Antimicrobial agents and chemotherapy, 40(4), 962-965 (1996-04-01)
A remarkably high rate of adverse events is associated with the use of trimethoprim-sulfamethoxazole in patients with human immunodeficiency virus type 1 infection. We examined the efficacies of sulfonamides alone in the prevention of Pneumocystis carinii pneumonitis, with the assumption
S K Garg et al.
Veterinary research, 28(1), 101-104 (1997-01-01)
The pharmacokinetics of sulfamethoxypyridazine (SMP) was investigated in goats after a single intramuscular (im) or subcutaneous (sc) administration (100 mg/kg body weight). The biological half lives of SMP following im and sc administration were found to be 11.0 and 13.7

The Journal of pharmacy and pharmacology, 47(7), 550-555 (1995-07-01)
The solubility of sulphamethoxypyridazine was measured at several temperatures in mixtures of water:ethanol and ethanol:ethyl acetate. Sulphamethoxypyridazine was chosen as a model drug to compare the solvation effects of proton donor-proton acceptor (water and ethanol) and proton acceptor (ethyl acetate)

Farmaco (Societa chimica italiana : 1989), 49(6), 381-386 (1994-06-01)
Derivative and difference spectrophotometric methods are described for the direct simultaneous analysis of combinations of Trimethoprim with sulfonamide drugs (sulfadiazine, sulfamethoxazole, sulfamethoxypyridazine) in commercial dosage forms. The more advantageous approach (derivative and difference mode) is suggested for each binary mixture.
M Thornhill et al.
The British journal of dermatology, 143(1), 117-126 (2000-07-25)
Twenty-five patients with mucous membrane pemphigoid (MMP), whose oral lesions were unresponsive to topical steroid treatment, were treated with 1 g daily of sulphamethoxypyridazine (SMXP), a long-acting sulphonamide antibiotic, in an open prospective clinical trial. Lesion severity was assessed objectively
