Study Notes
Pharmacology Overview
- Pharmacology examines how drugs interact with biological systems.
- Pharmaceuticals possessing medicinal properties are considered to have therapeutic benefits.
- The field primarily investigates the effects, mechanisms, and therapeutic uses of drugs.
Pharmacokinetics
- Focuses on the absorption, distribution, metabolism, and excretion of drugs within the body.
- Addresses how the body processes a drug over time, influencing its efficacy and dosing.
Cholinergic Blocking Drugs
- These drugs primarily act to inhibit the effects of acetylcholine in the nervous system.
- They target cholinergic receptors, specifically nicotinic and muscarinic receptors.
Receptor Locations
- Nicotinic receptors are found at the neuromuscular junctions and autonomic ganglia.
- Muscarinic receptors are located in various tissues, including smooth and cardiac muscles, as well as glands.
Effects of Antimuscarinic and Antinicotinic Agents
- Antimuscarinic agents can induce symptoms such as dry mouth, blurred vision, and urinary retention.
- Antinicotinic agents may cause muscle relaxation and decreased muscle tone.
Sources of Naturally Occurring Antimuscarinics and Antinicotinics
- Naturally occurring antimuscarinics have been derived from plants such as Atropa belladonna (deadly nightshade).
- Naturally occurring antinicotinics can be sourced from the tobacco plant (Nicotiana tabacum).
Functions in the Somatic Nervous System
- Cholinergic blocking drugs primarily function to relax smooth muscle, reduce secretions, and decrease heart rate.
Potential Effects of Antimuscarinic and Antinicotinic Agents
- These agents can potentially lead to increased heart rate, reduced muscle contraction, and various side effects depending on receptor activity.
