What is Topac Fast Gel?
Topac Fast Gel is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and other symptoms of arthritis of the joints (eg, osteoarthritis), such as inflammation, swelling, stiffness, and joint pain. However, Topac Fast Gel does not cure osteoarthritis and will help you only as long as you continue to use it.
Topac Fast Gel topical 3% gel is also used to treat actinic keratosis, a skin problem that may become cancerous if not treated. The exact way that topical Topac Fast Gel helps this condition is unknown.
Topac Fast Gel topical solution is used to treat pain and swelling caused by osteoarthritis of the knees.
Topac Fast Gel topical patch is used to treat acute pain caused by minor strains, sprains, and contusions (bruises).
Topac Fast Gel is available only with your doctor's prescription.

Topac Fast Gel dosage
General Dosing Instructions
Carefully consider the potential benefits and risks of Topac Fast Gel and other treatment options before deciding to use Topac Fast Gel. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals.
The effectiveness of Topac Fast Gel when taken with food has not been studied in clinical studies. Taking Topac Fast Gel with food may cause a reduction in effectiveness compared to taking Topac Fast Gel on an empty stomach.
Acute Pain
For management of mild to moderate acute pain, the dosage is 18 mg or 35 mg orally three times daily.
Osteoarthritis Pain
For management of osteoarthritis pain, the dosage is 35 mg orally three times daily.
Dosage Adjustments in Patients with Hepatic Impairment
Patients with hepatic disease may require reduced doses of Topac Fast Gel compared to patients with normal hepatic function. As with other Topac Fast Gel products, start treatment at the lowest dose. If efficacy is not achieved with the lowest dose, discontinue use.
Non-Interchangeability with Other Formulations of Topac Fast Gel
Topac Fast Gel capsules are not interchangeable with other formulations of oral Topac Fast Gel even if the milligram strength is the same. Topac Fast Gel capsules contain Topac Fast Gel free acid whereas other Topac Fast Gel products contain a salt of Topac Fast Gel, i.e., Topac Fast Gel potassium or sodium. A 35 mg dose of Topac Fast Gel is approximately equal to 37.6 mg of sodium Topac Fast Gel or 39.5 mg of potassium Topac Fast Gel. Therefore, do not substitute similar dosing strengths of other Topac Fast Gel products without taking this into consideration.
Topac Fast Gel interactions
See also:
What other drugs will affect Topac Fast Gel?
Aspirin: Concomitant administration of Topac Fast Gel and aspirin is not recommended because Topac Fast Gel is displaced from its binding sites during the concomitant administration of aspirin, resulting in lower plasma concentrations, peak plasma levels and AUC values.
Anticoagulants: While studies have not shown Topac Fast Gel to interact with anticoagulants of the warfarin type, caution should be exercised, nonetheless, since interactions have been seen with other NSAIDs. Because prostaglandins play an important role in hemostasis and NSAIDs affect platelet function as well, concurrent therapy with all NSAIDs, including Topac Fast Gel and warfarin, requires close monitoring of patients to be certain that no change in their anticoagulant dosage is required.
Digoxin, Methotrexate, Cyclosporine: Topac Fast Gel, like other NSAIDs, may affect renal prostaglandins and increase the toxicity of certain drugs. Ingestion of Topac Fast Gel may increase serum concentrations of digoxin and methotrexate and increase cyclosporine's nephrotoxicity. Patients who begin taking Topac Fast Gel or who increase their Topac Fast Gel dose or any other NSAID while taking digoxin, methotrexate or cyclosporine may develop toxicity characteristics for these drugs. They should be observed closely, particularly if renal function is impaired. In the case of digoxin, serum levels should be monitored.
Lithium: Topac Fast Gel decreases lithium renal clearance and increases lithium plasma levels. In patients taking Topac Fast Gel and lithium concomitantly, lithium toxicity may develop.
