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.
Rarely, severe liver problems have occurred with the use of Remicade. These liver problems may occur from 2 weeks to more than a year after starting Remicade. Contact your doctor right away if you develop dark urine, pale stools, severe or persistent stomach pain, or yellowing of the skin or eyes.
