By targeting cancers associated with genetic vulnerabilities, Olaparix 150 mg offers a tailored therapeutic approach for patients.
Therapeutic Class
Olaparix 150 mg belongs to the PARP (Poly ADP-Ribose Polymerase) Inhibitor class of medications. PARP inhibitors are a relatively new group of anticancer agents that specifically target DNA repair mechanisms in cancer cells. This therapeutic class provides a focused approach to treating cancers associated with genetic mutations like BRCA1 and BRCA2.
Pharmacology
Olaparix 150 mg exerts its effects by inhibiting the PARP enzyme. PARP plays a critical role in repairing single-strand breaks in DNA. By blocking this enzyme, Olaparib disrupts the cancer cells’ ability to repair their DNA, especially in cells already compromised by BRCA mutations. This leads to:
- Accumulation of DNA damage in cancer cells.
- Cell death (apoptosis) due to irreparable DNA damage.
- Selective targeting of cancer cells, minimizing effects on normal cells.
This pharmacological approach makes Olaparix particularly effective in cancers with defective DNA repair pathways.
Dosage of Olaparix 150 MG
The recommended dosage of Olaparix 150 mg varies based on the type of cancer being treated. Typically, it involves:
- Standard Dosage: 300 mg per day, taken as two 150 mg tablets twice daily.
- Adjusted Dosage: Based on tolerability and patient-specific factors such as liver or kidney function.

Drug Classes
Olaparix 150 mg belongs to the PARP (Poly ADP-Ribose Polymerase) Inhibitor drug class. PARP inhibitors are an innovative group of anticancer agents targeting DNA repair mechanisms in cancer cells. These medications exploit the inability of cancer cells with genetic mutations like BRCA1 or BRCA2 to repair DNA damage effectively. By inhibiting PARP enzymes, Olaparix prevents the repair of single-strand DNA breaks, causing accumulation of DNA damage and ultimately leading to cancer cell death. This mechanism selectively targets cancer cells while sparing normal cells, making it a cornerstone in precision oncology for cancers like ovarian, breast, pancreatic, and prostate with specific genetic vulnerabilities.
Mechanism of Action
Olaparix 150 mg works by inhibiting the PARP (Poly ADP-Ribose Polymerase) enzyme, crucial for repairing single-strand DNA breaks. Normally, PARP facilitates DNA repair, ensuring cell survival. In cancer cells with BRCA1 or BRCA2 mutations, an alternative DNA repair pathway, homologous recombination (HR), is defective. By blocking PARP, Olaparix prevents repair of DNA damage, leading to the accumulation of single-strand breaks that progress to double-strand breaks during cell replication. Without functional HR repair, these double-strand breaks become irreparable, triggering genomic instability and apoptosis (cell death). This mechanism selectively targets cancer cells with defective DNA repair pathways, minimizing harm to normal, healthy cells.
Pregnancy
Olaparix 150 mg is contraindicated during pregnancy due to its potential to harm the developing fetus. Preclinical studies indicate risks such as embryotoxicity and teratogenicity (causing developmental abnormalities). Women of childbearing potential must use effective contraception during treatment and for at least six months after the last dose to avoid pregnancy. If pregnancy occurs, treatment should be discontinued immediately, and the patient must consult a healthcare provider. Olaparix can cross the placenta, leading to fetal DNA damage due to its PARP inhibition mechanism, which disrupts cell replication. For safety, planning pregnancy while on Olaparix requires thorough discussion with a doctor to weigh risks and benefits.
Overdose Effects of Olaparix 150 mg
An overdose of Olaparix 150 mg can lead to significant toxicities and adverse effects due to excessive PARP inhibition. Symptoms may include severe nausea, vomiting, extreme fatigue, and dizziness. Overdose can also result in bone marrow suppression, leading to complications such as anemia, neutropenia, and an increased risk of infections or bleeding. Other effects might include gastrointestinal discomfort and worsening of pre-existing side effects. If an overdose is suspected, seek immediate medical attention. Treatment is primarily supportive and focuses on managing symptoms, including hydration, monitoring blood counts, and addressing complications. Dialysis is unlikely to remove Olaparix effectively due to its high protein binding.
Uses of Olaparix 150 MG
Olaparix 150 mg is used for the treatment of specific cancers, particularly those with BRCA mutations or other homologous recombination repair (HRR) gene mutations. It is commonly prescribed for advanced ovarian cancer, especially in patients who have responded to platinum-based chemotherapy and require maintenance therapy. Olaparix is also effective for HER2-negative breast cancer with BRCA mutations, metastatic pancreatic cancer, and metastatic castration-resistant prostate cancer (mCRPC) with HRR mutations. By targeting DNA repair mechanisms in cancer cells with these genetic defects, Olaparix offers a personalized treatment approach, improving outcomes for patients with these specific cancer types.
Alternative Medicine to Olaparix 150 mg
Olanib 150 mg, a PARP inhibitor, is an alternative to Olaparix 150 mg. Olanib, like Olaparix, targets cancer cells’ DNA repair processes, namely those with BRCA gene abnormalities. It is used to treat cancers such as ovarian, breast, pancreatic, and prostate cancers that have BRCA or HRR gene abnormalities. The generic name of this medicine is Olaparib. Olanib inhibits the PARP enzyme, preventing cancer cells from repairing damaged DNA and causing their death. This method is advantageous for patients with genetically sensitive malignancies because it allows for precise treatment while minimizing damage to good cells. Always consult a healthcare provider about the proper dosage and any potential interactions or side effects.
