The US FDA announced on May 31, 1979, that its 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/

In the opinion of USP medical experts, triple sulfa vaginal preparations are not effective for any indication, including vulvovaginitis caused by Gardnerella vaginalis and use as a deodorant in saprophytic infections following radiation therapy. Also, USP medical experts do not recommend the use of vaginal sulfonamides, including the reformulated single-entry preparations, for the treatment of fungal infections of the vagina. /Sulfonamides/

The number of conditions for which the sulfonamides are therapeutically useful and constitute drugs of first choice has been reduced sharply by the development of more effective antimicrobial agents and by the gradual increase in the resistance of a number of bacterial species to this class of drugs. /Sulfonamides/

Many of the adverse effects that have been attributed to the sulfonamides appear to be hypersensitivity reactions. The incidence of hypersensitivity reactions appears to increase with increased sulfonamide dosage. Although cross-sensitization has been reported to occur between the various anti-infective sulfonamides, some diuretics such as acetazolamide and the thiazides, some goitrogens, and sulfonylurea antidiabetic agents, the association between hypersensitivity to sulfonamide anti-infectives and subsequent sensitivity reactions to non-anti-infective sulfonamides (e.g., thiazides, sulfonylurea antidiabetic agents, furosemide, dapsone, probenecid) appears to result from a predisposition to allergic reactions in general rather than to cross-sensitivity to the sulfa moiety per se. /Sulfonamides/
American Society of Health System Pharmacists. AHFS Drug Information 2008. Bethesda, Maryland 2008, p. 423
Various dermatologic reactions, including rash, pruritus, urticaria, erythema nodosum, erythema multiforme (Stevens-Johnson syndrome), Lyell's syndrome (may be associated with corneal damage), Behcet's syndrome, toxic epidermal necrolysis, and exfoliative dermatitis, have been reported in patients receiving sulfonamides. Because photosensitivity may also occur, patients should be cautioned against exposure to UV light or prolonged exposure to sunlight. A relatively high proportion of fatalities has occurred as a result of the Stevens-Johnson syndrome, especially in children. Although long-acting sulfonamides (which are no longer commercially available) have been associated most often with the Stevens-Johnson syndrome, other sulfonamides also have been reported to cause this reaction. The physician should be alert to the signs, including high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis, which may precede the onset of the cutaneous lesions of the Stevens-Johnson syndrome. If a rash develops during therapy, the sulfonamide should be discontinued at once. In rare instances, a skin rash may precede a more serious reaction such as Stevens-Johnson syndrome, toxic epidermal necrolysis, hepatic necrosis, and/or serious blood disorders. /Sulfonamides/
American Society of Health System Pharmacists. AHFS Drug Information 2008. Bethesda, Maryland 2008, p. 423
Fever, which may develop 7-10 days after the initial sulfonamide dose, is a common adverse effect of sulfonamide therapy. Serum sickness syndrome or serum sickness-like reactions (e.g., fever, chills, rigors, flushing, joint pain, urticarial eruptions, conjunctivitis, bronchospasm, leukopenia), have been reported; rarely, anaphylactoid reactions and anaphylaxis may occur. Lupus erythematosus-like syndrome, disseminated lupus erythematosus, angioedema, vasculitis, vascular lesions including periarteritis nodosa and arteritis, cough, shortness of breath, chills, pulmonary infiltrates, pneumonitis (which may be associated with eosinophilia), fibrosing alveolitis, pleuritis, pericarditis with or without tamponade, allergic myocarditis, hepatitis, hepatic necrosis with or without immune complexes, parapsoriasis varioliformis acuta, alopecia, conjunctival and scleral injection, periorbital edema, and arthralgia have also been reported. /Sulfonamides/

Individual sulfonamides differ markedly in their absorption, distribution, and elimination. With the exception of sulfapyrimidine and sulfasalazine, which are only slightly absorbed, sulfonamides are generally well absorbed from the GI tract. Approximately 70-90% of an oral dose of the absorbable sulfonamides is reportedly absorbed from the small intestine; small amounts may also be absorbed from the stomach. Sulfamethizole and sulfisoxazole (no longer commercially available in the US) are absorbed rapidly; peak blood concentrations are usually obtained within 2-4 hours. Sulfadiazine and sulfapyridine are absorbed at a slower rate with peak blood concentrations occurring within 3-7 hours. Administration of oral sulfonamides with food appears to delay, but not reduce, absorption of the drugs. /Sulfonamides/
American Society of Health System Pharmacists. AHFS Drug Information 2008. Bethesda, Maryland 2008, p. 425
Absorption of sulfonamides from the vagina, respiratory tract, or abraded skin is variable and unreliable; however, enough drug may be absorbed to induce sensitization or toxicity. /Sulfonamides/
American Society of Health System Pharmacists. AHFS Drug Information 2008. Bethesda, Maryland 2008, p. 425
Although only free (unmetabolized and unbound) sulfonamides are microbiologically active, blood concentrations are often determined on the basis of total sulfonamide concentration. Generally, sulfonamide plasma concentrations are approximately twice the blood concentrations. Wide variations in blood concentrations have been reported in different individuals receiving identical doses of the same sulfonamide. Blood total sulfonamide concentrations of 12-15 mg/dL have been reported to be optimal; blood concentrations greater than 20 mg/dL have been associated with an increased incidence of adverse reactions. /Sulfonamides/
American Society of Health System Pharmacists. AHFS Drug Information 2008. Bethesda, Maryland 2008, p. 425
Absorbable sulfonamides are widely distributed in the body. Although most sulfonamides appear to cross cell membranes, sulfisoxazole appears to be distributed only in extracellular fluid. Sulfonamides may appear in pleural, peritoneal, synovial, amniotic, prostatic, and seminal vesicular fluid, and aqueous humor. Concentrations of some sulfonamides in the CSF may reach 35-80% of blood concentrations. Small amounts of sulfonamides are also distributed into sweat, tears, saliva, and bile. /Sulfonamides/

