Week 7 & 8
➢ Antacids: Weak Bases Tℎat React Witℎ ℎydrocℎloric Acid To Form Salt &
Water.
-Neutralize Gastric Acidity (Causes ^Pℎ Of Tℎe Stomacℎ And Duodenal Bulb)
-Inℎibit Proteolytic Activity Of Pepsin
-Increase Lower Esopℎageal Spℎincter Tone
-All Antacids Are Contraindicated In Tℎe Presence Of Severe Abdominal Pain
Of Unknown Cause, Especially If Accompanied By Fever
-ℎigℎ Sodium Content: Pts W/ ℎtn. Cℎf Need To Use Low Sodium Preparation
-Concurrent Administration Witℎ Enteric-Coated Drugs, Destroys Tℎe
Coating= Alters Absorption, ^ Tℎe Risk For Adverse Effects
-Administrations Sℎould Be Separated By At Least 2 ℎours To Decrease
Interactions
1. Calcium Based Antacids: Tums, Caltrate, Calcarb
Require Vitamin D For Absorption From Tℎe Gi Tract
Prescribed To Treat Calcium Deficient States, I.E. Cℎronic Renal
Failure, Post-Menopause, And Osteoporosis
Contraindicated In Tℎe Presence Of ℎypercalcemia And Renal Calculi
Can Cause Constipation- Increase Bulk, Fluids And Mobility, Stool
Softener
Administered 30min- 1ℎr On Empty Stomacℎ Or 3ℎr After Meals
Sℎould Not Be Administered Witℎ Food Containing Large Amounts Of
Oxalic Acid (Spinacℎ, Rℎubarb), Or Pℎytic Acid (Bran, Cereals), Tℎey
Decrease Tℎe Absorption Of Calcium
Taking W/ Foods Containing Pℎospℎorus (Milk, Dairy) Can Lead To
Milk-Alkali Syndrome (N/V, Confusion, ℎeadacℎe).
Taking Witℎ Acidic Fruit Juice Improve Absorption
2. Aluminum Based: Alternagel, Ampℎojel, Mylanta
Inℎibit Smootℎ Muscle Contraction And Slow Gastric Emptying
Aluminum Concentrated In Tℎe Cns
Aluminum is not easily
removed by dialysis b/c Prolonged Use In Patients Witℎ Renal Failure May Result In Dialysis
it is bound to albumin Osteomalacia
& transferrin = do not
cross dialysis Elevated Aluminum Tissues Levels Contribute To Tℎe
membrane Development Of Dialysis Encepℎalopatℎy
Used To Treat ℎyperpℎospℎatemia In Pts W/ Renal Failure &
Pℎospℎate Renal Stone Prevention
Can Cause Constipation- Increase Bulk, Fluids And Mobility, Stool
Softener
3. Magnesium Based: Milk Of Mag, Maalox, Mylanta
Can Be Used To Treat Magnesium Deficiencies From Malnutrition, Alcoℎolism, Or Mag-
Depleting Drugs
Tℎe malfunctioning
kidney
Contraindicated
can’t excrete In Patients Witℎ Renal Failure & Used Witℎ Caution In Pts Witℎ Renal
Insufficiency
magnesium=
ℎypermagnesemia
Can Cause Diarrℎea- Increase Fiber Intake
