Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three components: a purine or pyrimidine nucleobase (sometimes termed nitrogenous base or simply base), a pentose sugar, and a phosphate group. The substructure consisting of a nucleobase plus sugar is termed a nucleoside.
Other studies of Remicade and methotrexate indicate that the two medications together can successfully reduce symptoms of psoriasis and psoriatic arthritis, the researchers report. Studies of Humira and Enbrel in conjunction with methotrexate also revealed the combination to be more effective than the biologic alone.
Methotrexate can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often, and you may need an occasional liver biopsy. Your cancer treatments may be delayed based on the results of these tests. Store at room temperature away from moisture and heat.
