Scientific communication is critical in ensuring transparency, credibility, and accessibility of medical knowledge. It encompasses non-promotional scientific dissemination, corporate communication, and promotional communication, each serving distinct audiences. The evolution of scientific communication includes digital transformation, open-access publishing, and patient-centric engagement. Companies must align their publication strategy with clinical and regulatory milestones while adhering to ethical guidelines such as ICMJE and GPP4. Digital tools, virtual symposia, and congress presentations have expanded the reach and impact of scientific communication. Challenges such as misinformation, ethical reporting, and regional regulatory compliance necessitate a structured and transparent approach.
