DRUGS & SUPPLEMENTS
Levoptin usesLevoptin consists of Chloramphenicol, Naphazoline Hydrochloride, Prednisolone Sodium Phosphate.
An antibiotic first isolated from cultures of Streptomyces venequelae in 1947 but now produced synthetically. It has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. It acts by interfering with bacterial protein synthesis and is mainly bacteriostatic. (From Martindale, The Extra Pharmacopoeia, 29th ed, p106)
Indication: Used in treatment of cholera, as it destroys the vibrios and decreases the diarrhea. It is effective against tetracycline-resistant vibrios. It is also used in eye drops or ointment to treat bacterial conjunctivitis.
Levoptin (Chloramphenicol) is a broad-spectrum antibiotic that was derived from the bacterium Streptomyces venezuelae and is now produced synthetically. Levoptin (Chloramphenicol) is effective against a wide variety of microorganisms, but due to serious side-effects (e.g., damage to the bone marrow, including aplastic anemia) in humans, it is usually reserved for the treatment of serious and life-threatening infections (e.g., typhoid fever). Levoptin (Chloramphenicol) is bacteriostatic but may be bactericidal in high concentrations or when used against highly susceptible organisms. Levoptin (Chloramphenicol) stops bacterial growth by binding to the bacterial ribosome (blocking peptidyl transferase) and inhibiting protein synthesis.
Levoptin (Naphazoline Hydrochloride) OPHTHALMIC SOLUTION USP, 0.1%
Naphazoline HCl, an ocular vasoconstrictor, is an imidazoline derivative sympathomimetic amine. The active ingredient is represented by the structural formula:
Chemical Name:2-(1-naphthylmethyl)-2-imidazoline monohydrochlorideVASOCON REGULAR ophthalmic solution is a sterile solution containing 1 mg/mL Levoptin (Naphazoline Hydrochloride) in an isotonic solution containing polyethylene glycol 8000, sodium chloride, polyvinyl alcohol, edetate disodium and purified water; preserved with benzalkonium chloride. Hydrochloric acid and/or sodium hydroxide added to adjust pH. It has a pH of 5.5 to 7.0.CLINICAL PHARMACOLOGY
Naphazoline constricts the vascular system of the conjunctiva. It is presumed that this effect is due to direct stimulation action of the drug upon the alpha adrenergic receptors in the arterioles of the conjunctiva resulting in decreased conjunctival congestion. Naphalozine belongs to the imidazoline class of sympathomimetics.
INDICATIONS AND USAGE
Levoptin (Naphazoline Hydrochloride) REGULAR is indicated for use as a topical ocular vasoconstrictor.
Contraindicated in the presence of an anatomically narrow angle or in narrow angle glaucoma or in persons who have shown hypersensitivity to any component of this preparation.
Patients under therapy with MAO inhibitors may experience a severe hypertensive crisis if given a sympathomimetic drug. Use in children, especially infants, may result in CNS depression leading to coma and marked reduction in body temperature.
Use with caution in the presence of hypertension, cardiovascular abnormalities, hyperglycemia (diabetes), hyperthyroidism, ocular infection or injury and when other medications are being used.
Patients should be advised to discontinue the drug and consult a physician if relief is not obtained within 48 hours of therapy, if irritation, blurring, or redness persists or increases, or if symptoms of systemic absorption occur, i.e., dizziness, headache, nausea, decrease in body temperature, or drowsiness.
To prevent contaminating the dropper tip and solution, do not touch the eyelids or the surrounding area with the dropper tip of the bottle. If solution changes color or becomes cloudy, do not use.Drug Interactions
Concurrent use of maprotiline or tricyclic antidepressants and naphazoline may potentiate the pressor effect of naphazoline. Patients under therapy with MAO inhibitors may experience a severe hypertensive crisis if given a sympathomimetic drug..
Pregnancy Category C
Animal reproduction studies have not been conducted with naphazoline. It is also not known whether naphazoline can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Naphazoline should be given to a pregnant woman only if clearly needed.
If is not known whether naphazoline is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when naphazoline is administered to a nursing woman.
Safety and effectiveness in children have not been established. See “WARNINGS” and “CONTRAINDICATIONS”.
