Actions of Diclofenac sodium (Delete GEL) in details
Diclofenac sodium extended-release tablets have analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of diclofenac sodium extended-release tablets, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Diclofenac is a potent inhibitor of prostaglandin synthesis in vitro. Diclofenac concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because diclofenac is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.
How should I take Diclofenac sodium (Delete GEL)?
Take Diclofenac sodium (Delete GEL) exactly as directed on the label, or as prescribed by your doctor. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger amounts or for longer than recommended. Use the lowest dose that is effective in treating your condition.
For treatment of pain or primary dysmenorrhea the recommended dosage of Diclofenac sodium (Delete GEL) is 50 mg three times daily. In some patients an initial dose of 100 mg of Diclofenac sodium (Delete GEL), followed by 50 mg doses, may provide better relief.
For the relief of osteoarthritis the recommended dosage of Diclofenac sodium (Delete GEL) is 100-150 mg/day in divided doses, i.e. 50 mg two or three times a day.
For the relief of rheumatoid arthritis the recommended dosage is 150-200 mg/day in divided doses, i.e. 50 mg three or four times a day.
Different formulations of diclofenac, Voltaren (diclofenac sodium tablets) and Diclofenac sodium (Delete GEL) (diclofenac potassium immediate-release tablets) are not necessarily equivalent in strength even if the milligram strength is the same.
If you use Diclofenac sodium (Delete GEL) long-term, you may need frequent medical tests.
Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Diclofenac sodium (Delete GEL) administration
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
If you switch brands of diclofenac, your dose needs may change. Follow your doctor's instructions about how much medicine to take.
Do not crush, chew, or break an extended-release tablet. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.
Dissolve the diclofenac powder (Diclofenac sodium (Delete GEL)) with 1 to 2 ounces of water. Do not use any other type of liquid. Stir this mixture and drink all of it right away. Diclofenac powder works best if you take it on an empty stomach.
Call your doctor if your headache does not completely go away after taking Diclofenac sodium (Delete GEL). Do not take a second dose of diclofenac powder without your doctor's advice.
Do not crush, chew, or break an enteric-coated pill. Swallow the pill whole. The enteric-coated pill has a special coating to protect your stomach. Breaking the pill could damage this coating.
If you use this medication long-term, your liver function will need to be checked with frequent blood tests. Visit your doctor regularly.
Store at room temperature away from moisture and heat.
Diclofenac sodium (Delete GEL) pharmacology
Pharmacodynamics
Diclofenac sodium is one of a series of phenylacetic acids that has demonstrated anti-inflammatory and analgesic properties in pharmacological studies. It is thought to inhibit the enzyme cyclooxygenase, which is essential in the biosynthesis of prostaglandins.
Animal Studies
Prostaglandins have been shown in many animal models to be mediators of certain kinds of intraocular inflammation. In studies performed in animal eyes, prostaglandins have been shown to produce disruption of the blood-aqueous humor barrier, vasodilation, increased vascular permeability, leukocytosis, and increased intraocular pressure.
Pharmacokinetics
Results from a bioavailability study established that plasma levels of diclofenac following ocular instillation of two drops of Diclofenac sodium ophthalmic solution, 0.1% to each eye were below the limit of quantification (10 ng/mL) over a 4-hour period. This study suggests that limited, if any, systemic absorption occurs with Diclofenac sodium ophthalmic solution, 0.1%.
Clinical Trials
Postoperative Anti-Inflammatory Effects
In two double-masked, controlled, efficacy studies of postoperative inflammation, a total of 206 cataract patients were treated with Diclofenac sodium ophthalmic solution, 0.1% and 103 patients were treated with vehicle placebo. Diclofenac sodium ophthalmic solution, 0.1% was favored over vehicle placebo over a 2-week period for the clinical assessments of inflammation as measured by anterior chamber cells and flare.
In double-masked, controlled studies of corneal refractive surgery (radial keratotomy (RK) and laser photorefractive keratectomy (PRK)) patients were treated with Diclofenac sodium ophthalmic solution, 0.1% and/or vehicle placebo. The efficacy of Diclofenac sodium ophthalmic solution, 0.1% given before and shortly after surgery was favored over vehicle placebo during the 6-hour period following surgery for the clinical assessments of pain and photophobia. Patients were permitted to use a hydrogel soft contact lens with Diclofenac sodium ophthalmic solution, 0.1% for up to three days after PRK.
Actions of Linseed oil (Delete GEL) in details
Not known.
Actions of Menthol (Delete GEL) in details
Menthol (Delete GEL) primarily activates the cold-sensitive TRPM8 receptors in the skin. Menthol (Delete GEL), after topical application, causes a feeling of coolness due to stimulation of 'cold' receptors by inhibiting Ca++ currents of neuronal membranes. It may also yield analgesic properties via kappa-opioid receptor agonism.
Menthol (Delete GEL) pharmacology
Menthol (Delete GEL) is a covalent organic compound made synthetically or obtained from peppermint or other mint oils. Menthol (Delete GEL)'s ability to chemically trigger cold-sensitive receptors in the skin is responsible for the well known cooling sensation that it provokes when inhalated, eaten, or applied to the skin. It should be noted that Menthol (Delete GEL) does not cause an actual drop in temperature.
Actions of Methyl salicylate (Delete GEL) in details
Methyl salicylate (Delete GEL) is a topically applied pain-relieving cream that is greaseless, nonstaining and pleasant-smelling. Applied on the skin, it produces a warm sensation which penetrates deep down, providing lasting relief from pain, skin irritation or stiffness. Methyl salicylate (Delete GEL) is hypoallergenic and soothing.
