DXM

|
DXMDextromethorphan, a cough suppressant, sometimes misused as a recreational drug.
RELATED TERMS--------------------------------------
Dextromethorphan
An oral cough suppressant available in the US without a prescription but which is sometimes abused as a recreational drug. Dextromethorphan (DXM) is chemically related to codeine and acts on the brain to suppress cough, but it does not have the pain relieving and addictive properties of codeine. DXM is an ingredient in more than 125 nonprescription cough and cold medications, including forms of Robitussin, Coricidin and Vicks.
Cough
A rapid expulsion of air from the lungs typically in order to clear the lung airways of fluids, mucus, or material.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Dwarf
Someone with dwarfism, which is now more correctly called short stature.
Dwarfism, achondroplastic
A genetic disorder of bone growth, achondroplasia is the most common cause of short stature with disproportionately short limbs -- dwarfism with short arms and legs. There is a typically large head with prominence of the forehead (frontal bossing), underdevelopment (hypoplasia) of the midface with cheekbones that lack prominence, and a low nasal bridge with narrow nasal passages. The fingers are short and the ring and middle fingers diverge giving the hand a trident (three-pronged) appearance.
Dwarfism, pituitary
Dwarfism caused by a lack of growth hormone, usually due to malfunction of the pituitary gland. Children with growth hormone deficiency may grow normally for the first two to three years of life but they then fall behind their peers in height. They are normally proportioned. This is a key point. Treatment is with human growth hormone given in childhood. Also known as hypopituitary dwarfism, hypopituitarism, panhypopituitarism, and growth hormone deficiency.
Dwarfism, thanatophoric
A form of short-limbed (micromelic) dwarfism that usually causes death within the first few hours after birth. Thanatophoric dysplasia is due to a lethal mutation (change) in the same gene that produces achondroplasia, a familiar and far more common form of short-limbed dwarfism that is compatible with life.
Dx
Abbreviation standing for diagnosis, the determination of the nature of a disease.
DXM
Dynacin
Brand name for minocycline.
Dynein
A family of microtubule motor proteins that derive energy from ATP (adenosine triphosphatase) activity. The dyneins also form arms on the outer tubules of cilia and flagella.
DYS
Symbol for familial dysautonomia or a prefix denoting an inability or lack of function, as in dyspraxia (lack of ability to adequately control muscle movements).
Dyscrasia
Any disease condition, especially in hematology, as in "blood dyscrasias."
Dysentery, amebic
Dysentery (inflammation of the intestine) with ulcers in the colon due to infection with an ameba (Entamoeba histolytica). This single-celled parasite is transmitted to humans via contaminated water and food.
