Ethionamide has a high rate of side effects. [4] Common side effects include nausea, diarrhea, abdominal pain, and loss of appetite. Serious side effects may include liver inflammation and depression. It should not be used in people with significant liver problems. Use in pregnancy is not recommended as safety is unclear. [2]
[7] [8] A drug may be classified as second-line instead of first-line for one of three possible reasons: 1) it may be less effective than the first-line drugs (e.g., p-aminosalicylic acid), 2) it may have toxic side-effects (e.g., cycloserine), or 3) it may be effective, but unavailable in many developing countries (e.g., fluoroquinolones ...
(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
It is a fixed dose combination of ethambutol, isoniazid, pyrazinamide, and rifampicin. [1] It is used either alone or with other antituberculosis medication. [1] It is taken by mouth. [1] Side effects are those of the underlying medications. [1] Pyridoxine may be used to decrease the risk of numbness. [2]
Ethambutol/isoniazid is a fixed-dose combination medication used to treat tuberculosis. [1] It is a fixed dose combination of ethambutol and isoniazid. [1] It is used along with other antituberculosis medication. [1] It is taken by mouth. [1] Side effects are those of the underlying medications. [1]
These gastrointestinal side effects tend to be more common during the first few weeks of treatment or while the patient adjusts to an increased dose. Deposit Photos Severe Side Effects of Ozempic
If these drugs are misused or mismanaged, multidrug-resistant TB (MDR-TB) can develop. MDR-TB takes longer to treat with second-line drugs (i.e., amikacin, kanamycin, or capreomycin), which are more expensive and have more side-effects. XDR-TB can develop when these second-line drugs are also misused or mismanaged and become ineffective.
An enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules (proteins, sugars, etc.) are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently (or not at all) to target receptors.
