Indications

• Liver function tests
• Hepatic encephalopathy
• Liver cirrhosis
• Hepatitis
• Fatty liver disease
• Drug metabolism monitoring

Dosage

Children: Dosing for pediatric patients should always be referenced from established guidelines or the BNF for Children, as it varies significantly based on age, weight, and specific liver-related conditions.

Adults: Dosing for liver-related therapies depends on the specific condition and drug being utilized. Refer to specific drug monographs for detailed dosing information.

Mechanism of action

The liver functions through various pathways, including the hepatic portal system, where nutrients absorbed from the gastrointestinal tract are transported to the liver for processing. Hepatocytes, the functional cells of the liver, engage in metabolic processes such as gluconeogenesis, glycogenolysis, and lipid synthesis. The liver also produces proteins such as albumin and clotting factors, and detoxifies drugs and metabolites through enzymatic reactions involving cytochrome P450 enzymes.

Pharmacodynamics

Pharmacodynamics in relation to liver function often involves the liver's capacity to metabolize drugs and regulate their pharmacological effects. It affects the bioavailability of drugs, their half-life, and overall efficacy. Hepatic dysfunction can lead to altered drug metabolism, resulting in increased drug accumulation and potential toxicity.

Pharmacokinetics

Pharmacokinetics related to liver function involves the absorption, distribution, metabolism, and excretion (ADME) of substances. After oral administration, drugs are absorbed in the gastrointestinal tract and transported via the portal vein to the liver. The liver metabolizes drugs through phase I (oxidation, reduction, hydrolysis) and phase II (conjugation) reactions. Metabolites are then excreted into bile or transported to the kidneys for renal excretion. Factors such as hepatic blood flow, enzyme activity, and liver disease can significantly impact these processes.

Pregnancy

Liver function is crucial during pregnancy, and any liver disease can significantly impact both maternal and fetal health. Careful monitoring and management of liver function are essential.

Breast-feeding

Liver health is important during breastfeeding, as liver function affects the metabolism and clearance of drugs that may be excreted in breast milk.

Storage

Liver tissue should be handled and stored in accordance with laboratory guidelines, ensuring it is preserved properly for analysis or transplantation.
