What are the nursing consideration for H2 blockers?
What are the nursing consideration for H2 blockers?
Nursing interventions for patients using H2 antagonists include: Ensure therapeutic levels. Administer drug with or before meals and at bedtime (exact timing varies with product) to ensure therapeutic levels when the drug is most needed. Prevent serious toxicity.
What is your nursing responsibilities for patient taking anxiolytic drugs?
Monitor patient response to therapy (e.g. controlled anxiety, sleep, etc). Monitor for adverse effects (e.g. hypotension, dependence, hepatorenal dysfunction, etc). Evaluate patient understanding on drug therapy by asking patient to name the drug, its indication, and adverse effects to watch for.
Is ranitidine an agonist or antagonist?
They are also called ‘histamine H2-receptor antagonists’ but are commonly called H2 blockers. They include cimetidine, famotidine, nizatidine and ranitidine, and have various different brand names.
Is ranitidine A receptor antagonist?
Ranitidine–a new H2-receptor antagonist. The pharmacokinetics and gastric antisecretory effects of a new histamine H2-receptor antagonist, ranitidine hydrochloride, have been investigated in healthy subjects.
What is an antagonist nursing?
antagonistic muscle. (see illustration.) 1. a substance that tends to nullify the action of another, as a drug that binds to a cellular receptor for a hormone, neurotransmitter, or another drug blocking the action of that substance without producing any physiologic effect itself.
How do H2 receptor antagonists reduce the secretion of acids?
Histamine-2 receptor antagonists (H2RAs) decrease acid secretion by inhibiting histamine-2 receptors on gastric parietal cells. Historically, cimetidine was the first H2RA available. Ranitidine, famotidine and nizatidine are the most popular, although very poorly studied in children.
What is the nurse’s role in the treatment of anxiety?
Nurses play a key role in assessing and treating patients with various anxiety disorders. This process begins by establishing rapport and allaying distress by reassuring and explaining all procedures.

Which of the following H2 receptor antagonists was the first drug approved for clinical use?
The initial H2 blocker approved for use in the United States was cimetidine (1977), which was followed by ranitidine (1983), famotidine (1986), and nizatidine (1988). All four of these agents are available by prescription and as over-the-counter oral formulations.
What is ranitidine mechanism of action?
Mechanism of Action Ranitidine is a competitive inhibitor of histamine H2-receptors. The reversible inhibition of H2-receptors in gastric parietal cells results in a reduction in both gastric acid volume and concentration.
What receptor does ranitidine bind to?
Ranitidine reduces the secretion of gastric acid by reversible binding to histamine (H2) receptors, which are found on gastric parietal cells. This process leads to the inhibition of histamine binding to this receptor, causing the reduction of gastric acid secretion.
What are adrenergic antagonists and how do they work?
Adrenergic antagonists are also referred to as sympatholytics because they lyse, or block, the effects of the sympathetic nervous system. They react with specific adrenergic receptor sites without activating them, thus preventing the typical manifestations of SNS activation.
What are the nursing considerations of ranitidine (Zantac)?

What are the side effects of ranitidine?
Body as a Whole: Hypersensitivity reactions, anaphylaxis (rare). Ranitidine may produce slight elevations in serum creatinine (without concurrent increase in BUN ); (rare) increases in AST, ALT, alkaline phosphatase, LDH, and total bilirubin. Produces false-positive tests for urine protein with Multistix (use sulfosalicylic acid instead).
What is the generic name for ranitidine hydrochloride?
