compounds is studied using molecular dynamics simulation.[16] (2) Based on the text, polymers such as polyethylene (PE), polypropylene (PP), polystyrene (PS), ethylene-vinyl acetate (EVA), PET, PES, and SAN are found in outdoor areas.[17] (3) Polymers are a carbon source that biofilms exhibit a preference for, and their metabolic capacity is significantly inhibited by PS-COOH NPs, but not altered by non-functionalized PS NPs.[18]
From: International Journal of Pharmacology
(1) A polymer is used in the preparation of nano-particles, with micro/nano-structures formed after solvent diffusion/evaporation.[19] (2) These are large molecules composed of repeating structural units, which can be involved in food contact materials and migration studies.[20] (3) 5-Hydroxymethylfurfural (HMF) serves as an intermediate for the synthesis of these and other organic derivatives.[21]
