This study tests whether galantamine (GAL) reduces HIV-related inflammation and cognitive deficits. In this double-blind placebo-controlled crossover study, HIV-infected individuals (N=120; 60 smokers and 60 non-smokers) will be randomized to 12 weeks of GAL or placebo, followed by a 4-week washout, then 12 weeks of GAL or placebo (arms switched). Outcomes are monocyte/macrophage and T cell activation and neurocognitive performance.

Smokers (HIV+S) will report at least 5 instances of smoking per day, on average for the past year and provide a breath carbon monoxide (CO) sample greater than 5 ppm at Intake and at the beginning of each treatment period 2. Non-smokers (HIV+NS) will report smoking fewer than 100 cigarettes in their lifetime, or less than 5 pack years of smoking and no cigarettes in the last year. They will self-report no current use of any tobacco or nicotine product and will provide a CO sample of less than 3 ppm at Intake and at the beginning of each treatment period. If CO sample does not reflect self-report, the PI will be consulted to determine eligibility. Exclusion Criteria: Subjects who present with and/or self-report the following criteria will not be eligible to participate in the study. Smoking Behavior 1. Current enrollment or plans to enroll in another smoking cessation program in the next 7 months. 2. Regular (daily) use of electronic cigarettes, chewing tobacco, snuff, snus, cigars, cigarillos, or pipes. 3. Current use or plans to use nicotine substitutes (gum, patch, lozenge, e-cigarette) or smoking cessation treatments in the next 7 months. Alcohol/Drug Use 1. Current untreated and unstable diagnosis of substance abuse or dependence (if past use and if receiving treatment and stable for at least 30 days, eligible) 2. Positive urine drug screen for cocaine, methamphetamines, phencyclidine (PCP), barbiturates, ecstasy (MDMA), at Intake or Lab visits. Those who screen positive for amphetamines, benzodiazepines, methadone, oxycodone, and/or opiates (low level cut-off 300 ng/mL) and who are prescribed these medications will be reviewed on a case-by-case basis by the study physician and PIs (see Measures and Table 1 for details). Participants believed to have a false-positive result on the drug screen may continue in the study, with investigator approval. Medical/Psychiatric Conditions 1. Women who are pregnant, planning a pregnancy or lactating 2. Current diagnosis of unstable and untreated major depression (if stable for at least 30 days, eligible) 3. Current or past diagnosis of psychotic disorder 4. Cancer diagnosis within the past 6 months (except basal cell carcinoma) 5. Major heart disease or stroke within the past 6 months 6. Uncontrolled hypertension (systolic blood pressure greater than 160 or diastolic blood pressure greater than 100). 7. Medical conditions contraindicated for use with galantamine: 1. Diagnosis of Alzheimer's disease or dementia 2. Epilepsy or other seizure disorder 8. Bladder outflow obstruction 9. Active HCV co-infection (if cured, requires study physician approval) 10. Liver function tests more than 20% outside of the normal range; Gamma-glutamyl transpeptidase (GGT) values more than 20% outside of the normal range. If Albumin/Globulin ratios are 20% outside of normal range the abnormal value will be evaluated for clinical significance by the Study Physician and eligibility will determined on a case-by-case basis. 11. Renal disease or renal dysfunction (e.g., serum creatinine levels greater than 1.5 X upper limit of normal). Those with moderate hepatic impairment or creatinine clearance 9 to 59 mL/min shall not exceed the 16 mg/day dose. 12. Peptic ulcer disease (requires study physician approval) 13. Suicide risk as indicated by at least one of the following on the Columbia Suicide Severity Rating Scale (the PI and/or study psychologist will be consulted to assess safety and determine eligibility in cases close to the eligibility cutoffs): 1. Current suicidal ideation (within 30 days of enrollment) 2. Two or more lifetime suicide attempts or episodes of suicidal behavior 3. Any suicide attempt or suicidal behavior within 2 years of enrollment Medication 1. Current use or discontinuation within the last 14 days of: 1. Quit smoking medications including varenicline (Chantix), bupropion (Wellbutrin) 2. Anti-psychotic medications (e.g., Zyprexa, Clozaril, Seroquel, Risperdal). If used to treat psychotic symptoms. Other uses may be eligible pending physician approval). 3. Systemic Steroids (e.g., Prednisone). 4. Alzheimer's disease medications (e.g., Acetylcholinesterase inhibitors (ACIs), Aricept/donepezil, Exelon/rivastigmine, Tacrine, or memantine) 5. Irritable bowel syndrome medication (e.g., Dicyclomine/Bentyl) 6. Heart medications (e.g., quinidine). 7. Muscle relaxants (e.g., Anectine/succinylcholine) 8. Anti-seizure medications (e.g. Ativan, Banzel, Carbatrol, Dilantin, Lamictal, Gabitril, Lyrica, Neurontin, Tegretol, Topomax) if used to treat a seizure disorder or epilepsy. Other uses may be eligible. 9. Urinary retention medications (e.g., Duvoid/bethanechol, Proscar/finasteride, Avodart/dutasteride, Dibenzyline/ phenoxybenzamine, Regitine/phentolamine) 2. Daily use of: 1. Opiate-containing medications for chronic pain (Duragesic/fentanyl patches, Percocet, Oxycontin). Smokers who report taking opiate-containing medications on an "as-needed" basis will be instructed to refrain from use until their study participation is over and that they will be tested to ensure they have complied with this requirement. 2. Chronic obstructive pulmonary disease (COPD) medication (e.g., Atrovent/Ipratropium Bromide) 3. Known allergy to study medication. Subjects will be instructed to refrain from using any study prohibited drugs/medications (both recreational and prescription) throughout their participation in the study. |

| Primary | Change in Cognition | Cognitive function will be assessed 8 times throughout study participation at Lab Visits and Mid-treatment Visits. Participants will complete measures of executive function, verbal learning and memory and response inhibition. The primary outcome is the change from baseline cognitive function after 12 weeks of treatment. Because this is a within-subject crossover study, change in cognition will be measured during each treatment arm. | Period1 Lab 1 (Week 0), Period 1 Lab 2 (Week 12), Period 2 Lab 1 (Week 16), Period 2 Lab 2 (Week 28) | |
| Primary | Change in Inflammation | Cellular markers of immune activation will be measured in whole blood and soluble markers of immune activation will be measured in plasma at Lab Visits. The primary outcome is the change in monocyte and T cell surface activation and soluble markers after 12 weeks of treatment. Because this is a within-subject crossover study, changes in cellular markers will be measured during each treatment arm. | Period1 Lab 1 (Week 0), Period 1 Lab 2 (Week 12), Period 2 Lab 1 (Week 16), Period 2 Lab 2 (Week 28) | |
| Secondary | Monocyte Transcriptomics | Monocytes will be isolated from blood samples and analyzed for differences in monocyte expression between smoking and non-smoking groups and between treatment arms. Gene expression patterns will also be correlated with soluble and cell surface markers of inflammation. | Period1 Lab 1 (Week 0), Period 1 Lab 2 (Week 12), Period 2 Lab 1 (Week 16), Period 2 Lab 2 (Week 28) |
