Delirium is commonly associated with myriad conditions and requires variety of medications. Early recognition and on-time treatment can help to reduce morbidity, length of hospital stay, health care costs, and mortality in patients. According to the Marie Curie, a registered organization in the U.K. which provides nursing and hospice care to elderly patients and they have mentioned on their website that many patients develop delirium in the last few days of their life which can cause agitation or restlessness. This is sometimes called as terminal restlessness or terminal agitation. The first-generation antipsychotics are the first choice of treatment for agitation in delirium management patients, followed by second-generation antipsychotics and Benzodiazepines.
Global Agitation in Delirium Management Market - Impact of the Coronavirus (COVID-19) Pandemic
The COVID-19 pandemic is expected to drive the growth of the global agitation in delirium management market over the forecast period. According to the research carried out by researchers from the Universitat Oberta de Catalunya (UOC), published in the Journal of Clinical Immunology and Immunotherapy on November 4, 2020, symptoms like fever and increased invasive mechanical ventilation during COVID-19 increases the risks of delirium. According to the same source, the researchers also found that coronavirus disease not only damages the lungs and other organs such as the kidneys and heart but also affects the central nervous system. It produces neurocognitive alterations such as headaches, delirium, and psychotic episodes in the COVID-19 patients.
Thus, the researchers provided three hypotheses in order to explain how the coronavirus affects the central nervous system, which can lead to delirium in the COVID-19 patients. They are due to: hypoxia or neuronal oxygen deficiency, inflammation of the brain tissue due to cytokine storm, and the ability of the virus to cross the blood-brain barrier which directly affects the brain.
The global agitation in delirium management market is estimated to be valued at US$ 212.7 Mn in 2020 and is expected to exhibit a CAGR of 4.3% over the forecast period (2020-2027).

Delirium is a neurological condition which leads to disturbances in the mental abilities of a person. It causes mental confusion and emotional disruption. Delirium can be caused due to various factors such as old age, exposure to certain medications, alcohol abuse, surgery or other medical procedures and factors such as exposure to toxic or infectious agents, physical trauma, diet, and other behavioral and occupational factors. There are two types of delirium: Hyperactive delirium and Hypoactive delirium. In hyperactive delirium, patients become overactive (agitation in delirium). Currently, market players are carrying out research and development activities for evaluating new medicines for the management of agitation in delirium among the patients.
Research institutes and market players are indulged in conducting research and development activities for testing the safety and efficacy of the drugs for the treatment of agitation in delirium in critically ill ICU patients. For instance, in 2017, researchers at the University of California, San Diego, reported that sleep deprivation post-surgery causes delirium (confusion) in patients in the intensive care unit (ICU). Thus, they are conducting clinical trials for studying the role of Ramelteon, a medication that mimics the activity of melatonin (hormone which controls the body’s circadian rhythm or sleep – wake cycle) in improving the sleep quality, thus improving sleep quality is expected to help in preventing occurrence of delirium in the patients post open-heart surgery. The study is expected to be completed by December 1, 2021.
Market players are indulged in launching new first-generation antipsychotic drugs for the treatment of delirium, which is expected to spur the growth of the global agitation in delirium management market.
