Valaciclovir, also spelled valacyclovir, is an antiviral medication used to treat outbreaks of herpes simplex or herpes zoster (shingles). [2] It is also used to prevent cytomegalovirus following a kidney transplant in high risk cases. [ 2 ]
Evocative/suppression testing refers to a class of tests performed where one substance is measured both before and after the administration of another substance to determine if the levels are stimulated ("evocative") or suppressed.
There is a consensus among experts that, once initiated, antiretroviral therapy should never be stopped. This is because the selection pressure of incomplete suppression of viral replication in the presence of drug therapy causes the more drug sensitive strains to be selectively inhibited. This allows the drug resistant strains to become dominant.
During a randomized, double-blind trial conducted between 1992 and 1996, hydrocortisone treatment (at a higher dose of 20–30 mg) was associated with some statistical improvement in symptoms of ME/CFS. However, the authors concluded that the degree of adrenal suppression precludes its practical use for ME/CFS. [54]
Fludrocortisone is also a confirmation test for diagnosing Conn's syndrome (aldosterone-producing adrenal adenoma), the fludrocortisone suppression test. Loading the patient with fludrocortisone would suppress serum aldosterone level in a normal patient, whereas the level would remain elevated in a Conn's patient.
Brivudine is used for the treatment of herpes zoster in adult patients. It is taken orally once daily, in contrast to aciclovir, valaciclovir and other antivirals. [1] A study has found that it is more effective than aciclovir, but this has been disputed because of a possible conflict of interest on part of the study authors.
The maximum dose is used, rather than a lower dose, to reduce the number of test subjects (and, among other things, the cost of testing), to detect an effect that might occur only rarely. This type of analysis is also used in establishing chemical residue tolerances in foods. Maximum tolerated dose studies are also done in clinical trials.
The captopril suppression test (CST) is a non-invasive medical test that measures plasma levels of aldosterone. [1] Aldosterone production is suppressed by captopril through the renin–angiotensin–aldosterone system. CST results are used to assist in the diagnososis of primary aldosteronism (Conn syndrome).
