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.
Known as safe vehicles for drugs, excipients also help give pills a uniform consistency. 1  Some claim that itâs possible to produce a drug or supplement without excipients like magnesium stearate, which begs the question why theyâre used when more natural alternatives are available. But that may not be the case.
