چکیده

Thirty-eight patients who presented with diabetes and a changed state of consciousness satisfied the criteria for lactic acidosis. Sixteen patients were non-ketotic, and 15 of these were receiving phenformin on admission. In all but one of these 15 patients, however, additional renal or cardiovascular abnormalities, or both, could be identified, which supported a multifactorial aetiology for lactic acidosis. Advanced age and cardiovascular and renal disease are absolute contraindications to the use of phenformin in diabetics.

Lactic acidosis and hyperamylasaemia associated with phenformin therapy.

Introduction Lactic acidosis, first described by Clausen (1925), is most frequently seen accompanying hypotension and impaired tissue perfusion, but has been reported in association with many other conditions such as phenformin therapy, non-ketotic diabetic acidosis, ethanol ingestion and glycogen storage disease (Oliva, 1970; Lancet, 1973).

Epidemiology of adverse drug reactions to phenformin and metformin.

Adverse drug reactions (ADRs) to phenformin and metformin reported to the Swedish Adverse Drug Reaction Committee during 1965--77 were analysed in relation to sales and prescription data. The biguanides accounted for 0.6% of all reported adverse drug reactions but for 6% of the fatal cases (all phenformin). Sixty-four ADRs to phenformin and eight to metformin were classified as causal relation ...

Metformin and Lactic Acidosis

Probably the most common mechanism by which metformin elevates blood lactate is by inducing catecholamine release in those who regulate or prescribe it. Caution in restricting the use of metformin for the treatment of type 2 diabetes has been rationalized on the basis of J) its chemical identity as a biguanide, 2) its ability to modify hepatic intermediary metabolism, 3) its administration to i...

Oxygen consumption is depressed in patients with lactic acidosis due to biguanide intoxication

INTRODUCTION Lactic acidosis can develop during biguanide (metformin and phenformin) intoxication, possibly as a consequence of mitochondrial dysfunction. To verify this hypothesis, we investigated whether body oxygen consumption (VO2), that primarily depends on mitochondrial respiration, is depressed in patients with biguanide intoxication. METHODS Multicentre retrospective analysis of data ...
