abstract::Morphine remains widely used in clinical settings due to its potent analgesic properties. However, one of the gravest risks of all opioids is their ability to induce respiratory depression and subsequent brain hypoxia that can lead to coma and death. Due to these life-threatening effects, our goal was to examine the e...
