Lozenge

Lozenge

A lozenge refers to a form of medication that is designed to dissolve slowly in the mouth. It is also known as a troche and is typically diamond-shaped. Lozenges are used to deliver both systemic and local effects in the mouth and throat.

History

The term lozenge is derived from the French word 'losange', which refers to the geometric shape. The use of lozenges in medicine dates back to the Egyptian times, where they were used for a variety of ailments.

Medical Use

Lozenges are commonly used to provide relief from symptoms of the common cold such as cough, sore throat, and congestion. They are also used in the treatment of oral thrush and mouth ulcers. The medication is slowly released as the lozenge dissolves in the mouth, providing a local effect.

Types of Lozenges

There are several types of lozenges, including:

• Antitussive lozenges: These contain ingredients like dextromethorphan and are used to suppress coughs.
• Anaesthetic lozenges: These contain a local anaesthetic to numb the throat and relieve pain.
• Antibacterial lozenges: These contain an antibacterial agent to help fight infection.
• Antifungal lozenges: These are used to treat oral thrush.

Preparation

Lozenges are typically prepared by compressing the active ingredients along with fillers and binders. The mixture is then shaped into a lozenge using a tablet press.
