UN health agency adds 4 TB drugs to pre-qualified list, easing access to treatment

23 March 2007

At a time when the tuberculosis virus is producing increasingly drug-resistant strains, the United Nations health agency today added four new medicines to its list of pre-qualified products, one of them the first to be included for strains of TB that are resistant to standard treatment.

“The addition of these four medicines will reinforce efforts to scale up access to anti-tuberculosis medicines in high-burden areas and in countries which may have only limited capacity to control and monitor pharmaceuticals,” the UN World Health Organization (WHO) said in a statement.

Manufactured by the generic producer MacLeods of India, the medicines are the first TB products to be added to the list in two years and will increase the choice of quality products available to procurement agencies to tackle the disease that killed an estimated 1.6 million people in 2005. Nearly 9 million others were suffering from TB that year.

One of the new products, Cycloserine, is particularly important because it is a second-line medicine, necessary for cases that are resistant to standard treatment. There is also a fixed-dose combination, ethambutol + isoniazid, which is the first product combining these two basic medicines to be pre-qualified. The other two medicines are Ethambutol and Pyrazinamide.

Product assessment reports on the quality and bioequivalence of these newly pre-qualified products and manufacturing site inspection findings will soon also be published. These procedures make the WHO prequalification process the most transparent of all similar quality assurance programmes to date.
