Diclofenac is available as an ointment for topical application, primarily used to treat pain and inflammation associated with conditions like osteoarthritis and other musculoskeletal injuries [1].
What kind of pain does diclofenac ointment treat?
Diclofenac ointments are indicated for the symptomatic relief of mild to moderate pain and inflammation. This includes pain from osteoarthritis of superficial joints, such as knees and hands, and soft tissue injuries like sprains, strains, and bruises [2].
How does diclofenac ointment work?
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). When applied topically as an ointment, it works by inhibiting cyclooxygenase (COX) enzymes, which are responsible for the production of prostaglandins. Prostaglandins are substances that contribute to inflammation, pain, and fever. By reducing prostaglandin synthesis at the site of application, diclofenac helps alleviate pain and reduce swelling [3].
How do I use diclofenac ointment?
Dosage and application frequency vary depending on the specific product and the condition being treated. Generally, a small amount of the ointment is applied to the affected area and gently rubbed in. It is important to follow the instructions on the product packaging or as directed by a healthcare professional. Avoid applying to broken skin or mucous membranes [2].
What are the side effects of diclofenac ointment?
Common side effects may include local skin reactions at the application site, such as redness, itching, or a burning sensation. Systemic absorption is generally low, but rare side effects associated with oral NSAIDs, such as gastrointestinal issues or allergic reactions, are possible, especially with prolonged or widespread use [4].
When does the patent for diclofenac expire?
Diclofenac is a well-established drug, and its original patents have long since expired, allowing for the production of generic versions [5]. Information on specific formulations or newer delivery systems might be available through resources like DrugPatentWatch.com [1].
Are there alternatives to diclofenac ointment?
