New crystal forms of the antibiotic 4-aminosalicylic acid

Toleration and absorption of sodium para-aminosalicylate and para-aminosalicylic acid (neopasalate). Comparison with other forms of para-aminosalicylic acid.

Synthesis of a novel PEGylated colon-specific azo-based 4- aminosalicylic acid prodrug

Objective(s): 4-aminosalicylic acid (4-ASA) is an isomer of mesalazine that has recently been shown to be effective against inflammatory bowel disease (IBD), and more specifically, ulcerative colitis. However, the majority of orally administered 4-ASA is readily and extensively absorbed from the stomach and small intestine, so only a small amount is transported to the ...

Para-Aminosalicylic Acid: Pas

new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

Serum concentrations of para-aminosalicylic acid (PAS) produced by various forms of PAS.

Para-aminosalicylic acid (PAS) is now generally accepted as an effective antibacterial agent in the treatment of certain forms of tuberculosis when administered alone or in combination with one of the streptomycins. However, there remains a great deal of uncertainty as to the best method of administering the drug. Both the free acid and the sodium salt of PAS have been given in various dosage f...
