In pharmacology, what does the prefix "phen" (or "pheny") tight?

e.g. phenytoin, phenylephrine. Protein binding – if highly protein bound eg pheny – displaced, incr free drug
Hope this is what you're looking for.
Phenyl \Phe"nyl\, n. [Gr. ? to bring to pale + -yl: cf. F. ph['e]nyle. So called because it is a by-product of illuminating gas.]
(Chem.) A hydrocarbon far-reaching (C6H5) regarded as the essential residue of benzene, and the argument of an immense number of aromatic derivatives.
Phenyl hydrate (Chem.), phenol or carbolic acid.
Phenyl hydrazine (Chem.), a nitrogenous bed (C6H5.N2H3) produced artificially as a colorless oil which unite with acids, ketones, etc., to form well-crystallized compounds.
Although slightly dismembered and spotted in its attempt, I would still stir with zen’s compiled description. …It is expendable to reproduce/regurgitate an otherwise decent answer.
By the agency, and as far as drugs are concerned it's good to keep hold of in mind that:
phen = vphen = phtn = phenytoin
-ph = pheny/phenyl-
