Pastilles consist of solidified liquids or solid solutions in single-dose form. This means that they have a different structure than tablets or dragees . The first finished medicinal products available in Germany were offered in lozenge form.

Manufacturing

Pastilles are made by pouring a liquid into ready-made powder forms. Then the still liquid pastilles are gently dried. The active ingredients contained in the dried liquid are slowly released when chewing or sucking and can be absorbed by the mucous membranes or enter the stomach with the saliva. This is the only way to process completely different substances. These substances include:

• essential and fatty oils,
• liquid - also alcoholic - tinctures and extracts ,
• Dry extracts,
• soluble and insoluble substances or drugs .

Auxiliary materials

Difficulties that many of these substances cause, for example when making tablets or other conventional drug forms, can be avoided in this way. Often pastilles are made on the basis of gum arabic . Gum arabic is obtained from the gum arabic tree , the Senegel acacia. Gum arabic offers decisive advantages in the manufacture of pastilles. As a hydrocolloid , it offers the possibility of emulsifying and suspending and binds flavors such as essential oils and aromas. The gum arabic keeps the mucous membranes of the mouth and throat moist with a protective film.
