Severe adverse effects may include angioedema, low blood pressure, and kidney problems. [4] Use during pregnancy may result in harm to the baby. [4] [1] Use is not recommended during breastfeeding. [1] It works by blocking angiotensin II. [4] Losartan was patented in 1986, and approved for medical use in the United States in 1995.
Serious side effects may include low blood pressure, kidney problems, allergic reactions, and electrolyte problems. [1] Use in pregnancy and breastfeeding is not recommended. [3] Losartan works by blocking the effects of angiotensin II while hydrochlorothiazide works by decreasing the ability of the kidneys to absorb electrolytes. [1]
The choice between the drugs is to a large degree determined by the characteristics of the patient being prescribed for, the drugs' side effects, and cost. Most drugs have other uses; sometimes the presence of other symptoms can warrant the use of one particular antihypertensive. Examples include: Age can affect the choice of medications.
Losartan, the first ARB. Angiotensin II receptor blockers (ARBs), formally angiotensin II receptor type 1 (AT 1) antagonists, [1] also known as angiotensin receptor blockers, [2] [3] angiotensin II receptor antagonists, or AT 1 receptor antagonists, are a group of pharmaceuticals that bind to and inhibit the angiotensin II receptor type 1 (AT 1) and thereby block the arteriolar contraction and ...
H 1 antagonists, also called H 1 blockers, are a class of medications that block the action of histamine at the H 1 receptor, helping to relieve allergic reactions.Agents where the main therapeutic effect is mediated by negative modulation of histamine receptors are termed antihistamines; other agents may have antihistaminergic action but are not true antihistamines.
Antihistamines are drugs which treat allergic rhinitis, common cold, influenza, and other allergies. [1] Typically, people take antihistamines as an inexpensive, generic (not patented) drug that can be bought without a prescription and provides relief from nasal congestion, sneezing, or hives caused by pollen, dust mites, or animal allergy with few side effects.

Cimetidine was the prototypical histamine H 2 receptor antagonist from which later drugs were developed. Cimetidine was the culmination of a project at Smith, Kline & French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist that would suppress stomach acid secretion.
Antihistamines are a class of medications designed to reduce unwanted effects of histamine in the body. Typical antihistamines block specific histamine receptors, depending on what physiological purpose they serve. For example, diphenhydramine (Benadryl™), targets and inhibits the H1 histamine receptor to relieve symptoms of allergic ...
