Abstract:
Trace levels of airborne hormones during the pharmaceutical compounding process are analyzed by air monitoring and surface sampling. This study is discussed in two parts: the first part discusses the analysis of particulates suspended in the air by using video particle counting; the second part discusses the analysis of particulates settled on the surface by using surface wipe sampling. One solution to the problem of airborne hormones is to incorporate the hormones into a vehicle like a semisolid cream with high surface tension such that there are no powders to be used during the pharmaceutical compounding process. The analytical method for this study was performed.

Types of Hormones
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
