Forty patients diagnosed with a major depressive disorder for which ECT was indicated as a treatment for their current episode were randomly allocated to either the memantine (5mg/day) group or the placebo group. All patients underwent the same protocol for anaesthesia and ECT procedures. The patients received memantine or the placebo for the whole period of ECT treatment, starting the day before ECT and continuing until the fourth session of ECT. The Modified Mental State Examination (MMSE) was used for the assessment of cognition before and after the trial. Regarding MMSE and item 3 MMSE (related to recent memory), the memantine group scored significantly higher at the end of ECT sessions than the control group (P=0.02, P<0.001, respectively). Our data support the hypothesis that memantine may reduce cognitive impairment following...

Zinc supplementation in addition to antiviral therapy of chronic hepatitis C has been accompanied by some success in patients with chronic hepatitis C. The aim of the present pilot study is to determine the effect of 30 mg elemental zinc on biochemical and virological response in a population of patients with chronic hepatitis C with beta thalassemia major. A prospective, double blind,placebo controlled trial included 40 patients being treated with Pegylated interferon Alfa (Peg IFN-α) and ribavirin. Biochemical and virological parameters and plasma zinc levels were determined before starting treatment. Patients were randomly selected to receive either zinc or a placebo in addition to Peg IFN-α and ribavirin for a period of one year. AST, ALT, sustained viral response (SVR), and zinc levels were measured after treatment.Of the original 40 eligible patients, eight withdrawn from the study ...

Curcuminoids are natural products with anti-atherosclerotic and lipid-modifying effects but their efficacy in patients with MS has not yet been tested. To investigate the effects of bioavailability-enhanced curcuminoids, as adjunctive to standard of care, on serum lipid concentrations in patients with MS. Patients diagnosed with MS according to the NCEP-ATPIII criteria who were receiving standard of care were assigned to either curcuminoids (C3 complex(®); 1000 mg/day; n=50) or placebo (n=50; matched with drug capsules in shape and color) for 8 weeks. In order to improve the oral bioavailability, curcuminoids were co-administered with piperine (bioperine(®)) in a ratio of 100:1. Serum concentrations of total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, small den...

This study was designed to assess the incidence of potential drug interactions (PDI) and rank their clinical value in post coronary care unit (Post-CCU) of a teaching hospital in Tehran, Iran. In this prospective study, three pharmacists with supervision of a clinical pharmacist actively gathered necessary information for detection of DDIs. Data were tabulated according to the combinations of drugs in treatment chart. Verification of potential drug interactions was carried out using the online Lexi-Interact™ 2011. A total of 203 patients (113 males and 90 females) were enrolled in the study. The mean age of patients was 61 ± 12.55 years (range = 26-93). A total of 90 drugs were prescribed to 203 patients and most prescribed drugs were atorvastatin, clopidogrel and metoprolol. Mean of drugs was 11.22 per patient. A total of 3166 potential drug interactions have been identified by Lexi- ...

This study was designed as prospective cross-sectional evaluations by direct unconcealed observation in a setting consisted of orthopedic, general surgery and gastroenterology wards of a teaching hospital. Participants were those patients hospitalized in these wards along with nurses responsible for preparation and administration of IV medications. Medication errors occurred in the process of preparation and administration of IV drugs, were recorded by a pharmacist. The frequency of medication errors with suggesting a solution to overcome was the main outcome of this study. Details of the preparation and administration stages of the observed drugs were compared to an instructed checklist prepared by an expert clinical pharmacist. From a total of 357 preparation and administration episodes, the most common type of error (%20.6) was th...

Inadequate knowledge of nurses has been reported as a cause of such errors. We aimed to evaluate the role of nurses' education via installation of wall posters and giving informative pamphlets in reducing the errors in preparation and administration of intravenous drugs in 2 wards (ICU and surgery) of a teaching hospital in Tehran, Iran. A trained observer stationed in 2 wards in different work shifts. He recorded the nurses' practice regarding the preparation and administration of IV drugs and scored them before and after the education process. 400 observations were evaluated. Of them, 200 were related to before education and 200 were related to after education. On a 0-10 quality scale, mean ± SD scores of before and after education were determined. Mean ± SD scores of before and after education at the 2 wards were 4.51 (± 1.24) and 6.15 (± 1.23) respectively. There w...

Furthermore, it has been reported that the administration of zinc has an important role in pharmacotherapy of viral hepatitis. Cirrhotic patients with decrease in plasma zinc level have been covered in previous studies. It is seemingly necessary to assess the zinc level, in Iranian cirrhotic patients, as a distinct population, Because of the large phytate amounts in Iranians diet. Regarding to etiology, disease progress, and treatment, there are some differences in the 2 most common causes of cirrhosis in the Iranian population (hepatitis B and hepatitis C) and it is possible that the zinc level may be different between the two. This study was done to shadow some lights on the subject. Between April 2008 and November 2008, plasma zinc level was determined, by atomic absorption method, in 60 cirrhotic inpatients treated due to hepatitis B or hepatitis C in Talighani hospital (a referral center for gastro...

Thus, its pharmacological treatment should be regarded. The purpose of this study was to compare the efficacy of morphine, fentanyl and pethidine for the treatment of postanesthesia shivering. Fifty patients who developed shivering were treated in a randomized double blinded manner with an intravenous bolus dose of 2 or 4 mg morphine, 25 or 50 mg pethidine, and 50 μg fentanyl. Then, they were monitored for 30 minutes and the shivering suppression grade, the time taken to stop shivering, the shivering cessation time, recurrence of shivering and opioid side effects were evaluated. Core body temperature was measured immediately before, and at 15 and 30 minute after administering the drug. The groups did not differ significantly regarding shivering suppression grade, shivering cessation time, and recurrence of shive...

The eradication of H. pylori has been recommended for the treatment of different gastrointestinal diseases. Notwithstanding, a combination therapy is needed for Helicobacter pylori eradication, but using these medications can be the cause, the incidence risk of patients' adherence to treatment regimens reduction and probably increase risk of Adverse Drug Reactions (ADRS), so, it is seem that evaluation the out come of combination therapy is need more than the past. The aim of present study was to determine the patients' adherence to the treatment and the ADRs with five eradiation regimens. A cross sectional study was done in a well known referral clinic of gastrointestinal disorders in Tehran, Iran. Ninety patients were evaluated the study (18 in each of the five regimens). The adherence to the treatment and the ADRs of the patients were asked during the treatment, twice, by doing telephone assays. The...

The objective of present study is to evaluate the effect of co-administration of omeprazole 20 mg/d plus sustained Release baclofen (SR baclofen) vs. omeprazole 20 mg/d plus placebo on alleviation of symptoms in patients with a diagnosis of GERD. A prospective, double blind, placebo controlled trial included 60 patients with diagnosis of GERD have been done. Patients were randomly selected to receive either SR baclofen or a placebo in addition to omeprazole 20 mg/d for a period of 2 weeks. Patients were questioned regarding heartburn, regurgitation, chest pain and hoarseness at the base line and after 2 weeks. All patients tolerated the medications and no patients failed to complete the study due to adverse drug reactions. A total of 53 patients completed the study, 25 in SR baclofen and 28 in placebo group. After 2 weeks, 1 patient (4%) in SR baclofen group reported ...
