NSAIDs may be grouped according to their preference for COX-1 and COX-2 enzymes. Those that favor COX-1 are more likely to cause gastrointestinal side effects. Those that favor COX-2 have a higher risk of cardiovascular effects but less gastrointestinal effects. Higher dosages of NSAIDs tend to result in more COX-2 enzyme inhibition (and more cardiovascular side effects), even in those NSAIDs traditionally seen as low risk (such as ibuprofen). NSAIDs with higher activity against COX-2 enzymes should be used with caution in people with cardiovascular disease or at increased risk of cardiovascular disease.
Meloxicam use can result in gastrointestinal toxicity and bleeding, headaches, rash, and very dark or black stool (a sign of intestinal bleeding). Like other NSAIDs , its use is associated with an increased risk of cardiovascular events such as heart attack and stroke .  It has fewer gastrointestinal side effects than diclofenac ,  piroxicam ,  naproxen ,  and perhaps all other NSAIDs which are not COX-2 selective.  Although meloxicam inhibits formation of thromboxane A, it does not appear to do so at levels that would interfere with platelet function.
Sore throat usually is described as pain or discomfort in the throat area. A sore throat may be caused by bacterial infections, viral infections, toxins, irritants, trauma, or injury to the throat area. Common symptoms of a sore throat include a fever, cough, runny nose, hoarseness, earaches, sneezing, and body aches. Home remedies for a sore throat include warm soothing liquids and throat lozenges. OTC remedies for a sore throat include OTC pain relievers such as ibuprofen or acetaminophen. Antibiotics may be necessary for some cases of sore throat.
