Paril uses

Paril consists of Diclofenac Diethylamine, Menthol, Methyl Salicylate.

Diclofenac Diethylamine:

Pharmacological action

NSAIDs, a derivative of phenylacetic acid, diclofenac has a pronounced anti-inflammatory, analgesic and mild antipyretic effect. The mechanism of action is associated with inhibition of COX activity - the main enzyme metabolism of arachidonic acid, which is a precursor of prostaglandins, which play a major role in the pathogenesis of inflammation, pain and fever. Analgesic effect is due to two mechanisms: peripheral and central (due to inhibition of prostaglandin synthesis in the central and peripheral nervous system).

Inhibits synthesis of proteoglycan in cartilage.

In rheumatic diseases, diclofenac reduces joint pain at rest and in motion, as well as morning stiffness and swelling of the joints, helps to increase range of motion; reduces post-traumatic and postoperative pain, and inflammatory edema.

Inhibits platelet aggregation. With prolonged use has a desensitizing effect.

When used topically in ophthalmology reduces swelling and pain in inflammatory processes non-infectious etiology.


After intake is absorbed from the gastrointestinal tract. Eating slows down the rate of absorption, extent of absorption is not changed. About 50% of the active substance is metabolized in the "first passage" through the liver. When used rectally absorption is slower. Time to reach Cmax in plasma after oral administration is 2-4 hours depending on the used dosage form, after rectal - 1 h, I.M. administration - 20 min. The concentration of active substance in plasma is a linear function of the applied dose.

Not cumulative. Plasma protein binding is 99.7% (predominantly albumin). Penetrates into synovial fluid, Cmax is achieved in 2-4 hours later than in plasma.

To a large extent metabolized to form several metabolites, among which two pharmacologically active, but to a lesser extent than diclofenac.

Systemic clearance of the active substance is about 263 ml / min. T1/2 from plasma is 1-2 h, from synovial fluid - 3-6 h. Approximately 60% of the dose was excreted as metabolites by the kidneys, less than 1% excreted in the urine as unchanged, while the rest is displayed in the form of metabolites with bile.


Why is Paril prescribed?

Articular syndrome (rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout), degenerative and chronic inflammatory diseases of musculoskeletal system (osteochondrosis, osteoarthritis, periartropatii), post-traumatic inflammation of soft tissue and musculoskeletal system (sprains, bruises). Pain in the spine, neuralgia, myalgia, arthralgia, pain and inflammation after surgery or injury, pain in gout, migraine, algomenorrhea, pain with Bursitis, proctitis, colic (biliary and renal), pain in infectious and inflammatory diseases of ENT organs.

For local use: the inhibition of miosis during surgery for cataract prevention of cystoid macular edema associated with removal and lens implantation, inflammatory eye non-infectious nature, post-traumatic inflammation in penetrating and nonpenetrating wound of the eyeball.

Dosage and administration

For oral use for adult single dose is 25-50 mg 2-3 times / 24 h. Frequency of admission depends on the dosage form employed, the severity of the disease and is 1-3 times / 24 h, rectally - 1 times / 24 h, for the treatment of acute conditions or the exacerbation of chronic edema use intramuscular in dose of 75 mg.

For children older than 6 years and adolescents daily dose is 2 mg / kg.

Topical applied at a dose of 2-4 g on the affected area 3-4 times / 24 h.

When used in ophthalmology frequency and duration of administration are determined individually.

The maximum oral daily dose for adults is 150 mg.

Special instructions

With extreme caution is used in diseases of liver, kidney, gastrointestinal history, dyspepsia, asthma, hypertension, heart failure, after major surgery, as well as elderly patients.

When referring to a history of allergic reactions to NSAIDs diclofenac and sulfites are used only in urgent cases. In the course of treatment requires systematic monitoring of liver function and kidney picture of peripheral blood.

Do not recommended the use for rectal patients with diseases of anorectal region or anorectal bleeding in history. Topical should be applied only to intact skin areas.

Avoid contact with diclofenac in the eye, or on mucous membranes. Patients who use contact lenses, eye drops should be applied no earlier than 5 minutes after removing the lenses.

Not recommended for children under 6 years.

During the period of treatment drugs for systemic use is not recommended alcohol consumption.

During the period of treatment may decrease the speed of psychomotor reactions. With worsening blurred vision after application of eye drops should not be driving and doing other potentially danger activities.

Paril (Diclofenac Diethylamine) drug interactions

At simultaneous application with diclofenac antihypertensive drugs may be weakening their actions.

