Benactyzine is an anticholinergic drug that was used as an antidepressant in the treatment of depression and associated anxiety before it was pulled from the U.S. market by the FDA due to its ineffectiveness. 
Its use for these indications was limited by
side effects such as dry mouth and nausea, and at high doses it can cause more severe symptoms such as deliriant and hallucinogenic effects. 
Brand names have included:
Suavitil, Phebex, Phobex, Cedad, Cevanol, Deprol, Lucidil, Morcain, Nutinal, Parasan. While there was some tentative evidence when combined with meprobamate with the medication no longer available it is not clinical important. 
History [ edit ]
Benactyzine was brought to market in the US in 1957 by
Merck under the tradename, Suavitil.
