PHARMACOKINETICS
Absorption
When diclofenac sodium gel is applied topically, diclofenac is
absorbed into the epidermis. In a study
in patients with compromised skin (mainly atopic dermatitis and other
dermatitic conditions) of the hands,
arms or face, approximately 10% of the applied dose (2 grams of 3% gel
over 100 cm ) of diclofenac
was absorbed systemically in both normal and compromised epidermis
after seven days, with four times
daily applications.
After topical application of 2 g diclofenac sodium gel three times
daily for six days to the calf of the
leg in healthy subjects, diclofenac could be detected in plasma. Mean
bioavailability parameters were
AUC
9±19 ng/hr/mL (mean±SD) with a C
of 4±5 ng/mL and a T
of 4.5±8 hours. In comparison,
