Structovial injection is used to treat knee pain caused by osteoarthritis (OA) in patients who have already been treated with pain relievers (e.g., acetaminophen) and other treatments that did not work well.
Structovial is similar to a substance that occurs naturally in the joints. It works by acting like a lubricant and shock absorber in the joints and helps the joints to work properly.
Structovial is to be administered only by or under the immediate supervision of your doctor.
Structovial indications
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Structovial is used to treat knee pain caused by osteoarthritis (a disorder of joints that causes stiffness, pain and loss of movement due to breakdown of lubricating fluid between joints) when treatment with common painkillers or other physical therapy (exercise, physiotherapy etc.) does not provide adequate relief. It is also used for treatment of mouth sores, prevention of skin aging and during cataract surgery.
Structovial description
Each bottle contains 100 mL soln plus 1 applicator for nasal use and 1 applicator for the use in the ear, sealed in a bag.
Inside the metal bottle, the soln remains isolated and not in contact with the propellant because it is contained within a bag made of nontoxic material. The propellant used is air and it is pressurized within the entire space surrounding the bag inside the metal bottle. The inhalation of Structovial occurs via valve positioned above the bag.
With the system: The air is used like a gas propellant, so Structovial does not damage the ozone layer. It is necessary to use preservatives so the possibility of allergic reaction is reduced. The bottle can be used in any direction so Structovial is practical and easy to use.

Directions For Use
Structovial® is administered by intra-articular injection. A treatment cycle consists of five injections given at weekly intervals. Some patients may experience benefit with three injections given at weekly intervals. This has been noted in studies reported in the literature in which patients treated with three injections were followed for 60 days.

Precaution: Strict aseptic administration technique must be followed.
Warning: Do not concomitantly use disinfectants containing quaternary ammonium salts for skin preparation because Structovial can precipitate in their presence.
Inject subcutaneous lidocaine or similar local anesthetic prior to injection of Structovial®.
Precaution: Remove joint effusion, if present, before injection of Structovial®.
Do not use the same syringe for removing joint effusion and for injecting Structovial®.
Take care to remove the tip cap of the syringe and needle aseptically.
Inject Structovial® into the joint through a 20-gauge needle.
Precaution: The vial/syringe is intended for single use. The contents of the vial must be used immediately once the container has been opened. Discard any unused Structovial®. Inject the full 2 mL in one knee only. If treatment is bilateral, a separate vial should be used for each knee.

To date, there are no reports of incompatibilities (interactions) of Structovial with other solutions for intra-articular administration. The patient may benefit from the concurrent use of oral analgesic and anti-inflammatory agents during the first days of treatment.
Incompatibiliies: There is a known incompatibility between sodium hyaluronate and quaternary ammonium salts eg, benzalkonium chloride which can be used as skin disinfectants. Structovial must therefore never come into contact with such products, nor with medical or surgical equipment treated with these types of products, since Structovial can precipitate in their presence.
Structovial® was investigated in a pivotal clinical investigation conducted in the United States in which there were three arms (164 subjects treated with Structovial®; 168 with placebo; and 163 with naproxen) (refer to Table 1). Common adverse events reported for the Structovial®-treated subjects were gastrointestinal complaints, injection site pain, knee swelling/effusion, local skin reactions (rash, ecchymosis), pruritus, and headache. Swelling and effusion, local skin reactions (ecchymosis and rash), and headache occurred at equal frequency in the Structovial®- and placebo-treated groups. Structovial® treated subjects had 48/164 (29%) incidents of gastrointestinal complaints that were not statistically different from the placebo-treated group. A statistically significant difference in the occurrence of pain at the injection site was noted in the Structovial®-treated subjects: 38/164 (23%) in comparison to 22/168 (13%) in the placebo-treated subjects (p = 0.022). There were 6/164 (4%) premature discontinuations in Structovial®-treated subjects due to injection site pain in comparison to 1/168 ( < 1%) in the placebo-treated subjects. These differences were not statistically significant. Two (2/164, 1.2%) Structovial®-treated subjects and 3/168 (1.8%) placebo-treated subjects were reported to have positive bacterial cultures of effusion aspirated from the treated knee. The two Structovial®-treated subjects and two of the placebo-treated subjects did not exhibit evidence of infection clinically or subsequently and were not treated with antibiotics. One of the placebo-treated subjects was hospitalized and received presumptive treatment for septic arthritis.
Structovial® has been in clinical use in Europe since 1987. Analysis of the adverse events that have been reported with the use of Structovial® in Europe reveals that most of the events are related to local symptoms such as pain, swelling/effusion, and warmth or redness at the injection site. Usually such symptoms disappear within a few days by resting the affected joint and applying ice locally. Only sporadically have these events been more severe and longer lasting. Very rare cases of intra-articular infection have been reported. Strict aseptic technique must be followed in administering Structovial®. Systemic allergic reactions rarely have been recorded. Isolated cases of an anaphylactic or anaphylactic-like reaction have been reported in post-marketing experience and they all resolved. Allergic-type signs and symptoms such as rash, pruritus, and urticaria also are very rare. A few cases of fever were reported. In some instances, they were associated with local reactions, in other cases, no association other than temporal was found with the use of the product.
Adverse experience data from the literature contain no evidence of increased risk relating to retreatment with Structovial®. The frequency and severity of adverse events occurring during repeat treatment cycles did not increase over that reported for a single treatment cycle. (Carrabba et al., 1995; Carrabba et al., 1991; Kotz and Kolarz, 1999; Scali, 1995).
Structovial gel is contraindicated for use in breast augmentation, or for implantation into bone, tendon, ligament, or muscle,
Structovial gel is contraindicated for patients with a history of known hypersensitivity to avian proteins.
Structovial gel must not be injected into blood vessels. Introduction of Structovial gel into the vasculature may occlude the vessels and could cause infarction or embolization.
