Enhanced blood glucose-lowering effect & increased susceptibility to hypoglycaemia w/ anti-hyperglycaemic medicinal products, ACE inhibitors, disopyramide, fibrates, fluoxetine, MAOIs, pentoxifylline, propoxyphene, salicylates & sulphonamide antibiotics. Reduced blood glucose-lowering effect w/ corticosteroids, danazol, diazoxide, diuretics, glucagon, INH, oestrogens, progestogens, phenothiazine derivatives, somatropin, sympathomimetic medicinal products (eg, epinephrine, salbutamol, terbutaline), thyroid hormones, atypical antipsychotic medicinal products (eg, clozapine & olanzapine) & PIs. Signs of adrenergic counter-regulation may be reduced or absent w/ sympatholytic medicinal products eg, β-blockers, clonidine, guanethidine & reserpine. Insulin: Blood glucose-lowering effect of insulin may either be potentiated or weakened by β-blockers, clonidine, lithium salts or alcohol. Pentamidine may cause hypoglycaemia, which may sometimes be followed by hyperglycaemia. Lixisenatide: May reduce the rate of absorption of orally administered drugs especially drugs of either narrow therapeutic ratio or those that require careful clinical monitoring.
