Tablet formulations are designed and tested using a laboratory machine called a Tablet Compaction Simulator or Powder Compaction Simulator. This is a computer controlled device that can measure the punch positions, punch pressures, friction forces, die wall pressures, and sometimes the tablet internal temperature during the compaction event.
Aspirin/paracetamol/caffeine is a combination drug for the treatment of pain, especially tension headache and migraine. [1] It contains aspirin , a non-steroidal anti-inflammatory drug ; paracetamol (acetaminophen), an analgesic ; and caffeine , a stimulant .
