Biological Activity

Description	Sulfamethoxypyridazine (CL 13494) is a long-acting sulfonamide for treatment of Dermatitis herpetiformis.

In Vivo
In vivo	Sulfamethoxypyridazine is found to be highly effective in a preliminary study of P. carinii-infected rats. Sulfamethoxypyridazine is also found to be as effective as sulfamethoxazole in P. carinii-infected rats at 1 mg/kg of body weight/day. Sulfamethoxypyridazine is effective aganist a murine model of P. carinii with ED50s of 0.06 mg/kg/day and 0.08 mg/kg/day as determined by the Giemsa and silver stain scores, respectively. Sulfamethoxypyridazine at either 0.1 mg/kg/day or 0.3 mg/kg/day is found to be significantly more effective than sulfamethoxazole at 0.47 mg/kg/day) aganist a murine model of P. carinii. ^[1] Sulfamethoxypyridazine exhibits the biological half lives of 11.0 hours and 13.7 hours following im and sc administration, respectively, in goats. Sulfamethoxypyridazine exhibits the systemic availabilities of 68.6% and 58.7% following im and sc administration, respectively, in goats. ^[2] Sulfamethoxypyridazine exhibits the distribution and elimination half life of 0.1 hour and 6.28 hours, respectively, in goats. Sulfamethoxypyridazine exhibits the values of apparent volume of distribution at steady state and total body clearance of 0.39 mL/kg/min and 0.73 mL/kg/min, respectively, in goats. ^[3]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
