Presentation for the word
“sedative”
By :
Ashwin Shah
Passage 2
• The drugs most commonly prescribed to treat the symptoms of
Multiple Sclerosis include baclofen (Lioresal) and tizanidine
(Zanaflex) which relieve both spasticity and muscle spasms but
often only partially and sometimes not at all. Both are sedatives,
so they cause drowsiness; additional side effects include dry
mouth and muscle weakness. The latter is especially
problematic for people with Multiple Sclerosis, whose muscles
get weaker as the disease progresses.

Passage 1
Pharmaceutical firms (PF) attempt to produce
consistently potent and reliable drugs from
hemp. By the 1930s at least two American
companies -- Parke-Davis and Eli Lilly -- were
selling standardized extracts of marijuana for
use as an analgesic, an antispasmodic and
sedative. Another manufacturer, Grimault &
Company, marketed marijuana cigarettes as a
remedy for asthma.
