Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 46708-545-05, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 46708-0545-05, written without dashes as 46708054505. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 46708-0545-05, the first segment (46708) is the labeler code FDA assigned to Alembic Pharmaceuticals Limited; the middle segment (0545) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (05) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Alembic Pharmaceuticals Limited. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Alembic Pharmaceuticals Limited is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.

🎯 Indications and Usage 26 words ▾

INDICATIONS AND USAGE Timolol maleate ophthalmic gel forming solution is indicated in the treatment of elevated intraocular pressure in patients with ocular hypertension or open-angle glaucoma.

⏱️ Dosage and Administration ~1 min read ▾

DOSAGE AND ADMINISTRATION Patients should be instructed to invert the closed container and shake once before each use. It is not necessary to shake the container more than once. Other topically applied ophthalmic medications should be administered at least 10 minutes before Timolol maleate ophthalmic gel forming solution [see PRECAUTIONS, Information for Patients and accompanying INSTRUCTIONS FOR USE ].

Timolol maleate ophthalmic gel forming solution is available in concentrations of 0.25% and 0.5%. The dose is one drop of Timolol maleate ophthalmic gel forming solution (either 0.25% or 0.5%) in the affected eye(s) once a day. Because in some patients the pressure-lowering response to Timolol maleate ophthalmic gel forming solution may require a few weeks to stabilize, evaluation should include a determination of intraocular pressure after approximately 4 weeks of treatment with Timolol maleate ophthalmic gel forming solution.

Dosages higher than one drop of 0.5% Timolol maleate ophthalmic gel forming solution once a day have not been studied. If the patient's intraocular pressure is still not at a satisfactory level on this regimen, concomitant therapy can be considered. The concomitant use of two topical beta-adrenergic blocking agents is not recommended [see PRECAUTIONS , Drug Interactions, Beta-adrenergic blocking agents ].

When patients have been switched from therapy with TIMOPTIC administered twice daily to Timolol maleate ophthalmic gel forming solution administered once daily, the ocular hypotensive effect has remained consistent.

⛔ Contraindications 64 words ▾

CONTRAINDICATIONS Timolol maleate ophthalmic gel forming solution is contraindicated in patients with (1) bronchial asthma; (2) a history of bronchial asthma; (3) severe chronic obstructive pulmonary disease [see WARNINGS, Obstructive Pulmonary Disease ]; (4) sinus bradycardia; (5) second or third degree atrioventricular block; (6) overt cardiac failure [see WARNINGS, Cardiac Failure ]; (7) cardiogenic shock; or (8) hypersensitivity to any component of this product.

⚠️ Warnings ~2 min read ▾

WARNINGS As with many topically applied ophthalmic drugs, this drug is absorbed systemically. The same adverse reactions found with systemic administration of beta­ adrenergic blocking agents may occur with topical ophthalmic 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 [see CONTRAINDICATIONS ].

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. 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, Timolol maleate ophthalmic gel forming solution should be discontinued.

Obstructive Pulmonary Disease 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 Timolol maleate ophthalmic gel forming solution is contraindicated [see CONTRAINDICATIONS ] should, in general, not receive beta-blockers, including Timolol maleate ophthalmic gel forming 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 anesthesia in surgical procedures. Some patients receiving beta­ adrenergic receptor blocking agents have experienced protracted, severe hypotension during anesthesia.

Difficulty in restarting and maintaining the heartbeat has also been reported. For these reasons, in patients undergoing elective surgery, some authorities recommend 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.

Diabetes Mellitus Beta-adrenergic blocking agents should be administered with caution in patients subject to spontaneous hypoglycemia or to diabetic patients (especially those with labile diabetes) who are receiving insulin or oral hypoglycemic agents. Beta-adrenergic receptor blocking agents may mask the signs and symptoms of acute hypoglycemia. 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.

🤒 Adverse Reactions ~2 min read ▾

ADVERSE REACTIONS In clinical trials, transient blurred vision upon instillation of the drop was reported in approximately one in three patients (lasting from 30 seconds to 5 minutes). Less than 1% of patients discontinued from the studies due to blurred vision. The frequency of patients reporting burning and stinging upon instillation was comparable between Timolol maleate ophthalmic gel forming solution and TIMOPTIC (approximately one in eight patients).

