This is a bioequivalence study, which is a regulatory requirement to ensure comparable in vivo performance, i.e. similarities in terms of safety and efficacy, after administration of two different dosage forms of escitalopram.

All subjects will receive three separate dosages of 20 mg escitalopram, which are 2 x 10 mg of the conventional dosage form (Treatment A) and 2 x 10 mg of the new dosage form being tested (Treatment B) and 1 x 20 mg of the new dosage form being tested (Treatment C). Test treatments B and C will each be compared to Treatment A, which is the active comparator (reference formulation).

Inclusion Criteria:

• Body mass index (BMI) between 19 kg/m2 and 29 kg/m2, inclusive
• The subject is, in the opinion of the investigator, generally healthy based on assessment of medical history, physical examination, vital signs, electrocardiogram (ECG), and the results of the haematology, clinical chemistry, urinalysis, serology, and other laboratory tests

Exclusion Criteria:

• The subject has taken disallowed medication within 1 week prior to the first dose of investigational medicinal product (IMP), or within 5 half-lives prior to inclusion for any medication ingested, whichever is longer
• The subject has a significant history of drug or alcohol abuse

• The subject has any concurrent illness that may affect the particular target or metabolism of the IMP
