Trysin

TRYSIN


COMPOSITION:

Each enteric coated tablet contains:
Trypsin and chymotrypsin  eqvt to 100,000 units of enzymatic activity.

PHARMACOKINETICS
Trysin is released and absorbed in the small intestine when given in enteric coated form passing the destructive activity of the acid pepsin of the stomach.

MECHANISM OF ACTION :

PROTEOLYTIC   ACTION: Trysin causes proteolysis by breaking down proteins into peptones and into smaller fragments called amino acid. The peptones and amino acid are absorbed by the cells of the small intestine.

FIBRINOLYTIC ACTION: Trysin facilitates the action of fibrinolytic agent “plasmin” that restores circulation, resolving edema and hematoma. It promotes phagocytosis to remove the debris.

VASCULAR RESPONSE MODULATOR: The drug increases the levels of APR’s (Acute Phase Reactant), which minimize the necrotic damage and scarring.

MODULATION OF INFLAMMATION: The drug reduces the proinflammatory mediators. The fibrin blocked microcirculation could be cleared earlier by the administration of the enzyme, and hence the inflammation resolves quicker and healing commences at an early stage.

WARNINGS
The tablet must be swallowed, whole to preserve the enteric coating, since damage to enteric coated rapidly causes loss of potency.

ADVERSE EFFECTS:
Generally, it is well tolerated. However, certain effects can be seen like occasional gastric disturbances. An increased intraocular pressure, corneal oedema, striation and uveitis may occur following ophthalmic use.

STORAGE CONDITION
Trysin tablets should be stored in cool dry place.

INDICATION
Trysin is indicated for:

v  Resolving oedema and modulates inflammation associated with various conditions such as accidental and surgical trauma.
v  Assists in episiotomies.
v  Neuralgia with pain radiating into the buttock and lower limb most commonly due to intervertebral disk herniation.
v  Inflammation of a vein associated with thrombous formation, known as thrombophlebitis.
v  Gynaecology:- surgery such as vasectomy and caesarean, Episiotomy, Abdominal Hysterectomy.
v  Bronchitis, for reduction in viscosity of mucus & sputum formation.
v  Dentistry:- specially for tooth extraction, periapical abscess and maxilofacial surgery.
v  Fractures and dislocation
v  Sprains and strains
v  Opthalmology:-Ocular trauma such as macular oedema, black eye, hyphema, uveal tract inflammation, sub-conjunctival hemorrhage, extra ocular trauma.
v  ENT:- Auricular septal hematoma,  nasal fractures, para-pharyngeal abscess.
v  Enhancement of antibiotic concentration at the site of infection and prevention of formation of adhesions.
v  Surgery:- Post-operative wound, Oedema & Haematoma, Prevention of inflammation of the stitch.
      

DOSAGE AND ADMINISTRATION
Trysin is administered 1 tablet 4 times a day. The tablet must be taken half an hour before meal or as directed by the physician.

CONTRAINDICATION
      Trysin should not be employed in patients with severe hepatic insufficiency and should be given cautiously to patient with renal damage or irregularities of blood clotting mechanism. It should not be used for a week after pulmonary haemorrhage.

After many years of wide spread clinical use, there is no reason to believe that proteolytic enzymes is, or may be teratogenic in humans. However it is sound medical principle to exercise precautions in prescribing any medication during the first three months of pregnancy.
 
SPECIAL PRECAUTIONS
Ocular surgery in children less than 20 months, congenital cataract, glaucoma, hepatic or renal diseases, irregularities in blood clotting.

Stimulates tissue healing 


STUDY PROFILE 
Proteolytic enzyme (Trysin) have an excellent safety profile, but there are situation in which they should not be used. For example, the effects of proteolytic enzymes during pregnancy have not been sufficiently evaluated. Although no significant side effect has been noted with any of the proteolytic enzymes, allergic reaction may occur (as with most therapeutic agents).
 Allergies  are triggered by partially undigested protein proteolytic enzymes may reduce allergic symptoms by further breaking down undigested protein to sizes that are too small to cause allergic reactions. Limited scientific evidence supports this theory.proteolytic enzymes such as trypsin and chymotrpsin have anti-inflammatory activity and may even demonstrate antitumor effects.In one preliminary study of a pancreatic cancer patients ,the combination of proteolytic enzymes and other cancer treatments appear to extend survival,despite the fact that most of the patients died. Proteolytic enzymes may also improve immune system function ,for example, in people with shingles (herpes zoster),though this area of research has not been adequately explored.

ONOCOLOGY
The clinical research that currently exists on proteolytic enzymes suggests significant benefits in the treatment of many forms of cancer. Specifically, these studies have shown improvements in the general condition of patient quality of life and modest to significant improvement in life expectancy. The studies have considered of patients with cancer of breast, lung, stomach, head and neck, ovaries, cervix and colon; and lymphomas and multiple myeloma. These studies involved the use of proteolytic enzyme in conjuction with conventional therapy (surgery, chemotherapy, and/or radiation) indicating that proteolytic enzymes can be used safely and effectively with these treatments.
