Study Notes

Dosage Forms

  • Dosage forms are the physical shapes of medicines. They are designed to make administering or using the drug easier.
  • Examples include tablets, capsules, injections, liquid dosage forms, suppositories, creams, and ointments.

Drug Products (Medicine)

  • A drug product is a medication formulated into a dosage form.
  • It includes the active ingredient(s) plus excipients (inactive ingredients). Excipients help with formulation, but have no therapeutic effect.

Drug Product Manufacturing Process

  • Drugs come from various sources, such as plants (like digitalis).
  • The active ingredient is isolated, packaged, and sent to a pharmaceutical company.
  • The company adds excipients to make the final product (like tablets, elixir, or ampoules).

Strength

  • Strength is the amount or concentration of the active ingredient in each dosage form.
  • For example, a tablet might contain 0.25 mg of digoxin.

Dose

  • Dose is the amount of active ingredient a patient takes at one time.
  • For example, taking two 0.25 mg tablets for a total dose of 0.5 mg.

Dose Regimen

  • Dose regimen is how often and when a medication is taken.
  • Example: two tablets daily, taken after meals

Drug Naming Conventions

  • Chemical name: The scientific name derived from the IUPAC system. It describes the chemical structure of the substance. Scientists who discovered the drug usually name medicines. Often a very long formula. An example given is N-acetyl para-aminophenol.
  • Official/Generic name: The official name listed in a pharmacopoeia; example* Paractemol*. given by highly specialized people in their field or by groups. Often shorter and simpler than the chemical formula. An example is acetaminophen.
  • Brand/Trade name: The name given to the product by the company that first marketed it. Examples: Panadol and Paramol. A drug can have several brand names.

Storage Conditions

  • Important for preserving the drug's quality and effectiveness.
  • Storage conditions include temperature, humidity, and exposure to light.
  • The container the medicine is kept in is important too.
  • Examples: "store between 15-30°C".

Expiration Date (Shelf-Life)

  • The date when the drug is expected to remain within its quality specifications. Usually about 90 percent of the drug remains in the same condition when stored correctly and is still usable by this date. This date helps determine the safety and efficacy.
