if they are experiencing two or more migraines per week, if their attacks last more than 48 hours, or if they have ineffective responses or contraindications to abortive therapy.1–5 Although numerous medications are used in the management of migraine (Table 1), the commonly used agents that have been studied and that have reported efficacy include the beta blockers, the tricyclic antidepressant...

In a double-blind study the advantages of a once-a-day dosage of a tricyclic antidepressant as against a thrice daily dosage regimen was evaluated using dothiepin (Prothiaden) and matching placebo tablets. Twenty eight adult patients of both sexes participated in the study and were randomly allocated to drug treatment. Out of 28 patients who received dothiepin, 17 showed good improvement, in 6 ...

We examined Cunninghamella elegans to determine its ability to transform amoxapine, a tricyclic antidepressant belonging to the dibenzoxazepine class of drugs. Approximately 57% of the exogenous amoxapine was metabolized to three metabolites that were isolated by high-performance liquid chromatography and were identified by nuclear magnetic resonance and mass spectrometry as 7-hydroxyamoxapine ...

Reprint requests to Dr. L.M. Sabet, Health Sciences Centre, Department of Pathology, London, Canada N6A 5CI. The pathophysiological effects and clinical features of overdosage with tricyclic antidepressants have been described in detail (Moraguerra, 1977; Petit, 1977; Bilgi, 1979). However, published accounts of morphological changes in the brain are scarce and lacking in detail. We are not awa...

Acute cerebellitis is a rare inflammatory disease involving the cerebellum and is characterized by acute compromise of cerebellar functions. It most frequently originates from infectious causes, although cases of cerebellitis associated with other causes have also been reported. This report discusses a case of cerebellitis developing in a 4-year-old girl who had to be intubated after accidental...

which drugs can interact: enzymes (e.g. neostigmine and acetyl cholinesterase), membrane carriers (e.g. tricyclic antidepressants and catecholamine uptake-1), ion channels (e.g. nimodipine and voltage-gated Ca2þ channels) and receptors. This article is concerned with the receptor and describes the dynamics of drug–receptor interaction, agonists, antagonists, partial agonists and inverse agonist...

With the widespread use of tricyclic antidepressant drugs, the relationship between the concentration of the drug in the plasma and the therapeutic response is of considerable interest. We describe a double-isotope derivative dilution procedure for measuring plasma nortriptyline. In the method, [14C]nortriptyline is used for estimating procedural losses and [3H]acetic anhydride for derivative f...

Fibromyalgia is a complex chronic condition characterized by pain, physical fatigue, sleep disorder and cognitive impairment. Evidence-based guidelines recommend antidepressants as treatments of fibromyalgia where tricyclics are often considered to have the greatest efficacy, with amitriptyline often being a first-line treatment. Amitriptyline evokes a preferential reduction in pain and fatigue...
