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 ...
Sustained-release (SR) and extended-release (XL) formulations have been designed to slow down absorption resulting in t max of 3 hours and 5 hours, respectively. [109] Absolute bioavailability of bupropion is unknown but is presumed to be low, at 5–20%, due to the first-pass metabolism. As for the relative bioavailability of the formulations ...
An influential cognitive-behavioral approach to addiction recovery and therapy has been Alan Marlatt's (1985) Relapse Prevention approach. [62] Marlatt describes four psycho-social processes relevant to the addiction and relapse processes: self-efficacy , outcome expectancy, attributions of causality, and decision-making processes.
Around the same time, Brunnstrom also described the process of recovery, and divided the process into seven stages. As knowledge of the science of brain recovery improved, intervention strategies have evolved. Knowledge of strokes and the process of recovery after strokes has developed significantly in the late 20th century and early 21st century.
Biovail's sustained-release tablets will compete with AstraZeneca's Seroquel XR. In December 2008, AstraZeneca notified shareholders that the FDA had asked for additional information on the company's application to expand the use of sustained-release quetiapine for treatment of depression.
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.

Recovery from benzodiazepine dependence tends to take a lot longer than recovery from alcohol, [47] [48] but people can regain their previous good health. [47] [medical citation needed] A review of the literature regarding benzodiazepine hypnotic drugs concluded that these drugs cause an unjustifiable risk to the individual and to public health.
