Study Notes

British Pharmacopoeia (BP)

Most widely used pharmacopoeia globally
Responsibility lies with the General Medical Council (GMC) since 1858
Contains complete drug monographs
Focuses on quality control and assurance for pharmaceutical production
Includes quality control tests for various dosage forms
Provides identification and analytical tests for drugs

British National Formulary (BNF)

National formulary for medicines in the United Kingdom
Co-supervised by the GMC and the Royal Pharmaceutical Society of Great Britain
Used for registration examinations in the UAE and the UK
Provides information on clinical and pharmacological aspects of drugs
Includes details on prescription policies, refilling, and prescription handling

British Pharmacopoeia Codex

First published in 1903 by the Royal Pharmaceutical Society of Great Britain
Designed for medical practitioners and dispensing pharmacists
Covers dispensing methods for different types of medicines
Includes dispensing techniques like unit dose and multi-dose dispensing
Offers a comprehensive understanding of pharmacological aspects of drugs

Ibn-Zuhar (1162-1249)

Pioneered modern anesthesiology by describing the use of inhaled anesthetics
Made notable contributions to neuropharmacology, including clinical, neuro, cardio, cancer, reproduction, medical, and toxicology branches.
Authored an early pharmacopoeia printed in 1491

Abu Ali Sina (980-1037)

Renowned physician, chemist, and astronomer
Wrote over 450 treatises on various scientific subjects, including 40 on medicine
"The Canon of Medicine" was used extensively as a medical textbook
First to describe the diagnosis procedure in detail
Classified various psychiatric diseases like depression, mania, insomnia, and dementia
Provided detailed descriptions of paralysis
Identified risk factors for clinical trials
First to describe steam distillation

Al Biruni (973-1050)

Prominent pharmacist, physician, and geologist
Contributed to the development and advancement of pharmacy
His work included the concept of osmotic pressure, which prevents osmosis
Established that body fluids like blood and tears have an osmotic pressure equivalent to a 0.9% NaCl solution

Isotonic Solutions

Described as solutions with equal osmotic pressure and ion concentrations to their comparative solution
Isotonic to body fluids, which is equivalent to a 0.9% NaCl solution
Help balance electrolytes and maintain physiological conditions
Applications in physiological experiments, tissue culture, and wound flushing
Used intravenously for patients unable to take fluids orally
Useful for nasal washes to relieve common cold symptoms

Hypotonic Solutions

Solutions with lower osmotic pressure than body fluids
Can cause hemolysis of red blood cells upon being added to the body's system

Hypertonic Solutions

Solutions with higher osmotic pressure than body fluids
Have a drawing effect on water from body tissues
Can cause shrinkage of body tissues and complications

Liniments

Alcoholic or oleaginous preparations of medications intended for external use on the skin
Available in liquid or semi-liquid forms
Can be utilized as solutions, suspensions, or emulsions
Used for their rubefacient action, irritant effects, and counter-irritant properties
Penetrate the skin for therapeutic benefit

Vehicle Types for Liniments

Alcoholic or hydro-alcoholic vehicles are preferred for rubefacient, counter-irritant, and penetrating actions
Oleaginous vehicles are used when massage is desired as they are less irritating

Liniment Precautions

Should not be applied to broken skin due to potential irritation
Storage: Tightly closed containers labeled “For external use only” and “Shake the bottle well before use”

Aerosols

Pressurized dosage forms containing one or more active ingredients
Release a fine dispersion of solid and liquid particles upon actuation
Consist of: Propellant, Container, Valve assembly and actuator, Product concentrate

Propellants

Create pressure within the container and propel the product
Examples: Butane, isobutane, chlorofluorocarbons (difluoroethane, dichlorotetrafluoroethane)

Containers

Materials commonly used: Tin plate, aluminum, stainless steel, glass

Effervescent Tablets

Contain sodium bicarbonate, citric acid, and tartaric acid in addition to active medications
React with water to release carbon dioxide, producing effervescence and tablet disintegration
Examples: Disprin, Cac 1000

Chewable Tablets

Designed to be broken and chewed before ingestion
Suitable for children and adults who have difficulty swallowing
Examples: Antacids, multivitamin tablets

Sustained Release Tablets

Prolong the duration of drug action after oral administration
Examples: Dicloran, Voltral

Tablet Formulation

Generally consist of active ingredients mixed with inert substances called excipients or additives

Excipient Functions

Diluents: Increase tablet bulk
Binders: Hold tablet ingredients together
Disintegrating agents: Aid in tablet breakdown in the gastrointestinal tract
Lubricants: Prevent tablet sticking to equipment during production
Coloring agents: Enhance tablet appearance
Flavoring agents: Improve tablet palatability
Sweetening agents: Improve tablet taste
Preservatives: Extend shelf life

Tablet Preparation Methods

Direct compression
Dry granulation/Slugging
Wet granulation

Tablet Coating

Deposition of a material on tablets to modify their properties

Objectives of Tablet Coating

Improved appearance, taste, and stability
Protection from environmental factors like air and humidity
