Self-assumed Neurologic Related Condition Deviated Metoclopramide-Induced Acute Dystonic of Oculogyric Crisis in a Woman of Childbearing Age: A Case Report

A 26-year-old Malaysian woman (childbearing age) attended a private primary care clinic with a known case of gastroesophageal reflux disease (GERD) and complained of persistent nausea and a few episodes of vomiting. She had no known drug allergy, no surgical history, no hospitalization in the last two years, was a non-smoker, and no history of drug or alcohol abuse. The patient was prescribed Tab metoclopramide 10 mg TDS and Tab ranitidine 150 mg BD for five days. About 30 min after oral administration of both medicines, her eyes rolled involuntary upward, leading to lateral deviation of the eyes, and mouth jaws clenched as if “dislocated jaws.” The patient was immediately brought into an emergency department (ED) of a public tertiary care hospital. A drug challenge test was done which resulted in the withdrawal of metoclopramide. The accompanied sister later disclosed that the patient had taken metoclopramide and ranitidine from a private clinic earlier in the day. The patient self-assumed to have a sudden seizure, due to excessive hot weather and dehydration. A slow intravenous infusion of 50 mg/mL diphenhydramine hydrochloride in 0.9% w/v NaCl 100 mL was administered stat. Consequently, the symptoms vanished after approximately 30 min of the therapy, devoid of relapse. The patient was discharged from ED post 8 hours of monitoring with complete recovery. Physicians frequently prescribe metoclopramide to treat nausea and vomiting, which may cause adverse drug reaction of acute dystonic oculogyric crisis (OGC). Due to its unwanted and unpredictable extrapyramidal symptoms, metoclopramide should be prescribed and dispensed with caution. Thorough history taking at ED is imperative for correct early diagnosis and treatment, as metoclopramide-induced dystonic OGC has a high probability of confusion with other causes of dystonia such as conversion and seizures, encephalitis, tetanus, and hypercalcemic tetany.

Resistance patterns, prevalence, and predictors of fluoroquinolones resistance in multidrug resistant tuberculosis patients

Abstract Background Fluoroquinolones are the backbone of multidrug resistant tuberculosis treatment regimens. Despite the high burden of multidrug resistant tuberculosis in the country, little is known about drug resistance patterns, prevalence, and predictors of fluoroquinolones resistance among multidrug resistant tuberculosis patients from Pakistan. Objective To evaluate drug resistance patterns, prevalence, and predictors of fluoroquinolones resistance in multidrug resistant tuberculosis patients. Methods This was a cross-sectional study conducted at a programmatic management unit of drug resistant tuberculosis, Lady Reading Hospital Peshawar, Pakistan. Two hundred and forty-three newly diagnosed multidrug resistant tuberculosis patients consecutively enrolled for treatment at study site from January 1, 2012 to July 28, 2013 were included in the study. A standardized data collection form was used to collect patients’ socio-demographic, microbiological, and clinical data. SPSS 16 was used for data analysis. Results High degree of drug resistance (median 5 drugs, range 2–8) was observed. High proportion of patients was resistant to all five first-line anti-tuberculosis drugs (62.6%), and more than half were resistant to second line drugs (55.1%). The majority of the patients were ofloxacin resistant (52.7%). Upon multivariate analysis previous tuberculosis treatment at private (OR = 1.953, p = 0.034) and public private mix (OR = 2.824, p = 0.046) sectors were predictors of ofloxacin resistance. Conclusion The high degree of drug resistance observed, particularly to fluoroquinolones, is alarming. We recommend the adoption of more restrictive policies to control non-prescription sale of fluoroquinolones, its rational use by physicians, and training doctors in both private and public–private mix sectors to prevent further increase in fluoroquinolones resistant Mycobacterium tuberculosis strains.

Evaluation of the Pharmaceutical Quality of Different Brands of Ranitidine Tablets Manufactured in Bangladesh: A Pharmaceutical and Public Health Prospective.

Drug counterfeiting and production of substandard drug is a global problem. Substandard or counterfeit drugs are threat for the effective treatment of diseases and highly worsen the quality of life of patients. This study was aimed to assess the pharmaceutical quality of ranitidine hydrochloride tablets manufactured in Bangladesh. Tablets were collected from different parts of Bangladesh and quality parameters were evaluated according to the United States Pharmacopoeia and the British Pharmacopoeial methods. The potency of tablets was measured spectrophotometrically. Weight variation and disintegration time were performed according to pharmaceutical monographs. Among 43 brands tested, 8 failed to comply with the USP specification (active ingredient: 90±10%) due to containing of less amount of ranitidine of which 6 brands were spurious and 2 were substandard in nature. Two brands did not comply with the specification for weight variation of tablets whereas all brands passed disintegration time test. The findings clearly demonstrate the production of substandard ranitidine tablets in Bangladesh. The drug control authority of Bangladesh should take effective steps to prevent the production of substandard drugs to secure public health.
