Potassium is a vital mineral for human health. It is found in many foods, including fruits and vegetables. Potassium helps to regulate blood pressure and heart rate. It is also necessary for proper muscle function. A lack of potassium can lead to fatigue, muscle cramps, and an irregular heartbeat. Too much potassium can be dangerous and cause kidney failure.

PHARMACOKINETICS

After oral administration, potassium is absorbed from the gastrointestinal tract and distributed throughout the body. It is excreted by the kidneys.

The half-life of potassium in blood is about 1 hour.

INDICATIONS AND USAGE

Potassium supplements are indicated for the treatment of potassium deficiency.

Potassium supplements may also be used to treat high blood pressure and heart arrhythmias.

Potassium toxicity can occur if too much potassium is taken at one time. Symptoms of potassium toxicity include muscle weakness, paralysis, and heart failure. Potassium toxicity is a medical emergency and requires immediate treatment.

The LD50 (lethal dose that kills 50% of the population) of potassium in rats is 2,500 mg/kg. This means that it would take approximately 175 grams (6 ounces) of potassium to kill a 150-pound person.

SAFETY IN PREGNANCY AND LACTATION

There is no definitive evidence on the safety of potassium supplements in pregnancy or lactation. Therefore, they should be used with caution in these populations.

DOSAGE AND ADMINISTRATION

The recommended daily intake of potassium is 4,700 mg per day for adults.

Potassium supplements are available in tablet or capsule form. They should be taken with meals to reduce the risk of stomach upset.

People with kidney disease or other medical conditions should speak to their doctor before taking potassium supplements.

Monitoring and Laboratory Tests

Potassium levels can be measured with a blood test. A serum potassium level of less than 3 mEq/L is considered low. A level of more than 5 mEq/L is considered high.

People with kidney disease or other medical conditions should have their potassium levels monitored by their doctor.
