Study Notes
Pharmacology Concepts
- Toxicity: The degree to which a substance can cause harm or damage to living organisms, including humans.
Routes of Administration
- Parenteral Route: A method of administering drugs through injection, avoiding the gastrointestinal tract, and allowing for faster absorption.
- Advantages of Parenteral Route:
- Rapid onset of action
- Higher bioavailability
- Suitable for emergency situations
- Disadvantages of Parenteral Route:
- Invasive and painful
- Risk of infection and allergic reactions
- Requires specialized training and equipment
Histamine and Anti-Histamine
- Histamine: A neurotransmitter involved in local immune responses, regulating physiological functions such as sleep, appetite, and blood pressure.
- Anti-Histamine: A medication that counteracts the effects of histamine, used to treat allergies, itching, and other conditions.
Neurotransmitters
- Neurotransmitter: A chemical messenger that transmits signals between neurons in the nervous system, influencing various physiological and psychological processes.
Treatment of Diarrhea
- Prototype Drugs: Medications that serve as a model for treating a specific condition, in this case, diarrhea.
- Examples of prototype drugs used to treat diarrhea:
- Loperamide (Imodium)
- Diphenoxylate (Lomotil)
