| Tums/calcium salts | sodium bicarbonate, antacid, goal is to raise stomach pH to min 3.5, act quickly/short duration/ do not promote ulcer healing, SE: constipation/diarrhea, acid rebound |
| Antacids-Nursing Interventions | take at least 2hrs before other PO meds, 1hr before meals/at least 2hrs after meals, may decrease absorption of efficacy of other meds-tetracycline’s, seek medical attn. if sx persist or recur, don’t take w/ iron |
| Helicobacter pylori | gram – bacteria, usually cause of peptic ulcer disease, Tx: two antibiotics, PPI, bismuth subsalicylate/Pepto-Bismol |
| Pepcid/famotidine | histamine-2 antagonist, help heal ulcer in 4-8wks, suppress gastric acid secretion, begin to work w/in hr, for up to 12hrs so take BID, absorption not affected by food intake |
| Prilosec/omeprazole | PPI, help heal ulcer in 4-8wks, suppress gastric acid secretion, delayed onset of action but last 24hrs w/ effects up to 3days, except for Previcid Not recommended for <18yo, ^risk for C-diff, used w/ other meds for tx of helicobacter pylori |
| H2-Receptor Antagonists and PPI-Nursing Interventions | freq used prevent/prophylaxis stress ulcers in ICU/critically ill pts, block release hydrochloric acid response to gastrin, H2-receptors located parietal cells/stomach, long-term use ^risk C-diff, used in combo w/ other meds tx of helicobacter pylori |
| Laxatives | should be used for short term relief of constipation & to prevent straining when clinically undesirable, routinely avoid constipation first by proper diet, fluid intake & exercise, desire is to avoid lazy gut/bowel syndrome |
| Constipation | the state in which an individual experiences stasis of the large intestine resulting in infrequent elimination and/or hard/dry feces |
| Dulcolax/bisacodyl | chemical stimulants, castor oil, senna/senokot |
| MiraLax/polyethylene glycol | bulk/osmotic stimulants, ^ the motility of the GI tract by ^ the fluid in the intestinal contents, which enlarges bulk, stimulates local stretch receptors, and activates local activity |
| Colace/Surfak/docusate sodium | lubricants, reduce surface tension of feces allowing water and fat penetration leading to a softer stool, to prevent straining in post-op, post-MI, and post-partum |
| Constipation-Nursing Interventions | monitor number and type of stools, diet-fiber/bulk & adequate liquid intake, privacy, establish reg time for elimination, ID what helps individual produce stool, emphasize need for reg exercise, know what is norm for individual |
| Phenergan/promethazine | phenothiazine, SE: anticholinergic, sedating, nasty to tissue-must be diluted, given slowly, check IV patency |
| Reglan/metoclopramide | nonphenothiazine/GI stim/prokinetic agents, ^mvmnt GI content prevent N/V, heartburn, persistent fullness after meals, anorexia,tx N/V SP surg, cancer chemo, not sedating,IV PO, SE: drowsiness, not for coma/severe CNS depression/those w/ recent brain inj |

| Antihistamine-Second Generation | loratatdine/Claritin, less sedation |
| Antitussives | suppress cough reflex acting centrally to suppress medullary cough center/locally as anesthetic/to ^secretion and buffer irritation,cause CNS depression inc drowsiness/sedation, used w/ caution in situation which coughing important for clearing airways |
| Unproductive Cough w/ Need for Expectoration | guaifenesin/Mucinex/Robitussin, reduces adhesiveness of and liquefies lower respiratory tract secretions, SE: GI symptoms |
| Robitussin DM | dextromethorphan, combination drug, antitussive, cough suppressant and expectorant |
| Expectorant | cough less but effectively, liquefies lower respiratory tract making it easier to cough out secretions |
| Thick Secretions-Mucolytic | acetylcysteine/Mucomyst, generally reserved individ have most diff coughing up secret(COPD, cystic fibrosis, pneumonia,TB), protects liver after acetaminophen OD, NGtD prevent radiocontrast-induced renal dysfun-protects kidneys, SE:GI upset, smell/sulfur |
| Topical Steroid Nasal Medication | fluticasone/Flovent/Flonase/Advair-decongest, preferred patients who need to avoid systemic adrenergic effects associated w/ oral decongestants, prevention of bronchospasm, tx for asthma for pts w/ asthma who do not respond to trad bronchodilators |
