Abstract

OBJECTIVE:

To determine the effects of food on methotrexate (MTX) absorption in patients receiving MTX for the treatment of rheumatoid arthritis (RA).

METHODS:

Standard pharmacokinetic variables were determined in patients with RA after their usual maintenance dose of MTX, under fasting conditions and after they ate a standard breakfast.

RESULTS:

No significant differences in area under the serum concentration versus time curve, maximal MTX concentration after dosing (Cmax), time to Cmax), bioavailability, urinary MTX, renal clearance of MTX, or creatinine clearance were observed between the 2 dosing conditions.

CONCLUSION:

We observed no significant effect of food on MTX absorption or bioavailability. Patients may consume MTX without regard to meals.
