ACTIVE LEARNING TEMPLATE: Medication STUDENT NAME _____________________________________ Losartan MEDICATION __________________________________________________________________________ Antihypertensives CATEGORY CLASS ______________________________________________________________________ REVIEW MODULE CHAPTER ___________ PURPOSE OF MEDICATION Expected Pharmacological Action Inhibits vasoconstrictive and aldosterone-secreting action of angiotensin II by blocking angiotensin II receptor on the surface of vascular smooth muscle and other tissue cells. Therapeutic Use Lowering of BP in hypertensive patients.Decreased progression of diabetic nephropathy.Decreased incidence of stroke in patients with hypertension and left ventricular hypertrophy Complications CNS: dizziness, asthenia, fatigue, headache, insomnia. CV: edema, chest pain. EENT: nasal congestion, sinusitis, pharyngitis, sinus disorder. GI: abdominal pain, nausea, diarrhea, dyspepsia. Musculoskeletal: muscle cramps, myalgia, back or leg pain. Respiratory: cough, URI. Other: angioedema. Contraindications/Precautions Contraindicated in patients hypersensitive to drug. Use cautiously in patients with impaired renal or hepatic function. Dialyzable drug: No. Overdose S&S: Hypotension, tachycardia, bradycardia. Interactions Drug-herb. Ma huang: May decrease antihypertensive effects. Discourage use together. Drug-food. Salt substitutes containing potassium: May cause hyperkalemia. Monitor patient closely. Medication Administration Tablets: 25 mg, 50 mg, 100 mg Nursing Interventions Drug can be used alone or with other antihypertensives. Monitor patients who are also taking diuretics for symptomatic hypotension. Regularly assess patient's renal function (via creatinine and BUN levels). Patients with severe HF whose renal function depends on the angiotensin-aldosterone system may develop acute renal failure during therapy. Closely monitor patient's BP, renal function, and potassium levels, especially during first few weeks of therapy and after dosage adjustments. Client Education Evaluation of Medication Effectiveness Decrease in BP without appearance of excessive side effects.Delayed progression of diabetic nephropathy in patients with type 2 diabetes.Decreased incidence of stroke in patients with hypertension and left ventricular hypertrophy ACTIVE LEARNING TEMPLATES Tell patient to avoid salt substitutes; these products may contain potassium, which can cause high potassium level in patients taking losartan. Advise patient not to breastfeed while taking drug. Advise patient to report all adverse reactions and to immediately report swelling of face, eyes, lips, or tongue or breathing difficulty.
