Trecator is the brand name for a medication called Ethionamide. It is an antibiotic that is primarily used in the treatment of tuberculosis (TB).

Ethionamide is an important component of the standard treatment regimen for TB. It is used in combination with other antibiotics to effectively treat the infection and prevent the development of drug resistance.

Antibiotic works by inhibiting the growth of the bacteria that cause TB. It targets specific enzymes involved in the synthesis of bacterial proteins, disrupting their function and preventing the bacteria from multiplying.

This medication is available in the form of tablets and is typically taken orally. The dosage and duration of treatment will depend on the specific regimen, which may vary based on the individual's age, weight, and the severity of the TB infection.

It is important to note that Trecator is usually reserved for use in drug-resistant strains of TB or cases where other first-line treatments have been ineffective. It is not typically used as a first-line therapy due to its potential side effects and the need for close monitoring during treatment.
