Motrin







Overview

Motrin, known generically as ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) widely used to relieve pain, reduce inflammation, and lower fever. Available over-the-counter in tablets, capsules, chewable tablets, and liquid suspensions, it works by inhibiting prostaglandin production, which causes pain and inflammation.

History of Development and Approval

Developed by Boots in the 1960s and later marketed by Johnson & Johnson as Motrin, ibuprofen received FDA approval in 1974 for prescription use and in 1984 for over-the-counter use. Its efficacy and safety, backed by extensive clinical research, have made it a trusted choice for pain and inflammation relief.

Key Benefits

  • Pain Relief: Effectively manages mild to moderate pain from headaches, muscle aches, menstrual cramps, and arthritis.
  • Anti-Inflammatory: Reduces inflammation in conditions like arthritis and injuries.
  • Fever Reduction: Lowers fever associated with colds, flu, or infections.
  • Versatile Forms: Tablets, capsules, chewables, and liquids cater to various age groups and preferences.
  • Rapid Action: Provides relief within 30–60 minutes.

Unique Properties

Motrin’s inhibition of cyclooxygenase (COX) enzymes reduces prostaglandin synthesis, effectively targeting pain and inflammation. Its multiple formulations and over-the-counter availability make it accessible and convenient for a wide range of users.

Comparison with Similar Medications

Compared to other NSAIDs, Motrin offers:

  • Balanced Efficacy: Comparable pain relief to naproxen but faster onset.
  • Flexible Dosing: Suitable for short-term and chronic use with proper guidance.
  • Pediatric Options: Liquid and chewable forms for children.
