In this study Isoniazid (INH) as one of the first line drugs in treatment of Tuberculosis was investigated to be loaded in Solid Lipid Nanoparticles (SLNs) for reducing hepatotoxicity as well as prolonging drug release. High shear homogenization method was performed to prepare INH SLNs. To compare biodistribution of INH before and after loading in SLNs, INH was labeled by Technetium 99 (Tc99) a...

This work deals with the preparation of pyridine-3-carbohydrazide (isoniazid, inh) cocrystals two ?-hydroxycarboxylic acids. The interaction glycolic acid (H2ga) or d,l-mandelic (H2ma) resulted in formation salts composition (inh)·(H2ga) (1) and [Hinh]+[Hma]–·(H2ma) (2) when reacted isoniazid. An N?-(propan-2-ylidene)isonicotinic hydrazide hemihydrate, (pinh)·1/2(H2O) (3), was also prepared by ...

Isoniazid (INH) is highly effective for the management of tuberculosis. However, it can cause liver injury and even liver failure. INH metabolism has been thought to be associated with INH-induced liver injury. This review summarized the metabolic pathways of INH and discussed their associations with INH-induced liver injury.

in this work poly eriochrome black t (ebt) was electrochemically synthesized on the glassy carbon electrode as electrode modifier. on the modified electrode, voltammetric behavior of isoniazid (inh) was investigated. the poly (ebt)-modified glassy carbon electrode has excellent electrocatalytic ability for the electrooxidation of isoniazid. this fact was appeared as a reduced overpotential of i...

BACKGROUND Quantifying isoniazid resistant (INH-R) tuberculosis (TB) is important because isoniazid resistance reduces the probability of treatment success, may facilitate the spread of multidrug resistance, and may reduce the effectiveness of isoniazid preventive therapy (IPT). METHODOLOGY/PRINCIPAL FINDINGS We used data reported to the World Health Organization between 1994-2009 to estimate...

Background: Anti-tuberculosis drugs-induced hepatotoxicity is associated with oxidative stress. Curcumin a powerful antioxidant and has been found to protect the liver from damaging effects of The study aimed assess curative protective against induced by anti TB- drugs (Isoniazid-Rifampicin) using an experimental model Albino rabbits. Methods: rabbits(n=24) were divided into four groups. Group ...

in this study, twenty-five strains of mycobacterium tuberculosis resistant to isoniazid (inh) were isolated from patients with tuberculosis (tb). nine strains (36%) were found to be virulent in guinea-pigs [root index virulence (riv» 1 ]. the remaining sixteen strains (64%) were non-virulent (riv <1). of the nine strains resistant to inh as well as virulent to guinea-pigs, eight of them were fo...

Novel mutations in NADH dehydrogenase (ndh) were detected in 8 of 84 (9.5%) isoniazid (INH)-resistant isolates (T110A [n = 1], R268H [n = 7]), but not in 22 INH-susceptible isolates of Mycobacterium tuberculosis. Significantly, all eight isolates with mutations at ndh did not have mutations at katG, kasA, or the promoter regions of inhA or ahpC, except for one isolate. Mutations in ndh appear t...

Pyridine-4-carboxylic acid hydrazide, commercially known as isoniazid (INH), is an antitubercular drug and is now widely used together with rifampicin and streptomycin for the chemotherapy of tuberculosis. Ritodrine hydrochloride (RTH), chemically, 1-(4-hydroxyphenyl)-2-[2-(4-hydroxyphenyl)ethylamino]propanol is a potent tocolytic drug and is a selective β2-adrenoceptor agonist and is used to c...
