The law of conservation of mass (from Lavoisier) states that mass can be neither created nor destroyed (but it may change its form into something that is not desired, such as heat with an engine) or that in a chemical reaction, the total mass of the reacting substances is equal to the total mass of products formed.
The anticholinergics and antispasmodics are a group of medicines that include the natural belladonna alkaloids (atropine, belladonna, hyoscyamine, and scopolamine) and related products. The anticholinergics and antispasmodics are used to relieve cramps or spasms of the stomach, intestines, and bladder. Some are used together with antacids or other medicines in the treatment of peptic ulcers. Others are used to prevent nausea, vomiting, and motion sickness.
Anticholinergic drugs block the action of the neurotransmitter acetylcholine on neurons in the brain. Thus, anticholinergic drugs are used to decrease tremors, rigidity, and drooling in patients under the age of 60.Unfortunately, acetylcholine is essential for proper neurotransmission in other areas of the brain.owever, anticholinergic drugs decrease the influence of acetylcholine in the body, either by preventing its production, blocking its receptor sites, or breaking it down chemically. Thus, anticholinergic drugs are used to decrease tremors, rigidity, and drooling in patients under the age of 60.
