[26]

(57) Abstract

[27]

This invention relates to the field of chemical- pharmaceutical industry,

[28]

specifically a new tuberculosis treatment that contains, as an active ingredient,

[29]

4-thioureido- iminomethylpyridinium perchlorate at a therapeutically effective

[30]

and safe level and pharmaceutically acceptable excipients. In addition, this

[31]

treatment relates to a method of the preparation of the new drug, providing a

[32]

high yield of the new treatment. The new treatment has a higher tuberculostatic

[33]

activity (200 times as high) and lower toxicity (2.4 times as low), as compared to

[34]

a prototype drug, and is stable during long-term storage. This medicament may

[35]

be used for treating and preventing all forms of pulmonary and extrapulmonary

[36]

ΤΒ by using the new treatment in combination with other ΤΒ drugs.