Adverse experiences reported in 1-5% of patients were: Ocular: Pain, conjunctivitis, discharge (e.g., crusting), foreign body sensation, itching and tearing; Systemic: Headache, dizziness, and upper respiratory infections. The following additional adverse experiences have been reported with the ocular administration of this or other timolol maleate formulations: BODY AS A WHOLE Asthenia/fatigue, and chest pain. CARDIOVASCULAR Bradycardia, arrhythmia, hypotension, hypertension, syncope, heart block, cerebrovascular accident, cerebral ischemia, cardiac failure, worsening of angina pectoris, palpitation, cardiac arrest, pulmonary edema, edema, claudication, Raynaud's phenomenon, and cold hands and feet.

DIGESTIVE Nausea, diarrhea, dyspepsia, anorexia, and dry mouth. IMMUNOLOGIC Systemic lupus erythematosus. NERVOUS SYSTEM/PSYCHIATRIC Increase in signs and symptoms of myasthenia gravis, paresthesia, somnolence, insomnia, nightmares, behavioral changes and psychic disturbances including depression, confusion, hallucinations, anxiety, disorientation, nervousness, and memory loss.

SKIN Alopecia and psoriasiform rash or exacerbation of psoriasis. HYPERSENSITIVITY Signs and symptoms of systemic allergic reactions including anaphylaxis, angioedema, urticaria, localized and generalized rash. RESPIRATORY Bronchospasm (predominantly in patients with preexisting bronchospastic disease), respiratory failure, dyspnea, nasal congestion, cough and upper respiratory infections.

ENDOCRINE Masked symptoms of hypoglycemia in diabetic patients [see WARNINGS, Diabetes Mellitus ]. SPECIAL SENSES Signs and symptoms of ocular irritation including blepharitis, keratitis, and dry eyes; ptosis; decreased corneal sensitivity; cystoid macular edema; visual disturbances including refractive changes and diplopia; pseudopemphigoid; choroidal detachment following filtration surgery [see PRECAUTIONS, General ]; and tinnitus. UROGENITAL Retroperitoneal fibrosis, decreased libido, impotence, and Peyronie's disease.

The following additional adverse effects have been reported in clinical experience with ORAL timolol maleate or other ORAL beta-blocking agents and may be considered potential effects of ophthalmic timolol maleate: Allergic: Erythematous rash, fever combined with aching and sore throat, laryngospasm with respiratory distress; Body as a Whole: Extremity pain, decreased exercise tolerance, weight loss; Cardiovascular: Worsening of arterial insufficiency, vasodilatation; Digestive: Gastrointestinal pain, hepatomegaly, vomiting, mesenteric arterial thrombosis, ischemic colitis; Hematologic: Nonthrombocytopenic purpura, thrombocytopenic purpura, agranulocytosis; Endocrine: Hyperglycemia, hypoglycemia; Skin: Pruritus, skin irritation, increased pigmentation, sweating; Musculoskeletal: Arthralgia; Nervous System/Psychiatric: Vertigo, local weakness, diminished concentration, reversible mental depression progressing to catatonia, an acute reversible syndrome characterized by disorientation for time and place, emotional lability, slightly clouded sensorium, and decreased performance on neuropsychometrics; Respiratory: Rales, bronchial obstruction; Urogenital: Urination difficulties.

🔄 Drug Interactions ~1 min read ▾

Drug Interactions Beta-Adrenergic Blocking Agents Patients who are receiving a beta-adrenergic blocking agent orally and Timolol maleate ophthalmic gel forming solution should be observed for potential additive effects of beta-blockade, both systemic and on intraocular pressure. The concomitant use of two topical beta-adrenergic blocking agents is not recommended. Calcium Antagonists Caution should be used in the coadministration of beta-adrenergic blocking agents, such as Timolol maleate ophthalmic gel forming solution, and oral or intravenous calcium antagonists because of possible atrioventricular conduction disturbances, left ventricular failure, or hypotension.

In patients with impaired cardiac function, coadministration should be avoided. Catecholamine-Depleting Drugs Close observation of the patient is recommended when a beta blocker is administered to patients receiving catecholamine-depleting drugs such as reserpine, because of possible additive effects and the production of hypotension and/or marked bradycardia, which may result in vertigo, syncope, or postural hypotension. Digitalis and Calcium Antagonists The concomitant use of beta-adrenergic blocking agents with digitalis and calcium antagonists may have additive effects in prolonging atrioventricular conduction time.

