4.2 Therapeutic Uses

The US FDA announced on May 31, 1979, that their Anti-infective and Topical Drugs Advisory Committee and Fertility and Maternal Health Advisory Committee, as well as other studies, had concluded there was no adequate evidence that the then-available vaginal sulfonamides formulations were effective either for the treatment of vulvovaginitis caused by Candida albicans, Trichomonas vaginalis, or Gardnerella vaginalis (Hemophilus vaginalis) or for relief of the symptoms of these conditions. /Sulfonamides (vaginal)/

Sulfonamides are absorbed from the vaginal mucosa and are distributed into breast milk. Use is not recommended in nursing mothers since sulfonamides may cause hyperbilirubinemia in the infant. In addition, sulfonamides may cause hemolytic anemia in glucose-6-phosphate dehydrogenase-deficient neonates. /Sulfonamides (vaginal)/

5 Pharmacology and Biochemistry
5.1 Pharmacology

Sulfanilamide is a sulfonamide antibiotic. The sulfonamides are synthetic bacteriostatic antibiotics with a wide spectrum against most gram-positive and many gram-negative organisms. However, many strains of an individual species may be resistant. Sulfonamides inhibit multiplication of bacteria by acting as competitive inhibitors of p-aminobenzoic acid in the folic acid metabolism cycle. Bacterial sensitivity is the same for the various sulfonamides, and resistance to one sulfonamide indicates resistance to all. Most sulfonamides are readily absorbed orally. However, parenteral administration is difficult, since the soluble sulfonamide salts are highly alkaline and irritating to the tissues. The sulfonamides are widely distributed throughout all tissues. High levels are achieved in pleural, peritoneal, synovial, and ocular fluids. Although these drugs are no longer used to treat meningitis, CSF levels are high in meningeal infections. Their antibacterial action is inhibited by pus.

5.4 Absorption, Distribution and Excretion

Absorption

Sulfonamides are absorbed through the vaginal mucosa. There are no pharmacokinetic data available describing how much of an intravaginal dose reaches the systemic circulation.

ABSORPTION /OF SULFONAMIDES/ FROM SKIN & VAGINA IS ERRATIC. ONCE INTO BLOODSTREAM, SULFONAMIDES BIND TO SERUM ALBUMIN TO VARYING DEGREES... PROTEIN-BINDING LIMITS PENETRANCE INTO TISSUES & GLOMERULAR FILTRATION &...IS DETERMINANT OF DISTRIBUTION & RATE OF EXCRETION. /SULFONAMIDES/

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1105


Sulfonamides are eliminated from the body partly as the unchanged drug and partly as metabolic products. The largest fraction is excreted in the urine, and the half life of sulfonamides in the body is thus dependent on renal function. Small amounts are eliminated in the feces and in bile, milk, and other secretions. /Sulfonamides/

Gilman, A.G., T.W. Rall, A.S. Nies and P. Taylor (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 8th ed. New York, NY. Pergamon Press, 1990., p. 1049


Except for sulfonamides especially designed for their local effects in the bowel, this class of drugs is rapidly absorbed from the gastrointestinal tract. Approximately 70 to 100% of an oral dose is absorbed, and sulfonamide can be found in the urine within 30 minutes of ingestion. The small intestine is the major site of absorption, but some of the drug is absorbed from the stomach. Absorption from other sites, such as the vagina, respiratory tract, or abraded skin, is variable and unreliable, but a sufficient amount may enter the body to cause toxic reactions in susceptible persons or to produce sensitization. /Sulfonamides/

...DOGS...ACETYLATE SULFAMOYL GROUP & EXCRETE...N1-ACETYLSULFANILAMIDE...

The Chemical Society. Foreign Compound Metabolism in Mammals. Volume 1: A Review of the Literature Published Between 1960 and 1969. London: The Chemical Society, 1970., p. 424


When sulfanilamide, p-aminobenzoic acid, 4-aminobiphenyl, 2-aminofluorene or 1-aminopyrene was given orally to dogs, the corresponding N-acetyl and N-formyl derivatives were isolated from urine or feces. ... Dog intestinal flora and several bacterial strains exhibited both N-acetylating and N-formylating activities, in varying degrees, toward all of the arylamines tested. ... The results /show/ that the intestinal microflora plays an important role in the formation of N-acyl derivatives from arylamines in dogs.

5.6 Mechanism of Action

Sulfanilamide is a competitive inhibitor of bacterial enzyme dihydropteroate synthetase. This enzyme normally uses para-aminobenzoic acid (PABA) for synthesizing the necessary folic acid. The inhibited reaction is normally necessary in these organisms for the synthesis of folic acid. Without it, bacteria cannot replicate.


Sulfonamides are structural analogs and competitive antagonist of para-aminobenzoic acid ... and thus prevent normal bacterial utilization of para-aminobenzoic acid for the synthesis of folic acid (pteroylglutamic acid). ... More specifically, sulfonamides are competitive inhibitors of dihydropteroate synthase, the bacterial enzyme responsible for the incorporation of para-aminobenzoic acid into dihydropteroic acid, the immediate precursor of folic acid. /Sulfonamides/
