Pharmaceutical chemicals like APIs, Paracetamol, Ibuprofen, and Citric Acid are crucial in the healthcare industry. Active Pharmaceutical Ingredients (APIs) are the key components responsible for the therapeutic effects of medications. Paracetamol is a commonly used pain reliever and fever reducer in over-the-counter medications. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce inflammation, pain, and fever. Citric Acid is used as an excipient in medicines, as well as in the production of effervescent tablets and as a preservative in various formulations.
