Intro Pharmacology

• Functional modifiers can alter the biochemical and physiological activities of the cell. ​Majority of drugs. ex. ​analgesic and antipyretic
• Replenishers can supplement endogenous compounds which are insufficient. Ex. Disease hypothyroidism
• Diagnostic agents example is dobutamine it is an agent for pharmacologic stress test. It is a B1 ​agonist
• Chemotherapeutic agents is used to kill inhibit growth of foreign cells like pathogenic bacteria viruses fungi and cancer cells
• What the body does to the drug, p​harmakinetics deals with adme
• Drug dust to the body is called pharmacodynamics
• Triiodothyronine is more potent than tetraiodothyronine
• Thyroxine is the treatment for hypothyroidism, it undergoes isomerism to form t3 and t4.
• Preparation of choice for isomerism of thyroxine is levothyroxine. Dextrohyroxine has 4% of the activity of the level isomer so it needs more dose
