2-Bromopyridine reacts with butyllithium to give 2-lithiopyridine, [2] which is a versatile reagent. [3] Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using either sodium dithionite or sodium sulfide with sodium hydroxide to introduce the thiol functional group.
Pyrithione is the common name of an organosulfur compound with molecular formula C 5 H 5 NOS, chosen as an abbreviation of pyridinethione, and found in the Persian shallot. [4] It exists as a pair of tautomers, the major form being the thione 1-hydroxy-2(1H)-pyridinethione and the minor form being the thiol 2-mercaptopyridine N-oxide; it crystallises in the thione form.

Common side effects include headache, vomiting, sleepiness, loss of appetite, cough, rash, and joint pain. [1] Serious side effects include allergic reactions. [1] Use during pregnancy appears to be safe for the baby but this use has not been well studied. [2] Mesna is an organosulfur compound. [3] It works by altering the breakdown products of ...
In the U.S., the drug was marketed by Mission Pharmacal at $1.50 per pill, but in 2014 the rights were bought by Retrophin, owned by Martin Shkreli, and the price increased to $30 per pill for a 100 mg capsule.
Bradycardia; Hypertension (high blood pressure); Allergic reactions (e.g. dyspnoea (shortness of breath), bronchospasm, wheezing, angioneurotic oedema) Anaphylaxis; Changes in appetite
The side effects of nicergoline are usually limited to nausea, hot flushes, mild gastric upset, hypotension and dizziness. [6] At high drug dosages, bradycardia, increased appetite, agitation, diarrhea and perspiration were reported. Most of the available literature suggests that the side effects of nicergoline are mild and transient. [2]
After 1 year of treatment there was a 1.4% reduction in the exacerbation rate with erdosteine treatment; this result was mainly driven by the reduction in the rate of mid exacerbations equal to 57.1%. Furthermore, erdosteine treatment was associated with a 24.6% decrease in all exacerbation duration compared to placebo.
Common side effects include high blood pressure, pain at the site of the injection, vomiting, and fever. [3] It is not recommended for people with peanut allergies as it is typically formulated as a suspension in peanut oil. [3] It is unclear if use in pregnancy is safe for the baby. [3] Dimercaprol is a chelator and works by binding with heavy ...
