EA-3834 is a potent anticholinergic deliriant drug with a fairly long duration of action, related to the chemical warfare agent 3-Quinuclidinyl benzilate (QNB). It was developed under contract to Edgewood Arsenal during the 1960s as part of the US military chemical weapons program, during research to improve upon the properties of earlier agents such as QNB.
EA-3834 has a potency and central to peripheral effects ratio only slightly less than that of related compounds such as EA-3443, and is faster acting and shorter lasting, although not as much as other compounds such as 302196.
EA-3834 appears to cause renal problems, among them, microhematuria.
Another version [of BZ], called EA 3834, appeared to cause microscopic hematuria—tiny amounts of blood in urine—and other renal problems.
