Steroid medications injected into the joints

To limit side effects, oral, inhaled or topical ophthalmological steroids are often prescribed for a very short period of time. However, for many serious conditions, they must be used for longer periods of time. Chronic use of steroids can cause many well-known side effects, including weakened bones, fluid retention, high blood pressure, mood swings and confusion. Less well known is that they can also cause eye problems such as cataracts and glaucoma, notes David F. Chang, MD, a clinical professor of ophthalmology at the University of California, San Francisco and coauthor of Cataracts: A Patient’s Guide to Treatment . The good news is that cataracts are very treatable, as is glaucoma when detected early. Before prescribing steroids, Dr. Chang points out that doctors always try to make sure that the benefits of treatment outweigh the risks and disadvantages, and generally will limit their use to as short a time as possible.

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 [38] 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. [39] [ 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 . [2] : 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. [39]

Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. [45]
