Slide 1

Drugs that influence the Urinary System NURS 1950: Pharmacology

Slide 5

Diuretics work in the kidney at different locales of the nephron Can meddle with the activity of aldosterone bringing about loss of sodium Where goes sodium, so goes water

Slide 8

What happens with diuretics Decrease abundance water Loop diuretics + 0.9% NaCl = loss of calcium Decrease overabundance NaCl Decrease cerebral edema (Mannitol) Decrease expanded IOP (Diamox)

Slide 9

Mannitol is an osmotic diuretic (a sugar); in the mind, its nearness causes water to be attracted to it Works a similar route in the eye: the overabundance intraocular liquid is attracted to the mannitol in the hyperosmotic plasma

Slide 10

Carbonic anhydrase inhibitor Diamox exceptionally powerless diuretic Useful in treating glaucoma

Slide 11

Methylxanthines Aminophylline Theophylline Caffeine Theobromine Diuretic impact from enhanced blood stream to kidney Generally not utilized for diuretic impact

Slide 12

Obj. 9 Thiazides Action of the thiazides Act on the distal tubules of the kidney Block reabsorption of sodium and chloride particles from the tubule The unreabsorbed Na and Cl particles go into the gathering channels, bringing water with them Thiazides have antihypertensive properties due to direct vasodilation impact on fringe arterioles Expected results from treatment Decreased edema and change of manifestations RT overabundance liquid collection Reduction in BP

Slide 13

Thiazides Assessments Mental status Diabetics require benchmark blood glucose Assess listening to Assess for side effects of intense gout SE to expect: orthostatic hypotension Usually in beginning phases of treatment Teach customer security measures

Slide 14

Thiazides SE to report GI disturbance, N/V, stoppage Electrolyte lopsidedness, lack of hydration Hyperuricemia Hyperglycemia Hives, rash Thiazides can interface with Digoxin, corticosteroids Lithium, NSAIDs Oral hypoglycemic operators

Slide 15

Thiazides can collaborate with Digoxin, corticosteroids Lithium, NSAIDs Oral hypoglycemic specialists

Slide 16

Thiazide and Thiazide-like Drugs Thiazide diuretics incorporate Bendroflumethiazide (Naturetin) Chlorothiazide (Diuril) Hydrochlorothiazide (HCTZ) {Esidrix, HydroDiuril} Polythiazide (Renese) Trichlomethiazide (Naqua, Metahydrin, Diurese)

Slide 17

Thiazide-like medications incorporate Chlorthalidone (Hygroton) Indapamide (Lozol) Metolazone (Zaroxolyn)

Slide 18

Objective 8: depict the utilizations, activities, and unfavorable impacts of the thiazide and thiazide - like diuretics Drugs that influence the circle of Henle Bumetanide (Bumex) Ethacrynic corrosive (Edecrin) Furosemide (Lasix) Torsemide (Demadex)

Slide 19

Loop Diuretics Act on the up and up of Henle in the kidney Inhibits Na and Cl reabsorption Some expansion blood stream to glomeruli Inhibits electrolyte retention in proximal tubule Lose sodium, chloride, potassium, magnesium, sodium bicarbonate

Slide 20

Loop Diuretics Onset of diuretic impact fluctuates, yet is inside 1-2 hours. IV, drugs work inside 5-10 minutes Peak impact inside 1-2 hours Duration around 6 hours

Slide 21

Loop Diuretics Maximum mg/day Bumex 10 mg for every 24 hours Edecrin 400 mg for each 24 hours Lasix 1000 mg/24 hours Cross sensitivities Sulfonamides and Lasix, Demadex SE to expect Oral disturbance Dry mouth Orthostatic hypotension

Slide 22

Loop Diuretics SE to report with circle diuretics GI aggravation, stomach torment Electrolyte irregularity, drying out Hives, pruritus, rash Some can bring about loss of hearing and hyperglycemia (meddle with hypoglycemic specialists)

