ethionamide

Ethionamide is an antibiotic medication that is used in combination with other drugs to treat tuberculosis (TB). It effectively kills or inhibits the growth of bacteria, but it is not effective against viral infections such as colds or the flu.

When ethionamide is taken with cycloserine, there have been reports of convulsions, so it is important to be cautious when using both of these drugs in a treatment regimen. Additionally, it is advised to avoid excessive consumption of ethanol as it has been associated with psychotic reactions.

Ethionamide, along with prothionamide and pyrazinamide, is a derivative of nicotinic acid that is closely related to isoniazid. It is believed that ethionamide undergoes changes within cells and functions similarly to isoniazid. Isoniazid works by blocking the production of mycoloic acids, which are crucial for the formation of the bacterial cell wall.

Isoniazid and pyrazinamide are bactericidal against M. tuberculosis, while ethambutol is typically considered bacteriostatic, although it may have bactericidal effects at higher doses.

Symptoms of optic neuropathy/optic neuritis/retrobulbar neuritis include decreased visual acuity, scotoma, and color blindness. Other symptoms may include peripheral neuropathy, hepatotoxicity, numbness and tingling of extremities due to peripheral neuritis, mental confusion, disorientation, possible hallucinations, and psychosis.

Ethambutol, also known by its brand name Myambutol, is a prescription medication prescribed for the treatment of Tuberculosis.

The typical adverse reactions of PAS include ongoing feelings of nausea, vomiting, and diarrhea. If a patient is feeling fatigued, it could potentially be attributed to hypothyroidism, which occurs when the thyroid gland does not produce enough thyroid hormone, and this can be caused by PAS. Additionally, PAS has the potential to induce hepatitis, which is characterized by liver inflammation, often preceded by a rash or fever.

Summary of Risk: This drug has been found to have the potential to cause birth defects in animals when given doses higher than the recommended human dosage.

Ethionamide, prothionamide, and PAS are second-line anti-TB drugs that have been linked to hypothyroidism. The mechanism behind this side effect is the inhibition of thyroid hormone synthesis through iodine organification inhibition.

Ethionamide is a prodrug that requires activation by the mono-oxygenase enzyme ethA in Mycobacterium tuberculosis. Once activated, it binds with NAD+ to form an adduct that inhibits InhA in a similar manner to isoniazid. The drug is believed to disrupt mycolic acid, which is the basis for its mechanism of action.

Ethionamide is a second-line medication used in combination with other drugs to treat drug-resistant tuberculosis. It has been associated with temporary, asymptomatic increases in serum aminotransferase levels and, in rare cases, severe acute liver injury.

DNA gyrase is a well-established target for the development of anti-tubercular drugs. This enzyme relies on ATP for its activity and plays a crucial role in facilitating DNA replication, transcription, and recombination in bacteria.

Delamanid functions by inhibiting the production of mycolic acids, leading to the destabilization of the bacterial cell wall. This medication belongs to the nitroimidazole class.

Isoniazid is effective in killing bacteria from the Mycobacterium genus, including M. tuberculosis, M. bovis, and M. kansasii.

Rifampin, also referred to as rifampicin, demonstrates antibacterial effects against various gram-positive cocci such as Mycobacteria and Clostridium difficile. It also targets specific gram-negative organisms including Neisseria meningitidis, N gonorrhoeae, and Hemophilus influenza.

For the treatment of tuberculosis (TB), Isoniazid is a highly effective drug, while Ethionamide is a second-line drug used for multidrug-resistant (MDR) TB. Although both compounds are pro-drugs that require activation by different enzymes, they have common pathways that can result in cross-resistance.

The potential cause of ethionamide-induced hypothyroidism is the structural similarity of ethionamide compounds to thioamide, such as propylthiouracil (C7H8N2S), which inhibits the synthesis of thyroid hormones.

Certain medications have the potential to cause drug-induced hypothyroidism, which is characterized by low levels of thyroid hormones. Amiodarone, lithium, and certain cancer medications such as tyrosine kinase inhibitors are commonly associated with this condition. To ensure that your thyroid function is not affected, your healthcare provider may conduct blood tests before starting any of these medications.

Taking this medicine may lead to serious side effects, such as liver damage, especially in patients who are 50 years old or older. It is important for you and your doctor to have a discussion about the potential benefits and risks associated with this medication.

