Hoffman An irreversible cessation of ciliary movement was observed in ciliary cells exposed to nasal sprays containing Benzalkonium chloride As benzalkonium chloride can cause complete standstill of ciliary beat frequency in vitro in human nasal mucosa, we recommend that this preservative should not be used anymore in topical nasal medications. In the past, I had my patients refill a spray bottle weekly with water and iodine free salt to make additive-free saline solution. This contains the same constituents as Boek's Locke-Ringer's Solution, including Soda Bicarbonate, Potassium and Calcium Chloride, and Salt. Warm Saline Saline solutions can also be used to irrigate the nasal passages and sinuses, for example, using the Grossan Pulsatile Sinus Irrigator . Every doctor tells you to irrigate with warm saline.
Warm solution helps bring more circulation to the area, and besides, it feels good.
Hypertonic Saline Hypertonic saline has been studied recently. By pulling liquid out of the tissue, this can thin the mucus according to some authors. It acts like sea water. Excessive hypertonic solution has been shown to impair movement of cilia. Many of the commercial preparations also contain additives that can irritate.
