What does spasmolytic mean?
A spasmolytic is something that relaxes smooth muscle, particularly muscle in the walls of the digestive tract, blood vessels, or other hollow organs. The term may describe a medicine's action or refer to the medicine itself. Such agents are used to reduce painful contractions, cramping, or spasms involving smooth muscle, although their exact effects and clinical uses depend on the substance involved. Spasmolytic is a formal medical term and is somewhat less common than the synonymous term “antispasmodic.” Its name reflects its function: the element “-lytic” comes from a Greek root associated with loosening or dissolving, while the first part of the word refers to a spasm. The term is useful in medicine and pharmacology because it identifies a characteristic action rather than a single chemical class or particular condition.
Causing the relaxation of smooth muscle, especially so as to relieve a muscular spasm.
"The drug is used for its spasmolytic effect on gastrointestinal smooth muscle."
Often encountered in technical medical and pharmacological descriptions.
A drug or other substance that relaxes smooth muscle and relieves muscular contractions or cramping.
"The emergency team used a spasmolytic to treat the patient's severe abdominal spasm."
Usually refers to a pharmaceutical agent, though it can denote any substance having the stated action.
The plural is used when referring to multiple spasmolytic drugs or agents.
"Several spasmolytics are used to relieve gastrointestinal cramps."
The suffix “-lytic” points to loosening: a spasmolytic releases smooth muscle from contraction.

Where does spasmolytic come from?
The word combines Greek spasmos, meaning a drawing or contraction, with the suffix -lytic, associated with lysis, “a loosening.” These elements reflect the word's original medical sense of relieving or loosening muscular contractions. English acquired the term during the development of scientific medicine, and related medical vocabulary includes “spasm,” “spasmodic,” and “spastic.”
