Натрия аминосалицилата дигидрат
Натрия аминосалицилата дигидрат Uses, Dosage, Side Effects, Food Interaction and all others data.
An antitubercular agent often administered in association with isoniazid. The sodium salt of the drug is better tolerated than the free acid.
Натрия аминосалицилата дигидрат is an anti-mycobacterial agent used with other anti-tuberculosis drugs (most often isoniazid) for the treatment of all forms of active tuberculosis due to susceptible strains of tubercle bacilli. The two major considerations in the clinical pharmacology of aminosalicylic acid are the prompt production of a toxic inactive metabolite under acid conditions and the short serum half life of one hour for the free drug. Натрия аминосалицилата дигидрат is bacteriostatic against Mycobacterium tuberculosis (prevents the multiplying of bacteria without destroying them). It also inhibits the onset of bacterial resistance to streptomycin and isoniazid.

For the treatment of tuberculosis
Натрия аминосалицилата дигидрат is also used to associated treatment for these conditions: Tuberculosis (TB)
How Натрия аминосалицилата дигидрат works
There are two mechanisms responsible for aminosalicylic acid's bacteriostatic action against Mycobacterium tuberculosis. Firstly, aminosalicylic acid inhibits folic acid synthesis (without potentiation with antifolic compounds). The binding of para-aminobenzoic acid to pteridine synthetase acts as the first step in folic acid synthesis. Натрия аминосалицилата дигидрат binds pteridine synthetase with greater affinity than para-aminobenzoic acid, effectively inhibiting the synthesis of folic acid. As bacteria are unable to use external sources of folic acid, cell growth and multiplication slows. Secondly, aminosalicylic acid may inhibit the synthesis of the cell wall component, mycobactin, thus reducing iron uptake by M. tuberculosis.
