UNIMINERAL PAED 1G

Dosage

Children: Refer to specific drug monographs for paediatric dosing information, as micrograms are a measurement unit rather than a medication.

Adults: Refer to specific drug monographs for adult dosing information, as micrograms are a measurement unit rather than a medication.

Pregnancy

Safety in pregnancy has not been established. Use only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

Use with caution. The effects on a nursing infant are unknown, and it may be excreted in breast milk.

Storage

Store in a cool, dry place away from light. Ensure it is kept out of reach of children.

Dosage

Children: Refer to the specific drug's prescribing information for paediatric dosing guidelines.

Adults: Refer to the specific drug's prescribing information for exact dosages.

Mechanism of action

The mechanism of action varies widely among drugs classified as 'multiple.' Generally, these drugs may act through various pathways, including receptor agonism or antagonism, enzyme inhibition, modulation of neurotransmitter levels, and alteration of ion channel activity. Specific mechanisms depend on the individual drug's pharmacological class and intended use.

Pharmacodynamics

Pharmacodynamics for multiple drugs encompasses a wide range of actions, from agonist effects on receptors to inhibition of metabolic pathways. These pharmacological actions can lead to therapeutic effects or adverse reactions, depending on dosage, duration of treatment, and patient factors.

Pharmacokinetics

Pharmacokinetics for multiple drugs varies significantly. Generally, this includes absorption, distribution, metabolism, and excretion profiles that determine the drug's bioavailability and half-life. Each drug's pharmacokinetic parameters can influence dosing schedules and therapeutic monitoring.

Indications

• Vitamin deficiency syndromes (e.g., scurvy for vitamin C deficiency, rickets for vitamin D deficiency)
• Support for immune function
• Antioxidant support
• Bone health maintenance
• Vision health
• Energy metabolism support

Dosage

Children: Refer to the BNF for Children for specific vitamin dosing guidelines, which depend on age and nutritional requirements.

Adults: Refer to specific vitamin guidelines as dosage varies significantly depending on the type of vitamin and individual needs.

Mechanism of action

Vitamins function primarily as coenzymes or precursors for coenzymes in enzymatic reactions. For instance, B vitamins are involved in energy metabolism, while vitamins A, C, D, E, and K support various physiological functions including vision, antioxidant activity, calcium regulation, and blood clotting. Each vitamin has a unique mechanism of action based on its structure and role in the body.

Pharmacodynamics

Vitamins exert their effects at the cellular level, influencing metabolic pathways, gene expression, and immune responses. For example, vitamin D regulates calcium and phosphate homeostasis, while vitamin A is crucial for vision and immune function. Deficiencies in vitamins can lead to a range of disorders, highlighting their importance in maintaining health.

Pharmacokinetics

The pharmacokinetics of vitamins vary widely. Fat-soluble vitamins (A, D, E, and K) are stored in liver and adipose tissues and can be released into circulation as needed. Water-soluble vitamins (B-complex and C) are not stored and must be consumed regularly, with excess amounts excreted in urine. Absorption rates, half-lives, and distribution can also differ based on the specific vitamin and individual metabolic factors.

Interactions

• tretinoin+vitamin: Severe (increases risk of vitamin toxicity)
• retinoids+vitamin: Severe (increases risk of vitamin toxicity)
• retinoids+vitamin: Moderate (increases risk of toxicity)
• carbamazepine+vitamin: Unknown (decreases effects)
• cobicistat+vitamin: Unknown (increases exposure)
• vitamin D substances+digoxin: Unknown (increases risk of toxicity)
• idelalisib+vitamin: Unknown (increases exposure)
• clarithromycin+vitamin: Unknown (increases exposure)

Pregnancy

Consult healthcare professional before use. Vitamin supplementation during pregnancy should be carefully managed to avoid hypervitaminosis.

Breast-feeding

Consult healthcare professional before use. Some vitamins can pass into breast milk and may affect the infant.

Storage

Store in a cool, dry place, away from direct sunlight. Ensure it is kept out of reach of children.
