Carboxylic acid, any of a class of organic compounds in which a carbon atom is bonded to an oxygen atom by a double bond and to a hydroxyl group by a single bond. They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than mineral acids such as hydrochloric acid.
In general, longer PEG chains lead to longer circulation times and properties of Improved cover-up In a systematic study of micelles PEG-b-poly (acid lactic-co-glycolic) (PLGA) with molecular weights of PEG in the range of 5,000 to 20,000 Da, Langers and collaborators discovered that coated micelles with PEG chains of 20,000 Da were the least.
The disclosure provides the use of particular substituted heterocycle fused gamma-carboline compounds as pharmaceuticals for the treatment of residual symptoms of psychosis or schizophrenia. The disclosure also provides novel long acting injectable formulations of particular substituted heterocycle fused gamma-carboline compounds and use of such long acting injectable formulations for the.
Poly ( lactic acid ) ( PLA ), poly ( glycolic acid ) ( PGA ) and co-polymers of PLA and PGA ( PLGA ) are normally used in tissue technology surveies as they have Food and Drug Administration ( FDA ) blessing for usage within the human organic structure.
Diethanolamine, often abbreviated as DEA, is an organic chemical compound which is both a secondary amine and a dialcohol. A dialcohol has two hydroxyl groups in its molecule. Like other amines, diethanolamine acts as a weak base.
Several matrices and delivery systems have been used and evaluated for their efficacy and biocompatibility as carrier for growth factors. Two common types of polymeric materials used in growth factor delivery strategies are natural collagen-derived materials and synthetic polymers of lactic and glycolic acid (i.e., Poly (lactide-co-glycolide)).
