drugs for MS pain | NSAIDs, acetaminophen, tramadol, opioid analgesics like hydrocodone |
drugs to decrease inflammation (and limit tissue damage) | prednisone, NSAIDs, hydroxychloroquine (dec type I IFN production), MTX, biological agents like anti-TNF monoclonal Ab |
NSAID gastropathy | dyspepsia & epigastric pain common esp. in elderly, those with h/o prev GI bleed or on warfarin/heparin. start on PPI or misoprostol concomitantly |
NSAID nephropathy | acute renal failure, nephrotic syndrome or interstitial nephritis. inc risk in elderly, those with CHF or already poor renal function, pts on diuretics/ACEI |
COX2 selective NSAIDs | may lessen gastropathy but have inc risk of cardiac and embolic events like stroke |
tx of RA | simple analgesics don't work. starts with low dose steroids for bridge therapy to more slow-acting agents. then try hydroxychloroquine (+/-) sulfasalazine then low-dose MTX with supplemental folate then etanercept & infliximab for most severe RA |
urate lowering tx | only indicated for those with renal stones, multi recurrent attacks or visible tophi on exam. allopurinol is prototype. uricosurics: probenecid & sulfinpyrazone if pt has nl renal function and no h/o kidney stones. |

tx of SLE | NSAIDs for arthritis & mild serositis. antimalarials for fatigue, lupus skin dz, arthritis & serositis. topical steroids for skin dz. high dose steroids for cytopenias, severe plum dz, vasulitis & neurospcyh manifestations |
when to use anti-CD20 like rituximab in SLE | when pt is having life-threatening complications like nephritis. also cyclophosphamide, azathioprine (OJO with allopurinol = inc myelosuppression) or mycophenolate mofetil |
post-menopausal osteoporosis | EtOH and smoking cessation. fall prevention strategies. calcium & vitamin D supplementation. bisphosphonates like alendronate, rPTH like teriparatide, estrogen or SERM and calcitonin |
