回复1楼 Tina:求助一款抗抑郁的药
抑郁症是一个很重要的话题,对于目前在临床上应用的大部分抗抑郁症药物来说,首先如果我们要用雷沙吉兰的话,抗抑郁症药物就必须限制,包括SSRI,SSRA,NaSSA等等,特别是SSRI(选择性5-HT再摄取抑制剂),和女性乳癌有相当大的关联,必须小心应用。
而比较安全且有效的方法,可以考虑摄取SAMe(S-腺苷蛋氨酸)来治疗抑郁症包括重度抑郁症(但不适用于躁狂症),有几大功能,包括抗抑郁症,还有适用于帕金森症的增加多巴胺合成,另外对骨关节炎的好处。在欧洲自70年代开始已经用于抑郁症的治疗,副作用是非常小的。
我把国际上对SAMe的一些研究附了一点,有兴趣的可以再深入。
我的推荐剂量是每天800mg至1600mg,分二次服用,三周为一个疗程。

Rapidity of onset of the antidepressant effect of parenteral
S-adenosyl-L-methionine.

A possible method of reducing the delay in antidepressant response is to use
S-adenosyl-L-methionine (SAMe), a naturally occurring compound that appears to
have a rapid onset of effect in the treatment of depression. In this open,
multicenter study, 195 patients were given 400 mg of SAMe, administered
parenterally, for 15 days. Depressive symptoms remitted after both 7 and 15
days of treatment with SAMe, and no serious adverse events were reported.
Further studies with a double-blind design are needed to confirm this
preliminary indication that SAMe is a relatively safe and fast-acting
antidepressant.

S-adenosyl-l-methionine (SAMe) as antidepressant: meta-analysis of clinical
studies.

INTRODUCTION--S-adenosyl-l-methionine (SAMe) is a naturally-occurring substance
which is a major source of methyl groups in the brain. MATERIAL AND METHODS--We
conducted a meta-analysis of the studies on SAMe to assess the efficacy of this
compound in the treatment of depression compared with placebo and standard
tricyclic antidepressants. RESULTS--Our meta-analysis showed a greater response
rate with SAMe when compared with placebo, with a global effect size ranging
from 17% to 38% depending on the definition of response, and an antidepressant
effect comparable with that of standard tricyclic antidepressants.
CONCLUSION--The efficacy of SAMe in treating depressive syndromes and disorders
is superior with that of placebo and comparable to that of standard tricyclic
antidepressants. Since SAMe is a naturally occurring compound with relatively
few side-effects, it is a potentially important treatment for depression.

The clinical potential of ademetionine (S-adenosylmethionine) in neurological
disorders.

This review focuses on the biochemical and clinical aspects of methylation in
neuropsychiatric disorders and the clinical potential of their treatment with
ademetionine (S-adenosylmethionine; SAMe). SAMe is required in numerous
transmethylation reactions involving nucleic acids, proteins, phospholipids,
amines and other neurotransmitters. The synthesis of SAMe is intimately linked
with folate and vitamin B12 (cyanocobalamin) metabolism, and deficiencies of
both these vitamins have been found to reduce CNS SAMe concentrations. Both
folate and vitamin B12 deficiency may cause similar neurological and
psychiatric disturbances including depression, dementia, myelopathy and
peripheral neuropathy. SAMe has a variety of pharmacological effects in the
CNS, especially on monoamine neurotransmitter metabolism and receptor systems.
SAMe has antidepressant properties, and preliminary studies indicate that it
may improve cognitive function in patients with dementia. Treatment with methyl
donors (betaine, methionine and SAMe) is associated with remyelination in
patients with inborn errors of folate and C-1 (one-carbon) metabolism. These
studies support a current theory that impaired methylation may occur by
different mechanisms in several neurological and psychiatric disorders.

S-adenosylmethionine blood levels in major depression: changes with drug
treatment.
Bell KM, Potkin SG, Carreon D, Plon L
University of California, Irvine Medical Center, Orange 92668.
INTRODUCTION--The relationship between plasma levels of S-adenosylmethionine
(SAMe), an endogenous methyl donor, and clinical response were studied in
patients with a DSM-III-R diagnosis of major depression. MATERIAL AND
METHODS--A double-blind randomized protocol comparing oral SAMe with oral
desipramine, involving a total of 26 patients, was employed. RESULTS--At the
end of the 4-week trial, 62% of the patients treated with SAMe and 50% of the
patients treated with desipramine had significantly improved. Regardless of the
type of treatment, patients with a 50% decrease in their Hamilton Depression
Scale (HAM-D) score showed a significant increase in plasma SAMe concentration.
CONCLUSION--The significant correlation between plasma SAMe levels and the
degree of clinical improvement in depressed patients regardless of the type of
treatment suggests that SAMe may play an important role in regulating mood.

S-adenosylmethionine levels in psychiatric and neurological disorders: a
review.
Bottiglieri T, Hyland K
Metabolic Disease Center, Baylor Research Institute, Dallas, TX 75226.
INTRODUCTION--S-adenosylmethionine (SAMe) is an important methyl donor in over
35 methylation reactions involving DNA, proteins, phospholipids and catechol-
and indole- amines. MATERIAL AND METHODS--This article reviews the studies that
have examined brain and blood levels of SAMe in several psychological,
neurological and metabolic disorders. RESULTS--Although studies have found no
consistent changes in whole blood SAMe levels in psychiatric patients, other
investigators have found low cerebrospinal fluid (CSF) SAMe levels in patients
with neurological disorders such as Alzheimer’s dementia, subacute combined
degeneration of the spinal cord (SACD), and HIV-related neuropathies, as well
as in patients with metabolic disorders such as 5, 10-CH2-H4 folate reductase
deficiency. CONCLUSION--Intravenous or oral administration of SAMe thus
represents a possible treatment for these neurological and metabolic disorders
