Trial of a Sustained Release Form of Amitriptyline (Lentizol) in the Treatment of Depressive Illness

Abstract

The advantages of a new sustained release form of amitriptyline (Lentizol) which can be given in a single dose for the treatment of depressive illness have recently been described by Sims (1972) and Haider (1972). This paper reports a similar double blind cross-over trial in the treatment of depressive illness (ICD 296) of the same substance compared against conventional amitriptyline at an overall higher dosage level.
