What is the preferred method for administering INH?

The preferred method for administering isoniazid (INH) is orally, typically in tablet form. This route of administration is favored due to its effectiveness in delivering the medication directly to the systemic circulation, allowing for consistent absorption and utilization by the body in treating tuberculosis. Oral formulation also makes it more convenient for patients, who can take it at home without the need for medical supervision.

Other methods, such as intravenous injection, are not commonly utilized for INH because the oral route provides sufficient bioavailability for its intended purpose in tuberculosis treatment. Topical application is also not applicable, as INH is not intended for any dermatological use. Inhalation through a nebulizer might suggest a delivery method for certain respiratory conditions, but it is not the standard practice for INH administration in pulmonary tuberculosis treatment.
