- Develop competence in creativity and entrepreneurial skills.
- Implement strategies based on gathered information to improve critical thinking, problem-solving, decision-making abilities, and conflict resolution to improve collaborative work.
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.
