U.S. Acute Repetitive Seizures market size and growth rate, 2023 - 2030

Acute recurrent seizures can result from several things, including head injury, stroke, brain tumor, infection, and genetics. Acute repetitive seizures are usually treated with anti-epileptic drugs and, in some cases, with surgery to remove part of the brain.

In an attempt to curb healthcare expenditure, governments across the globe are making continuous efforts to reduce hospital stays, and on-site patient treatment costs through outpatient care models, such as clinic and home healthcare. Emerging economies like India and China are increasingly implementing these healthcare reforms. This factor is expected to propel the growth of the market.

The treatment gap is useful for comparing access to quality care for seizure patients. The treatment gap for low- and middle-income countries, such as India, South Africa, and Brazil, is around 80%, while it is around 60% in developed countries, such as U.S. and UK.

Among the many routes of medicine administration, patients prefer the intranasal route over other types, such as buccal, rectal, and intramuscular routes. Parenteral medications have proven to be the optimal option for outpatient treatment. However, in some countries, such as the Netherlands, caregivers are not qualified for administrating parenteral medications.
