Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.This product contains two medications, captopril and hydrochlorothiazide. Captopril belongs to a class of drugs known as ACE inhibitors. It works by relaxing blood vessels so blood can flow more easily. Hydrochlorothiazide is a "water pill" (diuretic).

ACE InhibitorsACE inhibitors, or angiotensin (generic name) converting enzyme inhibitors, is a class of drugs that interact with blood enzymes to enlarge or dilate blood vessels and reduce blood pressure. These drugs are used to control high blood pressure (hypertension), treat heart problems, kidney disease in people with diabetes high blood pressure. These drugs also improve the survival rate of people who have survived heart attacks and they prevent early death of people from heart attacks, high blood pressure, and heart failure. Sometimes ACE inhibitors are combined with other drugs for treating a condition.
Examples of ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), and ramipril (Altace). Examples of the most common side effects of this class of drugs are dizziness, headache, cough, rash, chest pain, and rash. There are serious side effects of this drug like kidney failure, severe allergic reactions, and liver dysfunction, or failure. ACE inhibitors all are similar in the way they work; however, they differ in how the body eliminates doses of the drug. Drug interactions, dosage, and pregnancy and safety information should be reviewed prior to taking this medication.
Captopril (Capoten) is an ACE inhibitor prescribed for the treatment of high blood pressure, heart failure, and prevention of kidney failure due to high blood pressure and diabetes. Side effects, drug interactions, warnings and precautions, and efficacy during pregnancy information should be reviewed prior to taking this medication.
Congestive Heart Failure (CHF): Symptoms, Causes, Stages, TreatmentCongestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema. Physical examination, patient history, blood tests, and imaging tests are used to diagnose congestive heart failure. Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart. The prognosis of a patient with congestive heart failure depends on the stage of the heart failure and the overall condition of the individual.
Diabetes (Type 1 and Type 2)Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.

High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis.
Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.

- and drug reactions.
- damage to the recurrent laryngeal nerve,
- bleeding or hematoma,
