Leukemia commonly used chemotherapy drugs
Western medicine is the main drug treatment of leukemia induced by a
variety of leukemia cell differentiation and apoptosis of chemical
drugs, most have a specific effect, is the oral administration of
traditional Chinese medicine can not be replaced. With chemotherapy for
cancer, including leukemia, only 60 in the coming year history. In
1943, the first nitrogen mustard for the treatment of lymphoma, while
the breakthrough success of the treatment of leukemia was found in
Ara-C and methotrexate. Currently used for treatment of leukemia has
been more than 30 kinds of chemotherapy drugs, including commonly used
are:
1, the drugs interfere with nucleic acid biosynthesis. Such drugs
known as anti-metabolite. They, through their specific interference
with cell division and reproduction of leukemia, specific varieties
are:
Cytarabine (ara-c), injection. Used for a variety of acute
leukemia, meningeal leukemia, is the effect of chemotherapy in the best
commonly used species.
Cyclocytidine (cc). Injection. Indications with Ara-C the same.
Methotrexate (mtx), commonly used injection, there are tablets.
Children, the treatment of lymphocytic leukemia, the most important
drug, but for all of intrathecal chemotherapy drug of choice.
Hydroxyurea (hu), for oral administration. Chronic myeloid leukemia in the main treatment drugs.
6 - mercaptopurine (6-mp, music Weijining). Is the treatment of
oral maintenance therapy of acute lymphoblastic leukemia drug. Is also
used in CML.
Thioguanine (6-tg) oral treatment of acute leukemia or CML.
2, a direct impact on cancer cell dna structure and function of drugs.Some varieties of antibiotics. Its role is to make cancer cells
dna strand breaks, base pairing the wrong code, functions such as the
failure. Varieties include:
Busulfan (white blood Fu, Maryland, mac waves, bu). Chronic myeloid leukemia oral treatment drug, is now rarely used.
Etoposide (vp-16) Podophyllotoxin derivatives, injection. Is an important treatment of refractory leukemia drug.
Vermeer (Nigeria for Vm, vm-26). New - on behalf of the
podophyllotoxin derivatives used for treatment of children with acute
lymphocytic.
Mitomycin C (mmc) injection. For CML and lymphoma.
Chlorambucil (tumor can-ning, cbl, cb1348), oral. Is mainly used for chronic lymphocytic leukemia and hairy
Cell leukemia.
L-phenylalanine nitrogen mustard (cbl, melphalan, L-melting sarcoma Su), oral. Is mainly used for CLL, or CML.
Bian nitrogen mustard (diclofenac sodium has nitrosourea, bcnu) injection. Is mainly used for meningeal leukemia and CLL.
Cyclophosphamide (ctx) with injections and tablets. For a variety
of leukemia, and other anti-leukemia chemotherapy composed of different
chemotherapy regimens.
Cyclohexyl nitrosourea (ccnu). Oral treatment of meningeal leukemia and CLL.
3, interference rna transcription process and prevent the synthesis of drugs.
Daunorubicin (dnr). Injection. An anthracycline antibiotic, could
be embedded in dna base pairs between the inhibition rna synthesis,
prevents dna replication, and showed cytotoxicity. Is the treatment of
acute leukemia of essential medicines, the effects of acute lymphocytic
better, but also as other chemotherapy-resistant second-line
chemotherapy drugs,
Doxorubicin (demethylation daunorubicin, 1da, adm), injection. In
recent years with the DNR are both listed on the mechanism but the
effects are better with the treatment of acute leukemia drug, has been
the first choice as a treatment for acute lymphocytic drugs, but the
price higher.
Adriamycin (adr) injection. Pharmacological role and indications
with the DNR, but the relatively large gastrointestinal adverse
reactions.
Epirubicin (ep1) Adriamycin isomers, efficacy and doxorubicin are
equally divided, in particular, cardiac toxicity low toxicity.
Pirarubicin (THP, thp-adm) 1979 and a half years synthetic
anthracycline anticancer drug, structure, style and adriamycin similar
for leukemia and other cancers.
Aclacinomycin (acm-a, acl, acr). Anthracycline anti-cancer drugs, efficacy and adriamycin approximation.
4, inhibit protein synthesis and function of drugs.
Vincristine (vcr), injection. Vinca plant extract active
ingredients, for the tubulin inhibitors. In inhibiting microtubule
polymerization, so that spindle can not form, cancer cells stop
dividing, is an effective treatment of acute and chronic leukemia drug,
commonly used for children-ALL. Is also used in malignant lymphoma and
other cancer treatment.
