Pharmaceutical formulation and drug delivery play a crucial role in the development of effective medications. Formulation involves the process of combining active pharmaceutical ingredients with suitable excipients to create a dosage form that ensures stability, bioavailability, and patient compliance. The selection of excipients is carefully considered to optimize drug release, absorption, and therapeutic efficacy. Drug delivery systems are designed to enhance drug targeting, reduce side effects, and improve patient outcomes. Various technologies such as liposomes, nanoparticles, and microparticles are utilized to facilitate controlled release or targeted delivery of drugs to specific tissues or cells within the body. Understanding the complexities of pharmaceutical formulation and drug delivery is essential for ensuring the safety and effectiveness of medication therapies in the healthcare industry.
