Pharmacology, Principles, and Pharmaceutics
Pharmacology Overview ● Drug: any chemical that affects the physical state of any living organism ● Pharmacology: study of drugs ● Pharmacokinetics: study of what happens to a drug once it enters the body
Names of Drugs ● Chemical name ● Generic name (nonproprietary name) ● Trade name
Chemical Name: The chemical name is a scientific name based on the compound's chemical structure and indicates the arrangement and position of atoms or atomic groups. Chemical names are long and are important to chemists, pharmacists, and researchers who work with drugs at the chemical level.
Generic Name (nonproprietary name): This is the official name given to a drug after it might have been found to be of therapeutic use.
Trade Name: The trade (also known as proprietary or brand name) is the name given to a drug by its manufacturer. A drug may have several brand names, depending on the number of manufacturers. Unlike chemical and generic names, brand names are easy to remember, short, catchy and most often suggestive of the drug component.
Phases of Drug Activity ● Pharmaceutical phase ● Pharmacokinetic phase ● Pharmacodynamic
Pharmaceutics ● Different drug dosage forms have different pharmaceutical properties. ● Dosage form determines drug dissolution rate. ● Dissolution – dissolving of solid dosage forms. ● Drug Absorption of various oral preparations – Table 2- ○ Liquids ○ Enteric coated ● Dosage forms ○ Enteral ○ Parenteral ○ Topical
Enteral Route ● The drug is absorbed into the systemic circulation through the oral or gastric mucosa or the small intestine. ○ Oral ○ Sublingual ○ Buccal ○ Rectal (can also be topical)
Parenteral Route ● Intravenous (fastest delivery into the blood circulation) ● Intramuscular (in a muscle) ● Subcutaneous (under the skin) ● Intradermal (injections administered into the dermis, just below the epidermis.) ● Intraarterial (directly into the arteries) ● Intrathecal (around the spinal cord) ● Intraarticular (into the joints) *** GIVEN BY DOCTORS
