Dispensation of benzodiazepines is controlled by the Ministry of Health and special prescriptions must be used, with class B prescription notification, using a specific blue document with day validity, each of which can request dispensation ansioliticcos a maximum of five vials of medication for external use injectable or three units for internal use oral route 6.
The noise and vibrations of rotary instruments, brusque movements by dentists themselves, exposure of patients to sharp instruments, reports from friends and relatives of negative experiences, and patients’ level of odontologis about the procedures that are conducted. Tambellini MM, Gorayeb R.
Medications such as benzodiazepines can be used to avoid these complications. Arkin H, Colton RR. These medications’ fn outweigh their disadvantages and as long as none of the steps required for use of benzodiazepines are ignored, they offer a very safe and effective option for use in dental clinical practice.
Use of benzodiazepines in oral and maxillofacial surgery. Oral diazepam versus intravenous midazolam for conscious sedation during cataract surgery performed using topical anesthesia. The principal benzodiazepines used in dentistry are diazepam, midazolam, lorazepam, alprazolam, and triazolam.

Infl uence of anxiety on blood pressure and heart rate during dental treatment. Rozenfeld S, Porto MA. These drugs’ mechanisms of action are exerted on the central nervous system and ultimately result in depression of excitatory cells. Rev Saude Publica ; 31 1: Benzodiazepine use in pregnancy and major malformations or oral cleft: It is therefore possible that this predominant cerebral processing of orofacial sensations may contribute to the aversive anxiety that many patients manifest with respect to dental treatment Plasma concentrations are obtained from 1 to 2 hours after administration and it is completely eliminated from the body after 12 to 15 hours.
Deranged distribution, perverse prescription, unprotected use: Onset of action is from 30 to 45 minutes after administration and its clearance half-life is from 24 to 72 hours, due to production of active metabolites, although the clinical effects disappear from 2 to 3 hours after administration 8. Midazolam is most used in procedures with short duration or in situations in which we intend to induce the patient to sleep; not a first-choice option because of the amnesia effect, although in certain situations this can actually become a beneficial property since the patient will forget the “moment of trauma” and because there is a need for more sophisticated infrastructure, including oximetry control, when compared with diazepam 8, Diazepam is the benzodiazepine most frequently used in dentistry because it is the safest member of this class of drugs for use by clinicians with little experience in conscious sedation techniques.
Eur J Oral Sci. After absorption, diazepam is transported to adipose tissues where it is stored and from where it can return to the bloodstream, causing sedation again Effects vary, depending on the dose administered and the drug used, and can include sedation, hypnosis, muscle relaxation, anticonvulsant effects, coronary dilation, and neuromuscular blockade. Oral benzodiazepines and conscious sedation: Care should also be taken to avoid occurrence of drug interactions, since the pharmacological properties of one or both medications could be increased or reduced.
There is also evidence that patients with high anxiety levels may be prone to greater perception of sensitivity to pain 1. Ethanol has additive effects on benzodiazepines in the CNS and accelerates hepatic metabolism of these drugs.
Penfield W, Rasmussen T. Several different methods have been employed to assess anxiety levels in patients. When activated, the GABA-a receptor increases the frequency with which chloride channels in nerve cells open, increasing entry of chloride ions and provoking a hyperpolarized state in the cell membrane, which, in the final analysis, results in reduced propagation of the excitatory impulse In the absence of GABA, benzodiazepines produce minor or practically null effects on the capacity to transport chloride into the interior of nerve cells 18, Lorazepam Generally used as a premedication, lorazepam also has a long period of latency, which makes use in the dental office problematic.
The characteristics of these reactions include increased conversation initiated by the patient, excitement and excessive movements, and even hostility and rage. Anxiety can complicate dental procedures because of effects such as increased blood pressure, hyperventilation, and fainting. Diazepam Diazepam is the ansiolitifos most frequently used in dentistry because it is the safest member of this class of drugs for use by clinicians with little experience in conscious sedation techniques.

Drug utilization, Self-medication, Health academic staff. Barnes e Nobles; Paradoxical reactions to benzodiazepines: Onset of action occurs around 30 minutes after administration and duration is from 2 to 3 hours Elderly patients may also have abnormalities affecting the routes through which these drugs are absorbed and excreted due to changes in pH, reduced hepatic metabolism, and increased CNS sensitivity to their effects.
The most often administered doses of alprazolam vary from 0. anssioliticos
Benzodiazepines are the medications most used for this technique. What are people afraid of during dental treatment? The anxiolytic effect of midazolam in third molar extraction: These drugs can be metabolized in a range of different tissues and organs, but the primary site of metabolism is the kidneys. Dental surgeons have a range of drugs to choose from for provoking conscious sedation in dental settings using benzodiazepines.
Rev Saude Publica ; 32 1: For pediatric patients, the usual dose varies from 0.
These drugs bind to specific receptor units in the central nervous system CNSpotentiating their effects and resulting in prolonged neuronal hyperpolarization with rapid inhibition or attenuation of transmission of nerve impulses, causing depression of the CNS and producing varying degrees of anxiolytic effects, sedation, anterograde amnesia, relaxation of skeletal musculature, and anticonvulsant activity.
Generally used as a premedication, lorazepam also has a long period of latency, which makes use in the dental office problematic. Midazolam and diazepam compared as sedatives for outpatient surgery under local analgesia.
However we have expected a low and more rationalized utilization.
