A racemate (often called a racemic mixture) is a mixture of equal amounts of both enantiomers of a chiral drug. Chirality in drugs most often arises from a carbon atom attached to 4 different groups, but there can be other sources of chirality as well.

In chemistry, a racemic mixture, or racemate (/ r eɪ ˈ s iː m eɪ t, r ə-, ˈ r æ s ɪ m eɪ t /), is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule. The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid.A sample with only a single enantiomer is an enantiomerically ...

Medical Definition of racemic : of, relating to, or constituting a compound or mixture that is composed of equal amounts of dextrorotatory and levorotatory forms of the same compound and is optically inactive — compare dl-

racemic epinephrine is a mixture of the inactive "d" and the active "l" enantiomers of epinephrine. The racemic mixture was originally thought to provide the same dilatory effect with fewer adverse reactions than "l" epinephrine. beta adrenergic activity results in relaxation of smooth muscle.

We can just think of this as “left-handed epi”. Racemic epinephrine, on the other hand (no pun intended) contains both L-Epinephrine, AND D-Epinephrine. The “D” stands for dextrorotary, which we can think of as “right-handed Epi”. The D-Epinephrine is simply a mirror image of the L-epinephrine.

Racemic acid, or, more properly, racemic tartaric acid, is a mixture of equal amounts of dextrorotatory and levorotatory tartaric acids; it is customarily designated D - or L -, or (+)- or (–)-, respectively, tartaric acid.

A racemate(often called a racemic mixture) is a mixture of equal amounts of both enantiomers of a chiral drug. Chirality in drugs most often arises from a carbon atom attached to 4 different groups, but there can be other sources of chirality as well. Single enantiomers are sometimes referred to as single isomersor stereoisomers.
