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 ...
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 ...
MS Contin tablets are known as misties, and the 100 mg extended-release tablets as greys and blockbusters. The " speedball " can use morphine as the opioid component, which is combined with cocaine, amphetamines , methylphenidate , or similar drugs.
Between 1950s and 1980s, there were four drug release systems developed for oral and transdermal applications: dissolution, diffusion, osmosis, and ion-exchange controlled release. [3] Later in the 1980s, the Lupron Depot technology further advanced the field by offering zero-order and long-term release systems. The intranasal route gained ...
Metadate CD capsules contain two types of beads: 30% are immediate-release, and the other 70% are evenly sustained release. [187] 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. [188] [189]
The definition of recovery remains divided and subjective in drug rehabilitation, as there are no set standards for measuring recovery. [35] The Betty Ford Institute defined recovery as achieving complete abstinence as well as personal well-being [36] while other studies have considered "near abstinence" as a definition. [37]
This allows for much more precise drug delivery over an extended period of time, which results in much more predictable pharmacokinetics. However, osmotic release systems are relatively complicated, somewhat difficult to manufacture, and may cause irritation or even blockage of the GI tract due to prolonged release of irritating drugs from the ...
Formoterol, also known as eformoterol, is a long-acting β 2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol has an extended duration of action (up to 12 h) compared to short-acting β 2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h.
