Pharmaceuticals play a vital role in global healthcare, ensuring that essential medications reach those in need through service distribution, retail, and marketing. Service distribution focuses on the efficient supply chain that connects manufacturers with hospitals, pharmacies, and healthcare providers, ensuring medicines are available when and where they are needed. Retail pharmacies serve as the direct link between patients and medications, providing not just prescription drugs but also over-the-counter products, health consultations, and personalized care. Meanwhile, pharmaceutical marketing helps educate both healthcare professionals and consumers about new treatments, drug safety, and proper medication use, balancing compliance with industry regulations while promoting better healthcare outcomes.
