Pharmaceuticals are substances used to diagnose, treat, or prevent diseases and medical conditions. They play a crucial role in modern medicine, providing patients with the necessary tools to manage their health effectively. Common forms of pharmaceuticals include tablets, injections, and creams, each designed for specific therapeutic purposes. The development of pharmaceuticals involves extensive research and testing to ensure safety and efficacy. Regulatory bodies like the FDA oversee the approval process, ensuring that only safe and effective medications reach the market. This rigorous process helps maintain public trust in the healthcare system and promotes better health outcomes for patients.
