What is a "spansule"?

A "spansule" refers specifically to a type of medication formulation that consists of small particles of a drug that are coated in such a way that they dissolve at varying rates. This design allows for a controlled release of the medication over time, which can enhance therapeutic effects and improve adherence by reducing the frequency of dosing.

This method of drug delivery is particularly beneficial for medications that require a prolonged effect, as it helps maintain more stable drug levels in the bloodstream. The varying rates at which the coated particles dissolve can be tailored to the needs of the patient, making spansules a valuable option in pharmacotherapy.
