In another randomized,
crossover study, 20 mg Levitra was administered at 8:00 a.m. after an
overnight fast or immediately after consuming a high-fat breakfast (57
per cent fat), or at 6:00 p.m. on an empty stomach or after consuming a
moderate-fat meal (30 per cent fat).
Results showed that Levitra PK [effectiveness] parameters were largely
unaffected by food, except when taken with a meal with high-fat content
(more than 55 per cent). In this situation, absorption was delayed by
one hour.
