Repaglinide belongs to the meglitinide class of blood glucose-lowering drugs.
Repaglinide lowers blood glucose by stimulating the release of insulin from the pancreas.
It achieves this by closing ATP-dependent potassium channels in the membrane of the
beta cells. This depolarizes the beta cells, opening the cells' calcium channels, and the
resulting calcium influx induces insulin secretion.
To evaluate the effect of repaglinide as a monotherapy or in combination with metformin on
controlling the fasting plasma glucose, postprandial plasma glucose, HBA1C, and body weight in
61 patients with type 2 diabetes mellitus, (DM).
PATEINTS & METHODS:
During the period between February 2005 and October 2005, the effects of repaglinide
has been reviewed in 61 patients with uncontrolled Type 2 diabetes mellitus (T2DM),
they are divided into two groups depending on their previous treatment , the 1st group
included 43 of them were on metformin while the remaining 18 patients were on diet
only. Weight, HBA1c, FPG and PPG were checked after 3 and 6 months.
It has been found that six months after using Repaglinide in combination with metformin or as a
monotherapy cause significant reduction in HBA1c, from 9.8 to 8.1% (P < 0.01) in 1st group, and
from 7.9 to 6.7%, (P < 0.01) in 2nd group and a significant reduction of FPG from 214.0 mg/dl to
148.5 mg/dl (P < 0.01) in 1st group and from 170.7 mg/dl to 130 mg/dl (P < 0.01) in 2nd group.
While the PPG shows a decrement from 255.6 mg/dl to 178.8 mg/dl, (P < 0.01) in 1st group and
from 248.3 mg/dl to166.1 mg/dl (P < 0.01) in 2nd group. There’s no significant weight gain thus
mean weight rose from 84.4 Kg to 84.6 Kg, (P > 0.2) in 1st group and from 75.1 kg to 76.1 kg (P >
0.2) in 2nd group .
Repaglinide when used as monotherapy or in combination with metformin improve
overall glycemic control and significantly reduced HBA1c but have no significant
change in body weight