Vindesine (Vindesine, VDS, vds), for the semi-synthetic
derivatives of vinblastine, vincristine indications and similar but low
toxicity.
Homoharringtonine base (hhar). To Cephalotaxus alkaloids extracted
from plants, in order to interfere with the formation of nucleoprotein,
inhibit cell division in drugs. The treatment of common acute and
chronic leukemia drug.
l-L-L-asparaginase (asp), injection. Affecting the amino acid
supply of the drugs. -ALL cell's own synthesis of l-asparaginase can
not take lessons from the cells outside. The drug can asparagine
hydrolysis, so that cancer cells can not survive lack of nutrition. Is
mainly used for emergency shower, is an important treatment of children
with acute lymphocytic drugs. Its biggest drawback is that will trigger
diabetes.
5, other.
All-trans retinoic acid (atrt). 1986, Ruijin Hospital, Shanghai
Institute of Hematology and the first to discover its efficacy m3 good
governance, is to induce cell differentiation, inhibit proliferation of
leukemic cells. After the popularization and application, where a large
number of patients with m3.
Arsenic trioxide (as203). This drug the seventies of the twentieth
century scholars, beginning with China's traditional Chinese medicine
treatment of leukemia in the screening of drugs for the treatment of m3
out of chemical drugs, can induce cell differentiation and apoptosis in
a double role. Ineffective treatment of RA cases may still be
effective, it is now made of injection has become a common drug
treatment m3.
Gleevec (stl571, imatinib mesylate). Treatment of CML the latest
chemical drugs. First used in 1998. Its role is to block protein
synthesis in some cancer cells, thus inhibiting their replication and
proliferation-resistant mechanisms, adverse reactions is low, good
curative effect, remission rate is higher than any previous one drug
(0.4g for at least 12 weeks on a course of treatment) . On the
accelerated phase and blastic phase of the case are also valid (Japan
0.6g), was considered the best current treatment of CML drugs. China in
recent years is already in use and to achieve the desired clinical
effect. CML 3 cr rates were hematological 95-34-7%; ph chromosome
negative conversion rates were 41-17-7%. But the long-term efficacy and
the pros and cons are still to be seen. A recent report, this product
may have toxic effects on the heart. The goods and interferon,
daunorubicin, cytarabine, vincristine, etoposide, and so there is
synergy when combined with reduction. On the contrary with
dexamethasone, topotecan, methotrexate, hydroxyurea and so there is
antagonism. ph chromosome-positive leukemia, the other treatment may
make the FDA. However, the drug is expensive, Japan and cost a thousand
dollars, non-ordinary patient can bear.
Mitoxantrone (m1t, nvt, dhad). This product is synthetic
anthracycline anticancer drug doxorubicin similar structure and, for
leukemia and other cancers.
AMSA (amsa), for a variety of acute leukemia.
Topotecan (tpt) to topoisomerase inhibitors, may be co-vp-16, ctx governance cml CML.
Glucocorticoids. The main species used for the treatment of
leukemia is prednisone (preed) and dexamethasone (dex). The primary
role of its anti-leukemic lymphocytes mechanism is dissolved, so that
lymphoid tissue atrophy,
Interferon. Interferon is a substance such as human cells after
stimulation by the virus released by the immune substances that the
present commodity interferon are mostly prepared by genetic
engineering, dna recombinant products. There are many of its
pharmacological effects, including inhibiting the virus reproduction,
immune regulation and anti-tumor effect, to prevent cancer cell growth,
promote nk and macrophage cell functions. Is mainly used in the
treatment of hematologic malignancies in CML (to prevent the
acceleration of CML have a good effect, but a continuous medication
time normally not more than 1 year, but also prone to adverse reactions
and complications, it can not meet the requirements of the long-term
anti-CML) , hairy cell leukemia, non-Hodgkin's lymphoma, multiple
myeloma.
Cyclosporin a (csa). To act on the t-lymphocyte powerful
immunosuppressant. This product is no significant inhibitory effect on
the bone marrow. Is mainly used for organ or tissue transplantation
graft-versus-host reaction; also used in some autoimmune diseases and
refractory leukemia. There are oral agents and injections.
Calcium folinate (sub-acid, folinic CF). This product is no
anti-tumor effect, mainly for high-dose methotrexate infusion to
rescue; and fluorouracil combination can enhance the therapeutic effect
of the latter.
