200mg 2 tabs PRN Mg Hydroxide, Al Hydroxide (Maalox®) 1 tbsp. PRN

ADR

DRUG INTERACTION  Alcohol & metformin -causes Lactic acidosis  Ibuprofen & Aspirin - increase your risk of developing gastrointestinal ulcers and bleeding - may cause severe abdominal pain, bloating, loss of appetite, and/or black, tarry stools  Albuterol & Magnesium Hydroxide (MAALOX) - irregular heart rhythm that may be serious and potentially life-threatening: risk is increased if you have low blood levels of magnesium or potassium

ASSESMENT  PHYSIOLOGY STOMACH

Breaks down large food particles into smaller pieces so that they can be processed more easily. It is intraperitonal and located in the left epigastric regions of the abdomen. 

Hydrochloric acid -secreted from the parietal cells in the body of the stomach.

 PATHOPHYSIOLOGY

Peptic ulcer - is a circumscribed loss of the mucus membrane of the GIT system exposed to gastric juices containing acid & pepsin.  Peptic ulcer occur most common in: -esophagus -stomach*

Imbalance Of This Factors Causes Peptic Ulcer Disease:  Aggressive factors -bile, acid and pepsin  Defensive factors -mucus, bicarbonates and PG

Other contributory factors: 

Helicobacter pylori  NSAIDs  Stress  Ethanol  Tobacco

Complications of PUD 1. Bleeding - occurs in 25-30% of patients -most frequent complication and maybe life threatening - for 25% of ulcers deaths 2. Perforation -occurs in about 5% of the patients -s for 2/3 of ulcer deaths 3. Obstruction from edema or scarring

PHARMACOTHERAPHY  Misoprostol -may be used to prevent gastric ulcers caused by non-steroidal anti- inflammatory drugs.

 Consider that the interaction may be unavoidable if ibuprofen is istered more than once daily.  Avoid ibuprofen if possible or give it 2 hours after aspirin.  Consider alternative: Acetaminophen* reduces pain and lowers fevers. Unlike aspirin and other NSAIDS, acetaminophen is believed to be safe for people with ulcers.

NON-PHARMACOTHERAPY  Refer the patient to a smoking-cessation program  Stress Reduction  Avoidance of dietary irritants (Alcohol)  Physical activity can help reduce some kinds of discomfort, such as arthritis pain.
