Isoniaz > Isoniaz >Ethide are common anti-tuberculosis drugs; Ethide is a structural analogue of isoniazid. As a result, these two drugs have a similar metabolism, toxicity and molecular targets, causing concern for potential cross-reactivity reactions. This concern was addressed in a study with 69 patients on isoniazid treatment who developed adverse skin reactions; serious adverse reactions in 25 patients included drug rash with eosinophilia and systemic symptoms (DRESS), Stevens–Johnson syndrome or toxic epidermal necrolysis. Isoniazid was discontinued in these cases and Ethide treatment started when the initial symptoms had subsided. These 25 patients then underwent rechallenge with isoniazid; a rechallenge reaction occurred in 20 patients. At the same time, 5 patients from the same group reacted to Ethide. It was noted that none of the patients who reacted to isoniazid or Ethide showed cross-reactivity to the other drug .

Adverse Reactions.

Gastrointestinal distress with nausea and vomiting frequently leads to poor compliance and drug discontinuance. Various neurologic disorders have been caused by Ethide , including peripheral neuropathy and psychiatric disturbances. Neurologic side effects have been reported to be alleviated by pyridoxine or nicotinamide. Reversible hepatotoxicity occurs in approximately 5% of Ethide recipients. A hypersensitivity-type rash and poor diabetic control are infrequent complications. Its usage is limited also by a high frequency of severe gastrointestinal intolerance. Hypothyroidism is a recognized complication of Ethide use and is more common when Ethide is combined with PAS. Patients should have periodic screening for hypothyroidism in patients receiving Ethide long term.

What do I need to tell my doctor BEFORE I take Ethide?

You must check to make sure that it is safe for you to take Ethide with all of your drugs and health problems. Do not start, stop, or change the dose of any drug without checking with your doctor. Sites and mechanisms of action

Isoniaz >Ethide , and prothionamide are all prodrugs. Isoniazid is activated by a catalase peroxidase enzyme (KatG). Mutations in KatG account for the majority of isoniazid resistance. The active species of isoniazid appears to have multiple cellular targets. 52 The primary target of isoniazid is believed to be InhA, a NADH-dependent enoyl acyl carrier protein reductase involved in the synthesis of mycolic acid. 53,54 The activated species, presumably an isonicotinic acyl radical, forms an adduct with the NAD radical. The resulting isonicotinic acyl-NADH adduct (INA) binds to InhA, and inhibits the synthesis of mycolic acid, an essential cell wall component of M. tuberculosis ( Figure 6 ). 55
