List of Sulfonamides + Uses, Types & Side Effects - Drugs

  1. Sulfonamides (sulphonamides) are a group of man-made (synthetic) medicines that contain the sulfonamide chemical group. They may also be called sulfa drugs. Many people use the term sulfonamide imprecisely to refer only to antibiotics that have a sulfonamide functional group in their chemical structure
  2. The indications for chemotherapy with the sulfonamides and penicillin may be divided into those which are well established through common and consistent experience and those concerning which there is uncertainty either because of conflicting results recorded in the literature or because experience is still too limited or uncontrolled to provide a definite conclusion

Sulfonamides are one of the oldest broad-spectrum antimicrobial agents that work by competitively inhibiting bacterial metabolic enzymes needed for bacterial function. Indications: Sulfonamides are used to treat urinary tract infections, otitis media, acute exacerbations of chronic bronchitis, and travelers' diarrhea Sulfonamides (sulfa drugs) are drugs that are derived from sulfanilamide, a sulfur-containing chemical. Most sulfonamides are antibiotics, but some are prescribed for treating ulcerative colitis Sulfonamides are used to treat urinary tract infections, conjunctivitis, and toxoplasmosis. They also are used to prevent and treat burn-related infections and are used adjunctively with pyrimethamine for malaria. Indications for some sulfonamides are listed in Box 4-8. Individual sulfonamides have unique actions

For many indications, sulfonamides have been replaced by safer, and in some cases, more efficacious alternatives. Despite the relatively high incidence of adverse effects, sulfonamides maintain their place as treatment of choice for certain infectious diseases including Pneumocystis jirovecii pneumonia (PCP), uncomplicated cystitis, and. In bacteria, antibacterial sulfonamides act as competitive inhibitors of the enzyme dihydropteroate synthase (DHPS), an enzyme involved in folate synthesis. Sulfonamides are therefore bacteriostatic and inhibit growth and multiplication of bacteria, but do not kill them Example Indications: Sulfonamides can be used for burns, eye infections, and urinary tract infections (UTIs) among others Deaths associated with the administration of sulfonamides have been reported from hypersensitivity reactions, agranulocytosis, aplastic anemia and other blood dyscrasias. The presence of such clinical signs as sore throat, fever, pallor, purpura or jaundice may be early indications of serious blood disorders

Aminoglycosides are a group of antibiotics indicated for infections caused by gram-negative aerobic bacilli. They were replaced by newer, less-toxic drugs in treating less serious infections because these drugs have potentially serious adverse effects Therapeutic Indications and Dose Rates The sulfonamides are commonly used to treat or prevent acute systemic or local infections. Disease syndromes treated with sulfonamides include actinobacillosis, coccidiosis, mastitis, metritis, colibacillosis, pododermatitis, polyarthritis, respiratory infections, and toxoplasmosis

The sulfonamides are structural analogues of paraaminobenzoic acid (PABA) that have different solubility, absorption, and excretion characteristics. The combination of trimethoprim, a diaminopyrimidine antimicrobial, with a sulfonamide was shown to be synergistic in the late 1960s, and this combination is now used widely in clinical practice

Indications For Use Because of the emergence of resistant bacterial strains and the development of newer antibiotics, sulfa drugs are no longer used much (Karch, 2011, p.115) Kee, Hayes & McCuistion (2009) state Sulfonamides may be used as an alternative drug for clients allergic to penicillin Indications: CELEBREX is indicated for the management of the signs and symptoms of osteoarthritis, CELEBREX is a sulfonamide and both NSAIDs and sulfonamides may cause allergic type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people and/or sulfonamides (4) Indications and Usage (1) patient of the potential hazards to the fetus.

greatly increased or decreased frequency of urination or amount of urine. increased thirst. lower back pain. mood or mental changes. pain or burning while urinating. swelling of front part of neck. Check with your doctor as soon as possible if any of the following side effects occur 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 Sulfa drugs (also called sulphur drugs or sulfonamide-containing drugs) is an imprecise term that generally refers to drugs that contain a sulfonamide functional group in their chemical structure. These drugs have a variety of uses and can be classified into antibiotics and non-antibiotic drugs Trimethoprim-sulfamethoxazole (TMP-SMX), also known as co-trimoxazole, is a combination of two antimicrobial agents that act synergistically against a wide variety of bacteria. Although other combinations of sulfonamides are available with trimethoprim, TMP-SMX is by far the most widely used. This topic will review basic issues related to the. While sulfonamide drugs, including TMP/SMX, have a sulfonamide part in common (SO 2 NH 2), there are small — but crucial — differences between antibiotic and non-antibiotic sulfonamides. These differences mean that non-antibiotic sulfonamides don't cause your body to initiate an immune response, even if Bactrim does

Because sulfonamides are found to be excreted in breast milk it is advised to avoid giving trimethoprim / sulfa in the female rat that may be nursing young. Indications. Good choice for use in urinary tract infections or secondary infections. Drug Interactions or Contraindications Indications.

