GLUCOPECT

Indications

• Hypoglycemia
• Caloric supplementation in patients unable to eat
• Fluid replacement therapy
• Parenteral nutrition

Dosage

Children: Paediatric doses must be determined based on clinical condition and specific needs. Refer to the BNF for Children for appropriate dosing information.

Adults: The dosage of dextrose in adults varies based on clinical condition and route of administration. For hypoglycemia, intravenous dextrose 50% (D50W) is commonly administered. Refer to the BNF for specific dosing guidelines.

Mechanism of action

Dextrose supplies energy to tissues by generating ATP and NADH through glycolysis, where glucose is phosphorylated by hexokinase to form glucose 6-phosphate. This activates glucose for breakdown, ultimately converting glucose into energy molecules. Dextrose also plays a role in gene transcription, enzyme activity, and hormone secretion, regulating glucose homeostasis and cellular metabolic integrity.

Pharmacodynamics

Blood glucose acts as a crucial energy source for cellular activities and functions as a signaling molecule. It is oxidized into carbon dioxide and water, producing energy through glycolysis, the citric cycle, and oxidative phosphorylation. Dextrose can be converted into fat for energy storage and is stored as glycogen in the liver and muscles. Its administration, particularly orally, enhances insulin secretion due to stimulation of incretin hormones.

Pharmacokinetics

Dextrose is rapidly absorbed in the gastrointestinal tract, leading to a quick elevation of blood glucose levels. It is distributed throughout the body and can be utilized by various tissues for energy. The metabolism of dextrose primarily occurs in the liver, where it can be stored as glycogen or converted into fat. Renal excretion may occur when blood glucose levels are excessively high.

Mechanism of action

Hydroxide ions act primarily as bases, neutralizing acids to form water and salts. They participate in various biochemical pathways, including selenium metabolism and the degradation of reactive oxygen species. Hydroxide can influence enzyme activity and stability by altering the pH of the environment, thereby affecting metabolic reactions.

Pharmacodynamics

Hydroxide ions can impact biological processes by changing the local pH, which influences enzyme activity, ion transport, and the solubility of other compounds. Their ability to neutralize acids can help regulate physiological pH, contributing to homeostasis in living organisms.

Pharmacokinetics

As an inorganic ion, hydroxide does not undergo traditional pharmacokinetic processes like absorption, distribution, metabolism, or excretion. Instead, it is rapidly equilibrated in biological fluids and participates in acid-base reactions, having immediate effects on the local environment.

Mechanism of action

Kaolin acts by adsorbing various substances within the gastrointestinal tract. It binds to toxins, bacteria, and other pathogens, which helps to prevent their absorption into the bloodstream. This action reduces the irritation of the intestinal lining and helps restore normal bowel function.

Pharmacodynamics

The pharmacodynamic effects of kaolin include its ability to absorb and retain moisture, which can help solidify feces. Its adsorbent properties may also contribute to its therapeutic effects in gastrointestinal disturbances. By binding to pathogens and toxins, kaolin may reduce inflammation and irritation in the gut.

Pharmacokinetics

Kaolin is not absorbed systemically when administered orally; it remains in the gastrointestinal tract where it exerts its effects. The elimination of kaolin occurs through fecal excretion. Its local action in the gut allows it to exert therapeutic benefits without significant systemic exposure.

Adverse effects

• Constipation
• Abdominal discomfort
• Nausea
• Vomiting

Precautions

• Use with caution in patients with gastrointestinal obstruction
• Monitor for potential constipation, especially in elderly patients

Pregnancy

Kaolin is generally considered safe during pregnancy, but it should be used under medical supervision.

Breast-feeding

Kaolin is not known to be excreted in breast milk and is considered safe during breastfeeding.

Storage

Store in a cool, dry place away from light. Keep out of reach of children.

Formulations

• Oral suspension
• Powder

Indications

• Metabolic acidosis
• Lactic acidosis
• Support in shock or severe dehydration
• Exercise physiology research

Dosage

Children: Refer to clinical guidelines for specific dosing recommendations based on the clinical condition being treated.

Adults: Refer to clinical guidelines for specific dosing recommendations based on the clinical condition being treated.

Mechanism of action

Lactic acid primarily functions by contributing to the acid-base balance in the body. It can serve as a substrate for gluconeogenesis in the liver and is utilized in the Cori cycle, where it is converted back to glucose. Furthermore, lactic acid can act as a signaling molecule in various physiological processes, influencing metabolism and cellular responses during hypoxic conditions.

Pharmacodynamics

Lactic acid dissociates into lactate and hydrogen ions in solution, which can lead to a decrease in pH (acidosis) when produced in excess. Its accumulation in the body is indicative of anaerobic metabolism, often observed during intense exercise or in conditions of oxygen deprivation. The body can buffer the effects of lactic acid through bicarbonate and other mechanisms, maintaining homeostasis.

