Ulcer Medications: Common medications include proton pump inhibitors (PPls) and H2-receptor antagonists. They work by reducing stomach acid production, helping to heal ulcers and prevent their recurrence.
PPls, such as omeprazole, inhibit the acid secretory pump, while H2-receptor antagonists, like famotidine, decrease gastric acid production by blocking histamine receptors in the stomach lining.
PPIs are particularly effective in reducing gastric acid secretion and are often used in the treatment of peptic ulcer disease and
GER 1 D.
ACE Inhibitors, Beta Blockers, and Angiotensin Receptor Blockers:

• ACE Inhibitors (e.g., lisinopril) help relax blood vessels and lower blood pressure by inhibiting the conversion of angiotensin I to angiotensin Il, a potent vasoconstrictor. They are commonly used in the management of hypertension and heart failure.Beta Blockers (e.g., metoprolol) reduce heart rate and workload by blocking beta-adrenergic receptors, which decreases cardiac output and blood pressure. They are used in treating hypertension, angina, and heart failure.

Angiotensin Receptor Blockers (ARBs)
(e.g., losartan) block the effects of angiotensin Il, leading to vasodilation and reduced blood pressure. ARBs are often used as an alternative to ACE inhibitors, especially in patients who experience cough as a side effect of ACE inhibitors.

Digoxin: Used for heart failure and atrial fibrillation. Monitor for dig toxicity (symptoms include nausea, vomiting, and visual disturbances). Key labs include serum digoxin levels and electrolytes (especially potassium), as hypokalemia can increase the risk of digoxin toxicity.
Digoxin's therapeutic range is narrow, and careful monitoring is essential to avoid toxicit 2 y.

Medications for N/V: Common agents include ondansetron and promethazine.They work by blocking specific receptors in the brain that trigger nausea. Nursing assessment includes monitoring for effectiveness and side effects, such as sedation and extrapyramidal symptoms.

Ondansetron is a serotonin antagonist, effective in preventing nausea and vomiting associated with chemotherapy and surger

3 Y.

Diuretics: Used to manage fluid retention.
Common types include loop diuretics (e.g., furosemide) and thiazide diuretics. Monitor for electrolyte imbalances and assess for signs of dehydration. Loop diuretics can cause significant potassium loss, necessitating regular monitoring of electrolyte levels. Furosemide is
particularly effective in patients with heart failure and edema.
GERD Medications: Treatment often includes PPls and H2-receptor antagonists. Patient education should focus on lifestyle modifications and medication adherence. PPls should be taken before meals to maximize their

taken before meals to maximize their effectiveness. Long-term use of PPls can increase the risk of Clostridium difficile infection and pneumoni 4 a.

Antacids: Commonly used to neutralize stomach acid. Adverse effects may include constipation or diarrhea, depending on the type. For example, aluminum-based antacids can cause constipation, while magnesium-based ones may lead to diarrhea. Antacids can interfere with the absorption of other medications, so timing of administration is importan 5 t.
Dopamine Antiemetics: Medications like metoclopramide are used to treat nausea and vomiting by enhancing gastrointestinal motility. They can also be used to treat gastroparesis by increasing gastric emptying. Metoclopramide is effective in increasing-gastric motility and is often used in diabetic gastroparesi 6 s.
Gastrointestinal Emptying: Medications like erythromycin can facilitate gastric emptying by stimulating motility, often used in diabetic gastroparesis.

Erythromycin acts as a motilin receptor agonist, promoting gastric motilit 7 y.

Proton Pump Inhibitors: Patient teaching should include the importance of taking these medications before meals and
potential side effects like headache and gastrointestinal disturbances. Long-term use can increase the risk of Clostridium
difficile infection and pneumonia.
Aldosterone Receptor Antagonists:
Monitor labs for potassium levels and assess for signs of hyperkalemia, as these medications can cause potassium retention. Spironolactone is a common aldosterone antagonist used in heart failure and hypertensio 8 n.
Loop Diuretics Side Effects: Common side effects include electrolyte imbalances, dehydration, and ototoxicity. Monitor patients closely for these issues, especially those with renal impairment or on concurrent ototoxic drugs. Furosemide, a loop diuretic, is particularly noted for these side effect 2 s.

