Ethambutol Hydrochloride

Introduction

India has also launched an anti-dumping enquiry into the importation of Ethambutol Hydrochloride tuberculosis drug into the country against Chinese and Thai imports. The reason behind this regulatory step is the protection of local pharmaceutical manufacturers against the unfairly priced imports, and the provision of the stable supply of this vital medication.

Characteristics and Therapeutic Use of the Drug.

Ethambutol Hydrochloride is a prescribed antibacterial drug that is a synthetic, water-soluble and heat-resistant medication specifically used to treat tuberculosis. It shows specific action against actively growing microorganisms of Mycobacterium genus including Mycobacterium tuberculosis. The drug is also employed in pulmonary tuberculosis as well as extrapulmonary tuberculosis thus being a versatile element in the treatment of TB.

Mechanism of Action

The action of the drug occurs in a special mechanism that interferes with the synthesis of the cell walls of M. tuberculosis. Ethambutol undermines the structural integrity of the bacterium by acting, specifically, on the polymerization of arabinogalactan, which is an important structural element of the mycobacterial cell wall. This specific action is finally followed by the death of the bacterial cells and this is the therapeutic effect of this action.

Treatment Plan and Management of Resistance.

An important side of Ethambutol treatment is the fact that it should be used only in combination regimens. When used as a monotherapy, bacteria develop resistance quite fast. It is therefore always used in combination with other first-line anti-tuberculosis medications, including isoniazid, rifampicin and pyrazinamide. This joint strategy can be used on two levels: to increase the overall effectiveness of the treatment due to the synergism of their action, and to avoid the appearance of drug-resistant strains of tuberculosis. The mechanism of action is unique and it is complementary to other anti-TB drugs; hence, it is invaluable in the initial stages of treatment as well as in the retreatment regimens.

Conclusion

Being a vital element of standardized TB therapy plans globally, the availability and proper use of Ethambutol Hydrochloride continues to play a key role in managing tuberculosis. The recent trade inquiry in India highlights the role of the drug in the health of the population and the necessity to have a dependable and cost-efficient supply chain of this essential antimicrobial agent.
