    Introduction

    • Pharmaceutics encompasses dispensing and pharmaceutical technology.
    • Dispensing involves supplying medication according to a prescription, clarifying prescriber wishes, preparing, and labeling the medicine, and compounding and utilizing relevant information.
    • Pharmaceutical technology emphasizes the technology for formulating and preparing dosage forms.
    • Dosage forms deliver drugs to the site of action within the body and can be classified by preparation route or nature.

    Routes of Administration

    • Oral Route:

      • Drug administration through the gastrointestinal tract (GIT).
      • Most common route.
      • Suitable for most drugs, except those rapidly inactivated in the GIT.
      • Drugs can be degraded by stomach pH or digestive enzymes.
      • Can be unsuitable in case of vomiting or unconsciousness.
      • Absorption is slow and can be incomplete
      • Problems occur from the "first-pass effect."

    • Buccal and Sublingual Route:

      • Administration in the buccal cavity or under the tongue.
      • Avoids some oral route problems.
      • Rapid drug absorption due to rich blood capillaries.

    • Rectal Route:

      • Drug insertion in the rectum.
      • Absorption mainly into systemic circulation.
      • Suitable for drugs causing GI irritation or for comatosed patients or in case of vomiting.

    • Transdermal Route:

      • Drug absorption through the skin.
      • Useful for drugs with short half-lives.

    • Parenteral Route:

      • Drug administration by injection.
      • Intravenous (IV): Delivers drugs directly into circulation.
      • Injection volume varies.
      • Subcutaneous (SC) and intramuscular (IM) injections involve slower absorption.
      • Other routes include intra-articular, intraocular, intracardiac, and intracisternal.

    • Inhalational Route:

      • Drug administration via the respiratory system.
      • High blood flow and large alveolar surface area allow rapid absorption of drugs.
      • Suitable for anaesthetic gases, volatile liquids, and aerosolized drugs.
      • Nasal route is a potential systemic administration route.

    • Those Intended for Local Effect:

      • Oral route: Drugs are not absorbed, acting locally on the GIT. Examples include adsorbents, antimicrobials, and antacids.
      • Topical route: Drugs are applied to the epithelium, effecting localized action at the application site. Examples include application to skin, cornea, nasal, rectal, vaginal, and urethral mucosa.

    Pharmaceutical Calculations

    • Calculations use master formulas (MF) to determine dispensing factors (DF) needed for required amounts.
    • DF = (amount required) / (total amount in MF)
    • Weight and measure systems (Imperial/Apothecaries, Metric/Apothecaries, Avoirdupois) and conversions between them are crucial. Grains frequently are the intermediary unit.
    • Important examples include calculating quantities of ingredients for specific dosage forms from master formulas.

    Weights and Measures

    • (Metric system, including units of length, volume, and weight. Conversions between metric and other systems are crucial)
    • (Apothecaries systems conversions, and relationships between units in these systems)

    Additional Information (Examples)

    • Various examples of calculations are illustrated, including conversions between units and calculations for specific solutions, mixtures, and ointments.
