Drug Name Diflucan

Compared with full antibodies, fragments have superior tissue penetrability, more rapid renal elimination, and lower antigenicity. The pharmacokinetics of cardiac glycosides (A) are dictated by their polarity, i.e., the number of hydroxyl groups. Membrane penetrability is virtually nil in ouabain, high in digoxin, and very high in digitoxin.
The ability to chelate Ca2+ accounts for the propensity of tetracyclines to accumulate in growing teeth and bones. As a result, there occurs an irreversible yellowbrown discoloration of teeth and a reversible inhibition of bone growth. Because of these adverse effects, tetracycline should not be given after the second month of pregnancy and not prescribed to children aged 8 y and under.

 

Rifampin inhibits the bacterial enzyme that catalyzes DNA template-directed RNA transcription, i. e. , DNA-dependent RNA polymerase. Rifampin acts bactericidally against mycobacteria (M. tuberculosis, M. leprae), as well as many gram-positive and gram-negative bacteria. It is well absorbed after oral ingestion.
5-HT2B receptors on vascular endothelium promote release of vasorelaxant mediators (NO, p.120; prostacyclin, p.196) 5-HT released from platelets plays a role in thrombogenesis, hemostasis, and the pathogenesis of preeclamptic hypertension. Ketanserin is an antagonist at 5- HT2A receptors and produces antihypertensive effects, as well as inhibition of thrombocyte aggregation.
