Miosis caused

Miosis caused by exposure to an OP vapor usually starts during exposure but may not be complete for some minutes postexposure. The degree and duration of miosis are generally dose related. However, this may not follow as a general mle. Thus, certain concentrations of anti-ChEs in contact with the eye may cau.se extreme miosis but affect accommodation only moderately (Erickson-Lamy and Grant, 1992). For example, volunteers cxpo.sed to sarin vapor had marked mio.sis but only 2.3 D of induced accommodation compared with a potential maximum of 7-10 D (Moylan-Jones and Thomas, 1973). If severe, the inability of the pupil to dilate fully in darkness may persist for a few... 

The miosis caused by oral and intravenous alfentanii was markedly increased by the short-term (1 to 3 days) and longer-term (14 days) use of ritonavir in healthy subjects. ... 

In healthy subjects the miosis caused by oral and intravenous methadone was increased by the acute use of ritonavir for 3 days but returned to below baseline after longer-term use for 14 days. It appeared that acute ritonavir inhibited, but chronic ritonavir mildly increased methadone elimination. ... 

Local irritations do not occm except by fasciculation of xmderlying muscles after percutaneous uptake or miosis caused by excessive stimulation of muscarinic receptors on the papillary sphincter muscles, resulting from ocular exposure (Sidell and Borak, 1992 Dabisch et al., 2008). However, clinical symptoms related to massive restraints in motoric and respiratory abilities require the reduction of AChE activity by more than...
