Gold

Gold salts are used to treat rheumatoid arthritis. The exact mechanism of action of gold preparations is unknown, but it is believed that the mononuclear phagocyte system is gradually blocked during treatment. The concentration of gold found in the serum during or after treatment does not necessarily reflect the therapeutic or toxic effect of the preparation. However, when the gold concentration rises above 20µmol/l, signs of toxicity may occur. Sometimes the increase in gold concentration may persist long after treatment. From treatment with drugs saturated with this precious metal, the temperature sometimes rises, anxiety is felt, and intestinal activity is disturbed. Such preparations cannot be used in case of diabetes, tuberculosis, cardiovascular diseases. Other side effects of using gold salts: kidney damage, itching, rash, ulcers on the oral mucosa, tongue and pharynx. In general, renal function should be monitored regularly when using such preparations.
