Isoniazid, also known as isonicotinic acid hydrazide (INH), is an antibiotic used for the treatment of tuberculosis. [4] For active tuberculosis, it is often used together with rifampicin , pyrazinamide , and either streptomycin or ethambutol . [ 5 ]
During this initial period, Isoniazid is taken alongside pyridoxal phosphate to obviate peripheral neuropathy. Isoniazid is then taken concurrently with rifampicin for the remaining four months of treatment (6-8 months for miliary tuberculosis). A patient is expected to be free from all living TB bacteria after six months of therapy in ...
The duration of action of a drug is the length of time that particular drug is effective. [5] Duration of action is a function of several parameters including plasma half-life, the time to equilibrate between plasma and target compartments, and the off rate of the drug from its biological target.

Isoniazid/rifampicin, also known as isoniazid/rifampin, is a medication used to treat tuberculosis. [1] It is a fixed dose combination of isoniazid and rifampicin (rifampin). [1] It is used together with other antituberculosis medication. [1] It is taken by mouth. [1] It is on the World Health Organization's List of Essential Medicines. [2]
In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. [2] A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor . [ 3 ]
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way.
It is a fixed dose combination of ethambutol, isoniazid, pyrazinamide, and rifampicin. [1] It is used either alone or with other antituberculosis medication. [1]
Onset of action is the duration of time it takes for a drug's effects to come to prominence upon administration. With oral administration , it typically ranges anywhere from 20 minutes to over an hour, depending on the drug in question.
