1. What Glensoludex soluble tablets are and what they are used for
Glensoludex soluble tablets contain the active substance dexamethasone. Glensoludex belongs to a group of medicines called steroids (the full name is ‘corticosteroids’). Corticosteroids occur naturally in the body, and help to maintain health and well-being.
Dexamethasone is a synthetic glucocorticoid (adrenocortical hormone).
Boosting your body with extra corticosteroid (such as dexamethasone) is an effective way to treat various illnesses involving inflammation in the body.
Glensoludex soluble tablets reduce this inflammation, which could otherwise go on making your condition worse. You must take this medicine regularly to get the maximum benefit from it.
Glensoludex soluble tablets are used for one of the following:
- where your natural corticosteroid levels have been reduced and you need to replace them
- where swelling of the brain has occurred
- if you are having tests for diseases which may decrease your natural corticosteroid level, such as Cushing’s syndrome (a hormonal disorder)
- to reduce inflammation and suppress the immune system in:
- allergy (hypersensitivity)
- polymyalgia rheumatica (chronic inflammation of the larger arteries), polyarteritis nodosa (chronic inflammation of small and medium arteries)
- blood disorders including haemolytic anaemia (disorder which breaks down red blood cells), leukaemia (cancer of the blood), myeloma (bone marrow tumour)
- Crohn’s disease, ulcerative colitis (inflammation of the bowel), hepatitis
- polymyositis (inflammation of muscles)
- increased pressure in the head not linked to tumours, worsening of multiple sclerosis
- inflammation of the eye
- inflammation of the kidney
- breathing problems including chronic bronchial asthma and chronic obstructive pulmonary disease (COPD) which may show as shortness of breath during exercise, difficulty breathing in and out deeply, persistent cough and croup. (Disorders where there is inflammation of the lung).
- rheumatoid arthritis (painful joint disease), rheumatism, inflammation of a wide area of the body
- chronic and severe diseases of the skin (including Stevens-Johnson syndrome and a rare condition known as mycosis fungoides)
- leukaemia of the lymphatic system, Hodgkin’s and Non-Hodgkin’s lymphoma, breast cancer that has spread around the body, Kahler’s disease (cancer of blood cells) and high calcium levels caused by this disease
- after organ transplants and to prevent nausea and vomiting following chemotherapy
Glensoludex is used as a treatment of coronavirus disease 2019 (COVID-19) in adult and adolescent patients (aged 12 years and older with body weight at least 40 kg) with difficulty breathing and need of oxygen therapy.
