Antiscar Topical Gel 100 mg+50 IU+10 mg Uses, Dosage, Side Effects, Food Interaction and all others data.
Allantoin is a substance that is endogenous to the human body and also found as a normal component of human diets . In healthy human volunteers, the mean plasma concentration of allantoin is about 2-3 mg/l. During exercise, the plasma allantoin concentration rapidly increases about two fold and remains elevated . In human muscle, urate is oxidized to allantoin during such exercise . The concentration of allantoin in muscles increases from a resting value of about 5000 ug/kg to about 16000 ug/kg immediately after short-term exhaustive cycling exercise .
More specifically, allantoin is a diureide of glyoxylic acid that is produced from uric acid. It is a major metabolic intermediate in most organisms. Allantoin is found in OTC cosmetic products and other commercial products such as oral hygiene products, in shampoos, lipsticks, anti-acne products, sun care products, and clarifying lotions . Allantoin has also demonstrated to ameliorate the wound healing process in some studies .
There is no well controlled and appropriate data that can formally substantiate the pharmacodynamic properties of allantoin . Nevertheless, ongoing studies suggest that allantoin possesses moisturizing and keratolytic effects, as well as abilities to increase the water content of the extracellular matrix and enhance the desquamation of upper layers of dead skin cells, all of which are activities that can promote cell proliferation and facilitate wound healing .
Heparin inhibits reactions that lead to the clotting of blood and the formation of fibrin clots both in vitro and in vivo. Heparin acts at multiple sites in the normal coagulation system. Small amounts of heparin in combination with antithrombin III (heparin cofactor) can inhibit thrombosis by inactivating activated Factor X and inhibiting the conversion of prothrombin to thrombin. Once active thrombosis has developed, larger amounts of heparin can inhibit further coagulation by inactivating thrombin and preventing the conversion of fibrinogen to fibrin. Heparin also prevents the formation of a stable fibrin clot in inhibiting the activation of the fibrin stabilizing factor.
Bleeding time is usually unaffected by heparin. Clotting time is prolonged by full therapeutic doses of heparin; in most cases, it is not measurably affected by low doses of heparin.
Unfractionated heparin is a highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from 3000 to 30,000 daltons. Heparin is obtained from liver, lung, mast cells, and other cells of vertebrates. Heparin is a well-known and commonly used anticoagulant which has antithrombotic properties. Heparin inhibits reactions that lead to the clotting of blood and the formation of fibrin clots both in vitro and in vivo. Small amounts of heparin in combination with antithrombin III, a heparin cofactor,) can inhibit thrombosis by inactivating Factor Xa and thrombin. Once active thrombosis has developed, larger amounts of heparin can inhibit further coagulation by inactivating thrombin and preventing the conversion of fibrinogen to fibrin. Heparin also prevents the formation of a stable fibrin clot by inhibiting the activation of the fibrin stabilizing factor. Heparin prolongs several coagulation tests. Of all the coagulation tests, activated partial prothrombin time (aPTT) is the most clinically important value.

How Antiscar Topical Gel 100 mg+50 IU+10 mg works
There is no well controlled data that can formally substantiate the method of action . However, ongoing studies suggest that there may exist a histological wound healing profile induced by allantoin in rats that leads to the amelioration and fastening of the reestablishment of normal skin . This facilitation of wound healing is supported by observations that wounds inflicted to rat subjects to which topical allantoin preparations were applied histologically demonstrated increased vasodilation, presence of inflammatory exudates, number of inflammatory cells, angiogenesis, fibroblast proliferation, and increased collagen deposition when compared to rat subjects with wounds that did not receive any allantoin administration .
Under normal circumstances, antithrombin III (ATIII) inactivates thrombin (factor IIa) and factor Xa. This process occurs at a slow rate. Administered heparin binds reversibly to ATIII and leads to almost instantaneous inactivation of factors IIa and Xa The heparin-ATIII complex can also inactivate factors IX, XI, XII and plasmin. The mechanism of action of heparin is ATIII-dependent. It acts mainly by accelerating the rate of the neutralization of certain activated coagulation factors by antithrombin, but other mechanisms may also be involved. The antithrombotic effect of heparin is well correlated to the inhibition of factor Xa. Heparin is not a thrombolytic or fibrinolytic. It prevents progression of existing clots by inhibiting further clotting. The lysis of existing clots relies on endogenous thrombolytics.
