THIN LAYER CHROMATOGRAPHY OF ANALGESICS Introduction: Analgesics are compounds that relieve pain. They range from over the counter drugs such as aspirin, which is consumed at a rate of 40 million pounds per year, to prescription drugs like morphine and other related narcotics. In addition to aspirin, several other chemically similar compounds are widely used in nonprescription analgesic tablets. The most common non-aspirin pain relievers are acetaminophen and ibuprofen. Caffeine, a stimulant, is sometimes added to analgesic formulation to overcome...
