Drug interactions occur when medications are taken together. some interactions are wanted; others are undesirable and even life-threatening. give two reasons for giving medications together, and cite two types of dangerous drug interactions.

Reason for giving medication together

1.)They reduce development of drug resistance since a pathogen or tumor is less likely to have resistance to multiple drugs simultaneously

2.) It has a lower treatment failure rate

Dangerous drug interactions include;

1.)Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are widely prescribed, and widely recognized to carry a high risk for drug/drug interactions

2.)Coadministration of clarithromycin with vasodilating calcium-channel blockers, such as amlodipine and felodipine, can cause hypotension and acute renal failure.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
