Micro-K (potassium chloride extended-release) ® Extencaps® capsules / Micro-K® 10
(Potassium Chloride Extended-release Capsules, USP)
600 mg (8 mEq K)/750 mg (10 mEq K)
Micro-K (potassium chloride extended-release) ® Extencaps® capsules and Micro-K (potassium chloride extended-release) ® 10 Extencaps® capsules are oral dosage forms of microencapsulated potassium chloride containing 600 and 750 mg, respectively, of potassium chloride USP equivalent to 8 and 10 mEq of potassium.
Dispersibility of potassium chloride (KCl) is accomplished by microencapsulation and a dispersing agent. The resultant flow characteristics of the KCl microcapsules and the controlled release of K+ ions by the microcapsular membrane are intended to avoid the possibility that excessive amounts of KCl can be localized at any point on the mucosa of the gastrointestinal tract.
Each crystal of KCl is microencapsulated by a patented process with an insoluble polymeric coating which functions as a semi-permeable membrane; it allows for the controlled release of potassium and chloride ions over an eight-to-ten-hour period. Fluids pass through the membrane and gradually dissolve the potassium chloride within the micro-capsules. The resulting potassium chloride solution slowly diffuses outward through the membrane. Micro-K (potassium chloride extended-release) ® and Micro-K (potassium chloride extended-release) ® 10 are electrolyte replenishers. 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.
The inactive ingredients are edible ink, ethylcellulose, FD&C blue #2 aluminum lake, FD&C yellow #6, gelatin, magnesium stearate, sodium lauryl sulfate, titanium dioxide. May contain FD&C red #40 and yellow #6 aluminum lakes.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart problems, kidney problems, high levels of potassium in the blood.
Due to rare reports of stomach/intestinal ulcers and bleeding with sustained-release potassium products, taking a liquid form of potassium is preferred. Tell your doctor or pharmacist if you have throat/stomach/intestinal problems such as blockage, narrowing, or ulcers.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription...
