FDA prescribing information, side effects and uses. Generic Name: lorazepam. Dosage Form: injection. CIVFor intravenous and intramuscular use. NOT FOR USE IN NEONATESCONTAINS BENZYL ALCOHOL                         WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDSConcomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Monitor patients for respiratory depression and sedation (see WARNINGS and PRECAUTIONS, Drug Interactions). Ativan Description.

Lorazepam, a benzodiazepine with antianxiety, sedative, and anticonvulsant effects, is intended for the intramuscular or intravenous routes of administration. It has the chemical formula: 7- chloro- 5(2- chlorophenyl)- 1,3- dihydro- 3- hydroxy- 2. H- 1, 4- benzodiazepin- 2- one.

The molecular weight is 3. C. A. S. No. is [8. The structural formula is: Lorazepam is a nearly white powder almost insoluble in water. Each m. L of sterile injection contains either 2. L polyethylene glycol 4. Ativan - Clinical Pharmacology. Lorazepam interacts with the γ- aminobutyric acid (GABA)- benzodiazepine receptor complex, which is widespread in the brain of humans as well as other species.

This interaction is presumed to be responsible for lorazepam’s mechanism of action. Lorazepam exhibits relatively high and specific affinity for its recognition site but does not displace GABA. Attachment to the specific binding site enhances the affinity of GABA for its receptor site on the same receptor complex.

The pharmacodynamic consequences of benzodiazepine agonist actions include antianxiety effects, sedation, and reduction of seizure activity. The intensity of action is directly related to the degree of benzodiazepine receptor occupancy. Effects in Pre- Operative Patients. Intravenous or intramuscular administration of the recommended dose of 2 mg to 4 mg of Ativan Injection to adult patients is followed by dose- related effects of sedation (sleepiness or drowsiness), relief of preoperative anxiety, and lack of recall of events related to the day of surgery in the majority of patients. The clinical sedation (sleepiness or drowsiness) thus noted is such that the majority of patients are able to respond to simple instructions whether they give the appearance of being awake or asleep.

The lack of recall is relative rather than absolute, as determined under conditions of careful patient questioning and testing, using props designed to enhance recall. The majority of patients under these reinforced conditions had difficulty recalling perioperative events or recognizing props from before surgery. The lack of recall and recognition was optimum within 2 hours following intramuscular administration and 1.

The intended effects of the recommended adult dose of Ativan Injection usually last 6 to 8 hours. In rare instances, and where patients received greater than the recommended dose, excessive sleepiness and prolonged lack of recall were noted. As with other benzodiazepines, unsteadiness, enhanced sensitivity to CNS- depressant effects of ethyl alcohol and other drugs were noted in isolated and rare cases for greater than 2.

Physiologic Effects in Healthy Adults. Studies in healthy adult volunteers reveal that intravenous lorazepam in doses up to 3. Upper airway obstruction has been observed in rare instances where the patient received greater than the recommended dose and was excessively sleepy and difficult to arouse (see WARNINGS and ADVERSE REACTIONS). Clinically employed doses of Ativan Injection do not greatly affect the circulatory system in the supine position or employing a 7. Doses of 8 mg to 1. Studies in 6 healthy young adults who received lorazepam injection and no other drugs revealed that visual tracking (the ability to keep a moving line centered) was impaired for a mean of 8 hours following administration of 4 mg of intramuscular lorazepam and 4 hours following administration of 2 mg intramuscularly with considerable subject variation. Similar findings were noted with pentobarbital, 1.

Although this study showed that both lorazepam and pentobarbital interfered with eye- hand coordination, the data are insufficient to predict when it would be safe to operate a motor vehicle or engage in a hazardous occupation or sport. Pharmacokinetics and Metabolism. ABSORPTIONIntravenous. A 4- mg dose provides an initial concentration of approximately 7. L. Intramuscular. Following intramuscular administration, lorazepam is completely and rapidly absorbed reaching peak concentrations within 3 hours. A 4- mg dose provides a Cmax of approximately 4.

L. Following administration of 1. IM, the amount of lorazepam delivered to the circulation is proportional to the dose administered. DISTRIBUTION/METABOLISM/ELIMINATIONAt clinically relevant concentrations, lorazepam is 9. L/kg. Unbound lorazepam penetrates the blood/brain barrier freely by passive diffusion, a fact confirmed by CSF sampling. Frequent Fever Causes In Adults.

BOXED WARNINGCorticosteroid therapy, organ transplant, tendinitis, tendinopathy, tendon pain, tendon rupture Systemic quinolones have been associated with disabling and potentially irreversible serious adverse reactions such as tendinopathy, including tendinitis and tendon rupture requiring surgical repair or resulting in prolonged disability.

These reactions can occur within hours to weeks after starting these agents in patients of any age, with or without pre- existing risk factors. Because of this risk for serious and potentially permanent side effects, quinolones should only be used for the treatment of uncomplicated urinary tract infection, acute bacterial exacerbation of chronic bronchitis, or acute bacterial sinusitis in cases where alternative treatment options cannot be used. Discontinue quinolones at the first sign of tendon inflammation or tendon pain as these are symptoms that may precede rupture of the tendon. Avoid quinolone use in patients with a history of tendon disorders or tendon rupture. Tendon rupture typically involves the Achilles tendon; however, ruptures of the hand, shoulder, biceps, thumb, and other tendons have also been reported. Tendinitis and tendon rupture can occur bilaterally.

Rupture can occur during therapy or up to a few months after therapy has been stopped. The risk of tendon rupture is increased in older adults over 6. Other reasons for tendon ruptures include physical activity or exercise, kidney failure, or tendon problems in the past. If patients experience tendon inflammation or pain, they should rest and refrain from exercise until the diagnosis of tendonitis or tendon rupture has been confidently excluded. Cerebrovascular disease, depression, neurotoxicity, peripheral neuropathy, seizure disorder Systemic quinolones have been associated with disabling and potentially irreversible serious neurotoxicity, including central nervous system effects and peripheral neuropathy.

These reactions can occur within hours to weeks after starting these agents in patients of any age, with or without pre- existing risk factors. Because of this risk for serious and potentially permanent side effects, quinolones should only be used for the treatment of uncomplicated urinary tract infection, acute bacterial exacerbation of chronic bronchitis, or acute bacterial sinusitis in cases where alternative treatment options cannot be used. Avoid quinolone use in patients who have previously experienced peripheral neuropathy.

Additionally, use quinolones with caution in patients with a known or suspected CNS disorder (e. Patients with a history of depression or underlying risk factors for depression may be at increased risk for suicidal thoughts or acts. Therapy should be discontinued at the first signs or symptoms of neuropathy (e. Myasthenia gravis Avoid use of systemic quinolones, such as levofloxacin, in patients with a history of myasthenia gravis. Systemic quinolones may exacerbate the signs of myasthenia gravis and lead to life threatening weakness of the respiratory muscles.

Serious postmarketing events, including deaths and the requirement for ventilatory support, have been associated with quinolone use in patients with myasthenia gravis. Because of this risk for serious and potentially permanent side effects, quinolones should only be used for the treatment of uncomplicated urinary tract infection, acute bacterial exacerbation of chronic bronchitis, or acute bacterial sinusitis in cases where alternative treatment options cannot be used. DESCRIPTIONOral, ophthalmic, and IV quinolone antibiotic. Used for bacterial conjunctivitis, sinusitis, chronic bronchitis, pneumonia, skin and skin structure infections, UTIs, prostatitis, inhalation anthrax, and plague. Associated with disabling and potentially irreversible adverse reactions, including tendonitis, tendon rupture, peripheral neuropathy, and central nervous system effects.
