What medicine is Captopril?

What is Captopril for?

Captopril is a medicine to treat high blood pressure (hypertension). Captropril belongs to a group of heart drugs called ACE inhibitors.

This drug works by inhibiting the angiotensin-converting enzyme which then decreases the amount of angiotensin II (a hormone that constricts blood vessels and increases blood pressure)

Apart from treating hypertension, captopril also helps prevent strokes, heart attacks, diabetic nephropathy, and kidney problems. How to use, captopril dosage and captopril side effects will be explained further below.

What is the dose of Captopril for adults?

For high blood pressure or hypertension, the dosage for using the drug captopril is as follows:

Hypertension is another name for high blood pressure. Blood pressure itself is the force of blood flow from the heart pushing it against the walls of blood vessels (arteries).

The strength of this blood pressure can change over time, influenced by what activity the heart is doing (for example, exercising or resting) and the resistance of the blood vessels.

High blood pressure is a condition in which blood pressure higher than 140/90 millimeter of mercury (mmHG). The number 140 mmHG refers to a systolic reading, when the heart pumps blood around the body.

Meanwhile, the number 90 mmHG refers to a diastolic reading, when the heart is relaxed while refilling its chambers with blood. The following dosage is used:

  • Initial dose: captopril 25 mg orally, 2-3 times a day one hour before meals.
  • Follow-up dose: captopril 25-150 mg orally, 2-3 times a day one hour before meals.

For heart failure, the dosage for using the drug captopril is:

Heart failure is a term used to describe a heart condition that is not functioning properly and is unable to pump blood around the body efficiently.

In people with heart failure, blood moves around the body through the heart more slowly. Due to an insufficient amount of blood, the chambers of the heart respond by stretching to hold more blood or by stiffening and thickening.

This condition can help to keep the blood moving, but the heart muscle will eventually weaken and can't work effectively.

As a result, it triggers the kidneys to retain more fluid and salt. Eventually, fluids build up in the body parts and cause blockages. Heart failure is a different condition from a heart attack and a weak heart.

  • Initial dose: captopril 25 mg orally 3 times a day (6.25-12.5 mg orally, 3 times a day if the volume is reduced or hypotensive).
  • Follow-up dose: after the three times daily dose of captopril 50 mg is reached, additional follow-up doses should be delayed by at least 2 weeks to see if a satisfactory response occurs. Many of the patients studied progressed at 50-100 mg three times a day. Captopril should generally be used in conjunction with diuretics and digitalis.

For left ventricular damage, the dosage for using captopril is:

When the left side of the heart doesn't pump blood out, blood builds up in the heart or blocks organs or tissues, causing blood to build up in the circulatory system.

If the left heart fails, the right heart system will be congested due to the accumulated blood. Inside, the heart is blocked from excess contractions that push up blood and can lead to heart failure.

However, if the right side of the heart fails, the left heart is affected and it can also cause heart failure. The following dosage is used:

  • Initial dose: 6.25 mg orally for 1 dose, then 12.5 orally 3 times a day.
  • Increase in dosage: the dose is increased to 25 mg orally 3 times a day over the next several days.
  • Follow-up dose: the dose is increased to a target dose of captopril 50 mg orally 3 times a day for up to several weeks thereafter to the patient's tolerance.

Therapy may be started 3 days after myocardial infarction (damage to the myocardium of the heart). Captropil can also be used in patients in other postmyocardial infarction medications such as thrombolytics, aspirin, beta blockers.

For diabetic nephropathy, the dosage for captropil is:

Diabetic nephropathy is a type of progressive kidney disease that occurs in people who have diabetes. Experts estimate that 20-40 percent of people with diabetes will experience diabetic nephropathy at some point in their life.

Diabetic nephropathy progresses slowly. The median time taken to progress from early stage to end-stage renal failure to kidney disease was 23 years. However, not everyone progresses to stage five of the disease. The following dosages are used:

  • The recommended long-term dose is 25 mg orally three times a day.

For emergency hypertension, the dosage for using the drug captopril is:

  • When indicated that a sudden increase in blood pressure is indicated, continue diuretic therapy and discontinue any current drug therapy, and give captopril 25 mg 2-3 times a day under close observation.
  • Increase the dose every 24 hours or less until a satisfactory response is achieved or the maximum dose has been reached.

For kidney stones, the dosage for using the drug captopril is:

Kidney stones are conditions that occur due to hard deposits formed from amino acids in the urine. The process is called nephrolithiasis.

Kidney stones or urinary stones are usually very small or can reach about a few inches. Larger sizes of stones that fill the tubes that carry urine from the kidneys to the bladder are called staghorn stones. The following is the dosage for the use of the drug:

  • Initial dose: Captopril 25 mg orally two to 3 times a day one hour before meals. The initial dose will probably be titrated as the patient tolerates about every 1-2 weeks to reduce the level of cystinuria.

What is the dose of Captopril for children?

The safety and effectiveness of captopril have not been established in pediatric patients (under 18 years of age).

In what dosage is Captopril available?

Captopril dosage is:

  • Tablet, oral: 6.25 mg, 12.5 mg, 25 mg, 50 mg, 100 mg.
