Methotrexate is mainly used for the treatment of specific types

Methotrexate is mainly used for the treatment of specific types of cancer and along with this,
sometimes rheumatoid arthritis is also treated with this drug when all other drugs remain
unresponsive to the disease condition. Moreover, it is reported that, this drug can also be
used to treat psoriasis. The action of this drug is exerted by slowing or stopping the growth
of cancer cells and suppression of immune system of the body (Drugbank 2020).Methotrexate is mainly used for the treatment of specific types of cancer and along with this,

that drug that interferes with the action of one or more enzymes which are associated with the
process of DNA synthesis. This drug class of drugs affects the process DNA synthesis by
working as a substitute component to the original components. As a part of the antimetabolite
drugs, the functionality of methotrexate is discussed briefly (Drugbank 2020).

Functionality of Methotrexate
Hence, it can be concluded that the application of méthotrexate is associated
with the alteration of DNA synthesis process. However, it also works in various
other disease conditions such as rheumatoid arthristis , psoriasis. Its
mechanism of action is exerted by the inhibition process of the enzymes
responsible for nucleotides synthesis in the body. Therefore a few adverse
incidents are also reported by the researchers and they are mainly mouth
sores, anemia, easy bruising/bleeding, black stools, enlarged gland, unusual
pain, dry cough, muscle weakness.

drowsiness, vomiting are common. Along with this , cases of temporary hair loss, are also
reported. According to the data of Drugbank (2020), it is reported that the adverse incidents
may include mouth sores, anemia, easy bruising/bleeding, black stools, enlarged
gland, unusual pain, dry cough, muscle weakness. Moreover, cases of
infertility is also observed among males and females as well.

ConclusionWhile discussing about the mechanism of action of the drug named
methotrexate it can be stated that methotrexate enters into the tissues
and then it is converted to a methotrexate methotrexate polyglutamate
by folylpolyglutamate. The mechanism of action of methotrexate is
associated with the inhibition process of the enzymes responsible for
nucleotides synthesis in the body (Drugbank 2020). This process of
nucleotide synthesis includes synthesis of enzymes such as thymidylate
synthase, aminoimidazole caboxamide ribonucleotide transformylase
(AICART), dihydrofolate reductase and amido phosphoribosyltransferase.
Inhibition of the synthesis of this neucleotide prevents the process of cell
division. For example it can be mentioned that in case of rheumatoid
arthritis, methotrexate polyglutamates alters the action of AICART more
than methotrexate. This inhibition process leads to accumulation of
AICRT ribonucleotide and thereby causes accumulation of adenosine
triphosphate and adenosine in the extracellular space of the body. As a
result, the adenosine receptors are stimulated and anti-inflammatory
action is observed. (Inoue and Yuasa 2013)