Dosage
Antiscar Topical Gel 100 mg+50 IU+10 mg dosage
This gel should be applied 3-4 times a day to the affected area and massaged gently in order to achieve better penetration. Continue with a circular motion until the gel is completely absorbed. Treatment may take several weeks or months depending on the size of existing scars and contracture.This gel is very safe and its tolerability has been proven in numerous clinical studies. Small children and even babies can be treated safely.Side Effects
This gel is generally well tolerated even in long-term use. In rare cases, some local irritations are reported such as slight erythema and itching. These side effects do not require discontinuation of the treatment.Toxicity
No studies on repeated dose toxicity and reproductive toxicity have been submitted. Moreover, studies show that the tumor incidence in allantoin treated animals did not differ largely from that found in untreated controls. As a result, further or additional toxicity, mutagenicity, or carcinogenicity tests are not required in view of the endogenous nature of allantoin and the general lack of overall toxicity .
Finally, as allantoin is a normal component of the diet in humans and is a substance of endogenous origin present in the body of humans, it is generally recognized as being a safe substance for humans .
In mouse, the median lethal dose is greater than 5000 mg/kg. Another side effect is heparin-induced thrombocytopenia (HIT syndrome). Platelet counts usually do not fall until between days 5 and 12 of heparin therapy. HIT is caused by an immunological reaction that makes platelets form clots within the blood vessels, thereby using up coagulation factors. It can progress to thrombotic complications such as arterial thrombosis, gangrene, stroke, myocardial infarction and disseminated intravascular coagulation. Symptoms of overdose may show excessive prolongation of aPTT or by bleeding, which may be internal or external, major or minor. Therapeutic doses of heparin give for at least 4 months have been associated with osteoporosis and spontaneous vertebral fractures. Osteoporosis may be reversible once heparin is discontinued. Although a causal relationship has not been established, administration of injections preserved with benzyl alcohol has been associated with toxicity in neonates. Toxicity appears to have resulted from administration of large amounts (i.e., about 100–400 mg/kg daily) of benzyl alcohol in these neonates. Its use is principally associated with the use of bacteriostatic 0.9% sodium chloride intravascular flush or endotracheal tube lavage solutions.
Precaution
During treatment of fresh scars with this preparation, excess cold, UV lights and abrupt massage should be avoided. Avoid contact with eyes, the inside of the nose or mouth and other mucous membranes.Interaction
There is no known and reported drug interaction.Volume of Distribution
40-70 mL/min (approximately the same as blood volume) Although heparin does not distribute into adipose tissues, clinicians should use actual body weight in obese patients to account for extra vasculature.
Elimination Route
In studies on human subjects, a recovery of 19% and 34% of allantoin in the urine was observed but only in two individuals and only after the administration of massive doses of allantoin . After intravenous administration, recovery in the urine was practically quantitative with doses of 75 to 600 mgm in the human model . After 240 mgm, excretion continued for 72 hours in human subjects and the results were similar in regards to subcutaneous injection .
Heparin must be given parenterally as it is not absorbed through the gastrointestinal mucosa. It is usually given by iv infusion or deep sc injection. The onset of action is immediate after iv injection but can be delayed 20 to 60 minutes following sc injection.
Plasma heparin concentrations may be increased and activated partial thromboplastin times (aPTTs) may be more prolonged in geriatric adults (older than 60 years of age) compared with younger adults.
Half Life
When studied in cattle, sheep, and horses, the half-life of allantoin is in the range of 1 to 2.5 hours .
1.5 hours.
The plasma half-life of heparin increases from about 60 minutes with a 100 unit/kg dose to about 150 minutes with a 400 unit/kg dose.
Clearance
Some studies suggest that the average renal clearance of allantoin in normal, healthy human subjects is approximately 123 cc per minute . It is generally agreed upon that exogenously administered allantoin is rapidly excreted .
Adult Clearance = 0.43 ml/kg/min 25-28 weeks gestation = 1.49 ml/kg/min
Elimination Route
Urinary clearance is the predominant excretion route .
The drug appears to be removed mainly by the reticuloendothelial system. A small fraction of unchanged heparin also appears to be excreted in urine. Heparin cannot be eliminated by hemodialysis.
Pregnancy & Breastfeeding use
There are no studies conducted during pregnancy and lactation periods. Therefore it should be used with caution.Contraindication
This gel should not be used in patients with known hypersensitivity to any of its ingredients.Special Warning
Pediatric Use: There are no adequate and well controlled studies on heparin use in pediatric patients. Pediatric dosing recommendations are based on clinical experience. Carefully examine all Heparin Sodium Injection vials to confirm choice of the correct strength prior to administration of the drug. Pediatric patients, including neonates, have died as a result of medication errors in which vials have been confused with “catheter lock flush” vials
Acute Overdose
Symptoms: Bleeding (nose bleeds, blood in urine or tarry stools may be noted as the 1st sign of bleeding).
Management: May give protamine sulfate by slow IV infusion over 10 min to treat severe bleeding (1 mg of protamine sulfate neutralises approx 100 U of heparin). Max: 50 mg as a single dose.
Storage Condition
Store in a cool and dry place, below 25°C. Protect from direct sunlight and moisture. Do not freeze. Keep the medicine out of the reach of children.Innovators Monograph