CYP2D6 Inhibitors Potentiated systemic beta-blockade (e.g., decreased heart rate, depression) has been reported during combined treatment with CYP2D6 inhibitors (e.g. quinidine, SSRIs) and timolol. Clonidine Oral beta-adrenergic blocking agents may exacerbate the rebound hypertension which can follow the withdrawal of clonidine. There have been no reports of exacerbation of rebound hypertension with ophthalmic timolol maleate.

🤰 Pregnancy 149 words ▾

Pregnancy Teratogenic Effects Teratogenicity studies with timolol in mice, rats, and rabbits at oral doses up to 50 mg/kg/day (7,000 times the systemic exposure following the maximum recommended human ophthalmic dose) demonstrated no evidence of fetal malformations. Although delayed fetal ossification was observed at this dose in rats, there were no adverse effects on postnatal development of offspring. Doses of 1000 mg/kg/day (142,000 times the systemic exposure following the maximum recommended human ophthalmic dose) were maternotoxic in mice and resulted in an increased number of fetal resorptions.

Increased fetal resorptions were also seen in rabbits at doses of 14,000 times the systemic exposure following the maximum recommended human ophthalmic dose, in this case without apparent maternotoxicity. There are no adequate and well-controlled studies in pregnant women. Timolol maleate ophthalmic gel forming solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

🧒 Pediatric Use 61 words ▾

Pediatric Use Safety and effectiveness of timolol maleate ophthalmic solution have been established when administered in pediatric patients aged 2 years and older. Use of timolol maleate ophthalmic solution in these children is supported by evidence from adequate and well-controlled studies in children and adults. Safety and efficacy in pediatric patients below the age of 2 years have not been established.

🧓 Geriatric Use 17 words ▾

Geriatric Use No overall differences in safety or effectiveness have been observed between elderly and younger patients.

🆘 Overdosage 162 words ▾

OVERDOSAGE No data are available in regard to human overdosage with or accidental oral ingestion of Timolol maleate ophthalmic gel forming solution. There have been reports of inadvertent overdosage with TIMOPTIC Ophthalmic Solution resulting in systemic effects similar to those seen with systemic beta­ adrenergic blocking agents such as dizziness, headache, shortness of breath, bradycardia, bronchospasm, and cardiac arrest [see ADVERSE REACTIONS ]. Overdosage has been reported with timolol maleate tablets.

A 30-year-old female ingested 650 mg of timolol maleate tablets (maximum recommended oral daily dose is 60 mg) and experienced second and third degree heart block. She recovered without treatment but approximately two months later developed irregular heartbeat, hypertension, dizziness, tinnitus, faintness, increased pulse rate, and borderline first degree heart block. An in vitro hemodialysis study, using 14 C timolol added to human plasma or whole blood, showed that timolol was readily dialyzed from these fluids; however, a study of patients with renal failure showed that timolol did not dialyze readily.

🧬 Clinical Pharmacology ~2 min read ▾

CLINICAL PHARMACOLOGY Mechanism of Action 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 anesthetic (membrane-stabilizing) activity. Timolol maleate ophthalmic gel forming solution, when applied topically on the eye, has the action of reducing elevated, as well as normal intraocular pressure, whether or not accompanied by glaucoma. Elevated intraocular pressure is a major risk factor in the pathogenesis of glaucomatous visual field loss and optic nerve damage.

The precise mechanism of the ocular hypotensive action of Timolol maleate ophthalmic gel forming solution is not clearly established at this time. Tonography and fluorophotometry studies of TIMOPTIC ® (timolol maleate ophthalmic solution) in man suggest that its predominant action may be related to reduced aqueous formation. However, in some studies, a slight increase in outflow facility was also observed.

Beta-adrenergic receptor blockade reduces cardiac output in both healthy subjects and patients with heart disease. In patients with severe impairment of myocardial function, beta-adrenergic receptor blockade may inhibit the stimulatory effect of the sympathetic nervous system necessary to maintain adequate cardiac function. Beta-adrenergic receptor blockade in the bronchi and bronchioles results in increased airway resistance from unopposed parasympathetic activity.

