Background: Hyperosmolar therapy is an essential treatment method for increased intracranial pressure and cerebral edema. Mannitol and hypertonic saline are frequently used in clinical practice; however, more helpful recommendations are needed for the optimal management of cerebral edema in terms of the choice, dosage, and timing of these medications. This study aimed to introduce the characteristics and relative strengths of two agents, i.e., mannitol and hypertonic saline, and review clinical data supporting their use in various diseases. Current Concepts: Hyperosmolar therapy reduces intracranial pressure by removing water from the brain tissue and transferring it to the vascular space by creating an osmotic gradient. Mannitol improves cerebral blood flow by reducing the hematocrit, decreasing blood viscosity, and increasing deformability of red blood cells. Hypertonic saline increases intravascular volume, transiently increases cardiac output, and improves tissue oxygen partial pressure in the brain. Hypertonic saline has several advantages over mannitol, including quicker onset and longer-lasting reduction in intracranial pressure. However, no significant differences are noted in clinical, functional outcomes, or mortality between the two treatment agents. Discussion and Conclusion: Both mannitol and hypertonic saline are effective in reducing increased intracranial pressure. Clinicians should be able to select an appropriate agent in different clinical situations based on available evidence and patients’ individual medical conditions.