Symptoms of potential liver damage include clumsiness or unsteadiness, dark urine, loss of appetite, nausea or vomiting, numbness, tingling, burning, or pain in hands and feet, unusual tiredness or weakness, and yellow eyes or skin.

If you experience any signs of an allergic reaction to Ethambutol (Myambutol), such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat, seek immediate medical assistance. It is important to note that Ethambutol can potentially lead to severe vision problems, including permanent vision loss.

Fortunately, the majority of medications such as glucocorticoids, dopamine agonists, somatostatin analogs, and rexinoids do not result in clinically apparent central hypothyroidism, as they primarily suppress TSH in the thyrotrope or hypothalamus.

The input consists of a list of drugs: Anti-Arrhythmia Agents, Antipsychotic Agents, Protein Kinase Inhibitors, Lithium, Protein-Tyrosine Kinases, and Amiodarone.

Eye problems can occur in individuals with hypothyroidism. These eye issues may also be caused by the medications commonly prescribed for treating an underactive thyroid.

Based on the literature, the development of SLE due to disrupted immune regulation is linked to the inhibitory interaction between isoniazid and complement component C4, potentially leading to impaired immune complex clearance. In this particular case, it is possible that metabolites of isoniazid triggered this reaction.

Ethionamide, prothionamide, and PAS are second-line anti-TB drugs that have been linked to hypothyroidism. The mechanism behind this side effect is the inhibition of thyroid hormone synthesis through iodine organification inhibition.

Ethionamide, also known as 2-(ethyl)isonicotinthioamide (34.1. 18), is a derivative of isonicotinic acid that is synthesized using the following method: Diethyl oxalate is condensed with methylethylketone in the presence of sodium ethoxide to form the ethyl ester of propi-onylpyruvic acid (34.1.

Possible side effects of this medication include nausea, vomiting, diarrhea, abdominal or stomach pain, increased saliva, a strange metallic taste in the mouth, loss of appetite, or sores in the mouth. If any of these side effects persist or worsen, it is important to inform your doctor or pharmacist immediately. Additionally, it is important to note that some individuals may experience more severe side effects while using this medication.

Ethionamide has been found to cause different neurologic disorders, such as peripheral neuropathy and psychiatric disturbances. The use of pyridoxine or nicotinamide has been reported to help alleviate these neurologic side effects. Additionally, around 5% of individuals who receive ethionamide experience reversible hepatotoxicity.

Trecator, also known as ethionamide, is a medication prescribed for the treatment of tuberculosis (TB).

Ethionamide is effective against lepromatous leprosy and is sold as 250 mg tablets, both in generic versions and under the brand name Trecator.

To minimize stomach upset, you can take Ethionamide with or after meals. It is crucial to continue taking this medication for the entire duration of your TB treatment, even if you start feeling better within a few weeks. This will ensure complete clearance of the infection.

The activation of the antituberculosis drug ethionamide is facilitated by a flavoprotein monooxygenase, as reported in a study published in the Journal of Biological Chemistry in April 2002.

Drug Mean daily dosage
Isoniazid 5 mg/kg
Rifampicin 10 mg/kg
Ethambutol 15-25 mg/kg
Pyrazinamide 30-40 mg/kg

If you are diagnosed with an active TB disease, your treatment will likely involve taking a combination of antibacterial medications for a duration of six to 12 months. The standard treatment for active TB involves using isoniazid (INH) along with three other drugs: rifampin, pyrazinamide, and ethambutol.

The drug is widely distributed throughout the body, achieving effective concentrations in various organs and bodily fluids, including the cerebrospinal fluid. The orange-red color of saliva, tears, sweat, urine, and feces is attributed to this extensive distribution, as the drug itself has a red hue.

It is believed that ethionamide undergoes changes within cells and functions similarly to isoniazid. Isoniazid works by blocking the production of mycoloic acids, which are crucial for the formation of the bacterial cell wall.

You may experience headache, drowsiness, dizziness, or shaking (tremor) while taking this medication. If any of these symptoms persist or worsen, it is important to notify your doctor or pharmacist immediately. It is important to remember that this medication has been prescribed to you because your doctor has determined that the benefits outweigh the potential risks of side effects.
