Brief summary
This study is conducted to determine whether the test product (GW483100 10 mg containing montelukast sodium equivalent to 10 mg of montelukast) is bioequivalent to the reference montelukast sodium 10 mg tablets (innovator product) in healthy adult volunteers under fasting conditions. This is an open-label, balanced, randomized, single dose, two-way crossover study, enrolling 32 healthy human subjects to ensure at least 28 subjects complete the study. Each subject enrolled will participate in two treatment periods separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. Total duration in the study for each subject will be approximately 7 weeks from screening to the subject's last visit.
Interventions
Test Montelukast (GW483100) is available as round, biconvex, pink 10 mg film-coated tablet (containing montelukast sodium equivalent to 10 mg of montelukast) and is administered as a single dose with 240 mL of water.
Reference Montelukast (innovator product) is available as pale beige, rounded square shaped,10 mg film-coated tablet (containing montelukast sodium equivalent to 10 mg of montelukast) and is administered as a single dose with 240 mL of water. Singular is the innovator product used for this study, which is a trade name owned by Merck Sharp and Dohme Corporation.

Eligibility
Inclusion criteria
* Between 18 and 65 years of age inclusive, at the time of signing the informed consent. * Healthy, non smoker, as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. * A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or
Exclusion criteria
, outside the reference range for the population being studied may be included only if the investigator in consultation with the Medical Monitor if required agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. * Body weight \>=50 kilograms (kg) and body mass index (BMI) within the range 19 - 24.9 kg/square meter (m\^2) (inclusive) * Healthy male or female subjects: MALES: Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until 24 hours after the last dose of study medication. a.) Vasectomy with documentation of azoospermia. b.) Male condom plus partner use of one of the contraceptive following options: contraceptive subdermal implant; intrauterine device or intrauterine system; oral contraceptive, either combined or progestogen alone; injectable progestogen; contraceptive vaginal ring; and percutaneous contraceptive patches. FEMALES: Eligible to participate, if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin \[hCG\] test), not lactating, and at least one of the following conditions applies: a.) Non-reproductive potential defined as: Pre-menopausal females with one of the following: documented tubal ligation, documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, hysterectomy, Documented Bilateral Oophorectomy Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone \[FSH\] and estradiol levels consistent with menopause). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. b.) Reproductive potential and agrees to follow one of the options listed in the Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) from 30 days prior to the first dose of study medication and until 24 hours after the last dose of study medication and completion of the follow-up visit. * Capable of giving signed informed consent as described in protocol which includes compliance with the requirements and restrictions listed in the consent form and in the protocol.
