droxidopa |
<chemical> A precursor of noradrenaline that is used in the treatment of parkinsonism. The racaemic form (dl-threo-3,4-dihydroxyphenylserine) has also been used, and has been investigated in the treatment of orthostatic hypotension. There is a deficit of noradrenaline as well as of dopamine in parkinson's disease and it has been proposed that this underlies the sudden transient freezing seen usually in advanced disease. Administration of dl-threo-3,4-dihydroxyphenylserine has been claimed to result in an improvement in this phenomenon but controlled studies have failed to demonstrate improvement. (reynolds jef(ed): martindale: the extra pharmacopoeia (electronic version). Micromedex, inc, englewood, co, 1995) Pharmacological action: antiparkinson agents. Chemical name: L-Tyrosine, beta,3-dihydroxy-, threo- (12 Dec 1998) |

droplet
|
A small spherical particle of any liquid; in meteorology, particularly a water droplet. There is no defined size limit separating droplets from drops of water, but it is sometimes convenient to denote two disparate size ranges, such as the oft-used distinction of liquid cloud particles (droplets) from liquid precipitation (drops), thereby implying that a maximum diameter of 0.2 mm (0.008 in.) is the limit for droplets. See cloud droplet, drizzle drop, drop, raindrop.
