• Most widely used surfactant: Sodium lauryl sulfate, used to stabilize suspensions by reducing surface tension.

Summary: Alternative medicine includes acupuncture (needle-based), Ayurveda, chiropractic, and aromatherapy. Pharmaceutical suspensions require good re-suspendability and slow settling. Rifampicin colors urine orange-red; Zidovudine may cause anemia. Omeprazole inhibits acid secretion in H. pylori treatment. Hydralazine is preferred for hypertensive emergencies. Procurement methods vary by urgency and supplier availability.

1. Cosmetics and Dermatological Products

a) Definitions and Scope

• Dermatological products: Medicated formulations intended for treatment or prevention of skin diseases.

b) Classification of Cosmetics

c) Dermatological Product Types

• Topical preparations: creams, ointments, gels, lotions, powders.
• Routes of application: primarily topical; some may be systemic.
• Formulation considerations: drug solubility, skin penetration, stability, patient acceptability.

d) Key Ingredients in Cosmetics and Dermatological Products

• Emollients: soften and smooth skin (e.g., petrolatum, lanolin).
• Humectants: attract water to skin (e.g., glycerin, urea).
• Preservatives: prevent microbial growth (e.g., parabens, phenoxyethanol).
• Fragrances: provide scent; may cause allergies.
• Sunscreens: chemical (e.g., oxybenzone) or physical blockers (e.g., zinc oxide).

e) Formulation Principles

• Ointments: greasy, occlusive, good for dry skin.
• Creams: emulsions, less greasy, suitable for moist skin.
• Lotions: fluid, easy to spread, for large areas.
• Gels: water-based, non-greasy, cooling effect.

f) Safety and Regulatory Aspects

• Cosmetics must be safe for intended use; no therapeutic claims allowed.
• Dermatological products are regulated as drugs; require efficacy and safety data.

11. Chelation Effects on Tetracycline

• Chelation with Ca, Al, Fe, Mg ions reduces absorption of tetracycline.
• No significant effect on distribution, metabolism, or excretion.

12. Pharmacokinetic Definitions

Key point: Bioavailability measures the fraction of active drug reaching systemic circulation intact.

1. Dosage Forms

Dosage forms refer to the physical form in which a drug is produced and administered. They influence the drug's stability, release, absorption, and patient compliance.

2. Routes of Administration

The route of administration determines the onset, intensity, and duration of drug action. It affects bioavailability and patient compliance.

3. Key Concepts

• Bioavailability: Fraction of administered drug reaching systemic circulation. IV route has 100% bioavailability.
• First-pass metabolism: Drug metabolism in the liver before reaching systemic circulation, reducing bioavailability (notable in oral route).
• Pharmacodynamics: What the drug does to the body.
• Pharmacokinetics: What the body does to the drug (absorption, distribution, metabolism, excretion).

To remember: The choice of dosage form and route depends on the drug’s properties, desired onset of action, and patient factors.

4. Practical Considerations in Pharmacy

• During drug receiving, check type, quantity, batch number, but indication is not required.
• Drug and Therapeutics Committee (DTC) functions: drug selection, formulary preparation, identifying drug use problems; purchasing is not a direct function.
• Formulary systems: Open formulary allows non-formulary drugs; management should limit non-formulary drugs to control costs.
• Good dispensing practices include reading prescriptions carefully, referring to treatment guidelines, and switching brands to generics when appropriate.
• Most common drug sources: synthetic, followed by plant, animal, and genetic engineering.

5. HIV Drug Classes (For Context)

6. Side Effects to Note

• Appetite loss: Abacavir (ABC)
• Mood changes, depression, anxiety: Efavirenz (EFV)

> The route of administration critically affects drug bioavailability and therapeutic effect; IV administration ensures 100% bioavailability.

1. Drug Storage and Stability

a) Key Concepts in Drug Quality and Storage

• Drug quality problems include physical changes such as:

  • Presence of suspended particles in solutions
  • Color changes
  • Melting of suppositories at room temperature
    Cost of the drug is NOT a drug quality problem.

• Essential drugs availability:
  Some drugs must be available year-round in hospitals/health centers, e.g., ORS (Oral Rehydration Salts).

• Drug types:

  • Traditional medicine: Indigenous or culturally rooted remedies.
  • Alternative medicine: Non-mainstream practices used instead of conventional medicine.
  • Western medicine: Conventional, evidence-based medicine.

b) Drug Supply Chain Terms

c) Dosage Forms and Administration Routes

• Otic dosage form: Drugs administered through the ears.
• Subcutaneous dosage form: Drugs administered under the skin.
• Other routes:
  • Transdermal: Through the skin.
  • Topical: Applied on the skin surface.
  • Rectal: Administered via the rectum.

d) Pharmacokinetics Sequence

The correct order of pharmacokinetics processes is:
Absorption → Distribution → Metabolism → Excretion

e) Compounding and Dispensing

• When compounding at a small scale, mandatory steps include:

  • Selecting the right container
  • Labeling appropriately
  • Following correct compounding procedures
    Do NOT place preparations in cold containers without removing previous labels.

• Safest dispensing method for hospitalized patients:
  Unit dose dispensing system (individual doses prepared and labeled).
