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 ...
Benzodiazepines, opioids, alcohol, and any other drug may induce prolonged withdrawal and have similar effects, with symptoms sometimes persisting for years after cessation of use. Psychosis including severe anxiety and depression are commonly induced by sustained alcohol, opioid, benzodiazepine, and other drug use which in most cases abates ...
SHALLOW part of curve —> ultimate excretion of drug, which is dependent on the release of the drug from tissue compartments into the blood. The longer half-life is called the terminal half-life and the half-life of the largest component is called the dominant half-life. [39]
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 ...
Dihydrocodeine in both extended-release and immediate-release form is also sometimes used for maintenance treatment as an alternative to methadone or buprenorphine in some European countries. [148] Dihydrocodeine is an opioid agonist. [149] It may be used as a second-line treatment. [150]
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.