Pharmacokinetics

Lactic acid is rapidly absorbed and distributed throughout the body. It is metabolized primarily in the liver, where it can be converted to glucose or further metabolized to carbon dioxide and water. The elimination half-life of lactate varies depending on the metabolic state of the individual and the presence of underlying conditions. Renal function also plays a role in the clearance of lactate from the body.

Adverse effects

• Nausea
• Vomiting
• Abdominal pain
• Diarrhea
• Hypersensitivity reactions

Precautions

• Use with caution in patients with renal impairment
• Monitor for signs of metabolic acidosis
• Caution in patients with liver disease

Pregnancy

Lactic acid is generally regarded as safe, but clinical use should be evaluated on a case-by-case basis during pregnancy.

Breast-feeding

Considered safe for use during breastfeeding, but consult healthcare provider for individual cases.

Storage

Store at room temperature, away from direct sunlight and moisture.

Formulations

Mechanism of action

Pectin acts as an adsorbent that binds to bacteria, toxins, and other irritants in the intestinal mucosa. It decreases the pH in the intestinal lumen, providing a soothing effect on irritated mucosa. In the presence of dietary cholesterol, pectin effectively lowers plasma cholesterol levels by reducing its absorption from the intestinal tract.

Pharmacodynamics

Pectin increases the viscosity and volume of stools, which aids in managing constipation and diarrhea. Its effects on body components, including cholesterol levels, vary depending on the type of pectin and its composition. While some studies suggest potential benefits in cholesterol reduction, the data remains inconclusive and further research is needed.

Pharmacokinetics

Pectin is not extensively absorbed in the gastrointestinal tract due to its polysaccharide nature, which allows it to remain largely intact as it passes through. Its effects are primarily local within the gut, where it exerts its actions on stool consistency and adsorbs various substances.

Pregnancy

Pectin is generally considered safe during pregnancy. However, it is advisable to consult a healthcare provider before use.

Breast-feeding

Pectin is considered safe during breastfeeding. It is recommended to consult a healthcare provider prior to use.

Storage

Store in a cool, dry place, away from direct sunlight and moisture.

Formulations

• Powder
• Capsules
• Liquid

Mechanism of action

Glucose 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 two main phases where the preparatory phase is initiated by the phosphorylation of glucose by hexokinase to form glucose 6-phosphate. The addition of the high-energy phosphate group activates glucose for the 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 the 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. These energy-producing reactions of glucose are limited to D-glucose as L-glucose cannot be phosphorylated by hexokinase. Glucose 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. Glucose 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 to preserve cellular and whole body metabolic integrity. Vascular calcification is a hallmark of type 2 diabetes. Glucose stimulates calcification in culture of vascular smooth muscle cells (VSMCs) but the underlying mechanisms remain obscure. We observed that high glucose levels stimulated mouse and human VSMC trans-differentiation into chondrocytes, with increased levels of Sox9, type II collagen, glycosaminoglycan and Runx2 expression, and increased alkaline phosphatase activity and mineralization. These effects were associated with increased expression of IL-1beta, which stimulated alkaline phosphatase and calcification, suggesting that glucose induces chondrocyte differentiation of VSMCs, possibly through IL-1beta activation.

Pharmacodynamics

Blood glucose is an obligatory energy source for humans involved in various cellular activities, and it also acts as a signaling molecule for diverse glucose-sensing molecules and proteins. Glucose undergoes oxidation into carbon dioxide, water, and yields energy molecules in the process of glycolysis and subsequent citric cycle and oxidative phosphorylation. Glucose 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. Glucose 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

Pectin is an adsorbent that binds to bacteria, toxins and other irritants in the intestinal mucosa. Pectin is able to decrease the pH in the intestinal lumen and provides a soothing effect on the irritated mucosa. IN WIDE VARIETY OF TRIALS (SWINE, CHICKENS, RABBITS, RATS & MAN) ORAL PECTIN HAD EITHER NO EFFECT OR INCR PLASMA CHOLESTEROL IN ABSENCE OF DIETARY CHOLESTEROL, BUT EFFECTIVELY LOWERED PLASMA CHOLESTEROL...IN PRESENCE OF EXOGENOUS CHOLESTEROL BY DECR CHOLESTROL ABSORPTION FROM INTESTINAL TRACT.

Pharmacodynamics

Pectin increases viscosity and volume of stools which helps it to be used for constipation and diarrhea. It is reported as well to present lowering effects of different body components. This effect depends on the type of pectin which indicated that this effect is related to the composition of the correspondent pectin. Nonetheless, this data is still unclear and more studies need to be performed to conclude this effect of pectin.
