What are Barbiturates?
Barbiturates are a synthetic drug classified as a sedative hypnotic. Sedative hypnotics
depress or slow down the body's functions. Often these drugs are referred to as
tranquilizers, sleeping pills, or simply sedatives. Their effects range from reducing
anxiety to inducing sleep, depending on the amount taken.
There are several medical uses for barbiturates, besides controlling anxiety and sleep
disturbances. They are also used as a mild form of anesthesia and to control peptic
ulcers, high blood pressure and epileptic seizures.
Barbiturates are also a popular "street" drug. Commonly abused barbiturates
include amobarbital (Amytal), pentobarbital (Nembutal), and secobarbital (Seconal). These
drugs account for approximately one-third of all reported drug-related deaths, including
suicides and accidental drug poisonings. Accidental deaths may occur when a user takes one
dose, becomes confused, and unintentionally takes an additional or larger dose.
Using barbiturates in conjunction with alcohol is especially dangerous; because alcohol
is also a CNS (central nervous system) depressant, the effects aremultiplied and the risk
of death increases. Overdose deaths are more frequent when alcohol and barbiturates are
mixed, whether accidentally or deliberately.
Physical Effects
The effects of barbiturates are much like the effects of alcohol. Small amounts produce
calmness and relax muscles. Larger doses cause slurred speech, staggering, and poor
judgement. High doses can cause unconsciousness and death.
Effects of prescribed doses of short-acting barbiturates such as secobarbital generally
last 4 - 6 hours while effects from phenobarbital, a longer-acting barbiturate will last
from 8 -12 hours.
When taken, barbiturates slow down CNS activities such as heartbeat, breathing, brain
activities and reflexes. Because physical and mental responses are slowed down, it is
dangerous for users to drive a car or operate machinery while
under the influence of this drug. Other physical effects of barbiturates use include
difficulty in breathing, lethargy, allergic reactions, nausea, and dizziness.
Psychological Effects
Barbiturates produce a feeling of euphoria, tranquility and temporary relief of
anxiety. Regular and prolonged use of barbiturates induce tolerance-the need for higher
doses of a drug to produce the desired effect. Physical and psychological dependence and
withdrawal symptoms occur when use of the drug is abruptly stopped. Withdrawal symptoms
range from restlessness, insomnia and anxiety to convulsions and death.
Because the drug can easily pass through the placenta, use of barbiturates during
pregnancy may cause birth defects and behavioral problems in babies. Babies may be
physically dependent on the drug at birth and experience withdrawal symptoms shortly after
they are born. Their symptoms may include breathing problems, feeding difficulties,
disturbed sleep, sweating, irritability, and fever.
Signs and Symptoms
The following signs and symptoms may indicate the use of barbiturates.
Symptoms of alcohol intoxication with no odor on the breath, however many users combine
alcohol and barbiturates Slurred speech, lethargic Lack of
facial expression or animation
Activities such as frequent visits to several physicians to obtain prescriptions to
treat nervousness, insomnia, stress, or tension. Abusers may also visit numerous
pharmacists to have the prescription filled
