How It Works in the Body

Dasatinib is like a smart missile that targets bad cells in the body, specifically those causing chronic myelogenous leukemia (CML) and acute lymphoblastic leukemia (ALL). Imagine your body as a city, where some residents (healthy cells) are harmed by bullies (cancer cells). Dasatinib locates these bullies and stops them from causing more trouble. This occurs through the inhibition of specific signals that allow these cancer cells to multiply uncontrollably. It works primarily as a BCR-ABL/SRC-family tyrosine kinase inhibitor, disrupting pathways that would otherwise help the cancer thrive.

In more technical terms, Dasatinib blocks the activity of certain enzymes that promote cancer cell survival and growth. By doing this, the treatment allows healthy cells the chance to regain control and restore balance to the body. Its effectiveness hinges on its ability to outpace the signals driving the cancerous cells to proliferate.

Clinical detail from Health Canada resources

According to Health Canada, Dasatinib is specifically effective against Philadelphia chromosome-positive (Ph+) CML and ALL, acting on the BCR-ABL fusion protein, which is a result of chromosomal translocation. This fusion protein drives the malignant transformation of the affected cells. Dasatinib’s action is not only targeted but highly effective—clinical studies indicate that many patients experience significant positive outcomes when the drug is part of their treatment regimen. Drafting from local guidelines, it’s crucial to monitor liver function and hematologic parameters during treatment.

Dosage & Administration

Standard regimens per Canadian guidelines

In Canada, Dasatinib is typically prescribed at 100 mg once daily for adult patients with chronic phase Ph+ CML. If the condition escalates to accelerated or blast phase, the dosage may rise to 140 mg daily. For paediatric patients, the recommended dose is calculated based on body surface area, generally around 60 mg/m² once daily (with a maximum of 100 mg per day).

Adjustments by patient type (with Canadian clinical notes)

dosages may vary depending on the individual's health conditions:

• Elderly: No specific adjustments are mandated but close monitoring is essential due to potential comorbidities.
• Hepatic or renal impairment: While no formal adjustment exists, caution is urged due to the possibility of altered clearance of the drug.

It's recommended to have regular assessments following Canadian clinical guidelines to ensure the effectiveness and safety of treatment with Dasatinib.

Contraindications & Side Effects
