Scientific rationale and available literature on Myo-inositol in the respiratory field.

Myo-inositol: key points overview

A focused selection of mechanisms described in the scientific literature and results reported in clinical studies.

Osmolyte and hydration

Myo-inositol acts as an osmolyte, meaning it is able to attract and retain water, contributing to the maintenance of adequate hydration of the mucus layer and the epithelial surface.

Mucociliary clearance

In a retrospective pilot study conducted in patients with bronchiectasis, aerosol administration of myo-inositol, twice daily for 15 days, resulted in a significant reduction in mucus solid content.

Pulmonary surfactant and neonatal respiratory medicine

Myo-inositol, mainly in the form of phosphatidylinositol, is a key component of pulmonary surfactant. Its role has been investigated in pre-clinical and clinical studies involving preterm infants with respiratory distress syndrome (RDS).

Myo-inositol in combination con N-acetil-L-cisteina (NAC)

Reduction of MIOX activity

Experimental studies suggest that NAC may modulate the expression and activity of MIOX (myo-inositol oxygenase), a key enzyme involved in myo-inositol catabolism, potentially contributing to increased bioavailability.

Enhanced mucociliary clearance

NAC acts as a mucolytic and mucoregulator, helping to reduce mucus viscosity and facilitate its elimination.
The osmolyte activity of myo-inositol promotes mucus hydration, further supporting mucociliary clearance.

Support of inflammation control

Myo-inositol and NAC may contribute to the modulation of acute and chronic inflammatory processes, acting on different molecular pathways such as PI3K/AKT and NF-κB, and protecting cells
from oxidative stress.

Myo-inositol in combination with Alpha-lactalbumin

Micronutrient absorption

Alpha-lactalbumin is a whey protein studied for its nutritional properties and its ability to influence the intestinal absorption mechanisms of specific micronutrients

In association with myo-inositol

Data available in the literature indicate that alpha-lactalbumin may enhance the intestinal absorption of myo-inositol, improving its systemic availability when administered orally.
