描述 | Prazosin Hydrochloride, an a1-adrenoceptor blocker, has shown some promise in treating chronic PTSD (Posttraumatic stress disorder). Treatment of PTSD with prazosin is usually initiated at a dose of 1 mg, with monitoring for hypotension after the first dose. The dose is then gradually increased to maintenance levels of 2-6 mg at night[3]. Prazosin has been shown to be effective in the treatment of PTSD trauma-related nightmares, with low side effect profile and abilities to improve both sleep and reduce trauma nightmares[4]. Prazosin is extensively metabolised by the liver and has high first-pass metabolism and low oral bioavailability. Oral bioavailability of prazosin ranges from 43.5 to 69.3% (mean 56.9%). Prazosin is highly (92 to 97%) bound to human plasma proteins (albumin and alpha 1-acid glycoprotein) and the extent of binding is independent of the plasma concentration of the drug in the range of 20 to 150 ng/mL[5]. |
