Thecommonlyusedglucoseloweringdrugsinthemanagementofdiabetesarediscussedbelow: 3.4.1.Biguanides Metformin is the only drug of the biguanide group available on the Fiji Essential Medicine Formulary (EMF). It lowers blood glucose by suppressing hepatic glucose production and increasing tissue sensitivity to insulin. It should be considered as the first line treatment for all patientssufferingfromdiabetesandisthepreferreddruginobesetype2diabeticpatients. Itisclearedfromthebodypredominantlybyrenalexcretion.Itaccumulatesinrenalimpairment andshouldbeusedwithcautioninpatientswithserumcreatinineofmorethan200umol/Lor eGFR of <45ml/min.

Itcancauselacticacidosisinsituationssuchasischemicheartdisease,congestiveheartfailure and renal impairment. It should be stopped for 48 hours before surgery or administration of contrast radiography and only resumed once urine output and renal function have returned to acceptablelevelasstatedavove.Thereisnoriskofhypoglycaemiawhenusedalone. Itsmajoradverseeffectsare:anorexia,nausea,abdominaldiscomfortanddiarrhoea. Metformin is given orally 2Ͳ3 times a day and taken with or after meals to avoid gastric intolerance.Thedosevariesfrom500mgdailytoamaximumof3g/dayindivideddoses.Most 8 physicianslimitthedoseto2gramsdailybecause,athigherdoses,gastrointestinalsideeffects aremorecommon.Itisadvisabletobeginwithasmallerdosetostartwithand increasethe dose gradually to facilitate compliance; otherwise the development of gastrointestinal side effectswillstopthepatientfromtakingthedrug. 3.4.2.Sulphonylureas Twoofthesecompounds,glibenclamideandglipizide,areavailableontheFijiEMF.Theyacton thepancreaticbetaͲcellsandinduceinsulinsecretion.Glibenclamideispredominantlyclearedby the kidneys and it is recommended in younger patients.
