Abstract

Flufenamic acid (Arlef 100 - PD) is an anti-inflammatory analgesic offered for the relief of pain in rheumatic conditions. It should therefore be considered in comparison with established drugs which are used for this purpose, such as aspirin, phenylbutazone and the corticosteroids. Like mefenamic acid (Ponstan - PD) which we discussed in 1964¹ it is an anthranilic acid derivative: both drugs have similar anti-inflammatory properties but flufenamic acid is relatively more active in this respect.
