ABSTRACT
Effect of single graded doses of amitriptyline (4, 8 and 16, mg/kg, p.o.) were observed on blood glucose level in 18 h fasted albino rabbits. All the doses of Amitriptyline produced significant hyperglycemia at 4 h, which attained a peak at 24 h with 16 mg/kg dose and appears to be due to blockade of the uptake of monominergic transmitters across the axoplasmic membrane, It (16 mg/kg) also produced glucose intolerance during early hours probably due to interference with gastrin function.

Blood glucose level was estimated in 18 h fasted albino rabbits following acute feeding of graded doses of mianserin. Mianserin (6.0 mg/kg) produced a gradually increasing hyperglycemic effect which became significant (P < 0.01) at 10 h and onwards. This appears to be due to increased turnover and release of noradrenaline by the drug. The same dose of mianserin also produced glucose intolerance during early hours probably by interfering with gastrin functions.
