Once youâre eligible for Medicare, youâll have an initial enrollment period to sign up for Medicare. For most people, the initial enrollment period starts 3 months before their 65th birthday and ends 3 months after their 65th birthday.
Excipient. An excipient is generally a pharmacologically inactive substance formulated with the active ingredient of a medication. Excipients are commonly used to bulk up formulations that contain potent active ingredients, to allow convenient and accurate dispensation of a drug substance when producing a dosage form.
Some excipients help a drug to disintegrate into particles small enough to reach the bloodstream more quickly. Others protect the stability of the product so it will be at maximum effectiveness at the time of use (they function as preservatives).
