Published Studies Related to Zantac Injection (Ranitidine Injection)
Clinical trial: intravenous pantoprazole vs. ranitidine for the prevention of peptic ulcer rebleeding: a multicentre, multinational, randomized trial. [2009.03.01]
BACKGROUND: Controlled pantoprazole data in peptic ulcer bleeding are few. AIM: To compare intravenous (IV) pantoprazole with IV ranitidine for bleeding ulcers... CONCLUSIONS: Outcomes amongst pantoprazole and ranitidine-treated patients were similar; pantoprazole provided benefits in patients with arterial spurting and gastric ulcers.
Effects of the H2-receptor antagonist ranitidine on gastric motor function after a liquid meal in healthy humans. 
CONCLUSIONS: Intravenous bolus injection of 50 mg ranitidine does not modify gastric volume or gastric emptying after a 600 mL liquid meal in healthy humans.
Continuous infusion of pantoprazole versus ranitidine for prevention of ulcer rebleeding: a U.S. multicenter randomized, double-blind study. [2006.09]
OBJECTIVES: No North American randomized study has compared ulcer rebleeding rates after endoscopic hemostasis in high-risk patients treated with high-dose intravenous (IV) proton pump inhibitors (PPIs) or IV histamine-2 receptor antagonists. Our hypothesis was that ulcer rebleeding with IV pantoprazole (PAN) would be lower than with IV ranitidine (RAN)... CONCLUSIONS: Because of the small sample size of this study, there was an arithmetic but not significant difference in ulcer rebleeding rates.
Effects of metoclopramide and ranitidine on preoperative gastric contents in day-case surgery. [2006.06.30]
This prospective, randomized, double-blinded study was performed to evaluate the effects of intravenous metoclopramide and ranitidine on preoperative gastric contents in outpatients receiving intravenous anesthesia for laparoscopic gynecologic surgery... In conclusion, intravenous prophylactic ranitidine and metoclopramide may be an easy and useful method to decrease the volume while increasing the pH of gastric contents, and therefore may reduce the number of patients at risk for aspiration pneumonitis in ambulatory laparoscopic procedures who receive an anesthesia.
Pharmacodynamic effects of 3-day intravenous treatment with pantoprazole or ranitidine after 10 days of oral ranitidine. [2005.01]
Tachyphylaxis (drug tolerance) is an undesirable condition in drug therapy with histamine-2-receptor antagonists (H2RAs).
Clinical Trials Related to Zantac Injection (Ranitidine Injection)
Effect of Ranitidine on Hyper-IgE Recurrent Infection (Job's) Syndrome [Recruiting]
This study will examine the safety and effectiveness of ranitidine (Zantac) in patients with
Hyper-IgE recurrent infection syndrome, a disease characterized by recurrent infections of
the ears, sinuses, lungs and skin, and abnormal levels of the antibody immunoglobulin E
Patients age 2 and older who have Hyper-IgE recurrent infection syndrome and who have had
chronic or frequent infections in the last 12 months may be eligible for this study.
Participants are randomly assigned to take ranitidine or placebo in pill or liquid form
twice a day for 12 months. In addition to treatment, patients undergo the following
procedures during visits scheduled on day 0 of the study (baseline) and at 3, 12, 15 and 24
months. Evaluations at 6, 9, 18 and 21 months are by telephone.
- Medical history and physical examination - baseline and 3 and 24 months.
- Clinical severity score - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months.
- Dermatology exam - baseline and 3, 12, 15 and 24 months.
- Pulmonary function test - baseline and 12 and 24 months.
- Chest CT - baseline and 12 and 24 months.
- Quality of life assessment - baseline and 3, 12, 15 and 24 months.
- Pregnancy testing - baseline and 3, 12, 15 and 24 months.
- HIV test - baseline and 12 and 24 months.
- Contraception evaluation - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months.
- Missed school/work days assessment - baseline and 3, 12, 15 and 24 months.
- Medication adherence - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months.
In addition to the above procedures, participants who are not enrolled in study 00-I-0159
have a baseline scoliosis series and genetic consult....
Comparison of Pantoprazole and Ranitidine in Dyspepsia [Recruiting]
The H0 hypothesis of the study there is no difference between pantoprazole and ranitidine in
treating patients presented with dyspepsia to the emergency deparment.
The H1 hypothesis is there is difference between pantoprazole and ranitidine in treating
patients presented with dyspepsia to the emergency department.
A Study to Evaluate The Effects of Two Different Meal Types, Omeprazole And Ranitidine On Danoprevir Pharmacokinetics When Coadministered With Ritonavir in Healthy Volunteers [Recruiting]
This randomized, open-label study will evaluate the effect of food, and the effect of
omeprazole and ranitidine on danoprevir co-administered with ritonavir. Volunteers will be
assigned to one of two treatment groups. Volunteers in both groups will receive oral doses
of danoprevir and ritonavir. In addition, volunteers in group 2 will receive oral doses of
omeprazole and ranitidine. The anticipated time of the study is approximately 6 weeks.
A Comparative Efficacy and Safety Study of Nexium Delayed-Release Capsules (40mg qd and 20mg qd) Versus Ranitidine 150mg Bid for the Healing of NSAID-Associated Gastric Ulcers When Daily NSAID Use is Continued [Completed]
Nonsteroidal anti-inflammatory drugs (NSAIDS) are often associated with gastric ulcers. This
study looks at the treatment of these gastric ulcers with one of the three following
treatment groups: esomeprazole 40 mg once daily; esomeprazole 20 mg once daily; or ranitidine
150 mg twice daily.
A Study To Investigate The Effectiveness Of AH234844 (Lavoltidine) Compared With NEXIUM And Ranitidine. [Completed]
Current treatment for gastroesophageal reflux disease (GERD) confirms an unmet need in
patients, based on slow onset of action and an inability to provide 24-hour gastric-acid
suppression. Clinical data on AH234844 demonstrates a rapid onset of action, high potency,
and prolonged duration of effect. The present study endeavors, in part, to compare
lavoltidine to two GERD drugs, NEXIUM and ranitidine.