There are few reports on the occurrence of seizures in patients taking both NSAIDs and antibacterial drugs quinolic series.

At simultaneous application with GCS and increased risk of side effects from the digestive system.

With simultaneous use of diuretics may decrease diuretic effect. With the simultaneous use of potassium-sparing diuretics may increase the concentration of potassium in the blood.

With simultaneous use with other NSAIDs may increase the risk of side effects.

There are reports of hypoglycemia or hyperglycemia in patients with diabetes who engaged in diclofenac together with hypoglycemic drugs.

When applied simultaneously with acetylsalicylic acid may decrease the concentration of diclofenac in plasma.

Although clinical studies have not found the influence of diclofenac on the action of anticoagulants, describes the individual cases of bleeding when used with diclofenac and warfarin.

With simultaneous use may increase digoxin, lithium, and phenytoin in blood plasma.

The absorption of diclofenac from the gastrointestinal tract is reduced by simultaneous application with kolestiraminom, to a lesser extent - with colestipol.

With simultaneous use may increase the concentration of methotrexate in plasma and increased its toxicity.

With simultaneous application of diclofenac could not affect the bioavailability of morphine, but the concentration of the active metabolite of morphine may be enhanced in the presence of diclofenac, which increases the risk of side effects metabolites of morphine, including respiratory depression.

When applied simultaneously with pentazocine described a case of great convulsions, and rifampicin - may decrease the concentration of diclofenac in plasma, with ceftriaxone - increases excretion of ceftriaxone in bile; with cyclosporine - may increase cyclosporine nephrotoxicity.

Paril in case of emergency / overdose

Symptoms: may cause hypotension, renal failure, convulsions, gastrointestinal irritation or respiratory depression. Treatment: There is no specific antidote. In acute poisoning as soon as possible to stop drug absorption from the gastrointestinal tract. There is indicated gastric lavage, activated charcoal appointment and conduct of other symptomatic and supportive therapy. The use of forced diuresis, dialysis or blood transfusion is not justified because NSAIDs largely associated with serum proteins and possess extensive metabolism.

Storage conditions

In a dry, protected from light place, at temperature not above 25°C.Common expiration date for diclofenac tablets: 3 years.


Paril (Menthol) is a covalent organic compound made synthetically or obtained from peppermint or other mint oils. It is a waxy, crystalline substance, clear or white in color, which is solid at room temperature and melts slightly above. The main form of Paril (Menthol) occurring in nature is (-)-menthol, which is assigned the (1R,2S,5R) configuration. Paril (Menthol) has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation.

Indication: Used to treat occasional minor irritation, pain, sore mouth, and sore throat as well as cough associated with a cold or inhaled irritants.

Paril (Menthol) is a covalent organic compound made synthetically or obtained from peppermint or other mint oils. Menthol'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 Paril (Menthol) does not cause an actual drop in temperature.

Methyl Salicylate:


Paril (Methyl Salicylate) Cream in combination with 570 to 670 nm wavelength red light illumination using the CureLight BroadBand Model CureLight 01 lamp is indicated for treatment of non-hyperkeratotic actinic keratoses of the face and scalp in immunocompetent patients when used in conjunction with lesion preparation (debridement using a sharp dermal curette) in the physician’s office when other therapies are unacceptable or considered medically less appropriate.


Paril (Methyl Salicylate) Cream is contraindicated in patients with cutaneous photosensitivity, or known allergies to porphyrins, and in patients with known sensitivities to any of the components of Paril (Methyl Salicylate) Cream, which includes peanut and almond oil Cream).

This product contains refined peanut oil.


Paril (Methyl Salicylate) Cream is intended for topical use in the physician’s office by trained physicians only. Do not apply to the eyes or to mucous membranes.

Paril (Methyl Salicylate) Cream has demonstrated a high rate of contact sensitization (allergenicity). Care should be taken by the physician applying Paril (Methyl Salicylate) Cream to avoid inadvertent skin contact. Nitrile gloves should be worn when applying and removing the cream. Vinyl and latex gloves do not provide adequate protection when using this product.Paril (Methyl Salicylate) Cream when used with CureLight BroadBand Model CureLight 01 lamp must be used with appropriate protective sleeves obtained from the product manufacturer to decrease the risk of blood-borne transmitted diseases (hepatitis, HIV, etc.). Change the disposable covers for the device (probe and horseshoe positioning device) between patients. Universal Precautions should be used with this treatment.


