Dosing
Rheumatoid Arthritis, Degenerative polyarthritis, Ankylosing spondylitis 750 mg or 1,000 mg once daily; may be increased to 1,500 mg once daily for limited periods when a higher level of anti-inflammatory/analgesic activity is required.

Rheumatoid Arthritis 7.5 mg SC once weekly; adjust dose gradually; doses greater than 20 mg/week associated with significant increase in serious toxic reactions in adults.
Juvenile polyarthritis 10 mg/m2 SC once weekly; adjust dose gradually.
Psoriasis 10 to 25 mg SC once weekly; do not exceed 30 mg/week; reduce to lowest effective dose once optimal response is achieved.

Pharmacology
Naproxen is an NSAID with analgesic, anti-inflammatory, and antipyretic properties that acts by inhibiting cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis in peripheral tissues.
Methotrexate inhibits dihydrofolic acid reductase, preventing reduction of dihydrofolates to tetrahydrofolates and thereby interfering with DNA synthesis, repair, and cellular replication; in RA the mechanism is unknown but may affect immune function, and in psoriasis it exploits the markedly increased rate of epithelial cell proliferation.
