Clinical monograph: myoinositol
BNF-referencedMyo-inositol is a naturally occurring carbohydrate and a form of inositol, which is a six-carbon cyclic sugar alcohol. It plays a crucial role in cellular processes, particularly in the formation of phosphoinositides that are involved in cell signaling pathways. Myo-inositol is commonly used as a dietary supplement and has garnered attention for its potential benefits in various health conditions, including polycystic ovary syndrome (PCOS) and metabolic disorders.
Indications
- Polycystic ovary syndrome (PCOS)
- Insulin resistance
- Metabolic syndrome
- Mood disorders
- Neurodegenerative diseases
Dosage
Children: Dosage for paediatric patients is not established; refer to BNF for Children for specific guidance.
Adults: The typical adult dose of myo-inositol is 2 to 4 grams daily, usually divided into two doses.
Mechanism of action
Myo-inositol functions primarily as a precursor in the biosynthesis of inositol phosphates, which are critical for cell signaling. It contributes to the synthesis of 1D-myo-inositol hexakisphosphate and other inositol phosphates, facilitating the regulation of cellular functions such as insulin signaling and lipid metabolism. Myo-inositol also plays a role in the modulation of neurotransmitter signaling, particularly in the central nervous system.
Pharmacodynamics
Myo-inositol has been shown to influence insulin sensitivity and may help in restoring ovarian function in women with PCOS. It acts as a second messenger in various hormonal signaling pathways, particularly those involving insulin and follicle-stimulating hormone (FSH). The drug's action can lead to improved ovarian response and metabolic profiles in affected individuals.
Pharmacokinetics
Myo-inositol is well-absorbed when administered orally, with a bioavailability that may vary based on the formulation. It is distributed throughout the body and has a half-life that supports multiple dosing regimens. Myo-inositol is eliminated primarily through renal excretion, and its metabolism is closely linked to the pathways of inositol phosphate metabolism.
Pregnancy
The safety of myoinositol during pregnancy has not been established. Consultation with a healthcare professional is advised.
Breast-feeding
Myoinositol is generally considered safe during breastfeeding, but it is recommended to consult a healthcare provider for personalized advice.
Storage
Store at room temperature, away from moisture and direct sunlight. Keep out of reach of children.