Oral Hypoglycemics:
Topac Fast Gel does not alter glucose metabolism in normal subjects nor does it alter the effects of oral hypoglycemic agents. There are rare reports, however, from marketing experiences, of changes in effects of insulin or oral hypoglycemic agents in the presence of Topac Fast Gel that necessitated changes in the doses of such agents. Both hypo- and hyperglycemic effects have been reported. A direct causal relationship has not been established, but physicians should consider the possibility that Topac Fast Gel may alter a diabetic patient's response to insulin or oral hypoglycemic agents.Diuretics: Topac Fast Gel and other NSAIDs can inhibit the activity of diuretics. Concomitant treatment with potassium-sparing diuretics may be associated with increased serum potassium levels.
Other Drugs: In small groups of patients (7-10/interaction study), the concomitant administration of azathioprine, gold, chloroquine, D-penicillamine, prednisolone, doxycycline or digitoxin did not significantly affect the peak levels and AUC values of Topac Fast Gel. Phenobarbital toxicity has been reported to have occurred in a patient on chronic phenobarbital treatment following the initiation of Topac Fast Gel therapy.
Topac Fast Gel side effects
See also:
What are the possible side effects of Topac Fast Gel?
There have been cases reported of Topac Fast Gel being associated with the development of symptoms resembling the syndrome of inappropriate antidiuretic hormone secretion in elderly women. A patient who had been taking Topac Fast Gel for several years and had increasingly complained of dry, gritty eyes noticed that eye irritation disappeared within 3 days when Topac Fast Gel had to be discontinued because of GI effects.
The most frequent adverse effects reported in patients given Topac Fast Gel are GI in nature. Typical reactions include epigastric pain, nausea, vomiting and diarrhoea. Rarely, peptic ulcer and GI bleeding have occurred. Topac Fast Gel has also been implicated as the causative agent in colonic ulceration, small bowel perforation and pseudomembranous colitis.
Renal papillary necrosis and nephritic syndrome have been reported in patients taking Topac Fast Gel. Elevations of serum aminotransferase activity and clinical hepatitis, including fetal fulminant hepatitis have occurred in patients taking Topac Fast Gel. Self-limiting skin reaction eg, rash or pruritus may occur in patients given Topac Fast Gel.
Aspirin-sensitive asthmatic patients have developed reactions (rhinorrhoea, tightness of chest, wheezing, dyspnoea) when challenged with Topac Fast Gel in doses of 10-25 mg and the CMS in the UK have received a report of 1 aspirin-sensitive patient who died from acute asthma 4 hrs after a single 25-mg dose of Topac Fast Gel.

The use of high dose Topac Fast Gel (150 mg/day) for >4 weeks is contraindicated in patients with established cardiovascular disease (congestive heart failure, established ischemic heart disease, peripheral arterial disease) or uncontrolled hypertension.
Established Cardiovascular Disease or Significant Cardiovascular Risk Factors: The use of high dose Topac Fast Gel (150mg/day) for >4 weeks is contraindicated in patients with established cardiovascular disease (congestive heart failure, established ischemic heart disease, peripheral arterial disease) or uncontrolled hypertension. If Topac Fast Gel treatment is needed, patients with established cardiovascular disease, uncontrolled hypertension or significant cardiovascular risk factors (eg, hypertension, hyperlipidaemia, diabetes mellitus and smoking) should be treated only after careful consideration and at doses ≤100 mg daily if the treatment is for >4 weeks. As the cardiovascular risks of Topac Fast Gel may increase with dose and duration of exposure, Topac Fast Gel should always be prescribed at the lowest effective daily dose and for the shortest duration possible.
Renal Impairment: Topac Fast Gel is contraindicated in patients with renal failure. No specific studies have been carried out in patients with renal impairment, therefore, no specific dose adjustment recommendations can be made. Caution is advised when administering Topac Fast Gel to patients with mild to moderate renal impairment.
Hepatic Impairment: Topac Fast Gel is contraindicated in patients with hepatic failure. No specific studies have been carried out in patients with hepatic impairment, therefore, no specific dose adjustment recommendations can be made.
