Dorzolamide, Timolol Maleate Description Dorzox Eye Drops (Dorzolamide) is used to treat intraocular pressure in patients with ocular hypertension or glaua. It is used by patients specifically in order to manage and alleviate the associated symptoms. Dosage and Administration Dorzox Eye Drops (Dorzolamide) are administered in the same way that most eye drops are. Patients prescribed this medication will usually be instructed to dispense 1 droplet into each affected eye, between 1 and 3 times each day. Immediately after applying the required eye drops, close the eye for 1 to 2 minutes to help the medicine distribute at the same time as applying gentle pressure to the inside corner of the eye. Dorzox Eye Drops (Dorzolamide) are usually very well tolerated and any side effects are only mild and short-lasting, however any you notice should be reported to your physician. Possible side effects include: Irritation Burning Stinging Dryness Blurry vision Increased sensitivity to lightDorzox-T Eye Drops - Uses, position, Dosage, Side Effects amp Reviews Dorzox-T is considered safe for the treatment of open angle glaua which reduces the intraocular pressure to cure the problem. This medication also cures ocular hypertension. This drug contains two ponents which are dorzolamide and timolol. These both work together to decrease the elevated intraocular pressure by reducing the aqueous humor secretion.
The higher the level of intraocular pressure, the greater the likelihood of glauatous field loss and optic nerve damage. The bined effect of these two agents administered as dorzolamide-timolol fixed dose bination resulting in additional intraocular pressure reduction. Now save your gradually decreasing vision due to open angle glaua with the use of Dorzox-T. Buy it online at discounted prices from us. Dorzox-T Eye Drops Uses Dorzolamide . It acts as an inhibitor of human carbonic anhydrase II. Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. Timolol . It acts as adrenergic receptor blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant or local anesthetic activity.

Description DORZOX-T ophthalmic solution is prised of two ponents: dorzolamide hydrochloride and timolol maleate.
Each of these two ponents decreases elevated intraocular pressure, whether or not associated with glaua, by reducing the aqueous humour secretion. Elevated intraocular pressure is a major risk factor in the pathogenesis of optic nerve damage and glauatous visual field loss. The higher the level of intraocular pressure, the greater the likelihood of glauatous field loss and optic nerve damage. Pharmacodynamics DORZOX-T is prised of two ponents: dorzolamide hydrochloride and timolol maleate. Dorzolamide hydrochloride is an inhibitor of human carbonic anhydrase-II. Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humour secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport. Timolol maleate is a beta 1 and beta 2 (non-selective) adrenergic receptor blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anaesthetic (membrane-stabilizing) activity. The bined effect of these two agents administered as dorzolamide-timolol fixed dose bination ophthalmic solution b. i.d. results in additional intraocular pressure reduction pared to either ponent administered alone, but the reduction is not as much as when dorzolamide t. i.d. and timolol b. i.d. are administered conitantly. This medicinal product reduces intra-ocular pressure without the mon side effects of miotics such as night blindness, acmodative spasm and pupillary constriction. Pharmacokinetics Dorzolamide Hydrochloride Indications Dosage and Administration Contraindications Reactive airway disease Bronchial asthma A history of bronchial asthma Severe chronic obstructive pulmonary disease Sinus bradycardia Sino-atrial block Second or third degree atrioventricular block not controlled with the pacemaker Overt cardiac failure Cardiogenic shock Severe renal impairment (CrCl Hypersensitivity to any ponent of this product Warnings and Precautions While taking beta-blockers, patients with a history of atopy or a history of severe anaphylactic reactions to a variety of allergens may be more reactive to repeated accidental, diagnostic or therapeutic challenge with such allergens.
Such patients may be unresponsive to the usual doses of epinephrine used to treat anaphylactic reactions. In clinical studies, local ocular adverse effects, primarily conjunctivitis and lid reactions, were reported with chronic administration of dorzolamide - timolol fixed dose bination ophthalmic solution. Many of these reactions had the clinical appearance and course of an allergic-type reaction that resolved upon discontinuation of drug therapy. If such reactions are observed, Dorzolamide-timolol fixed dose bination ophthalmic solution should be discontinued and the patient evaluated before considering restarting the drug. Therapy with oral carbonic anhydrase inhibitors has been associated with urolithiasis as a result of acid-base disturbances, especially in patients with a prior history of renal calculi. Although no acid-base disturbances have been observed with this medicinal product, urolithiasis has been reported infrequently. Because Dorzolamide-timolol fixed dose bination ophthalmic solution contains a topical carbonic anhydrase inhibitor that is absorbed systemically, patients with a prior history of renal calculi may be at increased risk of urolithiasis while using this medicinal product. The management of patients with acute angle-closure glaua requires therapeutic interventions in addition to ocular hypotensive agents.
Dorzolamide-timolol fixed dose bination ophthalmic solution has not been studied in patients with acute angle-closure glaua. Choroidal detachment after filtration procedures has been reported with the administration of aqueous suppressant therapy (e. g. timolol). Beta-adrenergic blockade has been reported to potentiate muscle weakness consistent with certain myasthenic symptoms (e. g. diplopia, ptosis and generalized weakness). Timolol has been reported, rarely, to increase muscle weakness in some patients with myasthenia gravis or myasthenic symptoms. As with the use of other antiglaua medicines, diminished responsiveness to ophthalmic timolol maleate after prolonged therapy has been reported in some patients. However, in clinical studies in which 164 patients have been followed for at least 3 years, no significant difference in mean intraocular pressure has been observed after initial stabilization. There have been reports of bacterial keratitis associated with the use of multiple-dose containers of topical ophthalmic products.
