Clinical studies

Evidence from randomised, controlled trials has shown that Difflam fulfils many of the requirements of an ideal oral anti-inflammatory, analgesic, and anaesthetic agent.6,7

Topical Benzydamine Hydrochloride is widely used, well tolerated and has minimal risk of side effects.3
It is also suitable for the treatment of children and adults of all ages.4

For the treatment and prevention of sore throats

Topical Benzydamine Hydrochloride has been shown to provide significant symptom relief as measured by reduced pain, reduced inflammation, and a reduced use of analgesics in patients.6

After dental surgery

Studies have supported the anti-inflammatory, analgesic and anaesthetic effects of Difflam after dental surgery. The anti-inflammatory effects of Benzydamine Hydrochloride have also been suggested to accelerate the healing process.10

For post-tonsillectomy and post-operative sore throat

Benzydamine Hydrochloride has also been shown to prevent sore throat post-operatively for as long as 24 hours, whilst evidence supports the use of Difflam in both adults and children.6,7

Routine prophylactic use of Difflam has been shown to help prevent ulceration and pain during radiotherapy.8,9

Topical Benzydamine Hydrochloride has been shown to have significant effects in preventing ulceration and pain during radiotherapy, even on severe mucositis with severe pain.8,9

For relief from pains, sprains, strains and sports injuries

Studies have supported the anti-inflammatory and analgesic effects of Difflam 3% Cream and Difflam - P 3% Cream associated with an excellent penetration of the skin and an early reduction in odema and pain as a consequence.11

Difflam acts fast to provide lasting relief from pain.3-7

Benzydamine Hydrochloride

Difflam contains the active ingredient Benzydamine Hydrochloride which, after topical administration, is absorbed locally becoming concentrated in the inflamed tissue.1

Benzydamine Hydrochloride is classed as a locally acting, non-steroidal

anti-inflammatory drug (NSAID), but has a different mechanism of action from other NSAIDs. In fact, Benzydamine Hydrochloride has local anaesthetic effects and gastroprotective effects (where topical administration is not associated with the gastrointestinal irritation seen with systemic NSAIDs).

Benzydamine Hydrochloride exerts an anti-inflammatory and analgesic effect by stabilising the cellular membrane and inhibiting prostaglandin synthesis. Studies have shown that the analgesic action of Benzydamine Hydrochloride is independent from its anti-inflammatory action.2-5

The information above outlines the findings of a number of studies supporting Difflam and its active ingredient, Benzydamine Hydrochloride.
