Comment: Barbiturates may well maximize adverse outcomes, including respiratory despair, produced by harmful doses of TCAs. With therapeutic doses of TCAs, barbiturates enhance metabolism and reduce blood concentrations of TCAs.
Griseofulvin. Phenobarbital seems to interfere Along with the absorption of orally administered griseofulvin, Consequently lowering its blood amount.
