What are the side effects of alprazolam or lorazepam? Pretty much the same. Most are from nervous system depression, which causes cognitive dysfunction, depression, dizziness, drowsiness, dysarthria a motor speech disorder , fatigue, irritability, memory impairment, and sedation.
How fast do they work and how long do they last? There are some subtle differences between the two here. This is important if you are using them before getting on a plane, having a root canal, or getting into an MRI scanner. With alprazolam Xanax the onset of action for BOTH the immediate release and extended release formulations is 1 hour.
Regular alprazolam will work for about 5 hours; extended release about 11 hours. Lorazepam has a more rapid onset of action, 30 — 60 minutes, and may last up to 8 hours. Both are cleared by the liver, so they will last longer in folks with liver disease. Xanax and Ativan tablets are both scored, so pill splitting is an option. Xanax comes in 0. The clinical significance of this is unknown.
However, use of lorazepam for prolonged periods and in geriatric patients requires caution, and there should be frequent monitoring for symptoms of upper G. Safety and effectiveness of Ativan lorazepam in children of less than 12 years have not been established. As with other benzodiazepines, periodic blood counts and liver function tests are recommended for patients on long-term therapy. Carcinogenesis And Mutagenesis No evidence of carcinogenic potential emerged in rats during an month study with Ativan lorazepam.
No studies regarding mutagenesis have been performed. Pregnancy Reproductive studies in animals were performed in mice, rats, and two strains of rabbits. Occasional anomalies reduction of tarsals, tibia , metatarsals , malrotated limbs, gastroschisis , malformed skull, and microphthalmia were seen in drug-treated rabbits without relationship to dosage. Although all of these anomalies were not present in the concurrent control group, they have been reported to occur randomly in historical controls.
The clinical significance of the above findings is not known. However, an increased risk of congenital malformations associated with the use of minor tranquilizers chlordiazepoxide, diazepam, and meprobamate during the first trimester of pregnancy has been suggested in several studies. Because the use of these drugs is rarely a matter of urgency, the use of lorazepam during this period should be avoided. The possibility that a woman of childbearing potential may be pregnant at the time of institution of therapy should be considered.
Patients should be advised that if they become pregnant, they should communicate with their physician about the desirability of discontinuing the drug. In humans, blood levels obtained from umbilical cord blood indicate placental transfer of lorazepam and lorazepam glucuronide. Infants of mothers who ingested benzodiazepines for several weeks or more preceding delivery have been reported to have withdrawal symptoms during the postnatal period.
Symptoms such as hypoactivity, hypotonia , hypothermia , respiratory depression, apnea , feeding problems, and impaired metabolic response to cold stress have been reported in neonates born of mothers who have received benzodiazepines during the late phase of pregnancy or at delivery.
Nursing Mothers Lorazepam has been detected in human breast milk; therefore, it should not be administered to breastfeeding women, unless the expected benefit to the woman outweighs the potential risk to the infant.
Sedation and inability to suckle have occurred in neonates of lactating mothers taking benzodiazepines. Infants of lactating mothers should be observed for pharmacological effects including sedation and irritability.
Clinical circumstances, some of which may be more common in the elderly, such as hepatic or renal impairment, should be considered. Therefore, in the management of overdosage, it should be borne in mind that multiple agents may have been taken. Symptoms Overdosage of benzodiazepines is usually manifested by varying degrees of central nervous system depression ranging from drowsiness to coma.
In mild cases, symptoms include drowsiness, mental confusion, paradoxical reactions, dysarthria and lethargy. In more serious cases, and especially when other drugs or alcohol were ingested, symptoms may include ataxia , hypotonia , hypotension , cardiovascular depression, respiratory depression, hypnotic state, coma, and death.
Management General supportive and symptomatic measures are recommended; vital signs must be monitored and the patient closely observed. When there is a risk of aspiration , induction of emesis is not recommended. Gastric lavage may be indicated if performed soon after ingestion or in symptomatic patients. Administration of activated charcoal may also limit drug absorption. Hypotension, though unlikely, usually may be controlled with norepinephrine bitartrate injection. Lorazepam is poorly dialyzable.
Lorazepam glucuronide, the inactive metabolite, may be highly dialyzable. The benzodiazepine antagonist flumazenil may be used in hospitalized patients as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose.
The complete flumazenil package insert including Contraindications, Warnings, and Precautions should be consulted prior to use. Ativan lorazepam is readily absorbed with an absolute bioavailability of 90 percent. Peak concentrations in plasma occur approximately 2 hours following administration.
The mean half-life of unconjugated lorazepam in human plasma is about 12 hours and for its major metabolite, lorazepam glucuronide, about 18 hours. Ativan lorazepam is rapidly conjugated at its 3-hydroxy group into lorazepam glucuronide which is then excreted in the urine. Lorazepam glucuronide has no demonstrable CNS activity in animals. The plasma levels of lorazepam are proportional to the dose given.
There is no evidence of accumulation of lorazepam on administration up to six months. Studies comparing young and elderly subjects have shown that advancing age does not have a significant effect on the pharmacokinetics of lorazepam.
Carcinogenesis And Mutagenesis No evidence of carcinogenic potential emerged in rats during an month study with Ativan lorazepam. Dosage for patients with severe hepatic insufficiency should be adjusted carefully according to patient response; lower doses may be sufficient generic viagra caps such patients. Long term use of both alprazolam and lorazepam carries the same risk of the development of physical and psychological dependence and withdrawal symptoms what discontinuing them. Most are from nervous system depression, which causes cognitive dysfunction, depression, dizziness, drowsiness, dysarthria a motor speech disorderlorazepam, irritability, memory impairment, and sedation. As with like benzodiazepines, periodic blood counts and liver function tests are recommended for patients on long-term therapy. The dosage of Ativan lorazepam should be increased gradually when needed to help avoid adverse effects. The generic 2mg is quite look.
