Concept of First Generation and Second Generation Medications Essay Paper
1. Using antihistamines as an example, briefly explain the concept of first generation and second-generation medications and why antihistamines are significantly different from others
- First generation antihistamines were developed in the 1940s and 1950s.
- These drugs are known to cause sedation and drowsiness, and are often used as sleep aids.
- They are also known to cause other side effects, such as dry mouth, blurred vision, constipation, and urinary retention.
- Second generation antihistamines were developed in the 1980s and 1990s.
- These drugs are designed to be less sedating than first generation antihistamines.
- They are also known to cause fewer side effects, such as dry mouth and blurred vision.
Antihistamines are drugs used to treat allergies and allergic reactions by blocking the action of histamine, a chemical released by the body in response to allergens. They are available in two generations, with the first generation being more sedating and causing more side effects than the second generation. Antihistamines are significantly different from other medications because they target histamine receptors, which are found throughout the body, and are not effective for all types of allergies and allergic reactions.
