How should I prepare eye drops containing 300 mg each of potassium iodide and sodium iodide with 30 mg of HPMC for a 10 ml collyrium, given that HPMC swells in water and makes the solution impossible to filter through a 0.22 micrometer membrane filter, thereby rendering filtration after addition useless; is the current method of placing the salts and HPMC together in an eye drop bottle and adding sterile water from an ampoule via a syringe and needle appropriate?
