Pharmacokinetics
Absorption and distribution in the body. The amount of diclofenac that is absorbed systemically from a Voltaren patch within 24 hours is similar to that when using an equivalent amount of Voltaren Emulgel (1% external gel). 99.7% of diclofenac binds to serum proteins, mainly albumin (99.4%). Elimination. The total systemic clearance of diclofenac from plasma is (263 ± 56) ml / min. The final T1 / 2 in the blood plasma is 1-2 hours. Four metabolites, including two active, also have a short T1 / 2 - 1-3 hours. One metabolite - 3'-hydroxy-4'-methoxydiclofenac - has a longer half-life, however, is inactive. Diclofenac and its metabolites are excreted mainly in the urine. In patients with impaired renal function, the accumulation of diclofenac and its metabolites does not occur. In patients with chronic hepatitis or non-compensated cirrhosis, the kinetics and metabolism of diclofenac follow the same pattern as in patients without liver disease. Preclinical studies have shown the safety of the use of the drug.

Use during pregnancy and lactation
The use of the drug in pregnant women has not been studied, so the Voltaren transdermal patch should not be used during pregnancy, especially in the third trimester due to the possibility of lowering the tone of the uterus and / or premature closure of the arterial duct of the fetus. Studies on animals did not reveal any direct or indirect negative effects on pregnancy, childbirth, fetal and postembryonic development. There is no data on the penetration of the drug into breast milk, therefore the Voltaren transdermal patch is not recommended be used during breastfeeding.

Tablets should be swallowed whole with a liquid, preferably before meals. For adults, the recommended initial dose is 100-150 mg / day. In relatively mild cases of the disease, as well as for long-term therapy, 75-100 mg / day is sufficient. The daily dose should be divided into several doses. To relieve night pain or morning stiffness, in addition to taking the drug during the day, diclofenac is prescribed in the form of rectal suppositories at bedtime; at the same time, the total daily dose should not exceed 150 mg. In case of primary dysmenorrhea, the daily dose is selected individually; usually it is 50-150 mg. The initial dose should be 50-100 mg; if necessary, for several menstrual cycles, it can be increased to 150 mg / day.The drug should be started when the first symptoms appear. Depending on the dynamics of clinical symptoms, treatment can be continued for several days. For children 1 year old and older, the drug is prescribed at a dose of 0.5–2 mg / kg body weight / day (in 2–3 doses, depending on the severity of the disease) . For the treatment of rheumatoid arthritis, the daily dose may be maximized to 3 mg / kg (in several doses). The maximum daily dose is 150 mg.
