HALOCUR 0,5 mg/ml

Indications

• Antitumoral therapy
• Fibrotic diseases

Dosage

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

Adults: Refer to the BNF for specific dosing guidelines.

Mechanism of action

Halofuginone inhibits collagen a1(I) and matrix metalloproteinase 2 (MMP-2) gene expression, leading to reduced extracellular matrix deposition and cell proliferation. This inhibition affects tumor stromal support, vascularization, invasiveness, and overall tumor growth.

Pharmacodynamics

Halofuginone selectively regulates stromal cell activation, migration, and collagen type I synthesis. This regulation is essential in the tissue repair process, where excessive collagen deposition can contribute to fibrosis. Its effects on the tumor microenvironment suggest potential applications in managing various malignancies.

Pharmacokinetics

The pharmacokinetics of halofuginone, including its absorption, distribution, metabolism, and excretion profiles, are not extensively detailed in the provided sources. Further studies may be required to elucidate these aspects.

Pregnancy

Halofuginone should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

It is not known whether halofuginone is excreted in human milk. Caution should be exercised when administering to breastfeeding women.

Storage

Store in a cool, dry place, away from light. 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.

Mechanism of action

Halofuginone is a potent inhibitor of collagen a1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also suppresses extracellular matrix deposition and cell proliferation. The profound antitumoral effect of halofuginone is attributed to its combined inhibition of the tumor stromal support, vascularization, invasiveness, and cell proliferation.

Pharmacodynamics

Halofuginone, a fully synthetic small molecule, is a potent and selective regulator of stromal cell activation, cell migration and Collagen type I synthesis, a process that has been identified as a 'master switch' in the body's tissue repair process.
