Complimentary and alternative medications (CAMs) in RA Brad Butt Managing partner Cooleman Court Pharmacy WESTON
Objectives • Which CAMs are our patients seeking information on • What evidence is there for their use • Possible interactions – disease state/medication
CAMs in RA • Fish oils • Trend towards Krill oil • Tumeric/curcumin • Others…
Fish Oils • EPH/DHA is the key – polyunsaturated 3 fatty acids. • Flaxseed oil – ALA 5-10% EPA and 1-5% DHA only1&2 • Quality – TGA v GOED (global organisation for EPA and DHA 3)
Fish oils benefits • Anti-inflammatory effect – complex! • PG/TXA/LT – signalling molecules in inflammation • Arachidonic acid (AA) is the major substrate for their synthesis3-5 • EPA/DHA leads to reduced conversion of AA • Decreases leukocyte chemotaxis reduced pro-inflammatory cytokines (TNF and IL subtypes) 6-7 • 3.8g EPA + 2g DHA 10 capsules daily
Fish oil benefits • Anti depressant effect • Evidence for EPA/DHA in major depressive episodes • Meta analysis – 15 randomised, double blind, placebo controlled trials (916 patients) at doses up to 2200mg EPA/DHA per day concluded effective against primary depression8
Fish oil precautions • Recent clinical studies show no increase in bleed risk; even in patients on aspirin and warfarin with doses up to 7g/day of EPA/DHA9 • Should be done under medical supervision1 • Doses <12g/day need medical supervision1 • Hypomania can occur with fish oil in bipolar patients10 • Seafood allergy theoretically problematic
Krill oil – fad or not? • Krill oil has been hugely popular • Comprehensively out sells fish oil • There is a lack of good clinical evidence • Doses need to be in excess of 1500mg daily • 1500mg krill oil 226mg EPA 122mg DHA • General feel is that evidence is for fish oils so recommend fish oil at appropriate dose first for best results
Curcumin/Tumeric • May assist with the down regulation of inflammatory mediators • Reduces joint inflammation in RA • Symptomatically works quickly • Lack of large clinical trials • COX2 inhibition believed to be MOA • Less GIT/BP issues associated with curcumin (v NSAID)
Curcumin precautions • Bile duct obstruction • Anti coagulants • Can reduce BGL – hypoglycaema risk • May increase stomach acid secretion
Others • Glucosaime • Minimum 4 week time to effect • Shell fish allergy precaution • 1500mg daily required • +/- condroitin/MSN • Green lipped muscle extract • Anti-inflammatory effect • Small evidence for use
Others • St Johns Wart • Used for depression • Effect similar to a SSRI • Variability between brands/batches as plant derived – numerous environmental factors may affect outcome of dose • Many interactions with other Rx medications • Reasonable evidence for its use/effect
