🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a prodrug that is converted in the body to 5-fluorouracil (5-FU), which is the active anti-cancer agent. 5-FU is an antimetabolite that interferes with DNA synthesis and RNA function, leading to cell death. The conversion occurs preferentially in tumour tissues due to higher levels of certain enzymes, which may reduce systemic toxicity compared to direct 5-FU administration.

The dose may be adjusted based on the specific cancer, treatment regimen, and patient factors such as renal function and toxicity. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |

| Elderly Dosage | Elderly patients (above 65 years) may be more sensitive to the toxic effects of this medicine. Close monitoring is recommended, and dose adjustments may be necessary based on renal function and tolerability. |
| Renal Impairment | In patients with moderate renal impairment (creatinine clearance 30-50 mL/min), a dose reduction to 75% of the standard dose is recommended. This medicine is contraindicated in severe renal impairment (creatinine clearance <30 mL/min). |
