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.
Pharmaceutical regulations and standards require that all ingredients in drugs, as well as their chemical decomposition products, be identified and shown to be safe. Often, more excipient is found in a final drug formulation than active ingredient, and practically all marketed drugs contain excipients.
