DESCRIPTION Celexa (citalopram HBr) is an orally administered selective serotonin reuptake inhibitor (SSRI) TM with a chemical structure unrelated to that of other SSRI’s or of tricyclic, tetracyclic, or other available antidepressant agents. Citalopram HBr is a racemic bicyclic phthalane derivative designated (±)-1-(3-dimethylaminopropyl)-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran-5-carbonitr...

Depression is a common illness worldwide, with an estimated 350 million people affected. Projections even indicate that by 2020 it will be ranked second cause of disability worldwide. There are effective treatments for depression but it is estimated that one third of depressed patients do not respond adequately to conventional antidepressant drugs. Moreover, among responders, one of the main li...

Monoamine oxidase inhibitors (MAOIs) have a long and storied history as some of the earliest antidepressants created. The efficacy of these medications led to the development of the monoamine hypothesis of depression and the development of subsequent antidepressant medications. Despite their known efficacy, MAOIs have fallen out of favor in clinical practice, giving way to newer agents with mor...

Acetylhydrazine, a metabolite of isoniazid, a widely used antituberculosis drug, and isopropylhydrazine, a metabolite of iproniazid, an antidepressant removed from clinical use because of high incidence of liver injury, were oxidized by cytochrome P-450 enzymes in human and rat liver microsomes to highly reactive acylating and alkylating agents. Covalent binding of these metabolites to liver ma...

mirtazapine is a new antidepressant that can increase noradrenergic and serotonergic neurotransmission. it is also a postsynaptic antagonist of 5-ht2 and 5-ht3. in addition, it has only a weak affinity for 5-ht1 receptors and has very weak muscarinic anticholinergic and histamine (h1) antagonist properties. we report a case of hypertensive urgency that ensued after a patient took a single low d...
