methadone and Hypotension

methadone has been researched along with Hypotension in 7 studies

Methadone: A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)
methadone : A racemate comprising equimolar amounts of dextromethadone and levomethadone. It is a opioid analgesic which is used as a painkiller and as a substitute for heroin in the treatment of heroin addiction.
6-(dimethylamino)-4,4-diphenylheptan-3-one : A ketone that is heptan-3-one substituted by a dimethylamino group at position 6 and two phenyl groups at position 4.

Hypotension: Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.

( Drenger, B; Gozal, Y; Matot, I; Shauli, A; Weissman, C, 2004)
"Significant differences in levels of withdrawal symptoms were found on days 11, 13-15 and 17-20, symptoms resolving most rapidly in the 5-day lofexidine treatment group, whilst withdrawal responses in the 10-day lofexidine treatment group were intermediate between the 5-day lofexidine and standard methadone treatment conditions."2.69Accelerated lofexidine treatment regimen compared with conventional lofexidine and methadone treatment for in-patient opiate detoxification.
