Troches, or lozenges, are confections made into various forms and then dried.

The vehicle or excipient consists of Powdered Gum Tragacanth or Sugar with flavoring - in some cases orange flower water, in others tolu, nutmeg, vanilla, etc.

The active ingredients are mixed with the diluent or vehicle and made into a plastic mass with the particular excipient, Water or Syrup. The mass is rolled out to the requisite thickness, and the disks formed by cutting through it with a punch or troche-cutter. The troches are then dried by exposure.

The size and weight of the troche are regulated by the thickness of the mass and the diameter of the cutter.

The official Troches vary in weight from Gm. 0.5 to 1.5.
