Triamcinolone Acetonide Cream is available in % strengths in 15, 30 and 80 g tubes and is applied two to four times a day, depending on the doctor's prescription. After Triamcinolone Acetonide Cream is applied, the affected area should not be covered unless directed by a doctor. Drug interactions may occur with certain cancer chemotherapy agents and other topical medications. Warnings may apply to individuals who have infections, certain eye conditions, circulatory disorders, or immune disorders. Triamcinolone Acetonide Cream is generally avoided during pregnancy and women who are breastfeeding. In cases where the benefits of treatment outweigh the risks, Triamcinolone Acetonide Cream may be used with extreme caution in pregnant or women who are breastfeeding. Caution is advised when using the drug in pediatric patients as they have a greater susceptibility to corticosteroid-induced hypothalamic- pituitary -adrenal (HPA) suppression and Cushing's syndrome.
Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more  or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram.  [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography .  : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity.
