Modified-release dosage is a mechanism that (in contrast to immediate-release dosage) delivers a drug with a delay after its administration (delayed-release dosage) or for a prolonged period of time (extended-release [ER, XR, XL] dosage) or to a specific target in the body (targeted-release dosage). [1] Sustained-release dosage forms are dosage ...
Controlled or modified-release formulations alter the rate and timing at which a drug is liberated, in order to produce adequate or sustained drug concentrations. [28] The first controlled-release (CR) formulation that was developed was Dexedrine in the 1950s. [13]
The dissolution time can be modified for a rapid effect or for sustained release. Special coatings can make the tablet resistant to the stomach acids such that it only disintegrates in the duodenum, jejunum and colon as a result of enzyme action or alkaline pH. Pills can be coated with sugar, varnish, or wax to disguise the taste ...
Extended-release (or slow-release) formulations of morphine are those whose effect last substantially longer than bare morphine, availing for, e.g., one administration per day. Conversion between extended-release and immediate-release (or "regular") morphine is easier than conversion to or from an equianalgesic dose of another opioid with ...
The drug is expelled via the laser-drilled hole visible on the left side of the tablet. The osmotic-controlled release oral delivery system (OROS) is an advanced controlled release oral drug delivery system in the form of a rigid tablet with a semi-permeable outer membrane and one or more small laser drilled holes in it.

Elizabeth Warren wants President-elect Trump to set conflict-of-interest rules for Elon Musk. Warren called any lack of rules an "invitation for corruption on a scale not seen in our lifetimes."
Metadate CD capsules contain two types of beads: 30% are immediate-release, and the other 70% are evenly sustained release. [185] Medikinet Retard/CR/Adult/Modified Release tablets are an extended-release oral capsule form of methylphenidate. It delivers 50% of the dosage as IR MPH and the remaining 50% in 3–4 hours.