Gastrointestinal Medications

The sources discuss several classes of medications used to treat gastrointestinal issues, particularly those related to peptic ulcer disease (PUD) and gastroparesis.

Proton Pump Inhibitors (PPIs):

Mechanism of Action: PPIs are a class of drugs that work by reducing stomach acid production. The source "Proton Pump Inhibitors (PPI) - StatPearls" notes that they are FDA-approved for several conditions including esophagitis, non-erosive reflux disease, peptic ulcer disease, prevention of NSAID-induced ulcers, Zollinger-Ellison Syndrome, and as part of triple therapy for Helicobacter pylori infections.
Indications: According to "Proton Pump Inhibitors (PPIs): What They Are & Side Effects - Cleveland Clinic", PPIs are used to treat:
GERD (Chronic acid reflux): They relieve symptoms and allow the esophagus to heal by reducing stomach acid.
Stomach (peptic) and duodenal ulcers: They help heal and prevent ulcers caused by stomach acid and NSAIDs.
H. pylori infection: They are used in combination with antibiotics to increase stomach pH and enhance antibiotic effectiveness.
Zollinger-Ellison syndrome: They counteract excess stomach acid production caused by tumors.
Duration of Treatment and Side Effects: The source "Proton Pump Inhibitors Educational Pack / Adult dyspepsia guideline" highlights that long-term PPI treatment can lead to side effects, including an increased risk of fractures, infections, and low magnesium. It is recommended to discontinue PPIs when no longer needed, either by stopping immediately, taking them only when symptomatic, or gradually reducing the dose.
Specific PPIs Mentioned: Omeprazole, Esomeprazole, Lansoprazole, Dexlansoprazole, Pantoprazole, and Rabeprazole are listed as FDA-approved PPIs.

H2 Blockers:

Mechanism of Action: H2 receptor antagonists (H2 blockers) are another class of drugs that reduce stomach acid.
Indications: "H2 Blockers - StatPearls" states that H2 blockers are approved for short-term use in treating uncomplicated GERD, gastric or duodenal ulcers, gastric hypersecretion, and mild to infrequent heartburn or indigestion. IV famotidine has specific short-term and maintenance therapy indications for various ulcer and GERD-related conditions.
Adverse Effects: Potential adverse effects of H2 blockers on the central nervous system are noted, including induced adverse CNS reactions with long-standing secondary mania and epileptic seizures, as well as sleep disturbance.

Antacids:

Mechanism of Action: Antacids work by neutralizing stomach acid.
Role in Treatment: The source "Proton Pump Inhibitors Educational Pack / Adult dyspepsia guideline" mentions that antacids can be taken if symptoms persist after stopping a PPI. The source "An expert opinion on antacids: A review of its pharmacological properties and therapeutic efficacy - F1000Research" is cited but no detailed information on antacids' pharmacological properties or therapeutic efficacy is provided in the excerpts.

Prokinetic Agents:

Mechanism of Action: Prokinetic agents stimulate contractions along the gastrointestinal tract, helping to move food along through peristalsis.
Examples and Subclasses: "Prokinetic Agents: Examples, Conditions Treated, Side Effects - Cleveland Clinic" categorizes prokinetic agents into subclasses:
Cholinergic agonists: Mimic acetylcholine to stimulate intestinal muscle contraction (e.g., baclofen, bethanechol, neostigmine, pyridostigmine).
Motilin agonists (macrolide antibiotics): Mimic motilin to stimulate contractions in the small intestine (e.g., erythromycin, azithromycin).
Serotonin agonists: Mimic serotonin to stimulate intestinal contractions and stomach emptying (e.g., cisapride, prucalopride, tegaserod).
Dopamine antagonists: Prevent dopamine from binding to nerve cells, countering dopamine's effect of reducing GI movement and causing LES relaxation (e.g., metoclopramide, domperidone).
Gastroparesis Treatment: "Erythromycin for gastroparesis (delayed stomach emptying) | NICE" discusses erythromycin as a macrolide antibiotic used off-label or without a license for gastroparesis. The condition is described as the stomach not emptying quickly, leading to symptoms like feeling full quickly, bloating, upper abdominal pain, and nausea/vomiting.

