Effects on Ability to Drive and Use Machines

ability to drive and operate machines.
Squill has an irritant effect on the gastro-mucosa and large doses may give rise
to vomiting. The product may cause constipation.
Signs of overdosage due to morphine include pin-point pupils, depressed
respiration and coma. In severe poisoning there may be dilation of the pupils,
shock, severe respiratory depression and pulmonary oedema.
Treatment consists of general supportive therapy and may include gastric
lavage. In cases of respiratory depression naloxone hydrochloride, given
intravenously, can be used as an antidote
Morphine and related opioids depress the cough reflex, at least in part, by a
direct effect on the cough centre.
Squill irritates the gastric mucosa. It has a reflex expectorant action.
Opioids are readily absorbed from the gastrointestinal tract. Oral
bioavailability is low due to significant first pass metabolism in the liver.
Morphine is distributed throughout the body but mainly in the kidneys, liver,
lungs and spleen with lower concentrations in the brain and muscles.
Morphine diffuses across the placenta and traces also appear in milk and
sweat. The majority of a dose of morphine is conjugated with glucuronic acid
in the liver and gut to produce its major metabolite, morphine-3-glucuronide,
which is inactive and the active metabolite, morphine-6-glucuronide. Other
active metabolites include normorphine, codeine and morphine ethereal
sulphate. Mean plasma elimination half-lives of 1.7 hours for morphine and
2.4 - 6.7 hours for morphine-3-glucuronide have been reported. Up to 10% of
a dose of morphine may eventually be excreted as conjugates, through the bile
into faeces. The remainder is excreted in the urine. About 90% of total
morphine is excreted in 24 hours with traces in urine for 48 hours or more.
The glycosides of squill are poorly absorbed from the gastrointestinal tract.
No further pharmacokinetic data are available for squill.
