Understanding Delayed-Release Medications: Benefits & How They Work

Many medications come in delayed-release versions to even out their bloodstream concentration. Rather than resulting in high concentration peaks after you've taken a dose followed by lower concentration valleys before your next dose is due, this form provides a steadier amount of the drug. Another reason for extended release medications is to decrease the number of daily doses, thus increasing overall compliance to the prescription. Lastly, some medications are designed for a slow release so they do not dissolve for absorption until they have reached the small intestine, which prevents stomach irritation.
