Types of medications used in Arthritis Analgesics Non-steroidal anti-inflammatory drugs (NSAIDs) Cox-2 inhibitors Corticosteroids Disease-modifying anti-rheumatic drugs (DMARDs) Biologic response modifiers (BRMs).
NSAIDs Making safer choices What is bpac? NSAIDs ( Non Steroidal Anti-Inflammatories) can be associated with serious adverse effects in susceptible patients Paracetamol is the first choice as an analgesic
NSAIDs Making safer choices Naproxen (up to 1000mg per day) or ibuprofen (up to 1200mg per day) are recommended as first line NSAIDs based on cardiovascular risk Lowest effective dose, for the shortest possible time. Your age and the condition being treated needs to be considered
How NSAIDs work The cyclo-oxygenase (COX-1 and COX-2) enzymes produce prostaglandins (Pg) following the metabolism of omega-6-polyunsaturated fatty acid (arachidonic acid). Pg are chemical messengers that mediate inflammation, fever and the sensation of pain. Analgesic and anti-inflammatory effects of NSAIDs are produced through the prevention of Pg production by inhibition of COX activity.
Cox-1 and Cox-2 The difference Cox-1 are widely distributed in the body, but concentrated in the cells of the stomach, kidneys and endothelium and in platelets Pg catalysed by COX-1 activity control renal perfusion, promote platelet aggregation and provide gastroprotection by regulating mucous secretion. Inhibition of COX-1 can cause adverse GI effects.
Cox-1 and Cox-2 The difference COX -2 is induced by inflammation and is present in macrophages, leukocytes and synovial cells. Pg formed via COX-2 activity mediate pain, inflammation, fever and inhibit platelet aggregation NSAIDs that inhibit both COX -1 and 2 are called Non-Selective NSAIDs, while those that inhibit COX-2 enzymes are termed COX-2 inhibitors
NSAIDs and COX inhibition Ibuprofen, naproxen and diclofenac are non-selective, however diclofenac inhibits more COX-2 than Cox-1 Meloxicam low dose mainly inhibits COX-2, as dose increases then COX-1 is increasingly inhibited. Funded with Special Authority. Celecoxid and etoricoxib COX 2 inbibitors. Not funded.
Adverse Effects of NSAIDs Cardiovascular COX-2 were developed because of less GI, but found that COX-2 activity blocks platelet aggregation (opposite to Aspirin) so more chance of a MI Gastrointestinal increased risk with long acting formulations Renal failure Block COX-2 then reduce blood flow to kidney Problem in dehydration Bigger problem in diabetes Hypersensivity reactions
Paracetamol Compared to NSAIDs Minimal GI toxicity Little effect on blood pressure No association with MI No interaction with the anti-platelet effect of aspirin.
All medicines have risks and benefits Benefits Risks
Reducing the Risk of NSAID use Make sure that if you buy OTC products they don t contain NSAIDs Consider risk factors CV Disease, CKD, duodenal ulcers Watch for other products that may interact with NSAIDs ACE inhibitors, diuretics, warfarin, dabigatran, aspirin Talk to your medical team
Cardiovascular Risk Factors Previous Cardiovascular event Heart Failure (double risk Triple Whammy) Increase systolic blood pressure 2-3 mmHg
Gastrointestinal Complications GI risks double with NSAIDs (COX-1 produces protective gastric mucous) Take NSAIDS with food or milk so stomach is not empty May take a PPI prophylactically regularly
Complementary Therapies Likely Effective Glucosamine sulphate (osteoarthritis) SAMe (osteoarthritis) Possibly Effective (Selection) Acupuncture (osteoarthritis) Avocado (osteoarthritis) Beta-carotene (osteoarthritis) Borage (Rheumatoid arthritis) Bromelain (osteoarthritis) Fish Oil (Rheumatoid arthritis) NZ Green Lipped Mussel (Osteo and Rheumatoid arthritis)
