These include alkali citrate, sodium bicarbonate, potassium citrate, magnesium citrate, and Bicitra (a combination of citric acid monohydrate and sodium citrate dihydrate). Aside from alkalinization of the urine, these supplements have the added advantage of increasing the urinary citrate level, which helps to reduce the aggregation of calcium oxalate stones.Increasing the urine pH to around 6.5 provides optimal conditions for dissolution of uric acid stones. Increasing the urine pH to a value higher than 7.0 may increase the risk of calcium phosphate stone formation, though this concept is controversial since citrate does inhibit calcium phosphate crystallization. Testing the urine periodically with nitrazine paper can help to ensure the urine pH remains in this optimal range. Using this approach, stone dissolution rate can be expected to be around 10 mm (0.4 in) of stone radius per month. Slaked lime
It decreases urinary calcium when combined with food rich in oxalic acid such as green leafy vegetables. Diuretics
One of the recognized medical therapies for prevention of stones is the thiazide and thiazide-like diuretics, such as chlorthalidone or indapamide. These drugs inhibit the formation of calcium-containing stones by reducing urinary calcium excretion. Sodium restriction is necessary for clinical effect of thiazides, as sodium excess promotes calcium excretion. Thiazides work best for renal leak hypercalciuria (high urine calcium levels), a condition in which high urinary calcium levels are caused by a primary kidney defect. Thiazides are useful for treating absorptive hypercalciuria, a condition in which high urinary calcium is a result of excess absorption from the gastrointestinal tract.
Steroids may be injected into affected joints during the initial period of RA, prior to the use of DMARDs or oral steroids.Non-NSAID drugs to relieve pain, like paracetamol may be used to help relieve the pain symptoms; they do not change the underlying disease. The use of paracetamol may be associated with the risk of developing ulcers.NSAIDs reduce both pain and stiffness in those with RA but do not affect the underlying disease and appear to have no effect on peoples long term disease course and thus are no longer first line agents. NSAIDs should be used with caution in those with gastrointestinal, cardiovascular, or kidney problems. Rofecoxib was withdrawn from the global market as its long-term use was associated to an increased risk of heart attacks and strokes. Use of methotrexate together with NSAIDs is safe, if adequate monitoring is done. COX-2 inhibitors, such as celecoxib, and NSAIDs are equally effective. A 2004 Cochrane review found that people preferred NSAIDs over paracetamol. However, it is yet to be clinically determined whether NSAIDs are more effective than paracetamol.The neuromodulator agents topical capsaicin may be reasonable to use in an attempt to reduce pain. Nefopam by mouth and cannabis are not recommended as of 2012 as the risks of use appear to be greater than the benefits.Limited evidence suggests the use of weak oral opioids but the adverse effects may outweigh the benefits.Alternatively, physical therapy has been tested and shown as an effective aid in reducing pain in patients with RA.
