Trimipramine, sold under the brand name Surmontil among others, is a tricyclic antidepressant (TCA) which is used to treat depression. It has also been used for its sedative, anxiolytic, and weak antipsychotic effects in the treatment of insomnia, anxiety disorders, and psychosis, respectively. The drug is described as an atypical or "second-generation" TCA because, unlike other TCAs, it seems to be a fairly weak monoamine reuptake inhibitor. Similarly to other TCAs however, trimipramine does have antihistamine, antiserotonergic, antiadrenergic, antidopaminergic, and anticholinergic activities. Medical uses
Trimipramines primary use in medicine is in the treatment of major depressive disorder, especially where sedation is helpful due to its prominent sedative effects. The drug is also an effective anxiolytic, and can be used in the treatment of anxiety. In addition to depression and anxiety, trimipramine is effective in the treatment of insomnia, and unlike most other hypnotics, does not alter the normal sleep architecture. In particular, it does not suppress REM sleep, and dreams are said to "brighten" during treatment. Trimipramine also has some weak antipsychotic effects with a profile of activity described as similar to that of clozapine, and may be useful in the treatment of psychotic symptoms such as in delusional depression or schizophrenia.A major systematic review and network meta-analysis of medications for the treatment of insomnia published in 2022 found that trimipramine had an effect size (standardized mean difference (SMD)) against placebo for treatment of insomnia at 4 weeks of 0.55 (95% CI –0.11 to 1.21).
Percutaneous nephrolithotripsy (PNL) is performed via a port created by puncturing the kidney through the skin and enlarging the access port to 1 cm in diameter. Most of the time, cystine stones are too dense to be broken up by shock (ESWL) so PNL is needed.Videos of surgery are available on various websites that show stone removal by percutaneous nephrolithotomy.In February 2017, an article was published in Nature Medicine entitled "Alpha lipoic acid treatment prevents cystine urolithiasis in a mouse model of cystinuria", suggesting that a high dose of the readily available antioxidant, alpha-lipoic acid at 2,700 mg/67 kg body weight daily reduced the incidence of stones. The effects were dose dependent. The results are unprecedented for cystinuria. A clinical trial is underway based on this mouse model. Occurrence in animals
This disease is known to occur in at least four mammalian species: humans, domestic canines, domestic ferrets and a wild canid, the maned wolf of South America. Cystine uroliths have been demonstrated, usually in male dogs, from approximately 70 breeds including the Australian cattle dog, Australian shepherd, Basenji, Basset, Bullmastiff, Chihuahua, Scottish deerhound, Scottish terrier, Staffordshire terrier, Welsh corgi, and both male and female Newfoundland dogs.
