Olabuzz-150 Tablets, Purity : 99%, Grade Standard : Medical Grade

Based on the search results, "Olabuzz-150 Tablets" is a brand name for the medication Olaparib, at a strength of 150 mg. Olaparib is a type of targeted therapy used in the treatment of certain types of cancer.

 

Mechanism of Action

 

Olaparib belongs to a class of drugs called poly(ADP-ribose) polymerase (PARP) inhibitors. Its mechanism is based on targeting a key weakness in some cancer cells.

• PARP Enzymes: PARP enzymes are a family of proteins that play a crucial role in repairing single-strand DNA breaks in cells.

• DNA Damage: Chemotherapy and other cancer treatments often work by damaging the DNA of cancer cells, leading to their death. However, cancer cells can sometimes repair this damage.

• Double Hit: Olaparib inhibits the PARP enzyme, preventing the cancer cell from repairing the single-strand breaks. This leaves the cell with a buildup of DNA damage. This is particularly effective in cancer cells that already have a defect in their ability to repair DNA, such as those with mutations in the BRCA1 or BRCA2 genes. When PARP inhibition is combined with the underlying DNA repair defect, the cancer cell can no longer repair itself, leading to its death. This is often referred to as "synthetic lethality."

 

Uses

 

Olaparib is used to treat several types of cancer that have specific genetic mutations, most notably in the BRCA1 or BRCA2 genes. Its primary uses include:

• Ovarian Cancer: It is used as a maintenance treatment for patients with advanced ovarian cancer after their tumors have shrunk or disappeared in response to initial chemotherapy. It is also used to treat recurrent ovarian cancer.

• Breast Cancer: It is used to treat HER2-negative, metastatic breast cancer in patients with a mutated BRCA gene.

• Pancreatic Cancer: It is used as a maintenance treatment for patients with metastatic pancreatic cancer who have a mutated BRCA gene and whose disease has not progressed after initial chemotherapy.

• Prostate Cancer: It is used to treat metastatic castration-resistant prostate cancer in patients with a specific type of DNA repair gene mutation.

 

Dosage and Administration

 

• Olaparib is taken orally as a tablet. The strength of 150 mg is often part of a specific dosage regimen determined by the oncologist.

• The dosage schedule is typically twice daily. It can be taken with or without food.

• It is crucial to take the medication at the same time each day and not to miss a dose.

 

Side Effects

 

Olaparib can cause several side effects. The most common ones include:

• Gastrointestinal: Nausea, vomiting, diarrhea, abdominal pain

• Hematologic: Anemia (low red blood cell count), neutropenia (low white blood cell count), thrombocytopenia (low platelet count). Regular blood tests are necessary to monitor these.

• Fatigue or Asthenia (weakness)

• Musculoskeletal: Joint or muscle pain

• Respiratory: Cough, shortness of breath

More serious, though less common, side effects can include:

• Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML): These are types of blood and bone marrow cancers that can develop as a rare but serious complication of treatment.

• Pneumonitis: Inflammation of the lungs, which can be life-threatening. Patients should report any new or worsening cough, chest pain, or difficulty breathing.

 

Important Considerations

 

• Prescription-only: Olaparib is a targeted therapy that must be prescribed and managed by an oncologist who specializes in the specific type of cancer being treated.

• Genetic Testing: The effectiveness of Olaparib is highly dependent on the presence of certain genetic mutations (e.g., in BRCA genes). Therefore, genetic testing is required before starting treatment.

• Pregnancy and Breastfeeding: Olaparib can cause harm to a developing fetus and is not recommended during pregnancy or breastfeeding. Effective contraception is required during treatment and for a period after the last dose.
