RINGER-LACTATE FRESENIUS COMBINATION PRODUCT INFUSION

Indications

• Dietary supplementation
• Metabolic disorders
• Energy provision in specific clinical settings

Dosage

Children: Refer to the BNF for Children for specific dosing instructions.

Adults: Refer to the BNF for specific dosing instructions.

Mechanism of action

Hexa functions primarily as a source of energy through beta-oxidation, where it is broken down into acetyl-CoA units that enter the citric acid cycle. This process ultimately leads to the production of ATP, which is essential for cellular energy.

Pharmacodynamics

Hexa contributes to the regulation of metabolic pathways involving fatty acids. It influences energy homeostasis and can impact lipid profiles in the body. The presence of medium-chain fatty acids like hexa can promote ketogenesis, especially in carbohydrate-restricted diets, providing an alternative energy source.

Pharmacokinetics

Hexa is absorbed through the gastrointestinal tract and is rapidly metabolized in the liver. It has a relatively short half-life, and its metabolites are efficiently utilized or excreted by the body. The pharmacokinetic profile may be affected by dietary factors and individual metabolic rates.

Pregnancy

Hexa should only be used in pregnancy if the benefits outweigh the risks. Consult with a healthcare professional.

Breast-feeding

It is unknown if hexa is excreted in human milk. Caution is advised when administering to nursing mothers.

Storage

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

Indications

• Metabolic acidosis
• Lactic acidosis
• Energy substrate in critical illness
• Monitoring tissue perfusion and oxygenation

Dosage

Children: Refer to the BNF for Children for appropriate dosing in paediatric patients.

Adults: Refer to specific guidelines based on clinical context as dosing is highly variable and situation-dependent.

Mechanism of action

Lactate acts as a signaling molecule and energy substrate in various physiological and pathological processes. It is involved in the modulation of several metabolic pathways, including the Cori cycle and Krebs cycle. Lactate also participates in metabolic reprogramming, especially in cancer cells, where it can promote tumor growth and survival by providing an alternative energy source and influencing cellular signaling pathways such as the PI3K/AKT/mTOR pathway.

Pharmacodynamics

Lactate plays a vital role in energy metabolism. It can be oxidized back to pyruvate by lactate dehydrogenase, entering the Krebs cycle for ATP production. In addition to serving as an energy substrate, lactate impacts pH regulation and can influence the function of various immune cells. Its levels can indicate the state of oxygen delivery and utilization in tissues, thus serving as a marker for metabolic stress.

Pharmacokinetics

Lactate is produced primarily in the cytoplasm during glycolysis, with its concentration in the blood reflecting the balance between production and clearance. It is metabolized predominantly in the liver, where it can be converted back to glucose or utilized in the Krebs cycle. Lactate levels can vary based on factors such as exercise, tissue hypoxia, and metabolic conditions.

Pregnancy

Lactate is generally regarded as safe during pregnancy as it is a naturally occurring metabolite in the body, but specific clinical advice should be sought.

Breast-feeding

Lactate is considered safe during breastfeeding as it is a normal component of human metabolism, but consult a healthcare provider for personalized advice.

Storage

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