Its action is to inhibit reabsorption of sodium and chloride, and in turn increases the excretion of Sodium, Chloride, Mag, water, potassium, and calcium. Therapeutic effects are to help decrease BP and to mobilize excess fluid. Its absorption rate is 60-70% after oral medication has been taken. The Distribution example is when it crosses over from the placenta to breast milk. Protein binding occurs at 90-91%, and its half-life is 30-60 minutes but increased in renal impairment. Metabolism and excretion are minimally metabolized by the liver. Ways for it to be given are IM, PO, IV. These medications can cause toxicity and interactions with the Lasix and they include, antihypertensive, lithium, digoxin, and corticoid steroids to name a few. Profound diuresis may cause fluid and electrolyte depletion. Excessive dehydration and potassium depletion may occur. Excessive diuresis may cause rapid weight loss, orthostatic hypotension or acute hypotensive episodes. May also cause tinnitus, reversible or permanent hearing loss or reversible deafness.
