Generic Ethyol, Amifostine
|
Amifostine traded under the brand name Ethyol is a chemotherapy medicinal drug which is infused into the veins before treatment for cancer begins. It is usually indicated to reduce the occurrence of modest to severe dry mouth or xerostomia symptoms that come up from radiotherapy for head and neck cancer, in addition to diminish the swelling renal toxicity that might develop from recurrent administration of cisplatin in patients with advanced cancer of the ovaries. Ethyol poses both common and serious side effects to its users.
Mechanism of Action
Ethyol (Amifostine) acts as a cytoprotective agent. It functions by getting rid of definite elements that cause impairment to the kidneys. It also cuts down some damaging impacts of radiation therapy on healthy tissues.
Dosage & Administration
The most prescribed opening dosage of Ethyol for decrease in cumulative renal toxicity with chemotherapy is 910 mg/m2 dispensed on one occasion every day as a 15-minute intravenous infusion, commencing 30 minutes before chemotherapy. The 15-minute injection is better endured in comparison to more prolonged injections. Additional decreases in infusion time periods for chemotherapy regimes have not been inquired in a systematic manner.
Affected persons must be sufficiently hydrated before Ethyol infusion and kept in a supine (lying face upward) posture at the time of infusion. Blood pressure must be supervised every 5 minutes all through the infusion, and afterward as medically suggested.
For decrease in moderate to severe dry mouth symptoms from radiation, the prescribed dosage of Ethyol (Amifostine) is 200 mg/m2 dispensed one time on a daily basis as a 3-minute intravenous infusion, beginning 15-30 minutes ahead of normal fraction radiotherapy (1.8-2.0 Gy, the SI unit of energy soaked up from ionizing radiation).
Patients must be satisfactorily hydrated before Ethyol injection. Blood pressure must be checked, in any case, before and straightaway after the infusion and after that, as clinically pointed out.
Drug Supply
Ethyol (Amifostine) for infusion is provided as a germ-free freeze-dried powder in 10 mL single-use vials. Every vial for a solitary use comprises 500 mg of Amifostine on the anhydrous (without water) basis.
