There are several causes of toxic optic neuropathy. [1] Among these are: ingestion of methanol (wood alcohol), ethylene glycol (automotive antifreeze), disulfiram (used to treat chronic alcoholism), halogenated hydroquinolones (amebicidal medications), ethambutol and isoniazid (tuberculosis treatment), and antibiotics such as linezolid and chloramphenicol as well as chloroquine and the related ...

(S,S)-(+)-Ethambutol is powerful and selective antitubercular drug.It is a typical example of an old drug that was introduced for clinical use in its unichiral form. . Ethambutol contains two constitutionally symmetrical chiral centers in its structure and exists in three stereoisomeric forms, the enantiomeric pair (+)-(S,S)- and (−)-(R,R)-ethambutol, along with the achiral stereoisomer called m
Contraindications and adverse side-effects are always a factor, as well. [ 14 ] A corticosteroid implant surgically placed within the eye can be used for patients who are not able to achieve remission on or tolerate immunomodulatory therapy, or in cases where this option presents less of a burden on life than long-term medical therapy.
The optic nerve contains axons of nerve cells that emerge from the retina, leave the eye at the optic disc, and go to the visual cortex where input from the eye is processed into vision. There are 1.2 million optic nerve fibers that derive from the retinal ganglion cells of the inner retina. [2] Damage to the optic nerve can have different causes:
These signs and symptoms are not side effects of the drugs taken which occur during short term use. DIL occurs over long-term and chronic use of the medications listed below. While these symptoms are similar to those of systemic lupus erythematosus , they are generally not as severe unless they are ignored which leads to more harsh symptoms ...
The drug was withdrawn from world market when it became evident that the use in pregnancy causes phocomelia (clinical conditions where babies are born with deformed hand and limbs). Later in late 1970s studies indicated that the (R)- enantiomer is an effective sedative , the (S)-enantiomer harbors teratogenic effect and causes fetal abnormalities.
Cefuroxime is generally well tolerated, and its side effects are usually transient. If ingested after food, this antibiotic is both better absorbed and less likely to cause its most common side effects of diarrhea, nausea, vomiting, headaches/migraines, dizziness, and abdominal pain compared to most antibiotics in its class.
