The guanine derivative antiviral drug acyclovir (ACV) is one of the oldest molecules put downing triumphant market until date, being commercially accessible in a variety dosage forms for oral, topical and parenteral administrations. Clinical purpose this better to new agents due its potential values such as suppression recurrence, security profile, negligible interactions inexpensive. ACV sligh...

      The objective of the present study was to develop floating microspheres of cefpodoxime proxetil in order to achieve an extended retention in the upper GIT, which may result in enhanced absorption and thereby improved bioavailability. The microspheres were prepared by non-aqueous solvent evaporation method using polymers such as hydroxyl propyl methyl cellulose (HPMC K 15 M), ethyl cellulo...

We have shown that stool samples from different patients can be pooled at a 1:2 dilution and reliably assayed for Giardia lamblia antigen by a commercial microtiter enzyme-linked immunosorbent assay (ELISA) system (LMD Laboratories, Inc., Carlsbad, Calif.). Laboratories can reduce reagent costs by pooling specimens submitted for the detection of Giardia antigen by ELISA.
