classify anti tubercular drugs. write chemical name, structure , uses,brand name of INH

Anti-tubercular drugs are classified into two main categories: First-line drugs and Second-line drugs.

First-line drugs include:

1. Isoniazid (INH)
2. Rifampicin (RIF)
3. Pyrazinamide (PZA)
4. Ethambutol (EMB)
5. Streptomycin (STM)

Second-line drugs include:

1. Fluoroquinolones
2. Injectable second-line drugs
3. Thioamides
4. Cycloserine
5. Aminoglycosides
6. XDR-TB drugs

Now, let's focus on Isoniazid (INH):

Chemical Name: Isonicotinylhydrazide

Structure: The chemical structure of Isoniazid can be represented as C6H7N3O. It consists of a pyridine ring attached to a hydrazide functional group.

Uses: Isoniazid is primarily used as a first-line treatment for tuberculosis. It is often used in combination with other anti-tubercular drugs. It is also used as a preventive therapy for people who have been in close contact with TB patients.

Brand Names: Some of the common brand names for Isoniazid include Laniazid and Nydrazid.

Please note that the chemical structure of a compound is best represented visually, and cannot be accurately described in text. For the chemical structure of Isoniazid, I would recommend referring to a trusted source such as a chemistry textbook or online database.
