Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small. [ 2 ]
The term also has two other, conflicting meanings. In titration, the titer is the ratio of actual to nominal concentration of a titrant, e.g. a titer of 0.5 would require 1/0.5 = 2 times more titrant than nominal. This is to compensate for possible degradation of the titrant solution.
Red burning skin syndrome from topical steroids. Typical pattern on lower arms and hands. Before discontinuation, steroid dermatitis is characterised by spreading dermatitis and worsening skin inflammation, which requires a stronger topical steroid to get the same result as the first prescription.
A titration curve is a curve in graph the x-coordinate of which represents the volume of titrant added since the beginning of the titration, and the y-coordinate of which represents the concentration of the analyte at the corresponding stage of the titration (in an acid–base titration, the y-coordinate usually represents the pH of the solution).
Along with sharing tapering tips, members of the groups discuss the risks of prescription cascade, where withdrawal symptoms or the side effects of a psychotropic medication result in further medication, and the risk of neurobiological "kindling" effects where repeated unsuccessful withdrawal attempts yield progressively poor results upon drug ...
Titration of a standard solution using methyl orange indicator. Titrate is in Erlenmeyer flask, titrant is in burette. acid + base → salt + water. For example: HCl + NaOH → NaCl + H 2 O. Acidimetry is the specialized analytical use of acid-base titration to determine the concentration of a basic (alkaline) substance using standard acid.
For a strong acid-strong base titration monitored by pH, we have at any i'th point in the titration = [+] [] where K w is the water autoprotolysis constant.. If titrating an acid of initial volume and concentration [+] with base of concentration [], then at any i'th point in the titration with titrant volume ,
While short-term use in the later part of pregnancy is safe, long-term use or use in early pregnancy is occasionally associated with harm to the baby. [1] It is a glucocorticoid made from hydrocortisone . [10] Prednisolone was discovered and approved for medical use in 1955. [10]
