Beta blockerMedication class with multiple usesBeta blockers, also spelled β-blockers and also sometimes known as β-adrenergic receptor antagonists, are a class of medications predominantly used to manage abnormal heart rhythms (arrhythmia) and to protect the heart from a second heart attack after the first one (secondary prevention). They are also used widely to treat high blood pressure, though they are no longer the first choice for initial treatment of most people.
Heart failureFailure of the heart to provide sufficient blood flow throughout the bodyMedical conditionHeart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart's ability to fill with and pumpblood. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling.
Blood pressureBlood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
HypertensionLong-term high blood pressure in the arteriesMedical conditionHypertension, also known as high blood pressure, is a long-termmedical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms itself. It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia.
Angiotensin II receptor blockerAngiotensin II receptor blockers (ARBs), formally angiotensin II receptor type 1 (AT1) antagonists, also known as angiotensin receptor blockers, angiotensin II receptor antagonists, or AT1 receptor antagonists, are a group of pharmaceuticals that bind to and inhibit the angiotensin II receptor type 1 (AT1) and thereby block the arteriolar contraction and sodium retention effects of renin–angiotensin system.
HeartOrgan found in humans and other animalsThe heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. The heart and blood vessels together make up the circulatory system. The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs.
BronchospasmBronchospasm or a bronchial spasm is a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the release (degranulation) of substances from mast cells or basophils under the influence of anaphylatoxins. It causes difficulty in breathing which ranges from mild to severe. Bronchospasms occur in asthma, chronic bronchitis and anaphylaxis.
ACE inhibitorAngiotensin-converting-enzyme inhibitors (ACE inhibitors) are a class of medication used primarily for the treatment of cardiovascular and kidney diseases. This class of medicine works by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
PregnancyTime of offspring development in mother's bodyMedical conditionPregnancy is the time during which one or more offspringgestates inside a woman's uterus. A multiple pregnancy involves more than one offspring, such as with twins. Conception usually occurs following vaginal intercourse, but can also occur through assisted reproductive technology procedures. A pregnancy may end in a live birth, a miscarriage, an induced abortion, or a stillbirth.
BreastfeedingFeeding of infants/toddlers with breast milkAn infant being breastfedVideo summary of article with Breastfeeding, also known as nursing, is the process whereby breast milk is fed to an infant or toddler. Infants may suckle directly from the breast, or milk may be extracted with a breast pump and then fed to the infant. The World Health Organization (WHO) recommends that breastfeeding begin within the first hour of a newborn's birth and continue as the baby wants.
Generic drugA generic drug is a pharmaceutical drug that contains the same chemical substance as a proprietary drug that was originally protected by chemical patents. Generic drugs are allowed for sale after the patents on the original drugs expire. Because the active chemical substance is the same, the medical profile of generics is equivalent in performance compared to their performance at the time when they were patented drugs.