These containers had been inadvertently contaminated by patients who, in most cases, had a concurrent corneal disease or a disruption of the ocular epithelial surface. Corneal oedema and irreversible corneal depensation have been reported in patients with pre-existing chronic corneal defects and/or a history of intraocular surgery while using dorzolamide. There is an increased potential for developing corneal oedema in patients with low endothelial cell counts topical dorzolamide - timolol fixed dose bination ophthalmic solution should be used with caution in such patients. Ophthalmic beta-blockers may induce dryness of eyes.
Patients with corneal diseases should be treated with caution. Patients should be advised that Dorzolamide-timolol fixed dose bination ophthalmic solution contains benzalkonium chloride, which may be absorbed by soft contact lenses. Contact lenses should be removed prior to administration of the solution. Lenses may be reinserted after 15 minutes following administration of Dorzolamide-timolol fixed dose bination ophthalmic solution. No studies on the effects on the ability to drive and use machines have been performed. Possible side effects such as blurred vision may affect some patients ability to drive and/or operate machinery. Systemic Exposure Dorzolamide-timolol fixed dose bination ophthalmic solution contains dorzolamide, a sulphonamide, and timolol maleate, a beta-adrenergic blocking agent and although administered topically, is absorbed systemically. Therefore, the same types of adverse reactions that are attributable to sulphonamides and/or systemic administration of beta-adrenergic blocking agents may occur with topical administration.
For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and, rarely, death in association with cardiac failure, have been reported following systemic or ophthalmic administration of timolol maleate. Fatalities have occurred, although rarely, due to severe reactions to sulphonamides, including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anaemia and other blood dyscrasias. Sensitization may recur when a sulphonamide is re-administered, irrespective of the route of administration. If signs of serious reactions or hypersensitivity occur, discontinue the use of this preparation. The following conitant medications are not remended: Dorzolamide and oral carbonic anhydrase inhibitors Use of two topical beta-adrenergic blocking agents Cardiac Failure Sympathetic stimulation may be essential for support of the circulation in individuals with diminished myocardial contractility, and its inhibition by beta-adrenergic receptor blockade may precipitate more severe failure. Because of the timolol maleate ponent, cardiac failure should be adequately controlled before beginning therapy with Dorzolamide-timolol fixed dose bination ophthalmic solution. Patients with a history of cardiovascular disease, including cardiac failure, should be watched for signs of deterioration of these diseases, and pulse rates should be checked.
Due to its negative effect on conduction time, beta-blockers should be given with caution to patients with first degree heart block. In patients without a history of cardiac failure continued depression of the myocardium with beta-blocking agents over a period of time can, in some cases, lead to cardiac failure. At the first sign or symptom of cardiac failure, Dorzolamide-timolol fixed dose bination ophthalmic solution should be discontinued. Obstructive Pulmonary Diseases Patients with chronic obstructive pulmonary disease (e. g. chronic bronchitis, emphysema) of mild or moderate severity, bronchospastic disease or a history of bronchospastic disease (other than bronchial asthma or a history of bronchial asthma, in which dorzolamide-timolol fixed dose bination ophthalmic solution is contraindicated, should, in general, not receive beta-blocking agents, including dorzolamide-timolol fixed dose bination ophthalmic solution. Major Surgery The necessity or desirability of withdrawal of beta-adrenergic blocking agents prior to major surgery is controversial. Beta-adrenergic receptor blockade impairs the ability of the heart to respond to beta-adrenergically mediated reflex stimuli. This may augment the risk of general anaesthesia in surgical procedures.
Some patients receiving beta-adrenergic receptor blocking agents have experienced protracted severe hypotension during anaesthesia. Difficulty in restarting and maintaining the heartbeat has also been reported. For these reasons, in patients undergoing elective surgery, some authorities remend gradual withdrawal of beta-adrenergic receptor blocking agents. If necessary during surgery, the effects of beta-adrenergic blocking agents may be reversed by sufficient doses of adrenergic agonists. Beta-blocking ophthalmological preparations may block systemic beta-agonist effects e. g. of adrenaline.
The anaesthesiologist should be informed when the patient is receiving timolol. Diabetes Mellitus Beta-adrenergic blocking agents should be administered with caution in patients subject to spontaneous hypoglycaemia or to diabetic patients (especially those with labile diabetes) who are receiving insulin or oral hypoglycaemic agents. Beta-adrenergic receptor blocking agents may mask the signs and symptoms of acute hypoglycaemia. Thyrotoxicosis Beta-adrenergic blocking agents may mask certain clinical signs (e. g. tachycardia) of hyperthyroidism. Patients suspected of developing thyrotoxicosis should be managed carefully to avoid abrupt withdrawal of beta-adrenergic blocking agents that might precipitate a thyroid storm. Vascular Disorders Patients with severe peripheral circulatory disturbance/disorders (e. g. severe forms of Raynauds disease or Raynauds syndrome) should be treated with caution.
