Clofazimine also showed a dosage-dependent inhibition of neutrophil motility, lymphocyte transformation, [19] mitogen-induced PBMC proliferation [20] and complement-mediated solubilization of pre-formed immune complexes in vitro. [21] A mechanistic studying of clofazimine in human T cells revealed that this drug is a Kv1.3 channel blocker. [22]
Its precise mechanism of action is unknown but may involve mycobacterial DNA binding. Its oral absorption is quite variable, with 9 to 70% of the drug eliminated in the feces. Clofazimine achieves significant concentrations in tissues, including the phagocytic cells; it has a plasma half-life of 70 days. It is primarily excreted in bile, with ...
This mechanism involves the direct effects of antipsychotic drugs on glutamate receptors. By using the technique of functional neurochemical assay chlorpromazine and phenothiazine derivatives have been shown to have inhibitory effects on NMDA receptors that appeared to be mediated by action at the Zn site. It was found that there is an increase ...
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.
The mechanism of action is thought to be through disruption of mycolic acid. [5] [18] Expression of the ethA gene is controlled by ethR, a transcriptional repressor. It is thought that improving ethA expression will increase the efficacy of ethionamide and prompting interest by drug developers in EthR inhibitors as a co-drug. [4]
Xanomeline is an agonist that primarily targets the muscarinic acetylcholine receptor family of five muscarinic receptor subtypes, which are designated M 1-M 5. [2] While it binds with near identical affinity to all five of the muscarinic receptor subtypes as measured by displacement of a muscarinic radioligand, the preponderance of evidence suggests that xanomeline acts preferentially in the ...
[medical citation needed] Elucidation of the exact mechanism of action is ongoing but there is limited study due to the existence of more effective, safe muscle relaxants (e.g., diazepam, cyclobenzaprine, tizanidine), greatly limiting the potential benefit of identifying novel compounds which share chlorzoxazone's mechanism of action.
The exact mechanism of action in parkinsonian syndromes is not precisely understood, but it is known that trihexyphenidyl blocks efferent impulses in parasympathetically innervated structures like smooth muscles (spasmolytic activity), salivary glands, and eyes . In higher doses direct central inhibition of cerebral motor centers may contribute.
