Linseed oil is a rich source of α-Linolenic acid extracted from the dried, ripened seeds of the flax plant Linum usitatissimum. Other fatty acids contained in linseed oil include palmitic acid, stearic acid, oleic acid and linolenic acid. Linseed oil is particularly susceptible to polymerization reactions upon exposure to oxygen in air due to a high content of di- and triunsaturated esters. It is used in drying processes, and is used in other industrial and commercial applications. It is an indirect additive used in food contact substances.
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic ester naturally produced by many species of plants, particularly wintergreens. The compound was first extracted and isolated from plant species Gaultheria procumbens in 1843. It can be manufactured synthetically and it used as a fragrance, in foods, beverages, and liniments. It forms a colorless to yellow or reddish liquid and exhibits a characteristic odor and taste of wintergreen. For acute joint and muscular pain, methyl salicylate is used as a rubefacient and analgesic in deep heating liniments. It is used as a flavoring agent in chewing gums and mints in small concentrations and added as antiseptic in mouthwash solutions.
Methyl salicylate relieve musculoskeletal pain in the muscles, joints, and tendons by causing irritation and reddening of the skin due to dilated capillaries and increased blood flow. It is pharmacologically similar to aspirin and other NSAIDs but as a topical agent it primarily acts as a rubefacient and skin irritant. Counter-irritation is believed to cause a soothing sensation of warmth.

Uses
Indicated for the quick relief from pain, swelling and inflammation due to musculo-skeletal disorders such as sprains, strains, tendinitis, bursitis, hands, neck & shoulder pain, sciatica, muscle stiffness, joint pain, back ache and lumbago.VOLINAC 1% w/w Gel is also used to associated treatment for these conditions: Acute Muscle Pain, Arthritis, Back Pain Lower Back, Backache, Contusions, Joint Pain, Ligament pain, Muscle Inflammation, Muscle Injuries, Muscle Strain, Muscle swelling, Pain, Pain of the Bone and Bones, Pain, Nerve, Partial-Onset Seizures, Postherpetic Neuralgia, Soreness, Muscle, Sprains, Tendon pain, Minor aches, Muscle, joint pains
How VOLINAC 1% w/w Gel works
Counter-irritation is thought to be effective at alleviating musculoskeletal pain as the irritation of the sensory nerve endings is thought to alter or offset pain in the underlying muscle or joints that are served by the same nerves . This is thought to mask the underlying musculoskeletal pain and discomfort. When applied topically, methyl salicylate is thought to penetrate the skin and underlying tissues where it reversibly inhibits cyclooxygenase enzyme and locally and peripherally prevents the production of inflammatory mediators such as prostaglandin and thromboxane A2.
Dosage
VOLINAC 1% w/w Gel dosage
Approximately one-inch band of gel should be applied to the affected site three to four times daily with rubbing till the film disappears. Safety and effectiveness in pediatric patients have not been established.Side Effects
Usually well tolerated. Extremely low frequency of hypersensitivity reactions.Toxicity
Oral LD50 values (mg/kg) for mouse, rat and rabbit are 1110, 887 and 1300, respectively. Oral LD50 values for child and adult human (mg/kg) are 228 and 506, respectively. Although systemic toxicity from topical administration is rare, methyl salicylate can be absorbed in intract skin to cause stimulation of the central nervous system respiratory center, disturbance of lipid and carbohydrate metabolism, and disturbance of intracellular respiration. Severe toxicity can result in acute lung injury, lethargy, coma, seizures, cerebral edema, and death. In case of salicylate poisoning, the treatment consists of general supportive care, gastrointestinal decontamination with activated charcoal in cases of salicylate ingestion, and monitoring of serum salicylate concentrations. Bicarbonate infusions or hemodialysis can be used to achieve enhanced salicylate elimination .
Precaution
For external use only. Avoid contact with the eyes. Stop use and ask a doctor if condition worsens or does not improve within 7 days. Keep out of the reach of children. If swallowed, get medical help or contact a poison control center right away.Interaction
Diclofenac Sodium may have the following drug interactions:Lithium and digoxin: Diclofenac may increase plasma concentrations of lithium and digoxin.Anticoagulants: There are isolated reports of an increased risk of haemorrhage with the combined use of diclofenac and anticoagulant therapy, although clinical investigations do not appear to indicate any influence on anticoagulant effect.Antidiabetic agents: Clinical studies have shown that diclofenac can be given together with oral antidiabetic agents without influencing their clinical effect.Cyclosporin: Cases of nephrotoxicity have been reported in patients receiving cyclosporin and diclofenac concomitantly.Methotrexate: Cases of serious toxicity have been reported when methotrexate and NSAIDs are given within 24 hours of each other.Quinolone antimicrobials: Convulsions may occur due to an interaction between quinolones and NSAIDs. Therefore, caution should be exercised when considering concomitant therapy of NSAID and quinolones.Other NSAIDs and steroids: Co-administration of diclofenac with other systemic NSAIDs and steroids may increase the frequency of unwanted effects. With aspirin, the plasma levels of each is lowered, although no clinical significance is known.Volume of Distribution
After absorption, methyl salicylate is distributed throughout most body tissues and most transcellular fluids, primarily by pH dependent passive processes. Salicylate is actively transported by a low-capacity, saturable system out of the CSF across the choroid plexus. The drug readily crosses the placental barrier.
Elimination Route
Approximately 12-20% of topically applied methyl salicylate may be systemically absorbed through intact skin within 10 hours of application, and absorption varies with different conditions such as surface area and pH. Dermal bioavailability is in the range of 11.8 – 30.7%. For the assessment of potential oral exposure to salicylates, bioavailability is assumed to be 100% .
Half Life
The plasma half-life for salicylate is 2 to 3 hr in low doses and about 12 hr at usual anti-inflammatory doses. The half-life of salicylate may be as long as 15 to 30 hr at high therapeutic doses or when there is intoxication.
Elimination Route
Excreted by kidneys as free salicylic acid (10%), salicyluric acid (75%), salicylic phenolic (10%) and acyl glucuronide (5%), and gentisic acid (less than 1%).
Pregnancy & Breastfeeding use
The safety of this gel has not been established during pregnancy. There are no well-controlled studies of diclofenac in pregnant women.Contraindication
Known hypersensitivity to any part of the preparation.Storage Condition
