Difflam Antibacterial and Anti-inflammatory Lozenges contain the active ingredients Benzydamine, and Cetylpyridinium Chloride.

Benzydamine belongs to a family of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs). They work to reduce pain and inflammation in the body by reducing the production of hormone-like substances that promote the inflammatory response. Benzydamine does not treat the underlying cause of the inflammation, however, and should not be used for extended periods of time without medical advice. Benzydamine also possesses local anaesthetic activity to further enhance pain relief.

Cetylpyridinium Chloride is an antibacterial agent designed to prevent the growth of bacteria in the throat and mouth. It may help to reduce the severity and duration of a sore throat.
