DB00825LevomentholMenthol is a covalent organic compound made synthetically or obtained from peppermint or other mint oils. Forming clear or white waxy, crystalline substance, menthol is typically solid at room temperature. (-)-Menthol is the naturally-occurring and main form of menthol, and is assigned the (1R,2S,5R) configuration. Menthol mediates anesthetic properties and anti-irritating properties locally, thus it is widely used to relieve minor throat irritations.
DB00540NortriptylineNortriptyline hydrochloride, the N-demethylated active metabolite of amitriptyline, is a dibenzocycloheptene-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, nortriptyline does not affect mood or arousal, but may cause sedation. In depressed individuals, nortriptyline exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Secondary amine TCAs, such as nortriptyline, are more potent inhibitors of norepinephrine reuptake than tertiary amine TCAs, such as amitriptyline. TCAs also down-regulate cerebral cortical β-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H1 receptors, α1-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. Compared to other TCAs, nortriptyline is less toxic and displays less drug interactions [A6584]. As a more selective noadrenaline reuptake inhibitor, nortriptyline is less likely associated with the hypertensive ‘cheese reaction' [A6584]. Nortriptyline exerts less anticholinergic and sedative side effects compared to the tertiary amine TCAs, amitriptyline and clomipramine. Apart from its indication to treat depression, nortriptyline has been investigated in chronic neuropathic pain (unlabeled use), fibromyalgia [A31911], irritable bowel syndrome (unlabeled use), diabetic neuropathy (unlabeled use) [A31912], post-traumatic stress disorder (unlabeled use), and migraine prophylaxis (unlabeled use).
