PARASYMPATHOLYTIC DRUGS Meaning and
Definition
-
Parasympatholytic drugs, also known as anticholinergic drugs or muscarinic antagonists, are a class of medications that block the activity of the parasympathetic nervous system. The parasympathetic nervous system is one of the divisions of the autonomic nervous system, responsible for regulating various involuntary body functions such as heart rate, digestion, and glandular secretion.
These drugs work by binding to the receptors for the neurotransmitter acetylcholine in the parasympathetic nervous system. By blocking the binding of acetylcholine to these receptors, parasympatholytic drugs prevent the normal actions of the neurotransmitter, effectively inhibiting parasympathetic nerve activity.
The effects of parasympatholytic drugs can vary depending on the specific drug and dosage used. Generally, these medications cause a relaxation or inhibition of various smooth muscles, such as those in the gastrointestinal tract, urinary bladder, and bronchial tubes. They also decrease the production of saliva and other glandular secretions, leading to a dry mouth and reduced sweating.
Parasympatholytic drugs are used for a variety of therapeutic purposes. They can be prescribed to treat conditions such as overactive bladder, chronic obstructive pulmonary disease (COPD), irritable bowel syndrome (IBS), and gastrointestinal spasms. Additionally, they are sometimes used during surgery to induce relaxation of skeletal muscles, prevent excessive secretions, and inhibit certain reflexes.
However, it is important to note that the use of parasympatholytic drugs can also be associated with various side effects, such as blurred vision, constipation, urinary retention, confusion, and increased heart rate. These medications should be used with caution, and dosage adjustments may be necessary depending
