Introduction
Euro Glucose Oral Powder 100% is a simple sugar (monosaccharide) generated during phosynthesis involving water, carbon and sunlight in plants. It is produced in humans via hepatic gluconeogenesis and breakdown of polymeric glucose forms (glycogenolysis). It circulates in human circulation as blood glucose and acts as an essential energy source for many organisms through aerobic or anaerobic respiration and fermentation. It is primarily stored as starch in plants and glycogen in animals to be used in various metabolic processes in the cellular level. Its aldohexose stereoisomer, dextrose or D-glucose, is the most commonly occurring isomer of glucose in nature. L-glucose is a synthesized enantiomer that is used as a low-calorie sweetener and laxative. The unspecified form of glucose is commonly supplied as an injection for nutritional supplementation or metabolic disorders where glucose levels are improperly regulated. Euro Glucose Oral Powder 100% is listed on the World Health Organization's List of Essential Medicines.
Uses
Euro Glucose Oral Powder 100% is a form of glucose used for caloric supply and the replenishment of fluid in total parenteral nutrition and other therapies as well as for the treatment of hypoglycemic episodes.
Euro Glucose Oral Powder 100% pharmaceutical formulations (oral tablets, injections) are indicated for caloric supply and carbohydrate supplementation in case of nutrient deprivation. It is also used in metabolic disorders such as hypoglycemia.
Associated Conditions
Pharmacodynamics
Blood glucose is an obligatory energy source in humans involved in various cellular activities, and it also acts as a signalling molecule for diverse glucose-sensing molecules and proteins. Euro Glucose Oral Powder 100% undergoes oxidation into carbon dioxide, water and yields energy molecules in the process of glycolysis and subsequent citric cycle and oxidative phosphorylation. Euro Glucose Oral Powder 100% is readily converted into fat in the body which can be used as a source of energy as required. Under a similar conversion into storage of energy, glucose is stored in the liver and muscles as glycogen. Euro Glucose Oral Powder 100% stores are mobilized in a regulated manner, depending on the tissues' metabolic demands. Oral glucose tablets or injections serve to increase the supply of glucose and oral glucose administration is more effective in stimulating insulin secretion because it stimulates the incretin hormones from the gut, which promotes insulin secretion.
Mechanism of Action
Euro Glucose Oral Powder 100% supplies most of the energy to all tissues by generating energy molecules ATP and NADH during a series of metabolism reactions called glycolysis. Glycolysis can be divided into 2 main phases where the preparatory phase is initiated by the phosphorylation of glucose by a hexokinase to form glucose 6-phosphate. The addition of the high-energy phosphate group activates glucose for subsequent breakdown in later steps of glycolysis and is the rate-limiting step. Products end up as substrates for following reactions, to ultimately convert C6 glucose molecule into two C3 sugar molecules. These products enter the energy-releasing phase where total of 4ATP and 2NADH molecules are generated per one glucose molecule. The total aerobic metabolism of glucose can produce up to 36 ATP molecules. This energy-producing reactions of glucose is limited to D-glucose as L-glucose cannot be phosphorlyated by hexokinase. Euro Glucose Oral Powder 100% can act as precursors to generate other biomolecules such as vitamin C. It plays a role as a signaling molecule to control glucose and energy homeostasis. Euro Glucose Oral Powder 100% can regulate gene transcription, enzyme activity, hormone secretion, and the activity of glucoregulatory neurons. The types, number and kinetics of glucose transporters expressed depends on the tissues and fine-tunes glucose uptake, metabolism, and signal generation in order to preserve cellular and whole body metabolic integrity .
Absorption
Polysaccharides can be broken down into smaller units by pancreatic and intestinal glycosidases or intestinal flora. Sodium-dependent glucose transporter SGLT1 and GLUT2 (SLC2A2) play predominant roles in intestinal transport of glucose into the circulation. SGLT1 is located in the apical membrane of the intestinal wall while GLUT2 is located in the basolateral membrane, but it was proposed that GLUT2 can be recruited into the apical membrane after a high luminal glucose bolus allowing bulk absorption of glucose by facilitated diffusion . Oral preparation of glucose reaches the peak concentration within 40 minutes and the intravenous infusions display 100% bioavailability.
Volume of Distribution
The mean volume of distribution after intravenous infusion is 10.6L.
Route of Elimination
Euro Glucose Oral Powder 100% can be renally excreted.
Half Life
The approximate half-life is 14.3 minutes following intravenous infusion. Gut glucose half-life was markedly higher in females (79 ± 2 min) than in males (65 ± 3 min, P < 0.0001) and negatively related to body height (r = -0.481; P < 0.0001).
Clearance
The mean metabolic clearance rate of glucose (MCR) for the 10 subjects studied at the higher insulin level was 2.27 ± 0.37 ml/kg/min at euglycemia and fell to 1.51±0.21 ml/kg/ at hyperglycemia. The mean MCR for the six subjects studied at the lower insulin level was 1.91 ± 0.31 ml/kg/min at euglyglycemia.
Toxicity
Oral LD50 value in rats is 25800mg/kg. The administration of glucose infusions can cause fluid and/or solute overloading resulting in dilution of the serum electrolyte concentrations, over-hydration, congested states, or pulmonary oedema. Hypersensitivity reactions may also occur including anaphylactic/anaphylactoid reactions from oral tablets and intravenous infusions.
