L. iris, rainbow) Tennant discovered iridium in 1803 in the residue left when crude platinum is dissolved by aqua regia. The name iridium is appropriate because its salts are highly colored. [Pg.138]

Seecof and Tennant 1987), the most common feelings associated with the rush were pleasure, relaxation, and satisfaction. Although at one time the rush was classically reported to be similar to a sexual orgasm, in a study of the phenomenon such a feeling was reported in only 18% of men and 10% of women (Seecof and Tennant 1987). [Pg.63]

Methadone is a p receptor agonist with special properties that make it particularly useful as a maintenance agent. Rehably absorbed orally, it does not reach peak concentration until about 4 hours after administration and maintains a large extravascular reservoir (Kreek 1979). These properties minimize acute euphoric effects. The reservoir results in a plasma half-life of 1—2 days, so there are usually no rapid blood level drops that could lead to withdrawal syndromes between daily doses. Effective blood levels are in the range of 200-500 ng/mL. Trough levels of 400 ng/mL are considered optimal (Payte and Khouri 1993). There is wide variability among individuals in blood levels with identical doses (Kreek 1979), and some have inadequate levels even with doses as high as 200 mg/day (Tennant 1987 Tenore 2003). [Pg.76]

LAAM (L-a-acetylmethadol or levomethadyl acetate) is a full agonist at the i opioid receptor with pharmacologic properties similar to those of methadone. A number of studies have demonstrated that treatment with LAAM results in reduction of opioid use and beneficial effects comparable to those achieved with methadone (Ling et al. 1978 Tennant et al. 1986 Zangwell et al. 1986). However, retention rates are higher in patients who take methadone doses of 80—100 mg/day. [Pg.80]

LAAM usually has been prescribed in doses of 20—140 mg (Ling et al. 1978 Tennant et al. 1986). The typical Monday-Wednesday-Friday dosing schedule is 100 mg—100 mg—140 mg. The maximum recommended doses are 140 mg—140 mg—140 mg or 130 mg—130 mg—180 mg (thrice-weekly schedule) or 140 mg every other day. For some patients LAAM holds better than methadone. There is evidence that LAAM may be particularly helpful for patients who do not respond to high-dose methadone because of low plasma levels (Tennant 1988). Others patients prefer LAAM to methadone because they can attend the clinic less often (Tennant et al. 1986 Trueblood et al. 1978). However, a few experience nervousness and stimulation while taking this drug. [Pg.80]

We have viewed these withdrawal effects on behavior as evidence of behavioral dependence on PCP. Behavioral signs have also been reported in human users of PCP during withdrawal (Tennant et al. 1981) however, these instances appear to be relatively rare. Nonetheless, the relative ease with which a dependence phenomenon can be produced in monkeys suggests that PCP has a potential for producing dependence in PCP users, particularly those who use the drug very frequently. Behavioral sequelae seen in chronic PCP abusers might be examined as possible manifestations of dependence as well as of cumulative toxicity. [Pg.170]
