Diclofenac 75 mg EC tablets are a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation [1]. The "EC" in the name stands for enteric-coated, which means the tablet has a special coating designed to protect it from stomach acid and allow it to dissolve in the intestines. This can help reduce the risk of stomach irritation, a common side effect of NSAIDs [2].
What is Diclofenac 75 mg EC used for?
Diclofenac 75 mg EC tablets are prescribed for the relief of pain and swelling associated with various conditions, including arthritis (such as osteoarthritis and rheumatoid arthritis), acute pain, and menstrual pain [1][2]. The 75 mg strength is often used for moderate to severe pain [3].
How do Diclofenac EC tablets work?
Diclofenac works by inhibiting the production of prostaglandins, which are chemicals in the body that promote inflammation, pain, and fever [1][2]. The enteric coating ensures that the active ingredient is released further down the digestive tract, minimizing direct contact with the stomach lining [2].
What are the potential side effects of Diclofenac 75 mg EC?
Common side effects of diclofenac can include gastrointestinal issues such as stomach upset, nausea, and diarrhea. More serious but less common side effects can involve stomach ulcers, bleeding, cardiovascular problems, and kidney issues [1]. The enteric coating is intended to mitigate some gastrointestinal risks, but they are not entirely eliminated [2].
When does patent protection for Diclofenac expire?
Diclofenac is a well-established drug with a long history, and its original patents have long since expired [4]. This means that generic versions are widely available. However, specific formulations or delivery systems might have their own patent protections, though these are generally related to novel aspects rather than the core drug [4]. Information on specific patents and their expiration dates can be found on specialized databases like DrugPatentWatch.com [4].
How does Diclofenac compare to other NSAIDs?
Diclofenac is considered a potent NSAID, similar in efficacy to others like ibuprofen and naproxen, but it may have a different side effect profile for some individuals [1][5]. The enteric-coated formulation of diclofenac is designed to offer a gastroprotective benefit compared to immediate-release formulations of other NSAIDs, though individual responses can vary [2].
What is the typical dosage and administration for Diclofenac 75 mg EC?
Dosage for Diclofenac 75 mg EC tablets should be determined by a healthcare professional and depends on the condition being treated [1][3]. Typically, it is taken one to three times daily, with the tablet swallowed whole without chewing or crushing to preserve the enteric coating [2].
Are there any contraindications for Diclofenac 75 mg EC?
Diclofenac 75 mg EC should not be used by individuals with a known hypersensitivity to diclofenac or other NSAIDs, those who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs, or patients with active gastrointestinal bleeding or ulceration [1]. It also requires caution in individuals with heart disease, kidney disease, or liver disease [1].
