Slow-K Description
Slow-K, potassium chloride extended-release tablets USP, is a sugar-coated (not enteric-coated) tablet for oral administration, containing 600 mg of potassium chloride (equivalent to 8 mEq) in a wax matrix. This formulation is intended to provide an extended-release of potassium from the matrix to minimize the likelihood of producing high, localized concentrations of potassium within the gastrointestinal tract.
Slow-K is an electrolyte replenisher. Its chemical name is potassium chloride, and its structural formula is KCI. Potassium chloride USP is a white, granular powder or 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.
Inactive Ingredients. Acacia, cetostearyl alcohol, gelatin, iron oxide, magnesium stearate, parabens, polyvinyl-pyrrolidone, sodium benzoate, starch, sucrose, talc, and titanium dioxide.
Slow-K - Clinical Pharmacology
The potassium ion is the principal intracellular cation of most body tissues. Potassium ions participate in a number of essential physiological processes, including the maintenance of intracellular tonicity, the transmission of nerve impulses, the contraction of cardiac, skeletal, and smooth muscle, and the maintenance of normal renal function.
The intracellular concentration of potassium is approximately 150 to 160 mEq/L. The normal adult plasma concentration is 3.5-5.0 mEq/L. An active ion transport system maintains this gradient across the plasma membrane.
