Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Screening Demographics: All volunteers selected for this study will be healthy men or women 18 years of age or older at the time of dosing. The weight range will not exceed ± 15% for height and body frame as per Desirable Weights for Men -1983 Metropolitan Height and Weight Table or as per Desirable Weights for Women -1983 Metropolitan Height and Weight Table
• Screening Procedures: Each volunteer will complete the screening process within 28 days prior to Period I dosing. Consent documents for both the screening evaluation and HIV antibody determination will be reviewed, discussed, and signed by each potential participant before full implementation of screening procedures.
• Screening will include general observations, physical examination, demographics, medical and medication history, an electrocardiogram, sitting blood pressure and heart rate, respiratory rate and temperature. -The physical examination will include, but may not be limited to, an evaluation of the cardiovascular, gastrointestinal, respiratory and central nervous systems.
• The screening clinical laboratory procedures will include:
• HEMATOLOGY: hematocrit, hemoglobin, WBC count with differential; RBC count, platelet count
• CLINICAL CHEMISTRY: serum creatinine, BUN, glucose, AST(GOT), ALT(GPT), albumin, total bilirubin, total protein, and alkaline phosphatase;
• HIV antibody and hepatitis B surface antigen screens;
• URINALYSIS: by dipstick, microscopic examination if dipstick positive; and .
• URINE DRUG SCREEN: ethyl alcohol, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates and phencyclidine.
• SERUM PREGNANCY SCREEN (female volunteers only)
• If female and:
• of childbearing potential, is practicing an acceptable barrier method of birth control for the duration of the study as judged by the investigator(s), such as condoms, sponge, foams, jellies, diaphragm; intrauterine device (IUD), or abstinence
• is postmenopausal for at least I year; or
• is surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy).

You may not qualify if:

• Volunteers with a recent history of drug or alcohol addiction or abuse.
• Volunteers with the presence of a clinically significant disorder involving the cardiovascular, respiratory, renal, gastrointestinal, immunologic, hematologic, endocrine, or neurologic system(s) or psychiatric disease (as determined by the medical investigator).
• Volunteers whose clinical laboratory test values are outside the accepted reference range and when confirmed on re-examination are deemed to be clinically significant.
• Volunteers demonstrating a positive hepatitis B surface antigen screen or a reactive HIV antibody screen.
• Volunteers demonstrating a positive drug abuse screen when screened for this study.
• Female volunteers demonstrating a positive pregnancy screen.
• Female volunteers who are currently breastfeeding.
• Volunteers with a history of allergic response(s) to gabapentin or related drugs.
• Volunteers with a history of clinically significant allergies including drug allergies.
• Volunteers with a clinically significant illness during the 4 weeks prior to Period I dosing (as determined by the medical investigator).
• Volunteers who currently use tobacco products.
• Volunteers who have taken any drug known to induce or inhibit hepatic• drug metabolism in the 30 days prior to Period I dosing.
• Volunteers who report donating greater than 150 mL of blood within 30 days prior to Period I dosing. All subjects will be advised not to donate blood for four weeks after completing the study.
• Volunteers who have donated plasma (e.g. plasmapheresis) within 14 days prior to Period I dosing. All subjects will be advised not to donate plasma for four weeks after completing the study.
• Volunteers who report receiving any investigational drug within 30 days prior to Period I dosing.
