Effect of chronic opioid administration on glycosylated haemoglobin levels in heroin addicts.

ABSTRACT

Levels of stable form of HbA1 in blood were estimated in 20 male heroin addicts, so as to assess the effect of chronic opioid use on glucose metabolism. No significant difference in the levels of stable form of HbA1 was observed in the heroin addicts as compared to controls, indicating absence of any long-term impairment of glucose tolerance in heroin addicts.
