The minimal inhibitory concentration (MIC) values of sulfadiazine, penicillin, and rifampin for meningococcal strains isolated from civilians during 1970 were compared. The strains were isolated from various sources and geographical areas and represented several serogroups. The ranges of MIC values were as follows: 0.05 to 20 mg/100 ml for sulfadiazine, 0.01 to 0.4 mug/ml for penicillin, and 0....

The oral pharmacokinetics of three sulfonamides, sulfadimidine (pKa 7.5), sulfadiazine (pKa 6.5) and sulfanilamide (pKa 10.5), with different rates of unionization in rumen juice, were compared in Shiba goats to clarify the relationship between drug absorption profiles after their oral administration as well as their degree of unionization in the rumen. Sulfonamides were administered either int...

The efficacy of the combination of pyrimethamine and sulfadiazine for the treatment of congenital Toxoplasma gondii infection in rhesus monkeys was studied. The dosage regimen for pyrimethamine and sulfadiazine was established by pharmacokinetic studies in two monkeys. Those studies showed that the distributions of both drugs followed a one-compartment model. The serum elimination half-lives we...

The pharmacokinetics of 2,000 mg of sulfadiazine administered twice daily (BID) versus those of 1,000 mg administered four times a day were compared in eight human immunodeficiency virus-infected patients. No differences in pharmacokinetic parameters were detected between the regimens. These data provide a pharmacokinetic rationale for BID dosing of sulfadiazine for the treatment and suppressio...

Antibiotics, such as sulfadiazine, reach agricultural soils directly through manure of grazing livestock or indirectly through the spreading of manure or sewage sludge on the field. Knowledge about the fate of antibiotics in soils is crucial for assessing the environmental risk of these compounds, including possible transport to the groundwater. Transport of (14)C-labelled sulfadiazine was inve...

Sulphonamide motif is found extensively in numerous chemotherapeutic drug candidates, it acts by stopping the production of folate inside bacterial cell. Current research has established synthesis and characterization new bioprecursor prodrugs sulfadiazine. The first prodrug, 3, was synthesized via coupling diazonium salt sulfadiazine with ethyl acetoacetate AcONa at 0 °C. second sulfadiazine-p...

Silver sulfadiazine has been used as topical medication in the treatment of partial-thickness burns or secondary degree burns for many years. Pain during daily wound cleansing is the main problem. Urgotul SSD, a hydrocolloid dressing with silver sulfadiazine (SSD) has been reported to reduce infection and exhibit antimicrobial activity in burn wounds. The purpose of the present study was to com...

The title compound, [Mn(C(10)H(9)N(4)O(2)S)(2)(C(10)H(8)N(2))], contains a distorted octa-hedral [Mn(sdz)(2)(bpy)] (sdz is the sulfadiazine anion and bpy is 2,2'-bipyridine) complex mol-ecule. A three-dimensional network is generated by N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds from the sulfadiazine ligands.

A pharmacokinetic and bioavailability study of sulfadiazine combined with trimethoprim (sulfadiazine/trimethoprim) was carried out in fifteen healthy young ostriches after intravenous (i.v.), intramuscular (i.m.) and oral administration at a total dose of 30 mg/kg body weight (bw) (25 and 5 mg/kg bw of sulfadiazine and trimethoprim, respectively). The study followed a single dose, three periods...
