Hydrogels can be used as drug delivery vehicles, for transdermal application, ophthalmic drug delivery, [11] cancer treatment [12] or for wound dressing. [ 7 ] [ 13 ] As a type of water based formulation, hydrogels are generally less greasy and are easier to be removed than oil-based formulations like organogels. [ 6 ]
Parenteral drug delivery: Emulsions serve as carriers for intravenous or intramuscular administration of drugs, solubilizing lipophilic ones while protecting from degradation and decreasing injection site irritation. Examples include propofol as a widely used anesthetic and lipid-based solutions used for total parenteral nutrition delivery.
Gold-containing drugs are pharmaceuticals that contain gold. Sometimes these species are referred to as "gold salts". Sometimes these species are referred to as "gold salts". "Chrysotherapy" and "aurotherapy" are the applications of gold compounds to medicine. [ 1 ]
The term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension).
Milk is an emulsified colloid of liquid butterfat globules of 0.1 to 10 micrometer dispersed within a water-based solution.. Interface and colloid science is an interdisciplinary intersection of branches of chemistry, physics, nanoscience and other fields dealing with colloids, heterogeneous systems consisting of a mechanical mixture of particles between 1 nm and 1000 nm dispersed in a ...
Hydroxyethyl starch (HES/HAES), sold under the brand name Voluven among others, is a nonionic starch derivative, used as a volume expander in intravenous therapy.The use of HES on critically ill patients is associated with an increased risk of death and kidney problems.
Each point within the triangle represents a possible composition of a mixture of the three components or pseudo-components, which may consist (ideally, according to the Gibbs' phase rule) of one, two or three phases. These points combine to form regions with boundaries between them, which represent the "phase behavior" of the system at constant ...
Immunoglobulin therapy is the use of a mixture of antibodies (normal human immunoglobulin) to treat several health conditions. [13] [14] These conditions include primary immunodeficiency, immune thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy, Kawasaki disease, certain cases of HIV/AIDS and measles, Guillain–Barré syndrome, and certain other infections when a ...
