Amyl nitrite vitrellae 0.2ml

Although inhalant abuse is common, it is one of the most neglected and overlooked forms of substance abuse. Inhalants refer to a wide variety of substances including volatile solvents, aerosols, gases, and nitrites. The mechanism of action of inhalants has not been fully defined. Several molecular targets contribute to the pharmacology, including ion-channel proteins that control neuronal excitability. These agents interact with various receptors and can cause changes in cell-membrane fluidity and nerve-membrane ion channels. Three main pharmacologic categories of inhalants, namely, volatile solvents and anesthetic gases, nitrous oxide, and volatile alkyl nitrites, have distinct pharmacologies, mechanisms of action, and toxicities. Inhalants are linked to multisystem damage affecting the pulmonary, cardiac, dermatologic, renal, hematologic, gastrointestinal, hepatic, and neurologic systems. Chronic inhalant abuse can also cause psychiatric, cognitive, behavioral, and anatomical deficits in humans, leading to reduced productivity and quality of life. Inhalant abuse during pregnancy is associated with fetal abnormalities. Clinical assessment for inhalant abuse should be done systematically. After decontamination and stabilization of the patient, further history and physical examination is necessary to establish an appropriate diagnosis based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Laboratory testing for inhalant abuse is very limited, and imaging studies may be helpful in certain situations. The treatment of inhalant use disorder is similar to that of other substance abuse disorders and includes supportive care, pharmacotherapy, and behavioral therapy. Preventive measures are essential.
