Study information
Scientific title
Influence of drug containing ginger extract on arthritic pain and gastropathy in patients with osteoarthritis: a randomised active controlled clinical trial
Acronym
Study hypothesis
Traditional non-steroidal anti-inflammatory drugs (NSAIDs) inhibit COX-1,2 expression leading to the lack of prostaglandins (PG). PG play a crucial role in mechanisms of mucosal defense. This drug containing ginger extract inhibits COX-2 and increases PG production in gastric mucosa. It seems to be an alternative to traditional NSAIDs especially in patients with osteoarthritis with risk factors of NSAID-induced gastropathy.
Ethics approval
Local Ethics Committee of Central Scientific Research Institute of Gastroenterology approved on the 31st August 2007

Condition
Osteoarthritis, NSAID-induced gastropathy
Intervention
The patients were randomised in two groups, using methods of envelopes, to:
1. Group ZG (n = 21): ginger and glucosamine combination (Zinaxin Glucosamine: 170 mg ginger extract [Zingiber officinalis, EV.EXT 35] and 500 mg glucosamine, as glucosamine sulphate, per capsule, Ferrosan AS, Denmark) 2 capsules orally daily
