Indikazzjonijiet terapewtiċi:

Midazolam injection is indicated: - intramuscularly or intravenously for preoperative sedation/anxiolysis/amnesia; - intravenously as an agent for sedation/anxiolysis/amnesia prior to or during diagnostic, therapeutic or endoscopic procedures, such as bronchoscopy, gastroscopy, cystoscopy, coronary angiography, cardiac catheterization, oncology procedures, radiologic procedures, suture of lacerations and other procedures either alone or in combination with other CNS depressants; - intravenously for induction of general anesthesia, before administration of other anesthetic agents. With the use of narcotic premedication, induction of anesthesia can be attained within a relatively narrow dose range and in a short period of time. Intravenous midazolam can also be used as a component of intravenous supplementation of nitrous oxide and oxygen (balanced anesthesia); - continuous intravenous infusion for sedation of intubated and mechanically ventilated patients as a component of anesthesia or during treatment in a critical care setting. Injectable midazolam is contraindicated in patients with a known hypersensitivity to the drug. Benzodiazepines are contraindicated in patients with acute narrow-angle glaucoma. Benzodiazepines may be used in patients with open-angle glaucoma only if they are receiving appropriate therapy. Measurements of intraocular pressure in patients without eye disease show a moderate lowering following induction with midazolam; patients with glaucoma have not been studied. Midazolam Injection contains midazolam a Schedule IV control substance. Midazolam was actively self-administered in primate models used to assess the positive reinforcing effects of psychoactive drugs. Midazolam produced physical dependence of a mild to moderate intensity in cynomolgus monkeys after 5 to 10 weeks of administration. Available data concerning the drug abuse and dependence potential of midazolam suggest that its abuse potential is at least equivalent to that of diazepam. Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (convulsions, hallucinations, tremor, abdominal and muscle cramps, vomiting and sweating), have occurred following abrupt discontinuation of benzodiazepines, including midazolam. Abdominal distention, nausea, vomiting, and tachycardia are prominent symptoms of withdrawal in infants. The more severe withdrawal symptoms have usually been limited to those patients who had received excessive doses over an extended period of time. Generally milder withdrawal symptoms (e.g., dysphoria and insomnia) have been reported following abrupt discontinuance of benzodiazepines taken continuously at therapeutic levels for several months. Consequently, after extended therapy, abrupt discontinuation should generally be avoided and a gradual dosage tapering schedule followed. There is no consensus in the medical literature regarding tapering schedules; therefore, practitioners are advised to individualize therapy to meet patient's needs. In some case reports, patients who have had severe withdrawal reactions due to abrupt discontinuation of high-dose long-term midazolam, have been successfully weaned off of midazolam over a period of several days.

WARNINGS
Personnel and Equipment for Monitoring and Resuscitation
ADULTS AND PEDIATRICS:Intravenous midazolam has been associated with
respiratory depression and respiratory arrest, especially when used
for sedation in
noncritical care settings. In some cases, where this was not
recognized promptly
and treated effectively, death or hypoxic encephalopathy has resulted.
Intravenous
midazolam should be used only in hospital or ambulatory care settings,
including
physicians' and dental offices, that provide for continuous monitoring
of
respiratory and cardiac function, e.g, pulse oximetry. Immediate
availability of
resuscitative drugs and age- and size-appropriate equipment for
bag/valve/mask
ventilation and intubation, and personnel trained in their use and
skilled in airway
management should be assured (see WARNINGS). For deeply sedated
pediatric
patients, a dedicated individual, other than the practitioner
performing the
procedure, should monitor the patient throughout the procedure.
Risks From Concomitant Use With Opioids
Concomitant use of benzodiazepines and opioids may result in profound
sedation,
respiratory depression, coma, and death. Monitor patients for
respiratory
depression and sedation (see WARNINGSand PRECAUTIONS: DRUG
INTERACTIONS).
Individualization of Dosage
Midazolam must never be used without individualization of dosage. The
initial
intravenous dose for sedation in adult patients may be as little as 1
mg, but should
not exceed 2.5 mg in a normal healthy adult. Lower doses are necessary
for older
(over 60 years) or debilitated patients and in patients receiving
concomitant
narcotics or other central nervous system (CNS) depressants. The
initial dose and
all subsequent doses should always be titrated slowly; administer over
at least 2
minutes and allow an additional 2 or more minutes to fully evaluate
the sedative
effect. The use of the