Slide 23

Loop Diuretics Drug communications Alcohol, barbiturates, opiates Aminoglycosides Cisplatin NSAIDs Corticosteroids Probenecid Digoxin

Slide 24

Loop Diuretics Loop diuretics incorporate Bumetanide (Bumex) Ethacrynic corrosive (Edecrin) Furosemide (Lasix) Torsemide (Demadex)

Slide 25

Objective 11: list the electrolyte lopsidedness that most generally happens as an aftereffect of diuretic treatment Why is there worry about the electrolyte adjust?

Slide 26

Obj. 12 Potassium-Sparing Diuretics Weak antihypertensives Mechanism of activity obscure Do work in distal renal tubule Retains potassium Excretes sodium Some have against aldosterone movement

Slide 27

Potassium Sparing diuretics Maximum dosing per 24 hrs medicate subordinate SE to expect with Midamor: anorexia, N/V, fart and HA SE to report: electrolyte irregularity, drying out ,

Slide 28

Potassium Sparing diuretics SE to expect and report with Aldactone and Dyrenium: mental disarray, HA, looseness of the bowels, electrolyte unevenness, parchedness, gynecomastia, lessened moxie, bosom delicacy Dyrenium can likewise bring about unfavorably susceptible response (hives, pruritus, rash)

Slide 29

Potassium Sparing diuretics Generally, tranquilize collaborations for the K+ saving specialists Lithium, ACE inhibitors, salt substitutes, K+ substitution NSAIDs, Potassium-saving medications incorporate Amiloride (Midamor) Spironolactone (Aldactone) Triamterene (Dyrenium)

Slide 30

Potassium Sparing diuretics Potassium-saving medications incorporate Amiloride (Midamor) Spironolactone (Aldactone) Triamterene (Dyrenium)

Slide 31

Objective 13: clarify how expanded liquid admission improves the activity of diuretics Why is a sufficient liquid admission vital with diuretic treatment? On the off chance that the customer needs to get up amid the night to void, what will they most likely do?

Slide 32

Objective 14: list great dietary wellsprings of potassium What are some great dietary wellsprings of potassium? In the event that a customer is on Aldactone, what might you inform them concerning high potassium sustenances?

Slide 33

Obj. 15 Nursing Implications: Diuretics Assessments to make Teaching to include:

Slide 34

Obj. 16 Drugs for UTI Drugs incorporate Antibiotics Fosfomycin (Monurol) Quinolones : cinoxacin, nalidixic corrosive, norfloxacin Methenamine madelate Nitrofurantoin

Slide 35

Fosfomycin ( Monurol ) Inhibits bacterial cell divider amalgamation Reduces adherence of microscopic organisms to epithelial cells of urinary tract Single dosage treatment SE to expect: queasiness, looseness of the bowels, stomach spasms, fart SE to report: perineal copying, dysuria Indicates UTI is not reacting to treatment Drug associations Drugs, for example, metoclopramide that expansion GI motility

Slide 36

Quinolones Norfloxacin ( Noroxin ) has extensive variety of movement against gram negative and gram positive microbes Expensive Reserve for safe/repetitive diseases SE to report Hematuria as precious stones can frame in urinary tract HA, tinnitus, dazedness, shivering sensations, photophobia Various medication communications can happen Assess customer's ebb and flow tranquilize treatment, monograph of quinolone being utilized

Slide 37

Methenamine mandelate (Mandelamine) Converts to alkali and formaldehyde in acidic pee Used in customers powerless to interminable, intermittent UTIs Preexisting contaminations treated with anti-infection agents Implementation DO NOT pound the tablets pH testing of pee: report more than 5.5 SE to expect N/V, burping SE to report Hives, pruritus , rash Bladder disturbance, dysuria, recurrence Drug connections Acetazolamide, sodium bicarbonate Sulfamethizole
