DrugDrug NameDrug Indication
DB00213Pantoprazole **Pantoprazole Injection**: **Treatment of gastroesophageal reflux disease associated with a history of erosive esophagitis** Pantoprazole for injection is indicated for short-term treatment (7-10 days) of patients having gastroesophageal reflux disease (GERD) with a history of erosive esophagitis, as an alternative to oral medication in patients who are unable to continue taking pantoprazole delayed-release tablets. _Safety and efficacy of pantoprazole injection as the initial treatment of patients having GERD with a history of erosive esophagitis have not been demonstrated at this time_.[FDA label] **Pathological Hypersecretion Associated with Zollinger-Ellison Syndrome** Pantoprazole for injection is indicated for the treatment of pathological hypersecretory conditions associated with Zollinger-Ellison Syndrome or other neoplastic conditions.[FDA label] **Pantoprazole delayed-release oral suspension**: **Short-Term Treatment of erosive esophagitis associated with gastroesophageal reflux disease (GERD)** Indicated in adults and pediatric patients five years of age and above for the short-term treatment (up to 8 weeks) in the healing and symptomatic relief of erosive esophagitis. For adult patients who have not healed after 8 weeks of treatment, an additional 8-week course of pantoprazole may be considered. Safety of treatment beyond 8 weeks in pediatric patients has not been determined.[F3202] **Maintenance of healing of erosive esophagitis** Indicated for maintenance of healing of erosive esophagitis and reduction in relapse rates of daytime and nighttime heartburn symptoms in adult patients with GERD.[F3202] **Pathological hypersecretory conditions including Zollinger-Ellison syndrome** Indicated for the long-term treatment of the above conditions.[F3202]
DB00338OmeprazoleOmeprazole, according to the FDA label [FDA label] is a proton pump inhibitor (PPI) used for the following purposes: • Treatment of active duodenal ulcer in adults • Eradication of Helicobacter pylori to reduce the risk of duodenal ulcer recurrence in adults • Treatment of active benign gastric ulcer in adults • Treatment of symptomatic gastroesophageal reflux disease (GERD) in patients 1 year of age and older • Treatment of erosive esophagitis (EE) due to acid-mediated GERD in patients 1 month of age and older • Maintenance of healing of EE due to acid-mediated GERD in patients 1 year of age and older • Pathologic hypersecretory conditions in adults
DB00448LansoprazoleLansoprazole is used to reduce gastric acid secretion and is approved for short term treatment of active gastric ulcers, active duodenal ulcers, erosive reflux oesophagitis, symptomatic gastroesophageal reflux disease, and non-steroidal anti-inflammatory drug (NSAID) induced gastric and duodenal ulcers. [A4892][A177065][FDA Label] It may be used in the maintenance and healing of several gastric conditions including duodenal ulcers, NSAID related gastric ulcers, and erosive esophagitis.[FDA Label] Lansoprazole prevents recurrence of gastric ulcers in patients who have a documented history of gastric ulcers who also use NSAIDs chronically. [FDA Label] Predictably, it is also useful in the management of hypersecretory conditions including Zollinger-Ellison syndrome. [FDA Label] Lansoprazole is effective at eradicating H. pylori when used in conjunction with amoxicillin and clarithromycin (triple therapy) or with amoxicillin alone (dual therapy). [FDA Label]
DB00736EsomeprazoleEsomeprazole is indicated for the treatment of acid-reflux disorders including healing and maintenance of erosive esophagitis, and symptomatic gastroesophageal reflux disease (GERD), peptic ulcer disease, H. pylori eradication, prevention of gastrointestinal bleeds with NSAID use, and for the long-term treatment of pathological hypersecretory conditions including Zollinger-Ellison Syndrome.
DB01129RabeprazoleFor the treatment of acid-reflux disorders (GERD), peptic ulcer disease, H. pylori eradication, and prevention of gastroinetestinal bleeds with NSAID use.
DB05351DexlansoprazoleDexlansoprazole is indicated for healing all grades of erosive esophagitis (EE), maintaining and healing of EE and relief of heartburn, and treating heartburn associated with symptomatic non-erosive gastroesophageal reflux disease (GERD).
DB13762DexrabeprazoleNot Available
DB00501CimetidineFor the treatment and the management of acid-reflux disorders (GERD), peptic ulcer disease, heartburn, and acid indigestion.

DB00927FamotidineFor the treatment of peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD).
DB01142DoxepinOral doxepin is approved for the following indications: - Treatment of depression and/or anxiety.[A177163] - Treatment of depression and/or anxiety associated with different conditions, including alcoholism, organic disease and manic-depressive disorders.[T249] - Treatment of psychotic depressive disorders with associated anxiety.[T249] - Treatment of involutional depression.[T249] - Treatment of manic-depressive disorder.[T249] - Treatment of insomnia characterized by difficulties with sleep maintenance.[A177163] Topical doxepin is also approved for short-term (up to 8 days) management of moderate pruritus in adult patients with atopic dermatitis, pruritus or lichen simplex chronicus.[T249] Off-label, doxepin is used topically for the management of neuropathic pain.[A177172] Depression is a common medical illness that causes feelings of sadness and or loss of interest in prior enjoyable activities. This condition can lead to emotional and physical disturbances that can decrease the ability of a person to function in a regular environment.[L5980] Anxiety is a normal reaction of the body towards a normal danger. When the anxious state is exacerbated or appears on situations without danger, it is defined as an anxiety disorder. This disorders can appear in different forms such as phobias, panic, obsessive-compulsive disorder and post-traumatic stress disorder.[L5983] Insomnia is a sleep disorder that directly affects the quality of life of the individual. It is characterized by the complication either to fall asleep or to stay asleep. This condition can be occasional or chronic.[L5986] Pruritus is defined as an unpleasant skin reaction that provokes the urge to scratch. It can be localized or generalized and it can appear in an acute or chronic manner.[L5989] Neuropathic pain occurs due to the damage or dysfunction of the peripheral or central nervous system rather than stimulation of the pain receptors.[L5992]
