Contraindication Notes:
Lorazepam should not be given to patients with a previous sensitivity to benzodiazepines or with acute narrow-angle glaucoma and myasthenia gravis.
Lorazepam is a short-acting tranquilizer of the benzodiazepine group. It is an agonist at benzodiazepine receptors in the CNS. It exerts a depressant action on the CNS, which may be mediated by potentiating the inhibitory actions of GABA (gamma amino butyric acid) in the CNS. This will result in diminution of the ascending activating systems, particularly the serotonergic and noradrenergic pathway from brain stem or the mid-brain to the cerebral cortex.
Lorazepam may potentiate the central depressant effect when combined with other drugs with central depressant action. Such drugs include alcohol, general anesthetics, tricyclic antidepressants and monoamine oxidase inhibitors.
Adverse reactions are usually observed at the beginning of therapy and generally disappeared on continued medication or upon decreasing the dose. The most frequent adverse reactions of Lorazepam are sedation followed by dizziness, weakness and unsteadiness. Less frequent adverse reactions are disorientation, depression, nausea, change in appetite, headache, sleep disturbance, agitation, dermatological symptoms, eye-function disturbance, together with various gastrointestinal symptoms and autonomic manifestations.
Overdosage of Lorazepam is usually manifested by varying degrees of central nervous system depression ranging from drowsiness to coma. In mild cases, symptoms include drowsiness, mental confusion and lethargy. In more serious cases and especially when other drugs or alcohol were ingested, symptoms may include ataxia, hypotonia, hypotension, hypnotic states (stages I to III), coma.
Safety of Lorazepam in pregnancy has not been established. Because the use of this drug is rarely a matter of urgency, the use of Lorazepam during this period should almost always be avoided.It is not known whether oral Lorazepam is excreted in human milk like other benzodiazepine tranquilizers. As a general rule, nursing should not be undertaken while a patient is on a drug since many drugs are excreted in human milk.
In patients with depression accompanying anxiety, a possibility for suicide should be borne in mind. For elderly or debilitated patients, the initial daily dosage should not exceed 2 mg in order to avoid over sedation. The usual precautions for treating patients with impaired renal or hepatic function and with acute and chronic pulmonary insufficiency should be observed. Use of Lorazepam for prolonged period and gastric patients requires caution and there should be frequent monitoring for symptoms of upper gastrointestinal disease. Machineries should be avoided during taking Lorazepam.