Mydriasis, increased redness, irritation, discomfort, blurring, punctate keratitis, lacrimation, increased intraocular pressure.

Prednisolone Sodium Phosphate:
Levoptin is a glucocorticosteroid (GCS). This medication inhibits the function of leukocytes and tissue macrophages. Levoptin (Prednisolone Sodium Phosphate) restricts the migration of leukocytes in the area of inflammation. This drug violates the ability of macrophages to phagocytosis and the formation of interleukin-1. Levoptin (Prednisolone Sodium Phosphate) contributes to the stabilization of lysosomal membranes, thereby reducing the concentration of proteolytic enzymes in inflammation. This medicine decreases capillary permeability caused by histamine release. Levoptin (Prednisolone Sodium Phosphate) inhibits the activity of fibroblasts and collagen formation.
Levoptin (Prednisolone Sodium Phosphate) inhibits the activity of phospholipase A2 which leads to suppression of the synthesis of prostaglandins and leukotrienes. This medication inhibits the release of COX (especially COX-2), which also helps reduce the production of prostaglandins.
Levoptin (Prednisolone Sodium Phosphate) reduces the number of circulating lymphocytes (T-and B-cells), monocytes, eosinophils and basophils as a result of their displacement from the bloodstream into lymphoid tissue; suppresses the formation of antibodies.
Levoptin (Prednisolone Sodium Phosphate) inhibits the release of pituitary ACTH and beta-lipotropina but it does not reduces the level of circulating beta-endorphin. This drug also inhibits the secretion of TSH and FSH.
Levoptin (Prednisolone Sodium Phosphate) has a vasoconstrictor effect with direct application to the vessels.
Levoptin (Prednisolone Sodium Phosphate) has a pronounced dose-dependent effect on the metabolism of carbohydrates, proteins and fats. It stimulates gluconeogenesis, amino acid contributes to the capture of the liver and kidneys and increases the activity of enzymes of gluconeogenesis. In the liver, Levoptin (Prednisolone Sodium Phosphate) enhances the deposition of glycogen by stimulating the activity of glikogensintetazy and synthesis of glucose from the products of protein metabolism. This medicine increases blood glucose activates the secretion of insulin.
Levoptin (Prednisolone Sodium Phosphate) inhibits glucose uptake by fat cells that leads to the activation of lipolysis. However, due to an increase in insulin secretion is stimulated lipogenesis which contributes to the accumulation of fat.
Levoptin (Prednisolone Sodium Phosphate) also has catabolic effects in lymphoid and connective tissue, muscle, adipose tissue, skin, bone tissue. To a lesser extent than hydrocortisone Levoptin (Prednisolone Sodium Phosphate) affects the processes of water and electrolyte metabolism: promotes the excretion of potassium and calcium, delay in the body of sodium and water. Osteoporosis and Itsenko-Cushing's syndrome are the main factors limiting the long-term therapy with corticosteroids. As a result of the catabolic actions it may suppress growth in children.
In high doses prednisone can increase the excitability of brain tissue and contributes to lowering the threshold of convulsive readiness. This medication stimulates the excessive production of hydrochloric acid and pepsin in the stomach which leads to the development of peptic ulcers.
When systemic use the therapeutic activity of Levoptin (Prednisolone Sodium Phosphate) is due to anti-inflammatory, antiallergic, immunosuppressive and antiproliferative action.
For external and local application the therapeutic activity of Levoptin (Prednisolone Sodium Phosphate) is due to anti-inflammatory, antiallergic and antiexudative (due to vasoconstrictor effect) effect.
As compared with hydrocortisone the anti-inflammatory activity of Levoptin (Prednisolone Sodium Phosphate) is 4 times greater, the mineralocorticoid activity is 0.6 times smaller.
After oral administration Levoptin (Prednisolone Sodium Phosphate) is well absorbed from the gastrointestinal tract. Cmax in plasma observed after 90 min. In plasma most of Levoptin (Prednisolone Sodium Phosphate) is associated with transcortin (cortisol binding globulin). This drug metabolized primarily in the liver.
T1/2 is about 200 minutes.
