Usually the preparation is well tolerated. During a long-term usage of high doses there can be possible follow side effects:
nausea, vomiting, heartburn, diarrhea.
hyperexcitability of CNS, headache.
formation of urinary, cystine and oxalate concernments.
Skin and subcutaneous tissue: allergic reactions.
It can cause erythrocyte hemolysis in patients with insufficiency of glucose-6-phosphatdehydrogenase of hematocytes.
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise take it as soon as you remember and then go back to taking it as you would normally.
Ascozin® increases salicylates (increases a risk of crystalluria), ethynilestradiol,
benzylpenicillin and tetracyclines concentrations in blood, and decreases per oral
contraceptives concentration in blood. It reduces anticoagulation effect of coumarin
derivatives. It improves iron drugs absorption in intestine. It increases general
clearance of ethyl alcohol. Quinolone drugs, calcium chloride, salicylate, corticosteroid
decrease vitamin C reserve when used for a long term. Corticosteroids (cortisone
and prednisolone), which are administered in concrete diseases (arthritis, bronchial
astma etc), also reduce vitamin C and zinc levels.
Concurrent usage of ascorbic acid and deferoxamine enhances tissue toxicity of iron, especially in cardiac muscle that can cause decompensation of blood circulatory system. It can be used only in 2 hours after deferoxamine injection. A long-term administration of high doses in patients, who are treated by disulfiram, inhibits disulfamide-alcohol reaction.
High doses of the preparation decrease efficacy of tricyclic depressants.
nausea, vomiting, intestine spasm, diarrhea; it is possible allergic reaction, kidney dysfunction, blood pressure increase, hyperexcitability of CNS, sleep disturbance.
It is symptomatic.

>RECOMMENDED DOSE AND MODE OF ADMINISTRATION
Depending on area of painfulness 2-4 g of gel (strip is 4 to 8 cm) is applied on skin is rubbed lightly 2-3 times per day. Average daily dose compound 10 g of gel, equivalent to 100 mg of Diclofenac. The drug should not be applied on damaged skin. One should be careful to avoid accidental contact with the eyes and on mucous tunic. It shouldn't apply the gel on open wound.
Generally, the preparation is tolerated well. The small part of drug (about 5 %) is absorbed into the bloodstream when used locally. It more or less eliminates possibility of side effects associated with NSAIDs. Sometimes skin irritation such as, skin rash, oedema, appearance of wheals, papules, scutes, reddening, burning, prickling, skin itch occur at the site of application. If Diclofenac is used on large area for long duration following systemic side effects may appear occur, in cases of concurrent usage of Diclofenac tablets, suppository and/or ampoules. Side effects related to GIT, appearance of generalize rashes, development of reaction of increased sensibility, such as oedema of face (angioedema), apnoea, photosensitivity is rare. In a case of any unusual reactions it is necessary to consult the doctor immediately and stop the further usage of the medicine.
INTERACTIONS WITH OTHER MEDICINAL PRODUCTS
Fanigan Fast Gel can be used along with other medicines, because the components of this drug do not interact systemically with other medicines, including use of Diclofenac sodium by oral route. But in cases of long usage of Fanigan Fast Gel in large dosage it is necessary to know that Diclofenac can increase effect of anticoagulants, GCS, Lithium and it can decrease action of furosemide, thiazide diuretics. It can increase concentration of digoxin in plasma and decrease tolerance of other NSAID, increasing their ulcerogenic action on mucous coat of GIT. The concurrent local usage some medicines, containing NAAA, can irritate the skin locally in the form of urtricaria, reddening, desquamation
Pregnancy and lactation:
It is not allowed to apply gel on big areas of body or to use for a long time in last three months of pregnancy and during lactation period, because data about safety of the drug on foetus and neonates is not available.
Consult the doctor before using the medicine The drug is prescribed carefully for patients with hypersensitivity to local usage of acetylsalicylic acid, different salicylates and other NSAID (bronchial asthma attacks, skin reactions and acute rhinitis). It is necessary to weigh all factors of usefulness and risk. Fanigan is used carefully in patients with ulcer of the stomach or intestines, disorders of the liver and kidney, haematological disorders, relapse of nasal polyposis. It is necessary to wash hands after usage of medicine to avoid the accidental entry of drug in eyes and mucous tunics.
As systemic absorption after topical application of the drug is very low, the likelihood of interactions is insignificant.
In case of large doses of Fanigan® Fast gel, it should be taken into account that Diclofenac may amplify the effect of anticoagulants, corticosteroids, Lithium, and suppress the effect of furosemide and thiazide diuretics.
When concomitant topical application of several drugs containing NSAIDs, local irritation, such as urticaria, redness, desquamation, may develop.
The overdose is not possible as a result of local application of Fanigan Fast Gel.
