Purata tablets are indicated for the short-term relief (2-4 weeks) only of anxiety that is severe, disabling or subjecting the individual to unacceptable distress, occurring alone or in association with insomnia or short term psychosomatic, organic or psychotic illness.
The use of Purata to treat short-term 'mild' anxiety is considered to be inappropriate and unsuitable.
Posology
All patients taking Purata should be carefully monitored and routine repeat prescriptions should be avoided. Patients who have taken benzodiazepines for a long time may require an extended withdrawal period during which doses are reduced. Long-term chronic use is not recommended.
Adults
Severe anxiety: The recommended dosage is 15-30 mg three or four times daily.
Insomnia associated with anxiety
Most patients need a dose of 15-25 mg but some patients may need up to 50 mg. The dose should be taken one hour before retiring.
Elderly patients and those who are particularly sensitive to benzodiazepines. The recommended dosage is 10-20 mg three or four times daily.
Children
Purata is not recommended for the treatment of anxiety or insomnia in children.
Treatment of anxiety should not be continued beyond 8-12 weeks including a tapering off period.
Treatment of insomnia should be as short as possible. Generally, the duration of treatment varies from a few days to two weeks with a maximum, including tapering off process of four weeks.
In all cases, the dosage of Purata should be titrated according to the needs of the individual patient and the lowest effective dose necessary to control symptoms should be used for the shortest possible time. The maximum dose should not be exceeded. In certain cases extension beyond the maximum treatment period may be necessary; if so, it should not take place without re-evaluation of the patient's status with special expertise.
Method of administration
For oral administration only.
Myasthenia gravis, hypersensitivity to benzodiazepines, phobic or obsessional states, chronic psychosis, respiratory depression, acute pulmonary insufficiency, sleep apnoea syndrome, severe hepatic insufficiency.
Tolerance
Some loss of efficacy to the hypnotic effects of benzodiazepines may develop after repeated use for a few weeks.
Dependence
Use of benzodiazepines may lead to the development of physical and psychic dependence upon these products. The risk of dependence increases with dose and duration of treatment; it is also greater in patients with a history of alcohol or drug abuse. Therefore, benzodiazepines should be used with extreme caution in patients with a history of alcohol or drug abuse.
Once physical dependence has developed, abrupt discontinuation of benzodiazepines may be associated with physiological and psychological symptoms of withdrawal including extreme anxiety, headache, muscle pain, insomnia, tension, restlessness, confusion and irritability. In severe cases the following symptoms may occur: derealisation, depersonalisation, hyperacusis, numbness and tingling of the extremities, hypersensitivity to light, noise and physical contact, hallucinations or epileptic seizures.
Rebound insomnia and anxiety: a transient syndrome whereby the symptoms that led to treatment with a benzodiazepine recur in enhanced form may occur on withdrawal of treatment. It may be accompanied by other reactions including mood changes, anxiety or sleep disturbances and restlessness. Since the risk of withdrawal phenomena/rebound phenomena is greater after abrupt discontinuation of treatment, it is recommended that dosage be decreased gradually.
Duration of treatment
<) depending on the indication, but should not exceed 4 weeks for insomnia and eight to twelve weeks in case of anxiety, including a tapering off process. Extension beyond these periods should not take place without re-evaluation of the situation.It may be useful to inform the patient when treatment is started it will be of limited duration and explain precisely how the dosage will be progressively decreased. Moreover, it is important that the patient should be aware of the possibility of rebound phenomena, thereby minimising anxiety over such symptoms should they occur while the medicinal product is discontinued.
There are indications that, in the case of benzodiazepines with a short duration of action, withdrawal phenomena can become manifest within the dosage interval, especially when the dosage is high.
When benzodiazepines with a long duration are being used it is important to warn against changing to a benzodiazepine with a short duration of action, as withdrawal symptoms may develop.
Psychiatric and paradoxical reaction
Reactions like restlessness, agitation, irritability, aggressiveness, delusion, rages, nightmares, hallucinations, psychoses, inappropriate behaviour and other adverse behavioural effects are known to occur when using benzodiazepines. Should this occur, use of the medicinal product should be discontinued. They are more likely to occur in children and elderly.
Amnesia
Benzodiazepines may induce anterograde amnesia. The condition occurs most often several hours after ingesting the product and therefore to reduce the risk to patients should ensure that they will be able to have an uninterrupted sleep of 7-8 hours.
Specific patient groups
Benzodiazepines should not be used alone to treat depression or anxiety associated with depression.
Benzodiazepines are not recommended for the primary treatment of psychotic illness or marked personality disorder. Suicide may be precipitated in patients who are depressed and aggressive behaviour toward self and others may be precipitated.
A lower dose is recommended for patients with chronic respiratory insufficiency due to the risk of respiratory depression.
Benzodiazepines are not indicated to treat patients with severe hepatic insufficiency as they may precipitate encephalopathy, renal impairment, muscle weakness or porphyria.
Benzodiazepines should not be given to children without careful assessment of the need to do so; the duration of treatment must be kept to a minimum.
Elderly should be given a reduced dose.
Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
