Introduction

Docetor 80 mg (Docetaxel) Injection stands as a cornerstone in modern cancer therapy, offering healthcare professionals a powerful tool in the battle against various malignancies. This high-concentration formulation delivers potent antineoplastic action through its unique mechanism targeting cellular microtubules. Manufactured by the renowned Eskayef Pharmaceuticals Ltd. and distributed globally by Orio Pharma, Docetor 80 mg represents the gold standard in quality and efficacy for oncology treatment protocols worldwide. With its proven clinical effectiveness across multiple cancer types, this premium injectable medication continues to be an essential component in comprehensive cancer management strategies.

Therapeutic Applications

Docetor 80 mg demonstrates remarkable versatility in treating several forms of cancer, making it indispensable in oncology practice:

Breast Cancer (BC): Docetor functions effectively as a single agent for locally advanced or metastatic breast cancer in patients who have experienced chemotherapy failure. Additionally, when combined with doxorubicin and cyclophosphamide, it serves as an adjuvant treatment for operable node-positive breast cancer, significantly improving long-term outcomes.

Non-small Cell Lung Cancer (NSCLC): For patients with locally advanced or metastatic NSCLC who have experienced platinum therapy failure, Docetor offers an effective single-agent treatment option. In combination with cisplatin, it provides a powerful regimen for unresectable, locally advanced, or metastatic untreated NSCLC cases.

Castration-Resistant Prostate Cancer (CRPC): When administered alongside prednisone, Docetor delivers targeted therapy for metastatic castration-resistant prostate cancer, addressing a challenging condition with historically limited treatment options.

Gastric Adenocarcinoma (GC): In combination with cisplatin and fluorouracil, Docetor creates an effective treatment protocol for untreated, advanced gastric adenocarcinoma, including cancers affecting the gastroesophageal junction.

Squamous Cell Carcinoma of the Head and Neck (SCCHN): As part of an induction treatment regimen with cisplatin and fluorouracil, Docetor effectively targets locally advanced SCCHN, providing patients with improved therapeutic outcomes.

Advanced Pharmacological Mechanism

The exceptional effectiveness of Docetor 80 mg stems from its sophisticated mechanism of action within cancer cells. As a microtubule inhibitor, docetaxel disrupts the microtubular network essential for vital mitotic and interphase cellular functions. This disruption occurs through a dual mechanism:

Docetor actively promotes the assembly of tubulin into stable microtubules while simultaneously inhibiting their disassembly. By binding to free tubulin, the medication decreases the critical intracellular concentration of this protein. This promoted polymerization leads to the production of microtubule bundles without normal function and stabilizes these structures, effectively inhibiting mitosis in cancer cells.

Unlike other spindle poisons, Docetor’s binding to microtubules does not alter the number of protofilaments in the bound microtubules, representing a unique mechanism of action in cancer therapy. Laboratory studies have confirmed Docetor’s cytotoxic properties against various murine and human tumor cell lines, as well as freshly excised human tumor cells in clonogenic assays.

Notably, Docetor has demonstrated effectiveness against cell lines that overexpress p-glycoprotein, which is encoded by the multidrug resistant gene – a significant advantage in treating resistant cancer types that have traditionally shown poor response to conventional chemotherapy.

Precise Dosage and Administration Guidelines

For optimal therapeutic outcomes, Docetor 80 mg must be administered in a facility equipped to manage potential complications such as anaphylaxis. The injection is delivered intravenously over one hour every three weeks. Important administration notes include avoiding PVC equipment and using only a 21-gauge needle for withdrawal from the vial.

Dosage recommendations vary by cancer type:

• Breast Cancer (locally advanced or metastatic): 60-100 mg/m² as a single agent
• Breast Cancer (adjuvant): 75 mg/m² administered one hour after doxorubicin 50 mg/m² and cyclophosphamide 500 mg/m² every three weeks for six cycles
• NSCLC (after platinum therapy failure): 75 mg/m² as a single agent
• NSCLC (chemotherapy-naive): 75 mg/m² followed by cisplatin 75 mg/m²
• Hormone-Refractory Prostate Cancer: 75 mg/m² with 5 mg prednisone twice daily continuously
• Gastric Cancer: 75 mg/m² followed by cisplatin 75 mg/m² (day 1 only) and fluorouracil 750 mg/m² per day as a 24-hour IV (days 1-5)
• SCCHN: Two protocol options are available, involving different dosages of cisplatin and fluorouracil for either 3 or 4 cycles

All patients should receive oral corticosteroid premedication before administration, with dosage adjustments made as clinically indicated based on individual patient response and tolerance.

Safety Profile and Considerations

Healthcare providers should be aware of Docetor’s comprehensive safety profile to ensure optimal patient outcomes:

Contraindications: Docetor 80 mg should not be administered to patients with neutrophil counts below 1,500 cells/mm³ or those with a history of severe hypersensitivity reactions to docetaxel or polysorbate 80, as severe reactions including anaphylaxis have been reported.

Drug Interactions: As a CYP3A4 substrate, Docetor’s metabolism may be modified by compounds that induce, inhibit, or are metabolized by cytochrome P450 3A4, necessitating careful medication review before treatment initiation.

Common Side Effects: Patients may experience infections, neutropenia, anemia, febrile neutropenia, hypersensitivity, thrombocytopenia, neuropathy, dysgeusia, dyspnea, constipation, anorexia, nail disorders, fluid retention, asthenia, pain, nausea, diarrhea, vomiting, mucositis, alopecia, skin reactions, and myalgia. Incidence varies by indication and patient factors.

Special Precautions: Docetor administration requires supervision by physicians experienced with antineoplastic agents. Higher risks exist for patients with hepatic impairment, including toxic death and fatal gastrointestinal hemorrhage. Healthcare providers should monitor for enterocolitis, severe hypersensitivity reactions, and treatment-related acute myeloid leukemia.

Overdose Management: In case of overdose, patients should be kept in specialized units with close monitoring of vital functions. Primary anticipated complications include bone marrow suppression, peripheral neurotoxicity, and mucositis. Therapeutic G-CSF should be administered as soon as possible after overdose discovery, along with appropriate symptomatic measures.

Pregnancy, Lactation, and Storage

Based on animal studies and its mechanism of action, Docetor can cause fetal harm when administered during pregnancy. No information is available regarding its presence in human milk or effects on breastfeeding children. Healthcare providers should carefully weigh benefits against risks when considering treatment for pregnant or nursing women.

To maintain product integrity, store Docetor 80 mg between 2°C and 25°C, protected from light. While freezing does not adversely affect the product, proper storage ensures maximum efficacy throughout its shelf life.
