Study Notes

Physical Description

  • Most drugs are solid materials, either crystalline or amorphous compounds.
  • Purity is crucial for identification and evaluation of chemical, physical, and biological properties.
  • Drugs can exist as solids, liquids, or gases for therapeutic use.

Microscopic Examination

  • Provides insights on particle size and size range of raw materials.
  • Photomicrographs help identify formulation processing issues linked to changes in particle or crystal characteristics.

Heat of Vaporization

  • Defines the heat absorbed when vaporizing 1 gram of liquid, measured in calories.
  • Molecular movement is temperature-dependent.

Melting Point Depression

  • A pure substance has a specific melting point/range, used to assess purity and compatibility with other substances.

Phase Rule

  • A phase diagram shows the melting point in relation to the composition of two or three-component systems.
  • Visualizes solid and liquid phase existence in binary, ternary, and other mixtures.

Particle Size

  • Affects dissolution rate, bioavailability, content uniformity, as well as taste, texture, color, and stability.
  • Influences flow characteristics and sedimentation rates.

Polymorphism

  • Different polymorphic forms can exhibit varying physicochemical properties like melting point and solubility.

Solubility

  • A key physicochemical property, crucial for the therapeutic efficacy of a drug.
  • A drug must have some aqueous solubility to be effective.

Solubility and Particle Size

  • Reducing particle size can lead to increased solubility.

Solubility and pH

  • Adjusting pH of the solvent can enhance solubility of the drug substance.

Membrane Permeability

  • Drug molecules must traverse biological membranes to elicit a response.
  • Biological membranes function as lipid barriers, restricting most drugs while allowing lipid-soluble substances to cross via passive diffusion.

Dissolution

  • Dissolution rate refers to how long it takes for a drug to dissolve in fluids at the site of absorption.
  • This process is often the rate-limiting step in the drug absorption phase.

Partition Coefficient

  • The oil-water partition coefficient quantifies a molecule's lipophilicity, indicating its affinity for either hydrophilic (water-based) or lipophilic (fat-based) environments.

Organic Esters in Pharmacy

  • Drugs can exist as either a base form or ester form, with dosage potentially based on either formulation.
  • Esters rank as the second most significant acid derivatives in the pharmaceutical industry, following salts.
  • Preparation of esters serves various purposes:
    • Solubility: Enhances the solubility of drugs in biological fluids.
    • Stability: Improves the stability of drug compounds during storage and after administration.
    • Resistance to Degradation: Offers protection from breakdown when in the body, ensuring therapeutic effectiveness.
    • Prodrug Utilization: Certain esters function as prodrugs, which become active only after metabolism.

Potency-Designated Active Pharmaceutical Ingredients

  • Potency-designated drugs refer to bulk substances or active pharmaceutical ingredients (APIs) that are not comprised of 100% active drug.
  • Knowing the assayed potency of an ingredient is crucial for making accurate calculations to obtain the correct dosage in formulations.

Complex Organic Molecules

  • The majority of complex molecules and biotech products are classified as proteins.
  • Proteins are unstable and require special handling to maintain their efficacy and integrity.
  • Protein drugs are extremely potent and typically utilized in low concentrations.
  • A significant portion of manufactured products and compounded preparations consists of excipients such as vehicles, buffers, and stabilizers, rather than the active drug itself.

Drug-Plastic Interaction

  • PVC (polyvinyl chloride) bags are commonly used for drug storage and infusion.
  • DEHP (di-ethyl-hexyl-phthalate) is a plasticizer found in PVC that can leach into medications.

Effects of Plastic on Drugs

  • Leaching: The process where components of the bag material migrate into the drug solution, potentially altering drug efficacy and safety.
  • Adsorption: Some drugs may adhere to the surface of the plastic, leading to reduced drug availability and dosage discrepancies.
  • Absorption: Certain drugs may permeate through the plastic wall, further impacting the amount of drug delivered to patients.

Example Drugs Affected

  • Diazepam: A commonly used anti-anxiety medication that can interact negatively with PVC bags, compromising its delivery.
  • Isosorbide Dinitrate: A medication for angina that is also susceptible to interactions with PVC, potentially affecting its therapeutic effectiveness.

Common Preservatives in Pharmaceuticals

  • Benzoic Acid: Utilized at concentrations of 0.1% to 0.2% to prevent microbial growth.
  • Sodium Benzoate: Similar to benzoic acid, employed at 0.1% to 0.2% for its antimicrobial properties.
  • Alcohol: Effective as a preservative in higher concentrations, typically ranging from 15% to 20%.
  • Phenylmercuric Nitrate & Acetate: Rarely used, at very low concentrations of 0.002% to 0.01%, due to potential toxicity.
  • Phenol: A commonly used preservative at concentrations varying from 0.1% to 0.5%, known for its antiseptic qualities.
  • Cresol: Also serves as a preservative, employed at concentrations of 0.1% to 0.5%, effective against bacteria.
  • Chlorobutanol: Used in a set concentration of 0.5% for its preservative effectiveness.
  • Benzalkonium Chloride: At very low concentrations (0.002% to 0.01%), it performs as a potent antimicrobial agent.
  • Methyl & Propylparaben Combinations: Seen in concentrations of 0.1% to 0.2%, these are used to inhibit a broad spectrum of fungi and bacteria.

Preservative Concentration Overview

  • Benzoic Acid: Effective concentration between 0.1% and 0.2%, commonly used for its antimicrobial properties.
  • Sodium Benzoate: Similar range to benzoic acid (0.1% - 0.2%); functions as a preservative in acidic foods and beverages.
  • Alcohol: Concentration levels range from 15% to 20%; utilized for its antibacterial and antifungal properties.
  • Phenylmercuric Nitrate & Acetate: Low concentration range of 0.002% - 0.01%; historically used in some cosmetic and pharmaceutical applications but with declining usage due to safety concerns.
  • Phenol: Utilized at concentrations between 0.1% and 0.5%; effective as a disinfectant and preservative.
  • Cresol: Similar to phenol, used at 0.1% - 0.5%; provides antiseptic properties and is effective in controlling bacteria and fungi.
  • Chlorobutanol: Preservative used at a concentration of 0.5%; known for its effectiveness in topical formulations.
  • Benzalkonium Chloride: Utilized at very low concentrations (0.002% - 0.01%); often found in antiseptics and disinfectant formulations.
  • Combinations of Methyl & Propylparaben: Effective as a preservative in concentrations of 0.1% - 0.2%; widely used in cosmetics and personal care products due to their antibacterial properties.
