GLIADEL vs URACIL MUSTARD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GLIADEL (carmustine implant) is a biodegradable wafer that delivers carmustine, a nitrosourea alkylating agent, directly into the tumor resection cavity. Carmustine alkylates DNA and RNA, leading to cross-linking and inhibition of DNA replication, ultimately causing cell death. It is cell cycle phase nonspecific.
Uracil mustard is a nitrogen mustard alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription, leading to cell death.
Gliadel (carmustine) implant is administered intraoperatively as 8 wafers, each containing 7.7 mg carmustine, placed in the resection cavity after tumor debulking. Maximum dose is 61.6 mg (8 wafers).
1 mg orally daily for 3 weeks, then 1 mg daily every 4 weeks, or 0.15 mg/kg orally once weekly.

Terminal elimination half-life is approximately 1.3 hours for the active dianhydrogalactitol metabolite. Clinical context: short half-life supports local interstitial delivery with minimal systemic accumulation.
Terminal half-life approximately 6–8 hours in patients with normal renal function; may be prolonged with renal impairment
Primarily renal (60-70% as unchanged drug and metabolites) and biliary/fecal (15-20%). Approximately 10-15% is eliminated via exhaled air as CO2.
Primarily renal (56-80% as unchanged drug and metabolites); minor fecal (10%)