Metabolism of sulfonamide drugs in animals includes conjugation at the N4-position (acetyl, sulfate, glucuronic acid, and glucose), conjugation at the N1-position (sulfate and glucuronic acid), removal of the p-amino group (formation of the desamino metabolite), ring hydroxylation, and conjugation of the ring hydroxylation products. Dietary nitrite enhances the production of the desamino metabolite of sulfathiazole. The intermediate leading to the desamino metabolite of sulfamethazine is weakly mutagenic in the Ames test (Nelson et al., 1987; Paulson et al., 1987).
Although the liver is the major site of metabolism, sulfonamides may also be metabolized in other body tissues. Most sulfonamides are metabolized mainly by N4-acetylation. The degree of acetylation, which is a function of time, varies from less than 5% for sulfamethizole to up to 40% for sulfadiazine. The N4-acetyl metabolites, which do not possess antibacterial activity, have greater affinity for plasma albumin than does the nonacetylated drug and are usually less soluble than the parent sulfonamide, particularly in acidic urine. Like acetyl derivatives, glucuronide derivatives do not possess antibacterial activity; however, glucuronide derivatives are water soluble, appear to resemble the nonacetylated sulfonamide in plasma binding capacity, and have not been associated with adverse effects. /Sulfonamides/

Sulfathiazole...is one of the short-acting sulfonamides & in man is excreted in urine as unchanged sulfathiazole (63% of dose), N4-acetylsulfathiazole (29%), sulfathiazole-N4-glucuronide (0.8%), sulfathiazole-N4-sulfate (0.5%) & sulfathiazole-N1-glucuronide (3.8%).

Deposition kinetics, metabolism and urinary excretion of sulfathiazole were investigated in German black head sheep following single oral administration (100 mg/kg). Kinetic evaluation of plasma levels was performed using a two-compartment best fit model. Sulfathiazole is significantly metabolized to N4-acetyl metabolite in the rumen fluid. The drug is very poorly absorbed since the minimum effective concentration in plasma was not attained at any time following oral administration. The prolonged elimination half-life in sheep may be due to a low rate of drug absorption from the rumen and gastro-intestinal tract. Sulfathiazole was mainly excreted in the urine as free drug and N4-acetyl metabolite.

Sulfonamides are generally classified as short-acting, intermediate-acting, or long-acting depending on the rate at which they are absorbed and eliminated. Sulfamethizole, sulfasalazine, and sulfisoxazole are generally considered to be short-acting sulfonamides and reportedly have plasma half-lives of about 4-8 hours. Sulfadiazine and sulfapyridine are generally considered to be intermediate-acting sulfonamides and reportedly have plasma half-lives of about 7-17 hours. /Sulfonamides/

Sulfonamides are usually bacteriostatic in action. Sulfonamides interfere with the utilization of p-aminobenzoic acid (PABA) in the biosynthesis of tetrahydrofolic acid (the reduced form of folic acid) cofactors in susceptible bacteria. Sulfonamides are structural analogs of PABA and appear to interfere with PABA utilization by competitively inhibiting the enzyme dihydropteroate synthase, which catalyzes the formation of dihydropteroic acid (a precursor of tetrahydrofolic acid) from PABA and pteridine; however, other mechanism(s) affecting the biosynthetic pathway also may be involved. Compounds such as pyrimethamine and trimethoprim, which block later stages in the synthesis of folic acid, act synergistically with sulfonamides. Only microorganisms that synthesize their own folic acid are inhibited by sulfonamides; animal cells and bacteria which are capable of utilizing folic acid precursors or preformed folic acid are not affected by these drugs. The antibacterial activity of the sulfonamides is reportedly decreased in the presence of blood or purulent body exudates. /Sulfonamides/
American Society of Health System Pharmacists. AHFS Drug Information 2008. Bethesda, Maryland 2008, p. 424
The sulfonamides are structural analogs of para-aminobenzoic acid (PABA) and competitively inhibit an enzymatic step (dihydropterate synthetase) during which PABA is incorporated into the synthesis of dihydrofolic acid (folic acid). Because dihydrofolate synthesis is reduced, the levels of tetrahydrofolate (folinic acid) formed from dihydrofolate diminish. Tetrahydrofolate is an essential component of the coenzymes responsible for single carbon metabolism in cells. Acting as antimetabolites to PABA, sulfonamides eventually block, in a complex fashion, several enzymes. These enzymes include those needed for the biogenesis of purine bases; for the transfer of desoxyuridine to thymidine; and for the biosynthesis of methionine, glycine, and formylmethionyl-transfer-RNA. This results in suppression of protein synthesis, impairment of metabolic processes, and inhibition of growth and multiplication of those organisms that cannot use preformed folate. The effect is bacteriostatic, although a bactericidal action is evident at the high concentrations that may be found in urine.
