Eleven in-patients of the hospital for Tuberculosis and Chest Diseases, Hyderabad, who presented with psychiatric symptoms resulting in maladjustment were examined and placed in different diagnostic groups. There were five psychotics and six neurotics. Out of the five psychotics, three were manic and two were depressive. Among the six neutrotics, three were depressive and one each of anxiety, o...

A 24-year-old woman had recently started antitubercular therapy with isoniazid, ethambutol and rifampicin. This therapy was discontinued 2 weeks later due to an itchy, desquamative, erythematous, papular rash, with painful crusts and excoriations, spreading from the face and hands to the rest of the body. 5 days after withdrawal of all drugs, widespread desquamation and exfoliation with predile...

The importance of achieving concentrations of both streptomycin and isoniazid adequate to sterilize all parent drug-susceptible organisms was empasized by in vitro studies on the prevention of emergence of mutants resistant to these drugs (1). Many factors determine the concentrations of these agents to which multiplying tubercle bacilli are exposed in the human subject: dosage; absorption and ...

three antituberculosis medications are investigated in this work consist of rifampicin, isoniazid and pyrazinamide. the ultra violet (uv) spectra of these compounds are overlapped, thus use of suitable chemometric methods are helpful for simultaneous spectrophotometric determination of them. a generalized version of net analyte signal standard addition method (gnassam) was used for determinatio...

background and objectives: tuberculosis (tb) is the major public health problem in the world. each year there are 2-3 million deaths worldwide caused by tb. the increasing incidence of multi drug resistance tuberculosis (mdr-tb) worldwide highlights the urgent need to search for new anti-tuberculosis compounds. it has been reported that medicinal plant, dracocephalum kotschyi, possesses some an...

Limited data exist on the pharmacokinetic-pharmacodynamic (PK-PD) parameters of the bactericidal activities of the available antimycobacterial drugs. We report on the PK-PD relationships for isoniazid. Isoniazid exhibited concentration (C)-dependent killing of Mycobacterium tuberculosis H37Rv in vitro, with a maximum reduction of 4 log10 CFU/ml. In these studies, 50% of the maximum effect was a...

1. The reaction products of isoniazid with periodate-oxidized ribonucleosides and 5'-ribonucleotides have been characterized as the monohydrazones. 2. The stability, chromatographic and electrophoretic properties of the hydrazones are described. 3. (3)H-labelled isoniazid was shown to react with the 5'-linked terminal adenosine and cytidine groups of periodate-oxidized Escherichia coli transfer...

Pharmacokinetic characteristics of INH are presented. Adverse effects and toxicity caused by INH has been reviewed under the headings of neuropathy and seizures, hepatotoxicity, rhabdomyolysis, agranulocytosis, acidosis and other adverse drug reactions. Cases of poisoning by INH have been mentioned independently. Few case reports indicating symptoms of intoxication and the mechanism of toxicity...

Background: One third of the world’s population is infected with TB, and the disease is known as the second deadly global infection, even more severe than measles. The disease kills about 2 million people a year. Approximately 8 million people in the world are affected by advanced tuberculosis (TB). Objective: The current study aimed to determine the freq...
