Sulfonamides are among one of the oldest drugs to be used as antibiotics. They were invented in 1930's. Nowadays doctors prefer to prescribe them as the traditional drug of choice for urinary tract infections and sexually transmitted diseases. Currently, the new development of antibiotics to combat illnesses caused by bacterial resistant strains and have limited the usefulness of Sulfa medications.

Upon successful completion of this presentation you should be able to:
• Understand and communicate your knowledge of Sulfonamides mode of action and bacterial resistance
• Identify and understand the contra indications, common signs and symptoms of allergic reactions to Sulfonamides.
• Identify 3 common trade names for sulfonamides and select indication for use between different patient population.

Type and class of Pathogen
Sulfonamides have been in use since the 1930's , these drugs are effective against both gram- negative and gram - positive bacteria. Sulfonamides are know as broad spectrum antimicrobial drugs; they are effective against a wide variety of microorganisms most Enterobacteriaceae, Chlamydia trachomatis, Nisseria, Haemophilus influenzae,, Norcardia, E.Coli , P. mirabilis some staphylococci, and many streptococci (with exception of Enterococcus faecalis). They are used for treatment of Protozoan such as Toxoplasma gondii, and mycobacterial. Sulfonamides are use for treatment and prophylaxis of Pneumocytis carinii and Shigella small bowel infections.

Mode of Action Sulfonamides are bacteriostatic anti-invectives that "inhibit bacteria" growth but do not destroy it (Lilley, Collins, Harrington & Snyder, 2011). By preventing the bacterial synthesis of a…...

...absolute ethanol catalyzed by concentrated sulfuric acid and later neutralized with a 10% sodium carbonate solution. Neutralization raised the pH of the overall reaction system to about 8 creating a precipitate of Benzocaine. Recrystallization of the crude product was performed to increase purity. Our experiment produced a 0.0705g crude sample of Benzocaine with a melting point of 86.55 – 88oC. Recrystallization produced a 0.0411g pure sample with a melting point of 89.5 – 90.9oC. Pure Benzocaine melts at 90oC. Benzocaine is an odorless, white, rhombohedric crystal with low water solubility. It is sensitive to light exposure and to temperatures above 30° C. As a drug, it has a low potency and low systemic toxicity. It is also a possible sulfonamide antagonist. Reaction: H+ + CH3CH2OH p-Aminobenzoic acid ethanol Benzocaine Since the reaction is in equilibrium, excess water would cause the reaction to favor the reactants and thus not produce the desired product. Our intent is to create the ethyl esther functional group. Results: Benzocaine Product Crude Purified Mass .0705g .0411g M.P. 86.55-88oC 89.5-90.9oC Melting Point % error Crude = 90o-88o/90 x 100 = 2.2% error Purified = 90.9o-90o/90 x 100 = 1.0% error Theoretical yield 0.131g p-aminobenzoic acid x 1mol/137.14g = 9.55x10-4 mol p-aminobenzoic acid * 1.20 mL ethanol x .789g/mL x 1mol/46.07g = 2.055x10-2 mol ethanol ......

...needles and personal items. Skin assessment includes assessing for ascites and measuring abdominal girth, observing for signs of bleeding (hematuria, melena, ecchymosis), excoriation, pruritus and skin breakdown as there is an increase chance for bleeding. Advising the individual to apply calamine lotion may prevent dryness and scratching. Prothrombin time may be prolonged due to liver dysfunction, which causes individuals to bleed easily. The importance of reducing the demand on the liver must be stressed, these restrictions include avoidance of alcohol, no heavy lifting or strenuous activity until the liver returns to normal size, side effects and dangers of taking over the counter or prescribed medications (Acetaminophen, Aspirin, Sulfonamides, Ibuprofen) that are toxic to the liver or metabolized by the liver should be avoided as they cause cumulative toxic effects. Emphasizing the importance of physical examination, laboratory tests, which include liver function panel, Prothrombin levels and albumin, are critical to monitor disease progression. In addition to these nursing priorities, the health professional must also assess effect of illness on economic factor of the individual because of their loss of role function in the family. Utilizing community resources to assist the individual with activities of daily living include Meal on Wheels and housekeeping services.

