title: Immunotoxicity of clonazepam in adult albino rats.
abstract: Clonazepam as an addictive drug is studied to elucidate its destructive effects on rats' immune system. The aim of the current work was to study the immunologic changes induced by sub-chronic administration of clonazepam for three weeks followed by a withdrawal period in adult male albino rats. Seventy-two Sprague Dawley rats were divided into three equal groups. The first group was used as control; the second and third groups were treated with clonazepam. Six rats from each group were sacrificed weekly. Data showed that clonazepam induced a significant suppression in the level of IFN-gamma cortisol production, total splenocytes count and lymphocytes transformation induced by PHA mitogen along the experimental period especially in the third group. However, subchronic doses of clonazepam increased the production of IL-10 in both treated groups. Moreover, significant DNA damage in the peripheral blood lymphocytes of both treated groups was observed along the duration of the study. In conclusion, the immune system responses can be adversely affected to a greater extent by sub-chronic administration of clonazepam and should be prescribed cautiously as patients may turn addict to it.