Hypersensitivity to Diclofenac and other components of this drug; Aspirin induced bronchial asthma; Break in the skin or open wound in area should be avoided; Children below 12 years of age (because there is no data about external usage this medicine in this age group).
Action of each component of Fanigan Fast gel is explained as follows. Diclofenac
inhibits the cyclooxygenase, suppresses synthesis of prostaglandins – endogenous substances, which play a significant role in the genesis of the inflammation, pain, and fever. Diclofenac reduces pain, eliminates inflammation. Menthol
acts on the temperature receptors. It is gives sensation of coolness, constricts capillaries, and decrease of their permeability. It provides local counter-irritation and gentle analgesic actions. Methyl salicylate
is a derivative of salicylic acid, which has local irritation action. Methyl salicylate decreases the pain because of irritation of skin receptors. Methyl salicylate inhibits synthesis of prostaglandins, decreases swelling and infiltration of inflamed tissues. Linseed oil
is alfalinoleic acid, which has anti-inflammatory, antioxidant actions, improves blood circulation at place of application. The action of medicine begins within few minutes after application on skin. During 20-30 min it achieves maximum activity level. It provides relief from the symptoms from day one of beginning of treatment. PHARMACOKINETIC PROPERTIES
When Diclofenac gel is applied topically, Diclofenac is absorbed into the epidermis. In a study in patients with com-promised skin (mainly atopic dermatitis and other dermatitis conditions) of the hands, arms or face, approximately 10% of the applied dose (2 grams of 3% gel over 100 cm2) 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 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 0-t ng.hr/mL (mean±SD) with a Cmax of 4±5 ng/mL and a Tmax of 4.5±8 hours. In comparison, a single oral 75 mg dose of diclofenac produced an AUC of 1600 ng.hr/mL. Therefore, the systemic bioavailability after topical application of Diclofenac gel is lower than after oral dosing. Blood drawn at the end of treatment from 60 patients with AK lesions treated with Diclofenac gel in three adequate and well-controlled clinical trials was assayed for Diclofenac levels. Each patient was administered 0.5 g of Diclofenac gel twice a day for up to 105 days. There were up to three 5 cm X 5 cm treatment sites per patient on the face, forehead, hands, forearm, and scalp. Serum concentrations of Diclofenac were, on average, at or below 20 ng/mL. These data indicate that systemic absorption of Diclofenac in patients treated topically with Diclofenac gel is much lower than that occurring after oral daily dosing of Diclofenac sodium. No information is available on the absorption of Diclofenac when Diclofenac gel is used under occlusion. Distribution:
Diclofenac binds tightly to serum albumin. The volume of distribution of diclofenac following oral administration is approximately 550 mL/kg. Metabolism:
Biotransformation of Diclofenac following oral administration involves conjugation at the carboxyl group of the side chain or single or multiple hydroxylation's resulting in several phenolic metabolites, most of which are converted to glucuronide conjugates. Two of these phenolic metabolites are biologically active, however to a much smaller extent than Diclofenac. Metabolism of Diclofenac following topical administration is thought to be similar to that after oral administration. The small amounts of Diclofenac and its metabolites appearing in the plasma following topical administration makes the quantification of specific metabolites imprecise. Elimination:
Diclofenac and its metabolites are excreted mainly in the urine after oral dosing. Systemic clearance of Diclofenac from plasma is 263±56 mL/min (mean±SD). The terminal plasma half-life is 1-2 hours. Four of the metabolites also have short terminal half-lives of 1-3 hours Systemic exposure (area under the concentration-time curve) and maximum plasma concentrations of Diclofenac are significantly lower with Diclofenac gel than with comparable oral treatment of Diclofenac sodium. Systemic exposure with recommended use of Diclofenac gel (4 x 4 g per day applied to 1 knee) is on average 17 times lower than with oral treatment. (Basis: treatment with Diclofenac gel of 1 knee, 4 times a day versus 50 mg, 3 times a day of oral Diclofenac tablets). The amount of Diclofenac sodium that is systemically absorbed from Diclofenac gel is on average 6% of the systemic exposure from an oral form of Diclofenac sodium. The average peak plasma concentration with recommended use of Diclofenac gel (4 x 4 g per day applied to 1 knee) is 158 times lower than with the oral treatment. The pharmacokinetics of Diclofenac gel has been tested under conditions of moderate heat (application of a heat patch for 15 minutes prior to gel application) and of moderate exercise (first gel application followed by a 20 minutes treadmill exercise). No clinically relevant differences of systemic absorption and of tolerability were found between applications of Diclofenac gel (4 x 4 g per day on 1 knee) with and under the conditions tested. However, the pharmacokinetics of Diclofenac gel was not tested under the condition of heat application following gel application. Therefore, concurrent use of Diclofenac gel and heat is not recommended.
