Bioequivalence Study of Neurogabin-M (Gabapentin 400 mg) Capsule With Parketin (Gabapentin 400 mg) Capsules (BE)

Bioequivalence Study of Gabapentin 400 mg Capsule

This is a single-dose, two-periods, two-sequence, two-way crossover, single oral dose bioequivalence study.

Study Overview

• Status: Completed
• Conditions: Healthy Volunteers; Bioequivalence Study
• Intervention / Treatment: Drug: Neurogabin (Gabapentin) 400 mg capsule; Drug: Parketin (Gabapentin) 400 mg capsule

Detailed Description

This is an Open Label, Randomized, Single Dose, Two Way Cross over, Two Period, Two Treatment, Two Sequence Bioequivalence Study to compare the rate and extent of absorption of test drug Neurogabin-M 400 mg, Capsule with reference drug Parketin 400 mg Capsules in healthy adult subjects, under fasting conditions.

The study will be comprised of two Periods, I and II, each consisting of 47 hours, 11 hours before and 36 hours after the drug administration. All subjects will be divided into two groups of 12 subjects in each group. One group will be treated with the test drug (T) and the other one with reference drug (R) in Period I. After the wash-out period of 7 days, the same will receive the alternate treatment (RT) in Period II.

Blood samples at 0 hr (before drug administration) ,1.0, 1.5 , 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 8.0, 10.0, 12.0, 14.0, 24.0, 28.0, & 36.0 hrs will be taken in both periods for quantification of drug in plasma.

All subjects will be monitored clinically for health status throughout during the periods of study and vital signs will be measured at time of check in and 1, 2, 4, 6, 8, 11, 24 and 36th hours after drug administration. ECG will be measured at time of screening in the best interest of subject safety and well being.

• Participant capable of understanding the informed consent.
• Non Smokers, who have not smoked in last 3 months.
• Medical history, physical examination and screening tests must fall in normal range, unless the investigator considers the abnormality to be clinically not significant.
• Clinically normal physical findings including ECG and safety laboratory values at the Screening visit and on Day -1 of each treatment period, including negative results for drugs of abuse, breath alcohol, Hepatitis B, Hepatitis C and HIV.
• Participants (who can read and understand Urdu) should be able to give informed consent, understand and sign the Informed Consent Form.
• Participants should have adequate organ function (i.e., kidney, liver and heart).
• All subjects will have urine samples assayed for the presence of drugs of abuse as part of the clinical screening procedures and at each study period check-in.

Exclusion Criteria:

• Any active allergic disease or a history of any significant allergic disease (e.g. Rhinitis, dermatitis, asthma).
• Known hypersensitivity to Investigational drug(s).
• Abnormal results of blood and urine tests conducted at screening unless the investigator considers an abnormality to be clinically irrelevant.
