Developed by Russian researchers in the 1980s, Semax is a synthetic peptide used clinically in Russia for various neurological conditions, though it remains a research chemical in most of the world. Understanding what is Semax peptide used for reveals its multifaceted potential in neuroprotection, mood regulation, and cognitive enhancement.

According to the American Heart Association and American Stroke Association guidelines, a calcium channel blocker is the only pharmacological treatment with established effectiveness for improving outcomes in patients following a subarachnoid hemorrhage. The specific drug used for this purpose is nimodipine, administered to reduce the risk of delayed cerebral ischemia (DCI) caused by vasospasm.

With a global market value of approximately $1.62 billion in 2022, the **what is the market for aneurysmal subarachnoid hemorrhage drugs?** is driven by the high mortality rates and severe complications associated with this life-threatening form of stroke. This market is marked by ongoing innovation and a focus on improving patient outcomes through both standard and emerging pharmacological interventions.

Nimodipine is the only FDA-approved medication shown to improve outcomes by reducing neurological deficits after a specific type of brain bleed. This article explores what is the drug nimodipine used for, focusing on its critical application in managing subarachnoid hemorrhage complications.

Studies have shown that lower plasma magnesium levels may contribute to a higher risk of ischemic stroke, prompting interest in supplementation. However, the question of which magnesium is best for stroke patients is complex and depends on the treatment stage, with the optimal form for acute care differing significantly from long-term recovery strategies.

Originally developed as an antiviral drug for influenza in the 1960s, the discovery of amantadine's neurological effects was serendipitous and has led to its current use for movement disorders. What does amantadine do to the brain? The answer lies in its multi-layered interaction with key neurotransmitter systems.

As the only FDA-approved medication demonstrated to modestly prolong survival in ALS patients, riluzole works by targeting the complex glutamatergic system to block glutamate release and prevent neurotoxicity. Its multifaceted mechanism provides a neuroprotective effect that helps to manage conditions linked to excessive glutamate signaling.

Glutamate is the most abundant excitatory neurotransmitter in the human body, but its dysregulation is linked to numerous neurodegenerative diseases [1.2.1]. So, what is the mechanism of action of troriluzole? This third-generation prodrug primarily works by modulating and normalizing synaptic glutamate levels [1.3.1, 1.2.2].

While primarily known as a first-line treatment for Type 2 diabetes, a growing body of research highlights the multifaceted relationship between metformin and the nervous system, with effects ranging from potential neuroprotection to adverse outcomes. This complex interaction hinges on various mechanisms, including its impact on metabolism, inflammation, and nutrient absorption, which can both protect and potentially harm nerve health. Understanding this dual nature is crucial for patients and healthcare providers alike.

Studies suggest that certain blood-brain barrier-crossing ACE inhibitors, like ramipril, may be associated with less cognitive decline in older adults with high blood pressure. This raises the important question: **how does ramipril affect the brain?** The answer involves its action on the central renin-angiotensin system, cerebral blood flow, and neuroprotective pathways.
