CCBs function by inhibiting the movement of calcium across the cell membranes of cardiac and arterial muscles, leading to vasodilation and reduced myocardial workload. Key indications include hypertension, angina pectoris, and vasospastic angina. Contraindications are severe conditions such as sick sinus syndrome, heart block, severe ventricular dysfunction, and cardiogenic shock. Adverse effects span multiple systems, including dizziness, fatigue, peripheral edema, hypotension, gingival hyperplasia, and flushing. Nursing interventions emphasize frequent monitoring of blood pressure, pulse, fluid balance, and signs of heart failure, along with careful assessment of anginal pain. Patients should also be advised to avoid excessive grapefruit juice consumption and to monitor their pulse. Significant interactions exist with cimetidine, theophylline, digoxin, and rifampin, requiring careful management to prevent altered efficacy or toxicity. The document serves as a vital resource for healthcare professionals.","","cbCaibq9tRrDaYlG","https://ap.wps.com/l/cbCaibq9tRrDaYlG","pdf",591585,1,"English","en",105,"Calcium Channel Blockers | PDF",1778276017,3,{"code":4,"msg":28,"data":29},"ok",{"site_id":23,"language":22,"slug":30,"title":13,"keywords":15,"description":14,"schema_data":31,"social_meta":64,"head_meta":66,"extra_data":68,"updated_unix":25},"calcium-channel-blockers",{"@graph":32,"@context":63},[33,49],{"@type":34,"itemListElement":35},"BreadcrumbList",[36,40,44,46],{"item":37,"name":38,"@type":39,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":41,"name":42,"@type":39,"position":43},"https://docshare.wps.com/document/","Document",2,{"item":45,"name":12,"@type":39,"position":26},"https://docshare.wps.com/document/healthcare/",{"item":47,"name":13,"@type":39,"position":48},"https://docshare.wps.com/document/calcium-channel-blockers/27684",4,{"url":47,"name":13,"@type":50,"author":51,"headline":13,"publisher":53,"fileFormat":56,"description":14,"dateModified":57,"datePublished":57,"encodingFormat":56,"isAccessibleForFree":58,"interactionStatistic":59},"DigitalDocument",{"name":9,"@type":52},"Person",{"url":37,"name":54,"@type":55},"DocShare","Organization","application/pdf","2026-05-08",true,{"@type":60,"interactionType":61,"userInteractionCount":4},"InteractionCounter",{"@type":62},"ViewAction","https://schema.org",{"og:url":47,"og:type":65,"og:title":13,"og:site_name":54,"og:description":14},"article",{"robots":67,"canonical":47},"index,follow",{"doc_id":7,"site_id":23},{"code":4,"msg":5,"data":70},[71,75,79,83,88,93,96,101,106,109,113],{"id":20,"doc_module":4,"doc_module_name":42,"category_name":72,"show_sort_weight":73,"slug":74},"Story & Novel",90,"story-novel",{"id":43,"doc_module":4,"doc_module_name":42,"category_name":76,"show_sort_weight":77,"slug":78},"Literature",80,"literature",{"id":48,"doc_module":4,"doc_module_name":42,"category_name":80,"show_sort_weight":81,"slug":82},"Exam",70,"exam",{"id":84,"doc_module":4,"doc_module_name":42,"category_name":85,"show_sort_weight":86,"slug":87},5,"Comic",60,"comic",{"id":89,"doc_module":4,"doc_module_name":42,"category_name":90,"show_sort_weight":91,"slug":92},6,"Technology",50,"technology",{"id":11,"doc_module":4,"doc_module_name":42,"category_name":12,"show_sort_weight":94,"slug":95},40,"healthcare",{"id":97,"doc_module":4,"doc_module_name":42,"category_name":98,"show_sort_weight":99,"slug":100},8,"Research & Report",30,"research-report",{"id":102,"doc_module":4,"doc_module_name":42,"category_name":103,"show_sort_weight":104,"slug":105},9,"Religion & Spirituality",20,"religion-spirituality",{"id":104,"doc_module":4,"doc_module_name":42,"category_name":107,"show_sort_weight":104,"slug":108},"World Cup","world-cup",{"id":110,"doc_module":4,"doc_module_name":42,"category_name":111,"show_sort_weight":110,"slug":112},10,"Lifestyle","lifestyle",{"id":114,"doc_module":4,"doc_module_name":42,"category_name":115,"show_sort_weight":84,"slug":116},19,"General","general"]
