What mass (mg) of sodium chloride (FD1%=0.576) are required to make 226 ml of the following nose drop? (whole number mg)

0.18g Phenylephrine HCl (FD1% =0.185)

0.1g sodium metabisulphite (FD1%=0.386)

Answer 1

This product is used to treat dryness inside the nose (nasal passages). It helps add moisture inside the nose to dissolve and soften thick or crusty mucus. In babies and young children with stuffy noses who cannot blow their noses, using this product helps to make the mucus easier to remove with a nasal bulb syringe. This helps relieve stuffiness and makes breathing easier.

This product contains a purified gentle salt solution (also called saline or sodium chloride solution). It does not contain any medication.
