Diffusion of interferon beta in Iran and its utilization in Tehran.

PURPOSE

There are few studies on the diffusion of expensive new therapies in low- or middle-income countries. The objectives of this study were to describe the diffusion of interferon beta for the treatment of patients with multiple sclerosis (MS) in Iran and to analyze its use in a cohort of 890 patients in Tehran registered in the Iranian MS Society (IMSS) registry.

METHODS

Data on the diffusion of interferon beta drugs from 2000 to 2004 in Iran were obtained from the Ministry of Health (MOH). Data on the utilization of interferon beta in selected patient groups were collected from routine clinical data of the IMSS in a sample of population in Tehran province from 2003 to 2005.

RESULTS

Interferon beta had a rapid diffusion in Iran during the study period, and it was used in all 28 provinces in 2004, however, much less in the poor provinces. Interestingly, interferon beta was prescribed to 68% of the patients in Tehran registered in the IMSS registry during 2003-2005. The usage of interferon beta as registered in the IMSS was higher (p < 0.0001) among insured than uninsured patients.

CONCLUSION

The use of interferon beta treatment has grown considerably in Iran. In Tehran, interferon beta seems to be mainly used by young ambulatory patients with relapsing-remitting MS, indicating a rational drug use.
