傾向にある。Problems to be Solved by the Invention Nonsteroidal anti-inflammatory drugs are generally classified into acidic systems and basic systems. It is said that some acidic drugs generally have an acute inflammation-suppressing and analgesic action and also have an inhibitory effect on chronic inflammation (for example, autoimmune diseases such as rheumatism). It is said that basic drugs have a relatively strong analgesic effect and also have acute inflammation suppression, but most of them cannot be expected to have an effect on chronic inflammation at present. The side effects tend to be gastrointestinal tract disorders that are considerably stronger mainly in the acidic system than in the basic system.
