It is used for drug compounds with high solubility in water. [6] When the drug is covered with some slow dissolving coat, it will eventually release the drug. Instead of diffusion, the drug release depends on the solubility and thickness of the coating. Because of this mechanism, the dissolution will be the rate limiting factor for drug release ...
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 ...
Additionally, slow-release dosage forms may maintain concentrations within an acceptable therapeutic range over a longer period, whereas quick-release dosage forms may have sharper peaks and troughs in serum concentration. [8] The rate of dissolution is described by the Noyes–Whitney equation as shown below:
There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys. There exist several classes of diuretic, and each works in a distinct way. Alternatively, an antidiuretic, such as vasopressin (antidiuretic hormone), is an agent or drug which reduces the excretion of water in urine.
Depot injections can be created by modifying the drug molecule itself, as in the case of prodrugs, or by modifying the way it is administered, as in the case of oil/lipid suspensions. Depot injections can have a duration of action of one month or greater and are available for many types of drugs, including antipsychotics and hormones.
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.
Loop diuretics may also precipitate kidney failure in patients concurrently taking an NSAID and an ACE inhibitor—the so-called "triple whammy" effect. [19] Because furosemide, torsemide and bumetanide are technically sulfa drugs, there is a theoretical risk that patients sensitive to sulfonamides may be sensitive to these loop diuretics. This ...
Methadone, sold under the brand names Dolophine and Methadose among others, is a synthetic opioid used medically to treat chronic pain and opioid use disorder. [7] Prescribed for daily use, the medicine relieves cravings and opioid withdrawal symptoms. [10]