Antibiotic Resistant Bacteria problem primarily is that it causes some patients to be incurable to previously cured infections is because the emergence of antibiotic resistance is primarily due to excessive and often unnecessary use of antibiotics in humans and animals. According to G. Gopal Rio “Risk factors for the spread of resistant bacteria in hospitals and the community can be summarized as overcrowding, lapses in hygiene or poor infection control practices. In the 1930s, the first class of antibiotics that was developed was called sulfonamides. This antibiotic is crucial in the treatment of bronchitis, meningitis and urinary tract infections, travelers’ diarrhea,” (Cummings, n.d.) and a host of other infections. Therefore, it is vital that the “Development of new classes of antibiotics is important because of the prevalence of antibiotic-resistant bacteria” (Cummings, n.d.). For example, a patient were infected with bronchitis and has a strain of bacteria resistance to sulfonamides then their doctors would, essentially; prescribe another type of antibiotic. In conclusion, although the indiscriminate use of antibiotics is enhanced by their free and uncontrolled availability ‘across the counter’, particularly in developing and Third World countries where regulatory mechanisms leave much to be desired. Likewise, in developed countries, there is also a clear connection between the overall antibiotic intake and the rate of the recurrence of the discovery of antibiotic-resistant bacteria. ......

...N'-diphenylcarbamide). Some structural amides are; * Acetamides * Acrylamides * Anilides * Benzamides * Naphthylamides * Formamides * Lactams * Salicylamides * Sulfonamides * Thioamides * Fatty amidesAn amide is hydrolyzed to yield an amine and a carboxylic acid under strong acidic conditions. The reverse of this process resulting in the loss of water to link amino acids is wide in nature to form proteins, the principal constituents of the protoplasm of all cells. Acyl halides are the most reactive but amides the least reactive among carboxylic acid derivatives, as in order of "acyl halides > anhydrides > esters ¡Ã acids > amides". In homogeneous solvent systems, amides react with water only in the presence of strong acid or base catalysts under heating. Because of the nitrogen non-bonded electron pair with the carbonyl group, amides are very polar and the basicity is weaker than amines. Electrophiles bond to oxygen atom in preference to the nitrogen in an amide. One example of this reaction is the production of nitriles by dehydration of primary amides when treated with thionyl chloride. The addition of water to nitriles (carbon-nitrogen triple bond) gives an amide.Sulfonamides are analogs of amides in which the atom attached to oxygen in solid bond is sulfur rather than carbon. Sulfonamides react with alkyl halides, acid halides, sulfonyl halides, epihalohydrins, ketones and aldehydes under basic conditions. Benzamide, the simplest aromatic......

...point was 181 ͦC and the refractive index was 1.586 indicating the unknown amine was aniline. Most amines are soluble in water usually and dissolve in aqueous acid due to their ability to hydrogen bond. As the carbon chains get longer, solubility decreases as the hydrocarbon chains have to force their way between water molecules, breaking hydrogen bonds between water molecules. In the experiment the unknown was not soluble in water. Secondly the Hinsberg test can distinguish primary, secondary, and tertiary amines and is based on sulfonamide formation. In the Hinsberg test, an amine is reacted with benzene sulfonyl chloride. If a product forms, the amine is either a primary or secondary amine, because tertiary amines do not form stable sulfonamides. If the sulfonamide that forms dissolves in aqueous sodium hydroxide solution, it is a primary amine. If the sulfonamide is insoluble in aqueous sodium hydroxide, it is a secondary amine. The sulfonamide of a primary amine is soluble in an aqueous base because it still possesses an acidic hydrogen on the nitrogen, which can be lost to form a sodium salt. The unknown did not react indicating it was a tertiary amine. These results do not correspond with the compound aniline therefore there is some error in the experiment. Problems: 1. Would you expect the reaction product from benzenesulfonyl chloride and ammonia to be soluble or insoluble in a basic solution? Explain. The benzoyl chloride will react with the ammonia via......
