FERROYES CAPSULES (Each capsule contains Carbonyl Iron/Zinc Sulphate/Folic Acid 100mg/1mg/15mcg /25mg/61.8mg)

Dosage

Children: Refer to the specific carbonyl compound for appropriate dosing guidelines in paediatric populations, as this also varies significantly.

Adults: Refer to the specific carbonyl compound for appropriate dosing guidelines, as doses can vary widely based on the compound's use and formulation.

Mechanism of action

Carbonyl compounds can undergo nucleophilic addition reactions due to the electrophilic nature of the carbonyl carbon. In biochemical pathways, carbonyl groups may interact with various nucleophiles, including amino acids in proteins, leading to modifications that can affect enzyme activity and cellular signaling pathways.

Pharmacodynamics

The pharmacodynamics of carbonyl compounds depend on their specific structure and the biological targets they interact with. Aldehydes and ketones can influence metabolic processes, including glycolysis and the Krebs cycle, through their roles as substrates or inhibitors. They may also participate in redox reactions, affecting cellular energy production and oxidative stress.

Pharmacokinetics

The pharmacokinetics of carbonyl compounds vary widely depending on their molecular structure, including absorption, distribution, metabolism, and excretion (ADME) properties. Many carbonyl compounds are lipophilic, which can influence their absorption and distribution in biological tissues. Metabolism often occurs through oxidation or reduction reactions, and excretion typically involves the renal system.

Pregnancy

Carbonyl compounds may pose risks to fetal development, and their use should be carefully evaluated during pregnancy.

Breast-feeding

It is advisable to avoid carbonyl compounds during breastfeeding unless the benefits outweigh the risks, as they may be excreted in breast milk.

Storage

Store in a cool, dry place away from light and moisture, and ensure containers are tightly sealed to prevent degradation.

Indications

• Folate deficiency
• Megaloblastic anemia
• Prevention of neural tube defects in pregnancy
• Supplementation in patients on certain medications (e.g., methotrexate)

Dosage

Children: Refer to the BNF for Children for appropriate pa

Adults: Refer to specific guidelines or the BNF for appropriate adult dosing based on the indication.

Mechanism of action

Folate functions as a coenzyme in the conversion of homocysteine to methionine, a process that is vital for DNA synthesis and repair. It is involved in the one-carbon metabolism pathway, where it acts as a carrier of one-carbon units necessary for the synthesis of purines and thymidylate, thus supporting the production of nucleotides and DNA. This mechanism is particularly important in rapidly dividing cells.

Pharmacodynamics

Folate is critical for the formation of red blood cells and the proper functioning of the nervous system. It aids in the production of nucleic acids, which are essential for cell proliferation. Folate deficiency can lead to impaired DNA synthesis, resulting in megaloblastic anemia characterized by the presence of large, immature red blood cells in the bloodstream. Adequate folate levels are also associated with reduced risk of neural tube defects in developing fetuses.

Pharmacokinetics

Folate is absorbed in the proximal part of the small intestine, primarily in the jejunum, and is transported in the bloodstream bound to plasma proteins. It undergoes hepatic metabolism and is stored mainly in the liver. The elimination half-life varies, but dietary folate can be retained in the body for several weeks. Excess folate is excreted through the urine. The bioavailability of folate from food sources is lower compared to synthetic folic acid found in supplements.

Interactions

• folates+fluorouracil: Severe (increases risk of toxicity)
• folates+antiepileptics: Moderate (decreases concentration)
• folates+fosphenytoin: Moderate (decreases concentration)
• folates+phenobarbital: Moderate (decreases concentration)
• folates+phenytoin: Moderate (decreases concentration)
• folates+primidone: Moderate (decreases concentration)
• sulfasalazine+folates: Unknown (decreases absorption)

Pregnancy

Folate is essential for fetal development and is often recommended to prevent neural tube defects.

Breast-feeding

Folate is generally safe during breastfeeding, as it is important for both maternal and infant health.

Storage

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