A 45-year-old store manager complained of a burning, gnawing pain, moderately severe, almost always in the epigastric region. The pain is absent when he awakens, appears in mid-morning, and is relieved by food but recurs two to three hours after a meal. The pain often awakens him at 1 or 2 am. An endoscopic examination and x-ray studies with barium showed normal stomach function but the presence of duodenal ulcers . Gastric analysis demonstrated that the gastric juice pH fell to 1.9 with pentagastrin stimulation (6 ug/kg s.c.). Fasting serum gastrin levels were normal. Recommended treatments for this individual are: Antacids: 15 - 30 mL of liquid or two to four tablets one to three hours after each meal and at bedtime for six weeks Histamine (H2) receptor antagonists: cimetadine (300 mg) or ranitidine (150 mg) with each meal and at bedtime for four to eight weeks. What is the prognosis is the patient follows the recommended treatment plan?
