  • must not be reused
Should be worn in situations where eye, mouth, or nasal splashing is possible (i.e., during a bladder instillation of a hazardous drug)Goggles protect the eyes, but not the face, against spraying.Certified N95Powered air purifying respiratorrequired for compounding sterile and nonsterile hazardous drugsrequired for compounding sterile and nonsterile hazardous drugs
Powder-freeShown to resist permeation by hazardous drugs
  • material: polyethylene-coated polypropylene or other laminate materials
N95 offers no protection against gases and vapors.For events such as large spills when an IV bag breaks or a line disconnects and leaks, or where there is known or suspected airborne exposure to vapors or gasesDouble booties required for HD preparation areas, top layer is doffed before exiting the HD buffer room.
Inspect for visible defectsMust close in the back
(no open front)
Surgical masks do NOT provide respiratory protection from drug exposureHazardous drugs with potential to vaporize at room temperature:
• Carmustine
• Cisplatin
•Cyclophosphamide
• Etoposide
• 5-Fluorouracil
• lfosfamide
• Thiotepa
Double gloving is recommended for all activities involving hazardous drugs except for handling intact, unit-dose oral agents, when one pair of chemotherapy-tested gloves is acceptableLong sleeves with closed cuffs that are elastic or knit
When wearing double gloves, tuck the cuff of the inner glove under the gown sleeve and the cuff of the outer glove over the gown sleeve.No seams or closures that could allow hazardous drugs to pass through
During medication manipulation/compounding the outer layer should be sterileIn preparation areas gowns should be changed every 2-3 hours or immediately after a spill or splash
Change gloves every 30 minutes unless permeation testing has noted shorter time limits
  • change gloves immediately if damaged or contaminated
Gowns worn in hazardous drug handling areas must NOT be worn to other areas

Mechanism of Action:

The conjugated estrogens, equally to the normal physiological estrogen, work by agonistically binding to the estrogen receptors alpha and beta. The estrogen receptors vary in quantity and proportion according to the tissues and hence, the activity of this conjugated estrogens is very variable.2

The activity made by the conjugated estrogens is driven by the increase in the synthesis of DNA, RNA and various proteins in responsive tissues which in order will reduce the release of gonadotropin-releasing hormone, follicle-stimulating hormone and leuteinizing hormone.8

The specific mechanism of action cannot be described only in terms of total estrogenic action as the pharmacokinetic profile, the tissue specificity and the tissue metabolism is different for each component of the product.7
