Customized drug delivery system and factors to be considered for developing personalized medication

Customized drug delivery refers to the use of tailored drug delivery systems that can be optimized for the specific needs of individual patients. This approach involves designing drug formulations that can selectively target the diseased tissues or cells, while minimizing exposure to healthy tissues and cells. Customized drug delivery can enhance the efficacy and safety of drugs, and can be particularly useful for patients who have unique drug responses, such as those with genetic or metabolic variations.



To develop personalized medication, several factors need to be considered, including:

  1. Patient characteristics: Personalized medication should take into account patient characteristics such as age, gender, weight, medical history, and genetic makeup. These factors can influence drug absorption, distribution, metabolism, and elimination, and can affect the drug's efficacy and toxicity.

  2. Disease characteristics: The type and severity of the disease, as well as the location and extent of the affected tissue, can influence the drug delivery strategy. For example, a drug delivery system that targets the brain may need to cross the blood-brain barrier, while a system that targets the lungs may need to withstand the harsh environment of the respiratory system.

  3. Drug properties: The physicochemical properties of the drug, such as solubility, stability, and bioavailability, can affect its delivery and efficacy. Personalized medication may involve modifying the drug's properties or using drug delivery systems that can enhance its therapeutic potential.

  4. Delivery route: The route of drug administration can affect drug bioavailability, distribution, and elimination. Personalized medication may involve selecting the optimal route of administration, such as oral, intravenous, or inhalation, based on the patient's condition and preferences.

  5. Safety and toxicity: Personalized medication should take into account the potential for adverse effects, drug interactions, and toxicity. Drug delivery systems that can minimize off-target effects or improve drug tolerability may be needed.

Overall, customized drug delivery offers the potential to optimize drug therapy for individual patients and improve treatment outcomes. However, the development of personalized medication requires a thorough understanding of the patient's needs and the underlying disease mechanisms, as well as innovative drug delivery strategies that can address these needs.

ANTIOXIDANTS: In Pharmaceutical Formulation

Image
Introduction: Chemically they are reducing agents. They oxidize themselves and prevent oxidation of API. A substance that inhibits oxidation is called antioxidants. The effectiveness of antioxidant can depend on the concentration used and pH of solution. Examples:  Ascorbic acid,  butylated hydroxy anisole (BHA),  butylated hydroxyl toluene (BHT) Oxidation is a chemical reaction involving the loss of electrons or an increase in oxidation state. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions. When the chain reaction occurs in a cell, it can cause damage or death to the cell. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. The following are some of the qualities of an ideal anti-oxidant: It should be readily soluble or dispersible in the medium. It should be effective in low concentration. It should be non-toxic. It should be non-irrita

3. Development of working hypothesis:

Image
After extensive literature survey, researcher should state in clear terms the working hypothesis or hypotheses. Working hypothesis is tentative assumption made in order to draw out and test its logical or empirical consequences. As such the manner in which research hypotheses are developed is particularly important since they provide the focal point for research. They also affect the manner in which tests must be conducted in the analysis of data and indirectly the quality of data which is required for the analysis. In most types of research, the development of working hypothesis plays an important role. Hypothesis should be very specific and limited to the piece of research in hand because it has to be tested. The role of the hypothesis is to guide the researcher by delimiting the area of research and to keep him on the right track. It sharpens his thinking and focuses attention on the more important facets of the problem. It also indicates the type of data required
