This summary outlines the pharmacological agents used to treat various forms of substance dependence, their side effects, and key implications for dental practice, as detailed in your document.
Treatment for Alcohol Dependence
-
Withdrawal Symptoms: The acute symptoms of alcohol withdrawal are typically managed with CNS depressants like benzodiazepines.
-
Long-Term Treatment:
-
Acamprosate: The document notes no dental-related adverse effects for acamprosate.
-
Naltrexone: This drug interacts with opioids, and its adverse effects are typically transient.
-
Disulfiram: This drug can cause drowsiness and headache. It has a significant interaction with metronidazole, which should be avoided.
-
Treatment for Nicotine Dependence
-
Bupropion: This medication can cause dry mouth, dizziness, agitation, anxiety, tremor, and headache.
-
Nicotine Replacement Therapy (NRT): Adverse effects of NRT vary by delivery method and can include dizziness, headache, a burning-lip sensation (from mouth spray), hiccups, cough (from inhalation), and vivid dreams (from the 24-hour patch).
-
Varenicline: Side effects of varenicline include headache, taste disturbance, abnormal dreams, and sleep disorders.
Treatment for Opioid Dependence
-
Buprenorphine: The document notes that adverse effects of buprenorphine are not dental-related, but it interacts with opioids and ketoconazole.
-
Methadone: A key dental consideration for methadone is its potential to cause QT prolongation, which can affect the use of other medications. Patients on methadone maintenance therapy often present with high rates of caries and periodontal disease.
-
Naltrexone: This is also used for opioid dependence.
Dental Implications of Illicit Substance Abuse
The document also provides important information on the oral health effects of the substances themselves, which is distinct from the side effects of the treatment medications.
-
Cannabis: Associated with poor oral and periodontal health. An acute dose combined with a local anesthetic containing adrenaline may prolong tachycardia. Chronic use is linked to oral leucoplakia, oral cancer, and oral candidiasis.
-
Methamphetamine: Associated with poor oral hygiene, rampant caries (“meth mouth”), bruxism, and xerostomia. Local anesthetics with vasoconstrictors should be avoided when the patient is intoxicated.
-
Cocaine: Associated with bruxism, clenching, and gingival erosions or ulceration.
-
Opioids: Associated with rampant caries, periodontitis, and anxiety. Injectable use carries risks of blood-borne viruses and infective endocarditis.
General Dental Management
-
“Doctor Shoppers”: Clinicians should be vigilant for patients seeking specific analgesics or anxiolytics and can refuse to prescribe if a request seems inappropriate.
-
Pain Management: For patients in recovery from opioid dependence (e.g., on methadone), opioid analgesics should be avoided to prevent relapse; non-opioid analgesics are preferred.
-
Coordinated Care: It is important to coordinate with the patient’s other healthcare providers for safe and effective management.
