Parkinson’s Disease: In 1817, British physician Dr. James Parkinson published a case series documenting six patients suffering from “shaking palsy” (paralysis agitans), a chronic and progressive neurological disorder now known as Parkinson’s disease (PD). Parkinson’s disease occurs when nerve cells in the substantia nigra, a part of the brain, deteriorate or become damaged. These cells … Read more

Introduction Polymers are large molecules composed of repeating structural units (monomers) connected by covalent bonds. These macromolecules can be natural (e.g., proteins, polysaccharides) or synthetic (e.g., polyethylene, polylactic acid). The versatility of polymers, such as their ability to modify drug release profiles, has made them central to the development of advanced drug delivery systems, particularly … Read more
Controlled release formulations are designed to maintain therapeutic drug levels for an extended period. For successful formulation, the physicochemical and biological properties of the drug must meet specific criteria. I. Physicochemical Properties of Drugs 1. Aqueous Solubility: Drugs should have moderate solubility (not too high or too low). Relevance: Low solubility can limit the drug’s … Read more
Controlled release formulations can be designed using various mechanisms that regulate drug release. Three primary principles often employed are diffusion, dissolution, and ion exchange. Each approach involves different methodologies and is tailored to achieve a specific release profile. Controlled release formulations 1. Diffusion-Based Systems Diffusion-controlled drug delivery systems are among the most widely employed strategies … Read more
Controlled drug delivery systems (CDDS) are advanced systems designed to deliver therapeutic agents at a predetermined rate, locally or systemically, for a specified period. The goal is to achieve an optimized therapeutic response while minimizing side effects. This technology addresses the limitations of conventional drug delivery systems, such as fluctuating plasma drug levels and the … Read more
Maintaining accurate and up-to-date records in retail and wholesale drug stores is a legal and ethical requirement. It ensures the proper functioning of the pharmacy, compliance with regulatory guidelines, and safety in drug distribution. Record-keeping also facilitates accountability and traceability in the pharmaceutical supply chain. 1. Importance of Record Maintenance Legal Compliance: Adherence to the … Read more
Proprietary products refer to medicines that are trademarked and branded by specific pharmaceutical manufacturers. These are usually ready-made formulations available under a brand name, as opposed to generic or compound preparations. The dispensing of proprietary products in a pharmacy or drug store is governed by ethical and legal practices to ensure patient safety and therapeutic … Read more
