Elagolix, sold under the brand name Orilissa, is a gonadotropin-releasing hormone antagonist (GnRH antagonist) medication which is used in the treatment of pain associated with endometriosis in women. It is also under development for the treatment of uterine fibroids and heavy menstrual bleeding in women. The medication was under investigation for the treatment of prostate cancer and enlarged prostate in men as well, but development for these conditions was discontinued. Elagolix is taken by mouth once or twice per day. It can be taken for up to 6 to 24 months, depending on the dosage.Side effects of elagolix include menopausal-like symptoms such as hot flashes, night sweats, insomnia, amenorrhea, mood changes, anxiety, and decreased bone density, among others. Elagolix is a GnRH antagonist, or an antagonist of the gonadotropin-releasing hormone receptor (GnRHR), the biological target of the hypothalamic hormone gonadotropin-releasing hormone (GnRH). By blocking the GnRHR, it dose-dependently suppresses the gonadal production and hence circulating levels of sex hormones such as estradiol, progesterone, and testosterone. Elagolix is a short-acting GnRH antagonist, and can be used to achieve either partial or more substantial suppression of sex hormone levels. Reduced estrogen levels in the endometrium are responsible for the efficacy of elagolix in the treatment of endometriosis.Elagolix was first described in 2008 and was approved for medical use in July 2018. It has been described as a "second-generation" GnRH modulator due to its non-peptide and small-molecule nature and its oral activity.
These blisters are often described as having a "tapioca pudding" appearance. After a few weeks, the small blisters eventually disappear as the top layer of skin falls off. These eruptions do not occur elsewhere on the body. The eruptions may be symmetrical. Causes
The exact causes of dyshidrosis are unknown. Food allergens may be involved in certain cases. Cases studies have implicated a wide range of foods including tuna, tomato, pineapple, chocolate, coffee, and spices among others. A number of studies have implicated balsam of Peru. A 2013 study found that dyshydrosis on the hands increased among those allergic to house dust mites, following inhalation of house dust mite allergen.Id reaction and irritant contact dermatitis are possible causes. Diagnosis
Dyshidrosis is diagnosed clinically, by gathering a patients history and making careful observations (see signs and symptoms section). Severity of symptoms can also be assessed using the dyshidrotic eczema area and severity index (DASI). The DASI has been designed for clinical trials and is not typically used in practice. Treatment
There are many treatments available for dyshidrosis. However, few of them have been developed or tested specifically on the condition. Barriers to moisture and irritants, including barrier creams and gloves. Topical steroids – while useful, can be dangerous long-term due to the skin-thinning side-effects, which are particularly troublesome in the context of hand dyshidrosis, due to the amount of toxins and bacteria the hands typically come in contact with.