Antimicrobial Drugs for H. pylori:

Role in PUD: Helicobacter pylori (H. pylori) infection is identified as a cause of PUD.
Antibiotics: "Anti-ulcer agents - Wikipedia" lists antibiotics used for H. pylori eradication as part of combination therapy to minimize duodenal ulcer recurrence.
Clarithromycin: A macrolide antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, killing H. pylori in the gastric region. Available as oral tablets.
Metronidazole: Inhibits nucleic acid synthesis by disrupting DNA, killing H. pylori. Can cause an unpleasant metallic taste and rare central nervous system side effects like neurotoxicity.
Other Antimicrobial Drugs:Bismuth subsalicylate: Has antibacterial activity against H. pylori and stimulates prostaglandins for gastroprotective effects. Available as oral tablets. Common side effects include darkening of the tongue and teeth, and dark feces. Contraindicated in patients allergic to aspirin or taking other salicylates. Should be taken on an empty stomach.

Sucralfate:

Mechanism of Action: Sucralfate is mentioned in "Sucralfate - StatPearls" but the excerpt does not provide details on its mechanism of action or uses.

Cardiovascular Medications

The sources provide information on different classes of medications used to manage cardiovascular conditions, primarily heart failure and hypertension.

ACE Inhibitors:

Mechanism of Action: ACE inhibitors work by affecting the Renin–angiotensin–aldosterone system, a major blood pressure regulating mechanism. This system increases blood pressure by increasing salt and water retention and through angiotensin II's potent vasoconstricting effect. ACE inhibitors block the conversion of angiotensin I to angiotensin II.
Identification: ACE inhibitors are easily identifiable by their common suffix, '-pril'.
Classification: They are divided into three groups based on molecular structure:
Sulfhydryl-containing agents (e.g., Captopril, Alacepril, Zofenopril). Captopril was the first ACE inhibitor approved in the US in 1981.
Dicarboxylate-containing agents (largest group, e.g., Enalapril, Ramipril, Lisinopril). Enalapril was the first nonsulfhydryl-containing ACE inhibitor, approved in 1985.
Phosphonate-containing agents (e.g., Fosinopril).
Naturally Occurring ACE Inhibitors: Some peptides derived from dairy products, like casokinins and lactokinins, are naturally occurring ACE inhibitors. Lactotripeptides Val-Pro-Pro and Ile-Pro-Pro produced by Lactobacillus helveticushave shown ACE-inhibiting and antihypertensive functions.
Combinations: ACE inhibitors can be combined with other medications acting on the renin-angiotensin system, such as angiotensin II receptor antagonists (AIIRAs).

Angiotensin II Receptor Antagonists (AIIRAs):

Mechanism of Action: AIIRAs, also known as sartans (common suffix '-sartan'), block angiotensin II receptors.
Comparison to ACEIs in Heart Failure: The source "Angiotensin receptor blockers for heart failure - PMC - PubMed Central" compares ARBs and ACEIs for heart failure treatment. It indicates that total mortality, total hospitalizations, MI, and stroke rates did not significantly differ between ARBs and ACEIs. However, withdrawals due to adverse effects were lower with ARBs compared to ACEIs.
Combinations with ACEIs: Combining ARBs with ACEIs increased the risk of withdrawals due to adverse effects and did not reduce total mortality or hospital admissions compared to ACEI alone.
ARBs vs. Placebo in Heart Failure: In patients with LVEF >40%, ARBs did not reduce total mortality or total hospitalizations compared to placebo. Withdrawals due to adverse effects were higher with ARBs versus placebo when all patients were pooled.
Specific ARBs Mentioned: Azilsartan, Candesartan, Eprosartan, Fimasartan, Irbesartan, Losartan, Olmesartan, Tasosartan, Telmisartan, and Valsartan are listed.

