Phenytoin (Epanutin) — epilepsy’s 1938 patriarch: still real in status epilepticus loading and stable maintenance, but pharmacology’s classic handful — nonlinear kinetics (tiny dose changes leap levels), narrow window managed by blood levels, gum hyperplasia (oral hygiene is armor), fetal hydantoin syndrome, enzyme-induction chaos (contraceptive failure), and tube-feed absorption blocking.