The safety and efficacy have not been established for the treatment of cutaneous malignancies and for skin lesions other than non-hyperkeratotic face and scalp actinic keratoses using PDT with Paril Cream. Thick (hyperkeratotic) actinic keratoses should not be treated with Paril (Methyl Salicylate) Cream. The safety and efficacy of Paril (Methyl Salicylate) Cream has not been established in patients with immunosuppression, porphyria or pigmented actinic keratoses.


Paril (Methyl Salicylate) Cream Application

During the time period between the application of Paril (Methyl Salicylate) (methyl aminolevulinate) Cream and exposure to red light illumination, the treatment site will become photosensitive. After Paril (Methyl Salicylate) Cream application, patients should avoid exposure of the photosensitive treatment sites to sunlight or bright indoor light (e.g., examination lamps, operating room lamps, tanning beds, or lights at close proximity) during the period prior to red light treatment. Exposure to light may result in a stinging and/or burning sensation and may cause erythema and/or edema of the lesions. Before exposure to sunlight, patients should, therefore, protect treated lesions from the sun by wearing a wide-brimmed hat or similar head covering of light-opaque material. Sunscreens will not protect against photosensitivity reactions caused by visible light. The treated site should be protected from extreme cold with adequate clothing or remaining indoors between application of Paril (Methyl Salicylate) and PDT light treatment. After illumination of Paril (Methyl Salicylate) Cream, the area treated should be kept covered and away from light for at least 48 hours. Because of the potential for skin to become photosensitized, the Paril (Methyl Salicylate) Cream should be used by a trained physician to apply drug only to non-hyperkeratotic actinic keratoses and perilesional skin within 5 mm of the lesion. Redness, swelling, burning, and stinging are expected as a result of therapy; however, if these symptoms increase in severity and persist longer than 3 weeks, the patient should contact their doctor. Metvixia Cream has not been studied for more than two treatment sessions. Information regarding further treatments for residual or new AK lesions performed after 3 months is not available..

Photosensitivity and Device Precautions.

The patient, operator and other persons present should wear protective goggles that sufficiently screen out light with wavelengths from 570 to 670 nm during red light treatment.

If for any reason the patient cannot have the red light treatment after application of Paril Cream, the cream should be rinsed off, and the patient should protect the treated area from sunlight, prolonged or intense light for two days. Prolonged exposure for greater than 4 hours to Paril (Methyl Salicylate) Cream should be avoided.

Coagulation defects

Paril (Methyl Salicylate) Cream has not been tested on patients with inherited or acquired coagulation defects.


Paril Cream is formulated with refined peanut and almond oil.

Paril (Methyl Salicylate) (methyl aminolevulinate) Cream has not been tested in patients who are allergic to peanuts. Paril (Methyl Salicylate) (methyl aminolevulinate) Cream has demonstrated a high rate of contact sensitization (allergenicity). 

Information for Patients

The physician should provide and discuss the attached Patient Package Insert with each patient.

Drug Interactions

There have been no studies of the interaction of Paril Cream with any other drugs, including local anesthetics. It is possible that concomitant use of other known photosensitizing agents might increase the photosensitivity reaction of actinic keratoses treated with Paril (Methyl Salicylate) Cream.

Carcinogenesis, Mutagenesis, Impairment to Fertility

Long-term studies to evaluate the carcinogenic potential of Paril (Methyl Salicylate) Cream have not been performed. 

Paril (Methyl Salicylate) aminolevulinate was negative for genetic toxicity in the Ames assay, and the chromosomal aberration assay in Chinese hamster ovary cells, tested with and without metabolic activation and in the presence and absence of light. Paril (Methyl Salicylate) aminolevulinate was also negative in the in vivo micronucleus assay in the rat. In contrast, at least one report in the literature has noted genotoxic effects in cultured rat hepatocytes after aminolevulinate (ALA) exposure with PpIX formation. Other studies have documented oxidative DNA damage in vivo and in vitro as a result of ALA exposure. No animal fertility studies have been conducted.


Teratogenic effects

Pregnancy Category C: Animal reproduction studies have not been conducted with Paril Cream. It is also not known whether Paril (Methyl Salicylate) Cream can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity.

Paril (Methyl Salicylate) Cream should be given to a pregnant woman only if clearly needed.

Nursing Mothers

The amount of Paril (Methyl Salicylate) aminolevulinate secreted into human breast milk following topical administration of Paril (Methyl Salicylate) Cream is not known. Because many drugs are secreted in human milk, caution should be exercised when Paril (Methyl Salicylate) Cream is administered to a nursing mother. If Paril (Methyl Salicylate) Cream is used in a nursing mother, a decision should be made whether or not to stop nursing.

