The company’s research centers on small‐molecule compounds designed to modulate neurotransmitter receptors, with particular emphasis on ampakines—agents that enhance AMPA receptor activity—and cholinesterase inhibitors. These mechanisms aim to stimulate neural pathways involved in breathing regulation and cognitive function. RespireRx’s lead programs include respiratory stimulants targeting conditions such as opioid‐induced respiratory depression and central sleep apnea. By leveraging the ampakine platform, the company seeks to restore normal respiratory drive without the side effects associated with traditional therapies. In parallel, its cholinesterase inhibitor candidates are being explored for potential applications in neurodegenerative diseases, including Alzheimer’s and Parkinson’s, where cholinergic dysfunction contributes to cognitive decline. Founded in the mid‐2000s under the name Cortex Pharmaceuticals and rebranded in 2016, RespireRx has advanced its compounds through preclinical studies and early‐stage clinical trials. The company is headquartered in the United States and collaborates with research institutions and contract research organizations to support its development efforts. RespireRx’s management team brings together scientific expertise in neuroscience and respiratory physiology, guiding its strategy to move lead candidates toward later‐stage clinical evaluation. Looking ahead, RespireRx plans to expand its clinical program pipeline and pursue strategic partnerships to accelerate commercialization. The company continues to engage with regulatory authorities to design pivotal studies that may address unmet medical needs in respiratory insufficiency and cognitive impairment, striving to deliver differentiated therapies for patients worldwide.AI Generated.
