Micro-K LS is comprised of specially formulated granules. After reconstitution with 2-6 fluid ounces of water and 1 minute of stirring, the suspension is odorless and tasteless.
Each crystal of potassium chloride (KCl) is microencapsulated with an insoluble polymeric coating which functions as a semipermeable membrane; it allows for the controlled release of potassium and chloride ions over an 8- to 10-hour period. The controlled release of K+ ions by the microcapsular membrane is intended to reduce the likelihood of a high localized concentration of potassium chloride at any point on the mucosa of the gastrointestinal tract. Fluids pass through the membrane and gradually dissolve the potassium chloride within the microcapsules. The resulting potassium chloride solution slowly diffuses outward through the membrane.
Micro-K LS is an electrolyte replenisher. The chemical name of the active ingredient is potassium chloride and the structural formula is KCl. Potassium chloride, USP, occurs as a white, granular powder or as colorless crystals. It is odorless and has a saline taste. Its solutions are neutral to litmus. It is freely soluble in water and insoluble in alcohol.