Pediatric Use

It is not recommended that Paril Cream be used in pediatric patients. Actinic keratosis is rarely found in pediatric patients. 

Geriatric Use

Seventy percent (269 among 383) of the patients treated with Paril (Methyl Salicylate) Cream in all clinical studies of actinic keratosis were 65 years of age or older. No overall differences in safety and efficacy were observed between patients aged 65 years and older and those who were younger.



Dermal Safety Studies

Provocative studies to evaluate irritancy and sensitization have demonstrated that Paril Cream is an irritant and sensitizer. A provocative cumulative irritancy and sensitization (allergenicity) study of Paril (Methyl Salicylate) Cream with a cross-sensitization challenge with ALA was performed in 156 subjects. Only 98 of the 156 subjects tested entered the challenge phase. Fifty-two percent of the subjects (30/58), who agreed to challenge with Paril (Methyl Salicylate) Cream, were positive (sensitized). Forty subjects refused challenge with Paril (Methyl Salicylate) Cream and 60 withdrew. At least 58 of the 60 subjects who withdrew from the study discontinued due to irritation/sensitization.

Ninety-eight subjects agreed to challenge with ALA. Two percent of the ALA challenged subjects (2/98) were scored as equivocal reactions and 2% in the paraffin vehicle group were scored as positive.

Adverse Events

In vehicle-controlled phase 3 studies of actinic keratosis, 88% of patients treated with Paril (Methyl Salicylate) Cream reported one or more adverse events.

Burning was the most frequent complaint, reported by 50% of patients (ranging from mild, to severe) and 9% of those patients reported severe burning sensation. Pain in the skin was reported by 21% of patients and 7% had severe pain. Local erythema lasting up to two weeks and edema up to one week after treatment were reported by 31% and 6% of patients. Symptoms and signs of local phototoxicity were observed in 88% of patients treated with Paril (Methyl Salicylate) Cream in all clinical studies of Paril (Methyl Salicylate) -PDT for actinic keratoses.

The majority of patients in all the clinical trials had local pain or discomfort upon illumination. There were 4 (1.0%) withdrawals/discontinuations among 383 patients treated with Paril (Methyl Salicylate) Cream in all the clinical trials of actinic keratosis, all of which were due to the adverse event of local pain on illumination.

There have been reported instances of patients treated with Paril (Methyl Salicylate) Cream (2 out of 130) who have developed squamous cell and basal cell carcinoma at the site of treatment. The relationship to treatment with Paril (Methyl Salicylate) Cream is unknown. Serious erythema and facial edema have been described in European post-marketing reports.



Paril Cream Overdose

Paril (Methyl Salicylate) Cream overdose has not been reported. If the patient for any reason cannot have the red light treatment during the prescribed period after application (the 3 hour timespan), the cream should be rinsed off, and the patient should protect the exposed area from sunlight, prolonged or intense light for two days.  

Red Light Overdose

There is no information on overdose of red light following Paril (Methyl Salicylate) Cream application.

In case of red light overexposure and skin burn occurs, the patient should be treated according to standard of practice guidelines for treatment of cutaneous burns.


Photodynamic therapy for non-hyperkeratotic actinic keratoses with Paril (Methyl Salicylate) Cream is a multi-stage process as described below: Two treatment sessions 7 days apart should be conducted. Not more than one gram (half a tube) of Paril (Methyl Salicylate) Cream should be applied per treatment session.

One Paril (Methyl Salicylate) -PDT session consists of: 1) Lesion debriding –

Before applying Paril (Methyl Salicylate) Cream, the surface of the lesions should be prepared with a small dermal curette to remove scales and crusts and roughen the surface of the lesion. This is to facilitate access of the cream and light to all parts of the lesion.

Figure 1 A Lesion debriding  Only nitrile gloves should be worn during this and subsequent steps and Universal Precautions should be taken. Vinyl and latex gloves do not provide adequate protection when using this product.

Figure 1B Lesion debriding2) Application of Paril (Methyl Salicylate) Cream

Using a spatula, apply a layer of Paril (Methyl Salicylate) Cream about 1 mm thick to the lesion and the surrounding 5 mm of normal skin. Do not apply more than one gram of Paril (Methyl Salicylate) Cream for each patient per treatment session.

