Abstract

Giardia Lamblia is considered as the most important cause of parasitic diarrhoea in children and adults. The epidemiology of the infection is determined by environmental and regional factors. The sensitivity of man for this infection depends on factors related to man himself and his environment. Structural changes of the gut such as cellular infiltration and villous atrophy, and functional derangements like malabsorption can explain part of the symptoms. The application of different procedures for the parasitological diagnosis with a variable degree of sensitivity is the cause of difference in recorded prevalence data. This infectious disease can be treated with a number of drugs; single dose treatment is to be preferred especially in childhood. Results of treatment i.a. with a single dose ornidazole are reported.

Stability of fumagillin in an extemporaneously prepared ophthalmic solution.

The stability of fumagillin 70 microg/mL (as the bicyclohexylammonium crystal) in an extemporaneously prepared ophthalmic solution was studied. An ophthalmic solution of fumagillin 70 microg/mL was prepared by combining 120 mg of fumagillin bicyclohexylammonium crystals with 20 mL of 0.9% Sodium Chloride Injection, USP, and 20 mL of an ophthalmic irrigating solution. The solution was stored in 12 sterile semi-opaque dropper bottles; 4 bottles were stored at 25 degrees C exposed to light, 4 were stored at 25 degrees C in the dark, and 4 were stored at 4 degrees C in the dark. Samples were taken on days 0, 7, 14, 21, and 28 and analyzed by high-performance liquid chromatography. Sterility was tested as well. In the solutions stored at 25 degrees C, 17-30% of the initial drug concentration was lost during the first week. The solution protected from light and stored at 4 degrees C lost about 12% of active drug by week 4. There was no change in color or odor in any of the solutions and only a minor change in pH over the study period. There was no evidence of microbial growth in any of the solutions tested. Fumagillin 70 microg/mL (as the bicyclohexylammonium crystal) in 0.9% sodium chloride injection and an ophthalmic irrigating solution containing benzalkonium chloride was stable in the dark for 14 days at 4 degrees C.

Physico-chemical characterization of meglumine antimoniate.

The leishmanicidal drug, meglumine antimoniate (MA), has been synthesized by the reaction of antimony oxyhydrated and N-methyl glucamine. Infrared and solid state NMR 13C analysis of MA and the ligand strongly suggests that antimony binds to N-methyl glucamine through the oxygen of C-3 carbon. Potentiometric titration indicated that, between pH 4.5 and 7.5, MA exists in the zwitterionic form.
