What is Gemcitabine HCl? |
|
Gemcitabine is a chemotherapy
drug that is given as a treatment for some types of
cancer. Gemcitabine is most commonly used to treat non
small cell lung cancer, pancreatic, and bladder cancer.

How does Gemcitabine HCl work?
|
|
Gemcitabine, a
pyrimidine analog, is structurally similar to cytarabine,
but has a wider spectrum of antitumour activity due to
its different cellular pharmacology and mechanism of
action. Gemcitabine is metabolized intracellularly to
two active metabolites, gemcitabine diphosphate (dFdCDP)
and gemcitabine triphosphate (dFdCTP). The cytotoxic
effects of gemcitabine are exerted through incorporation
of dFdCTP into DNA with the assistance of dFdCDP,
resulting in inhibition of DNA synthesis and induction
of apoptosis. Gemcitabine is a radiation-sensitizing
agent. It is cell-cycle phase specific (S and G1/S-phases). |

Gemcitabine HCl dosage guideline
|
|
Refer to
protocol by which patient is being treated. Numerous
dosing schedules exist and depend on disease, response
and concomitant therapy. Guidelines for dosing also
include consideration of absolute neutrophil count
(ANC). Dosage may be reduced, delayed or discontinued in
patients with bone marrow depression due to cytotoxic/radiation
therapy or in patients with other toxicities. |

Precautions of Gemcitabine HCl |
| |
|
While you are
being treated with gemcitabine, and after you stop
treatment, do not have any immunizations (vaccinations)
without your doctor's okay. Try to avoid contact with
people who have recently taken the oral polio vaccine.
Check with your doctor about this. |

|
Gemcitabine
can lower your blood counts (white blood cells, red
blood cells, platelets). Your doctor will check your
blood counts before and after each treatment to see how
it affects your blood counts. Your doctor or nurse will
give you specific instructions if your blood counts are
low. |
| |
|
Gemcitabine
can decrease your white blood cell count, especially 10
to 14 days after the drug is given. This can increase
your risk of getting an infection. Report fever of
100.5F or higher, or signs of infection such as pain in
passing your urine, coughing, and bringing up sputum. |
| |
|
Gemcitabine
can decrease the platelet count. This can increase your
risk of bleeding. DO NOT take any aspirin or aspirin containing medicines. Report unusual bruising,
or bleeding such as nosebleeds, bleeding gums when you
brush your teeth, or black, tarry stools. |
