Hh. Koch et al., Use of acarbose for eliminating the interval between meal consumption and insulin injection in patients with Type 1 diabetes, DIABET NUTR, 12(3), 1999, pp. 195-201
This double-blind, placebo-controlled, cross-over study investigated whethe
r acarbose therapy enables patients with Type 1 diabetes to administer insu
lin injections at the same time as meals without adverse glycaemic conseque
nces, thus negating the need for an injection-meal interval (IMI), The vali
d-case population was 15, All patients were well controlled on insulin ther
apy and diet, Each patient underwent four 14-d treatment sequences: IMI of
0 min+acarbose; IMI of 30 min + acarbose; IMI of 0 min + placebo; IMI of 30
min + placebo. There was a 1-wk, placebo-controlled washout period between
each treatment. A 50 mg acarbose or placebo tablet was taken with each of
three meals for the first 3 d of each treatment; this was increased to 100
mg three times daily on the remaining 11 d, Blood samples were taken betwee
n 08.00 and 09.00 h at the end of each treatment sequence, during the fasti
ng state and at the following times after breakfast: 30, 60, 120 and 180 mi
n, The primary target variable was 1-hr postprandial blood glucose level af
ter 14 d, The mean increase in 1-hr postprandial blood glucose level using
an IMI of 0 min + acarbose was 51.1+/-53.2 mg/dl, compared with 46.6+/-50.4
mg/dl using a 30-min IMI + placebo, Data provided strong evidence that aca
rbose prevents the marked increase in postprandial glucose level normally o
bserved when insulin is administered with a meal, Acarbose may thus be usef
ul for patients with Type 1 diabetes who find IMIs inconvenient. (C) 1999,
