Study Notes

The Constituents of Organic Drugs

Organic drugs can be classified into active and inert constituents.
Active constituents can be pharmacologically active (affecting living tissues) or pharmaceutically active (causing chemical changes in preparations).
Active constituents can be single chemicals or mixtures.
- Single chemicals include: plant acids, alkaloids, neutral principles, toxalbumins, ferments, sugars, starches, and gums.
- Mixtures include: fixed oils, fats and waxes, volatile oils, resins, oleoresins, gum resins, and balsams.
- The last three are natural exudations from plants.
Alkaloids are naturally occurring plant compounds containing nitrogen. Uses include therapeutic and recreational purposes. Examples include caffeine, nicotine, and cocaine.
Glycosides are sugar ethers, often classified based on chemical nature with medicinal applications. Glycosides include alcohols, coumarines, etc.
Cardio glycosides are organic compounds containing a sugar called glycoside affecting heart muscles. Examples include digitoxin, digoxin, and gitoxin.
Minerals are important for health (e.g., calcium, copper, germanium, iodine, iron, manganese, phosphorus, potassium, and zinc).
Tannins are plant compounds with a harsh taste. They can have astringent effects (e.g., for varicose veins).
Amino acids are the building blocks of proteins. Examples include tryptophan which is essential for human life.

Inert Constituents

Inert constituents are parts of a drug with no pharmacological action. Examples include cellulose, wood, starch, albumen, fat, waxes, coloring matters, and other substances.
Inert constituents can modify or impact the action of active constituents.
These are used in formulations and surgeries. Examples include plant cellulose, lignin, suberin, and cutin, as well as animal products like keratin, chitin.
Cochineal is a coloring matter of plant origin.

Other Notes

Some plants contain vitamins like A, B, C, E, and K.
Mucilage are large sugar molecules acting as protective agents in the digestive tract
Volatile oils extracted from plants often used in essential oils.
Anthraquinones are irritant/stimulating constituents that act on the large intestine (e.g., aloe-emodin).
Flavonoids demonstrate anti-inflammatory, anti-bacterial, cardio health benefits.
Saponins have various actions like alteratives, diuretics, expectorants, etc.
Coumarins are found in certain plants, with actions such as blood thinning, anti-inflammatory, and antiseptic properties.
Secondary plant products, or inert constituents, can have effects that depend on context: beneficial or detrimental, or acting as an indicator of plant conditions/health.