Such an effect in patients with asthma or other bronchospastic conditions is potentially dangerous. Pharmacokinetics In a study of plasma drug concentration in six subjects, the systemic exposure to timolol was determined following once daily administration of Timolol maleate ophthalmic gel forming solution 0.5% in the morning. The mean peak plasma concentration following this morning dose was 0.28 ng/mL.

Clinical Studies In controlled, double-masked, multicenter clinical studies, comparing Timolol maleate ophthalmic gel forming solution 0.25% to TIMOPTIC 0.25% and Timolol maleate ophthalmic gel forming solution 0.5% to TIMOPTIC 0.5%, Timolol maleate ophthalmic gel forming solution administered once a day was shown to be equally effective in lowering intraocular pressure as the equivalent concentration of TIMOPTIC administered twice a day. The effect of timolol in lowering intraocular pressure was evident for 24 hours with a single dose of Timolol maleate ophthalmic gel forming solution.

Repeated observations over a period of six months indicate that the intraocular pressure-lowering effect of Timolol maleate ophthalmic gel forming solution was consistent. The results from the largest U.S. and international clinical trials comparing Timolol maleate ophthalmic gel forming solution 0.5% to TIMOPTIC 0.5% are shown in Figure 1. Figure 1 Mean IOP and Std Deviation (mm Hg) by Treatment Group Timolol maleate ophthalmic gel forming solution administered once daily had a safety profile similar to that of an equivalent concentration of TIMOPTIC administered twice daily.

Due to the physical characteristics of the formulation, there was a higher incidence of transient blurred vision in patients administered Timolol maleate ophthalmic gel forming solution. A slight reduction in resting heart rate was observed in some patients receiving Timolol maleate ophthalmic gel forming solution 0.5% (mean reduction 24 hours post-dose 0.8 beats/minute, mean reduction 2 hours post-dose 3.8 beats/minute) [see ADVERSE REACTIONS ]. Timolol maleate ophthalmic gel forming solution has not been studied in patients wearing contact lenses. timolol-gfs-figure-1 timolo-gfs-figure-2

It is a white, odorless, crystalline powder which is soluble in water, methanol, and alcohol.

Timolol maleate ophthalmic gel forming solution is supplied as a sterile, isotonic, buffered, aqueous solution of timolol maleate in two dosage strengths. The pH of the solution is approximately 7.0, and the osmolarity is 260-330 mOsm. Each mL of Timolol maleate ophthalmic gel forming solution 0.25% contains 2.5 mg of timolol (3.4 mg of timolol maleate).

Each mL of Timolol maleate ophthalmic gel forming solution 0.5% contains 5 mg of timolol (6.8 mg of timolol maleate). Inactive ingredients: gellan gum, tromethamine, mannitol, and water for injection. Preservative: benzododecinium bromide 0.012%.

The gel forming solution contains a purified anionic heteropolysaccharide derived from gellan gum. An aqueous solution of gellan gum, in the presence of a cation, has the ability to gel. Upon contact with the precorneal tear film, Timolol maleate ophthalmic gel forming solution forms a gel that is subsequently removed by the flow of tears. timolol-gfs-structure

💬 Information for Patients ~1 min read ▾

Information for Patients Patients should be instructed to avoid allowing the tip of the dispensing container to contact the eye or surrounding structures. Patients should also be instructed that ocular solutions, if handled improperly or if the tip of the dispensing container contacts the eye or surrounding structures, can become contaminated by common bacteria known to cause ocular infections. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions [see PRECAUTIONS, General ].

Patients should also be advised that if they have ocular surgery or develop an intercurrent ocular condition (e.g., trauma or infection), they should immediately seek their physician's advice concerning the continued use of the present multidose container. Patients should be instructed to invert the closed container and shake once before each use. It is not necessary to shake the container more than once.

Patients requiring concomitant topical ophthalmic medications should be instructed to administer these at least 10 minutes before instilling Timolol maleate ophthalmic gel forming solution. Patients with bronchial asthma, a history of bronchial asthma, severe chronic obstructive pulmonary disease, sinus bradycardia, second or third degree atrioventricular block, or cardiac failure should be advised not to take this product [see CONTRAINDICATIONS ]. Transient blurred vision, generally lasting from 30 seconds to 5 minutes, following instillation, and potential visual disturbances may impair the ability to perform hazardous tasks such as operating machinery or driving a motor vehicle.
