As a side effect of medicines or recreational drugs, hypoventilation may become potentially life-threatening.Many different central nervous system (CNS) depressant drugs such as ethanol, benzodiazepines, barbiturates, GHB, sedatives, and opioids produce respiratory depression when taken in large or excessive doses, or mixed with other depressants.
Coadministration of benzodiazepine drugs at therapeutic doses with erythromycin may cause serious psychotic symptoms, especially in persons with other, significant physical complications. [ 63 ] Oral contraceptive pills reduce the clearance of nitrazepam, which may lead to increased plasma levels of nitrazepam and accumulation. [ 64 ]
Lung symptoms in a patient who is taking a medicinal drug that can cause pulmonary toxicity should not automatically lead to a diagnosis of "pulmonary toxicity due to the medicinal drug", because some patients can have another (i.e., simultaneous) lung disease, e.g. an infection of the lungs not related to the medicinal drugs the patient is ...
Benzodiazepine overdose (BZD OD) describes the ingestion of one of the drugs in the benzodiazepine class in quantities greater than are recommended or generally practiced. The most common symptoms of overdose include central nervous system (CNS) depression, impaired balance, ataxia , and slurred speech.
The symptoms of an opiate toxidrome include the classic triad of coma, pinpoint pupils and respiratory depression [3] as well as altered mental states, shock, pulmonary edema and unresponsiveness. Complications include bradycardia, hypotension and hypothermia. Substances that may cause this toxidrome are opioids.
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. Although ARDS can present with pulmonary edema (fluid accumulation), it is a distinct clinical syndrome that is not synonymous with pulmonary edema.
In contrast, most benzodiazepine overdose does not benefit from its antidote, flumazenil. [11] Respiratory therapy/respiratory physiotherapy may be beneficial in some cases of respiratory failure. [12] [13] Type 1 respiratory failure may require oxygen therapy to achieve adequate oxygen saturation. [14]
Benzodiazepines may also cause or worsen depression. [20] Infusions or repeated intravenous injections of diazepam when managing seizures, for example, may lead to drug toxicity, including respiratory depression, sedation, and hypotension. Drug tolerance may also develop to infusions of diazepam if it is given for longer than 24 hours. [20]
