V. Drug or laboratory interactions. There is some evidence that milk thistle may inhibit CYP2C9 and CYP3A4 enzyme activity, which might theoretically increase plasma levels of dmgs metabolized by these enzymes, including amitriptyline, diazepam, clozapine, warfarin, mirtazapine, ketoconazole, and others. Drug interactions with milk thistle extract have not been reported in humans. 

Diazepam, oxazepam, and N-desmethyldiazepam have been determined under isocratic conditions (342) a somewhat more sensitive assay for diazepam and N-methyldiazepam has been reported (545). The closely related compounds, chlordiazepoxide and its N-demethyl metabolite, have also been determined (344). Analysis of the antidepressant amitriptyline, its metabolites and related drugs have been carried out using a four-component solvent (345, 346) and also aqueous acetonitrile (547).

Kay DWK, Fahy Y, Garside RF. A seven-month double-blind trial of amitriptyline and diazepam in ECT-treated depressed patients. Br J Psychiatry 1970 117 667-671. 

There has been a report of two patients with treatment-resistant PD who responded to treatment with olanzapine added to ongoing treatment with clonazepam (2 mg per day), ketazolam (30 mg per day), and venlafaxine (150 mg per day). The first patient was started on 7.5 mg at bedtime, and 2 weeks later he was much calmer and sleeping well. Olanzapine was increased to 12.5 mg per day, and venlafaxine was replaced with nefazodone up to 60 mg per day. Over the next few weeks, he improved progressively and clonazepam and ketazolam were discontinued. After 4 months, he was free from panic attacks and left his home alone. The second patient had 10 mg olanzapine daily added to ongoing treatment with 75 mg per day amitriptyline and 10 mg per day diazepam. After 2.5 months, she was being given olanzapine and had started going out on her own (126). 

Some naturally occurring neurotransmitters may be similar to drugs we use. For example, it is well known that the brain makes its own morphine (i.e., beta endorphin), and its own marijuana (i.e., anandamide). The brain may even make its own antidepressants, it own anxiolytics, and its own hallucinogens. Drugs often mimic the brain s natural neurotransmitters. Often, drugs are discovered prior to the natural neurotransmitter. Thus, we knew about morphine before the discovery of beta-endorphin marijuana before the discovery of cannabinoid receptors and anandamide the benzodiazepines diazepam (Valium) and alprazolam (Xanax) before the discovery of benzodiazepine receptors and the antidepressants amitriptyline (Elavil) and fluoxetine (Prozac) before the discovery of the serotonin transporter site.
