About the Study

Gemcitabine is a chemotherapeutic drug with a brand name called “Gemzar”. It treats cancers such as testicular cancer, breast cancer, ovarian cancer, non-small cell lung cancer, pancreatic cancer, and bladder cancer. Intravenous infusion is active against neoplastic growth and up regulates interferon signaling, thus inhibiting the replication of hepevirus A, the causative agent of hepatitis E. The following side effects are common (happening in extra than 30%) for patients who are taking Gemcitabine:

• Flu-like symptoms (muscle pain, fever, headache, chills, fatigue)

• Fever (inside 6-12 hours of first dose)

• Fatigue

• Nausea (mild)

• Vomiting

• Poor appetite

• Skin rash

• Low blood counts

• White and purple blood cells and platelets can also additionally quickly decrease

• This can keeps you at expanded danger level of infection, anaemia and/or bleeding

These are less common side effects of receiving gemcitabine (occurring in 10.29% of patients), such as diarrhoea, Weaknesses, Hair loss, Mouth sore, Difficulty in sleeping, Shortness of breath.

Indications and usage of Gemzar

Ovarian cancer: Gemzar in combination with carboplatin is indicated for the treatment of patients with advanced ovarian cancer who have relapsed at least 6 months after completion of platinum-based treatment.

Breast cancer: Gemzar in combination with paclitaxel is indicated for first-line treatment of patients with metastatic breast cancer who have previously failed adjuvant chemotherapy with anthracyclines, unless anthracyclines are clinically contraindicated.

Non-small cell lung cancer: The combination of Gemzar and cisplatin is indicated for first-line treatment of patients with unrespectable, locally advanced (stage IIIA or IIIB) or metastatic (stage IV) Non-Small Cell Lung Cancer (NSCLC).

Pancreatic cancer: Gemzar can be locally advanced (unrespectable stage II or stage III) or Metastatic (stage IV) adenocarcinoma of the pancreas.

Drug interactions

Gemcitabine has been combined with various chemotherapeutic compounds in the treatment of some solid tumors. Cisplatin (CDDP) is one of the most commonly used drugs in combination with gemcitabine, and in vitro studies have shown synergistic interactions between the two drugs. This synergistic effect is believed to be primarily due to increased platinum-DNA adduct formation. The synergistic effect between gemcitabine and etoposide has also been demonstrated in human ovarian and lung cancer cell lines. Recent data show that the interaction between gemcitabine and trastuzumab is concentration dependent. At lower gemcitabine concentrations, the combinations were synergistic, but at higher concentrations, the combinations were antagonistic.

Gemcitabine injection is used in combination with other medications (such as carboplatin) to treat patients with advanced ovarian cancer who have relapsed at least 6 months after treatment with other anticancer drugs. Gemcitabine injections are used with other medications (such as paclitaxel) to treat metastatic (spreading) breast cancer in patients who have received other treatments (such as anthracyclines). It is also used in combination with other medicines (such as cisplatin) to treat advanced or non-small cell lung cancer that cannot be treated surgically. A particular drug should not be used together, but it may be possible to use two different drugs together, even if interactions can occur. It is not recommended to use this medicine with the following medicines, such as Measles Virus Vaccine, Mumps Virus Vaccine, Rotavirus Vaccine, Rubella Virus Vaccine, Varicella Virus Vaccine and Zoster Vaccine.

Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, doctor may change the dose or how often you use one or both of the medicines.

• Adenovirus Vaccine

• Bacillus of Calmette and Guerin Vaccine

• Cedazuridine

• Cholera Vaccine

• Dengue Tetravalent Vaccine

• Hexaminolevulinate

• Influenza Virus Vaccine

• Poliovirus Vaccine

• Smallpox Vaccine

• Typhoid Vaccine

• Warfarin

• Yellow Fever Vaccine

Do not use certain medications before or after eating or eating certain types of foods, as interactions can occur. The use of alcohol or tobacco with certain drugs can also cause interactions. The presence of other medical problems may affect the use of this drug. Always consult the doctor if you have other medical conditions. Specifically, chickenpox (including recent exposures) or Shingles. It can increase the risk of the disease spreading to other parts of the body. Gemcitabine can reduce your body's ability to fight infections. The slow removal of the drug from the body may increase its effectiveness. Taking this medicine during pregnancy can be harmful to the fetus. Also, if the male receives a birth defect when the sexual companion becomes pregnant, it can cause a birth defect. Patients should use effective contraception during treatment with this drug and for at least 6 months after the last dose. Male patients with a female partner should use effective contraception during treatment with this drug and for at least 3 months after the last dose.
