4 Drug and Medication Information

4.1 Therapeutic Uses

Exptl Ther: ... Therapy of acute water diarrhea is reported in 94 male patients, aged 6-59 yr, of whom 49 were given a standard dextrose (glucose) based formula, to a total dose of 105-1719 ml/kg, and 45 were given the same soln with added alanine 90 uM/l, to a total dose of 60-1035 ml/kg. All patients were also given iv injections of replacement soln and oral tetracycline. The median stool output/kg body weight during the initial 24 hr of treatment until diarrhea stopped was reduced in those given the soln containing alanine as compared to controls. Intake of oral rehydration soln was reduced in those given alanine. Two patients given alanine soln and 18 given the standard treatment required unscheduled rapid iv replacement soln to correct signs of dehydration during oral therapy.

5.3 Mechanism of Action

L-Alanine is a non-essential amino acid that occurs in high levels in its free state in plasma. It is produced from pyruvate by transamination. It is involved in sugar and acid metabolism, increases immunity, and provides energy for muscle tissue, brain, and the central nervous system. BCAAs are used as a source of energy for muscle cells. During prolonged exercise, BCAAs are released from skeletal muscles and their carbon backbones are used as fuel, while their nitrogen portion is used to form another amino acid, Alanine. Alanine is then converted to Glucose by the liver. This form of energy production is called the Alanine-Glucose cycle, and it plays a major role in maintaining the body's blood sugar balance.
