d) Quinolones
Answer:
Quinolones
NSAIDs Interaction with Quinolones
The NSAIDs are a group of drugs that are used to
treat pain and inflammation. There is a large class of NSAIDs called COX-2
inhibitors, but there are also other kinds of NSAIDs.
The COX-2 inhibitors work by blocking the enzyme
cyclooxygenase 2 (COX-2). They do this by inhibiting the production of
prostaglandins, which cause inflammation.
NSAIDs interact with quinolones in two
different ways:
1)
Quinolones can increase the risk
of bleeding when taken with an NSAID. This is because quinolone antibiotics can
produce enzymes in your body that break down the blood anticoagulant warfarin
(Coumadin®) into its active form, which increases its anticoagulant effect.
2)
Quinolones also have a similar
effect to some NSAIDs on platelet aggregation or blood clotting.
Quinolones
are a group of broad-spectrum antibiotics that are commonly used to treat a
variety of bacterial infections. In this article, we will discuss the history,
mechanism of action, indications, side effects, and other important information

directions for research and development
In
summary, quinolones are a class of antibiotics that have a broad spectrum of
activity against bacterial infections. They work by inhibiting DNA synthesis
and targeting bacterial enzymes. Quinolones have a wide range of indications,
including respiratory, urinary tract, skin and soft tissue, gastrointestinal,
bone and joint, and sexually transmitted infections. However, they also have
potential side effects and drug interactions that must be considered before
use. As with all antibiotics, proper dosing and monitoring are critical to
ensure optimal clinical outcomes.