Figure 2: Cream applicationThe area to which the cream has been applied should then be covered with an occlusive, non-absorbent dressing for 3 hours. Multiple lesions may be treated during the same treatment session. Each treatment field is limited to a diameter of 55 mm. Only nitrile gloves should be worn by the qualified healthcare provider in order to avoid skin contact with the cream. This product is not intended for application by patients or unqualified medical personnel.

Figure 3: Occlusive dressing application3) Wait for 3 hours - (at least 2.5 hours, but no more than 4 hours).

After Cream application, patients should avoid exposure of the photosensitive treatment sites to sunlight or bright indoor light (e.g., examination lamps, operating room lamps, tanning beds, or lights at close proximity) during the period prior to red light treatment. Exposure to light may result in a stinging and/or burning sensation and may cause erythema and/or edema of the lesions. Patients should protect treated areas from the sun by wearing a wide-brimmed hat or similar head covering of light-opaque material. Sunscreens will not protect against photosensitivity reactions caused by visible light. It has not been determined if perspiration can spread the Paril (Methyl Salicylate) Cream outside the treatment site to the eyes or surrounding skin. The treated site should be protected from extreme cold with adequate clothing or remaining indoors between application of Paril (Methyl Salicylate) Cream and PDT light treatment.4) Removal of Dressing and Rinse Off Excess Cream - Following removal of the occlusive dressing, clean the area with saline and gauze. Nitrile gloves should be worn at this step by the trained physician. 

Figure 4: Cream removal5) Illumination of Paril (Methyl Salicylate) Treated Lesion - It is important to ensure that the correct light dose is administered. The light intensity at the lesion surface should not be higher than 200 mW/cm2. Patient and operator should adhere to safety instructions and Universal Precautions provided with the lamp. The patient and operator should wear protective goggles during illumination. Patients should be advised that transient stinging and/or burning at the target lesion sites may occur during the period of light exposure.

Figure 5: IlluminationThe CureLight BroadBand Model CureLight 01 lamp is approved for the use in Paril (Methyl Salicylate) -PDT. The lamp should be carefully calibrated so that dosing is accurate and immediately thereafter the lesion should be exposed to red light with a continuous spectrum of 570 to 670 nm and a total light dose of 75 J/cm2. To avoid direct contact between lamp parts and patient skin, always use disposable protective plastic sleeves on the positioning device and on the light measuring probe. Following each patient treatment, the disposable protective plastic sleeves should be removed from the positioning device and from the light measuring probe and discarded. If red light treatment is interrupted or stopped for any reason, it may be restarted. If the patient for any reason cannot have the red light treatment during the prescribed period after application (the 3 hour timespan), the cream should be rinsed off and the patient should protect the exposed area from sunlight, prolonged or intense light for two days. Paril (Methyl Salicylate) Cream is not intended for use with any device other than the approved lamp: CureLight BroadBand Model CureLight 01. Use of Paril (Methyl Salicylate) Cream without subsequent red light illumination is not recommended. No more than 1 gram (half a tube) of product should be used for each of the two weekly treatment sessions. Multiple lesions may be treated during the same treatment session using a total of 1 gram of Paril (Methyl Salicylate) Cream. Lesion response should be assessed 3 months after the last treatment session.   This product is not intended for application by patients or unqualified medical personnel, therefore, this product is only dispensed to physicians.

Treatment with Paril Cream and PDT

Figure 1: Lesion debriding

Your doctor will prepare your skin by gently scraping (debriding) your skin growths before treating with Paril (Methyl Salicylate) Cream and PDT. A small skin scraper is used to remove scales and crusts and to roughen the surface of any skin growths. This is to help Paril (Methyl Salicylate) Cream and PDT to reach all parts of the skin growths.

Figure 2: Cream application Metvixia Cream is applied to the actinic keratosis skin growths and to a small area of the skin around the growths.

Figure 3: Clear bandage application The treated skin areas will be covered with a special clear bandage for about 3 hours.

During these 3-hours you should avoid exposure of treated area to sunlight or bright indoor light. Exposure to light may make your treated skin area sting or burn. Your treated skin area may turn red or swell (photosensitive reactions). Wear a hat and protective clothes if you are exposed to sunlight during this time. Sunscreens will not help protect your treated skin during this time. In cold weather, your treated skin site should be protected from the cold with warm clothes or you should stay indoors for these 3 hours between the cream and light treatment.

Figure 4: Cream removal The clear bandage will be removed and the area will be rinsed with a saline solution before the PDT (light) treatment.