Loop Diuretics:

Mechanism of Action: Loop diuretics are potent diuretics that promote profound diuresis.
Administration: They are available in IV and oral forms. Examples and their dosages include Furosemide (20, 40, 80 mg oral tablets; 10 mg/mL injectable/oral solution), Torsemide (5, 10, 20, 100 mg tablets; 10 mg/mL injectable solution), Bumetanide (0.5, 1, 2 mg tablets; 0.25 mg/mL IV solution), and Ethacrynic acid (25 mg oral tablets; 50 mg powder for injection).
Monitoring and Side Effects: Due to their potency and narrow therapeutic index, careful medical supervision and monitoring are necessary. A black box warning highlights the risk of "profound diuresis with water and electrolyte depletion" at higher dosages. Electrolyte disturbances (hyponatremia, hypochloremic alkalosis, hypokalemia, hypocalcemia, hypomagnesemia) can lead to serious cardiac arrhythmias and require periodic monitoring. Prolonged overdiuresis and dehydration can cause reversible or irreversible renal damage. They can also increase uric acid levels and have potential ototoxicity. The source "Recommended Lab Monitoring for Common Medications - Senior Care Consultant Group" recommends baseline, frequent during the first few months, and then periodic monitoring of renal function and electrolytes for loop diuretics.

Digoxin:

Medical Uses: Digoxin is a plant-derived medication used to treat irregular heartbeat (atrial fibrillation) and heart failure. It is also used in late second and third trimester abortions to cause fetal demise.
Mechanism of Action: Digoxin primarily inhibits the sodium potassium adenosine triphosphatase (Na+/K+ ATPase) in the myocardium. This leads to increased intracellular sodium and consequently increased intracellular calcium. The increased calcium enhances the contractility of the heart and affects the electrical activity, leading to a decreased heart rate.
Side Effects and Toxicity: Adverse drug reactions are common due to its narrow therapeutic index. Gynaecomastia is a potential side effect. A combination of increased atrial arrhythmogenesis and inhibited atrioventricular conduction (PAT with block) is considered diagnostic of digoxin toxicity.
Warning Signs of Toxicity: "Digoxin monitoring and toxicity management - The Pharmaceutical Journal" lists warning signs including visual disturbances (e.g., green/yellow tinge), nausea/vomiting, confusion/disorientation, heart rate <60 beats per minute, concomitant medications that alter heart rate or serum potassium, and abnormal serum potassium levels.
Monitoring: Monitoring includes checking for suspected toxicity, confirming therapeutic levels, assessing non-adherence, considering diseases or physiologic changes (renal impairment, thyroid disease), evaluating interacting drugs, and checking levels after dose changes. The therapeutic level for heart failure is 0.5 to 1 ng/mL and for atrial fibrillation is 2 ng/mL or lower. Levels should be checked at least 6 to 8 hours after a dose. It may take 15 to 20 days to reach steady-state in severe renal impairment. Concomitant use with diuretics or ACEI/ARB requires more frequent monitoring due to increased risk of digoxin intoxication.
History: Digoxin is derived from the Digitalis lanata plant (woolly foxglove).

Dopamine Antagonists (as prokinetics):

Mechanism of Action (in GI): Dopamine antagonists used as prokinetics prevent dopamine from reducing gastrointestinal movement and causing LES relaxation.
Examples (in GI): Metoclopramide and domperidone are examples of dopamine antagonists used as prokinetics.
Broader Definition: "Dopamine antagonist - Wikipedia" provides a broader definition, stating they are drugs that block dopamine receptors and are primarily used as antipsychotics for conditions like schizophrenia and bipolar disorder. They can have various side effects due to effects on different dopamine receptor subtypes and locations.
