There are many reports on the effects of intravenous lipid emulsion (ILE) as an antidote in drug toxicity. Haloperidol (HAL) is a butyrophenone antipsychotic agent which is highly lipophilic. Hypotension is an important adverse effect of HAL administration and overdose. ⋯ ILE 20% at the dose of 18 ml/kg could return the reduced mean arterial pressure and diastolic blood pressure sooner than the other doses and normal saline. In conclusion, ILE could reverse HAL-induced hypotension same as the other lipophilic drugs. However, the clinical use of ILE for this purpose needs more evaluation to determine its exact indication and safety.

Diabetic peripheral neuropathy (DPN) is widely considered as a degenerative complication of diabetic patients. The clinical effectiveness of folic acid (FA) on DPN is uncertain. The objective of the present study was to determine the effect of FA in DPN using electromyography (EMG), histopathological examination, immunohistochemistry, inclined plane test, and malondialdehyde (MDA) levels as a marker for lipid peroxidation in experimental diabetic rats. ⋯ The scores for the inclined plane test were lower in the diabetes group and higher in the FA-treated group than the control group. The MDA levels were significantly lower in the FA-treated group when compared with the diabetes group. The study suggests that FA can protect diabetic rats against DPN and that the underlying mechanism for this may be related to improvement of the expression of NGF and lower MDA levels.
