hypertonic seawater solution

Hypertonic seawater solution is a highly concentrated saline solution, typically containing 2.3% sodium chloride (NaCl) in naturally derived seawater, along with minerals and trace elements from marine sources. It is administered topically, most often as a nasal irrigation or spray, to benefit from both osmotic and mechanical actions in the nasal passages. The solution draws out excess fluid from swollen tissues by an osmotic effect, thereby reducing mucosal edema. Clinical studies show that it improves mucociliary clearance, reduces nasal congestion, and provides symptom relief in various ENT (ear, nose, and throat) conditions, including rhinitis, sinusitis, and post-surgical nasal care. It can reduce reliance on medications and accelerate recovery after nasal surgery. Mechanistically, the product's effects are local and physiochemical, with no direct pharmacodynamic target like a small molecule drug. Its primary uses are symptomatic relief in upper respiratory and ENT disorders, immune support, and support in electrolyte imbalance. Unlike pharmaceutical hypertonic saline, which is a purified NaCl solution for intravenous use, hypertonic seawater retains a broad spectrum of minerals and trace elements.