The evidence regarding an association between the nitrofuran and sulfonamide classes of antibiotics and birth defects is mixed. As with all patients, antibiotics should be prescribed for pregnant women only for appropriate indications and for the shortest effective duration. During the second and th Sulfonamides: The sulfa-related group of antibiotics, which are used to treat bacterial infection and some fungal infections. Examples of sulfonamides includes sulfadiazine, sulfamethizole (brand name: Thiosulfil Forte), sulfamethoxazole (), sulfasalazine (), sulfisoxazole (), and various high-strength combinations of three sulfonamides.. Sulfa drugs kill bacteria and fungi by interfering with.

the potentiated sulfonamides is lower than that to each individual agent;{R-20; 23} this is an important benefit because of the common resistance to sulfonamides and rapid development of resistance to diaminopyrimidines when used alone.{R-20} Cross-resistance between sulfonamides is considered complete and often occurs between pyrimidines, as well Sulfonamides competitively inhibit the incorporation of para-aminobenzoic acid (PABA) into dihydropteroic acid, a precursor of folic acid Trimethoprim is an inhibitor of dihydrofolate reductase and provides a sequential blockade of synthesis of tetrahydrofolat Sulfonamides Disclaimer - Please see package insert if applicable for additional information.

Folic Acid Synthesis Inhibitors

Sulfonamides, the first class of antimicrobial agents, were discovered in 1932 and put into clinical use in 1935 . Since then, they have been used extensively in many different clinical indications. The medium long-acting sulfonamides, sulfamethoxazole (SMZ) and sulfadiazine, remain the most useful members of this class of antimicrobial agents Safe and effective use of sulfonamides, such as sulfacetamide, in children has not been widely studied; some established indications in children exist (see Dosage). Sulfonamides should be avoided in infants and neonates less than 2 months of age because systemic sulfonamides may increase the risk of kernicterus in young infants by displacing. Sulfonamide antibiotics and other sulfonamide medications, defined by their inclusion of the sulfonamide structure (Fig. 1a), are commonly used medications. Sulfonamide antibiotics are a very common cause of drug-induced cutaneous reactions and are one of the two most common antibiotics (along with penicillins) to be listed as an allergy in the patient's medical record [1,2,3] Antimicrobial sulfonamides were the first antimicrobial agents used effectively to treat infectious diseases. However, because they may cause severe adverse drug reactions (ADRs) and because more effective agents have since been developed, sulfonamides now are used for only a few indications in specific groups, such as AIDS patients. Skin reactions, from benign rash to potentially lethal.

The volume of distribution is 1.5-2.71/kg for TMP and 0.3-0.7 1/kg for various sulfonamides. The plasma half-life of TMP is 1.9-4.3 h, whereas the plasma half-lives of the different sulfonamides vary between 2.7 and 14.0 h. About 50% of total TMP is bound to plasma proteins A similar formulation to the trimethoprim-sulfonamides for use in veterinary medicine is ormetoprim sulfadimethoxine, which has been used for the same indications as trimethoprim-sulfonamides. Doses for TMS combinations are listed in Table 8-10

Define sulfonamides. sulfonamides synonyms, sulfonamides pronunciation, sulfonamides translation, English dictionary definition of sulfonamides. Used to prevent the growth of bacteria, mainly in the treatment of urinary infections Sulfa Drugs. Sulfa drugs, also known as sulfonamides, are chemical compounds that contain a SO2NH2 moiety 2. Based on their chemical structure, these drugs are divided into three classes, however, they all have the same mechanism of action. These drugs inhibit bacterial growth by acting as a competitive inhibitor to the enzyme, p-aminobenzoic acid In addition, 1 of the metabolic products generated by hydrolysis is PABA, which inhibits the action of sulfonamides and is a known allergen. In patients with a known allergy to an ester anesthetic, the use of all other ester-type anesthetic agents should be avoided. Clinical indications of nerve laceration include paresthesias, shooting or. Potential for toxicity as for other sulfonamides if applied to extensive areas of the body surface. Interactions Drug: proteolytic enzymes are inactivated by silver in cream. Pharmacokinetics Absorption: Not absorbed through intact skin, however, approximately 10% could be absorbed when applied to second- or third-degree burns
