My doc keep pushing SSRIs and avoiding benzos, even though he knows I would never take a SSRI... Probably gonna get an appointment with another psychiatrist as I suspect he gets profit by selling certains brands.
Does anyone have some experience with benzos, especially Clonazepam to share? Clonazepam makes me feel so good ,the anti anxiety/depression effect is really strong.
Also I found some interesting studies:
Benzodiazepines: Anxiety-Reducing Activity by Reduction of Serotonin Turnover in the Brain - PubMed
The anxiety-reducing effects of minor tranquilizers in the rat conflict test were mimicked by serotonin antagonists and by p-chlorophenylalanine, an inhibitor of serotonin synthesis; the depressant effects of the minor tranquilizers were mimicked by norepinephrine antagonists. Intraventricular injections of serotonin led to a suppression of behavior, and also antagonized the anxiety-reducing action of benzodiazeprines.
Tranquilizers may exert their anxiety-reducing effects by a reduction of serotonin activity in a behaviorally suppressive punishment system, and they may exert their depressant effects by a reduction of norepinephrine activity in a behaviorally facilitatory reward system.
Effects of Benzodiazepines on Central Serotonergic Mechanisms - PubMed
If the rat conflict test were a valid animal model of anxiety neurosis, evidence which implicates serotonin systems in the anxiety-reducing actions of benzodiazepine tranquilizers could be summarized as follows: (1) The punishment-lessening effects of benzodiazepines in the conflict test are mimicked by serotonin antagonists (methysergide, cinanserin, bromolysergic acid), serotonin synthesis inhibition (PCPA), and serotonin nerve terminal damage (5,6-dihydroxytryptamine). (2) Punishment effects may be intensified by the serotonin precursor, 5-hydroxytryptophan (in combination with a monoamine oxidase inhibitor), serotonin agonists (alpha-methyltryptamine), or intraventricular injections of serotonin itself. Intraventricularly administered serotonin also antagonizes the punishment-lessening effects of benzodiazepines. (3) Stimulation of the serotonergic cell bodies in the dorsal raphe nucleus by local application of crystalline carbachol causes intense suppression of behavior. The suppressive effects of raphe stimulation are antagonized by systemic administration of benzodiazepines. (4) In biochemical experiments, the decrease in norepinephrine turnover induced by oxazepam rapidly undergoes tolerance, whereas the decrease induced in serotonin turnover is maintained over repeated doses. These results parallel findings in the conflict test which indicate that the depressant action of oxazepam rapidly undergoes tolerance, whereas the anxiety-reducing action is maintained over repeated doses. Although central serotonin neurons are thus implicated in the therapeutic actions of benzodiazepine tranquilizers, it is quite possible that the drugs actually act indirectly to reduce serotonin activity. The concept that benzodiazepines may exert a primary action on GABA-containing neurons, which in turn regulate serotonergic transmission, was supported by preliminary psychopharmacological evidence. The GABA-antagonist picrotoxin, at doses that do not disrupt unpunished behavior, fully antagonizes the punishment-lessening effects of benzodiazepines in the conflict test.
