Thorens oral drops solution contain colecalciferol (vitamin D3). Vitamin D3can be found in some foods and is produced by the body when the skin is exposed to sunlight. Vitamin D promotes the absorption of calcium in the kidneys and intestine, aiding in bone formation. Vitamin D deficiency is the main cause of rickets (inadequate mineralization of bones in children) and osteomalacia (inadequate mineralization of bones in adults).

Thorens oral drops solution is used to prevent and treat vitamin D3deficiency in adults, adolescents, and children with identified risk of vitamin D3deficiency.

Thorens oral drops solution may also be used as an adjunct to specific medication for bone mass loss.
