In the absence of comparative studies between the brand-name and the generic medication, FDA classified the generic formulation of the timolol maleate gel forming solution Falcon Laboratories as ABalthough the products are formulated with different slow-release gel vehicles. Dosage variability of topical ocular hypotensive products: Bottles of both iftalmicos medications had higher levels of particulate matter compared to brand-name versions.

However, with the sign reversed, the bigger the drop the smaller number of droplets contained in vials will be, increasing the final cost to the consumer. Impact of administration angle on the cost of artificial tear solutions: As reported by the authors in the abstract, the study showed that the new product is non-inferior to the original product.

.: Portal da SBO – Sociedade Brasileira de Oftalmologia :.

A total of 30 patients were included. J Cataract Refract Surg. Thus, a drop of larger volume applied to a human eye will have its excess overflowed through the face and drained by the lacrimal pathways 2.

This causes the drug to achieve higher levels in the aqueous humour with the same oftalicos brimonidine 0.

Are generics and brand-name medicines the same?*

In the ophthalmic practice, the main route of drug administration is made by eyedrops. We used the highest volume presentation available of the brands studied: Since the effect is produced in mucous membranes or the skin, plasma concentrations are either not high enough to allow drug levels to be determined or, if high enough, they are too small and irregular.

Considering the therapeutic equivalence of tear solutions, the cost minimization analysis is a simple way of economic evaluation in which only the costs are subjected to comparisons because the efficacy or the effectiveness of the comparable alternatives are equal 11, Corneal complications were seen after instillation of diclofenac post-operatively after routine ophthalmic procedures.


As the eyedrop is instilled in the form of droplets, it must follow the specifications defined by ANVISA to administer liquid medications.

In sum, several researchers 12,14 have noted different problems in generic prednisolone acetate formulations, which were associated with suspension characteristics and forming of precipitates.

A comparison of active ingredients and preservatives between brand name and generic topical glaucoma medications using liquid chromatography-tandem mass spectrometry. Table 2 presents the results of the mass of 10 drops and 1 milliliter drop volume, the volume of the droplet formed, the volume of the largest presentation found in market for each brand, and the wholesale price of the eyedrops analyzed under different tilt angles of the bottle during application.

The eyedrops were open at the time of test, and the weighing of drops was held by the same researcher, being filed the batch of each vial.

What will be the repercussions on the daily practice of changing antiglaucomatous medications to generics? When patients ask about replacing a branded product with its generic counterpart, all we can honestly say as doctors is that the new generic medicine has not been studied, analysed or compared to the original medicine, and so we cannot know whether it will act in a antiglauucomatosos way — in other words, whether both medicines are equally effective.

The mean number of drops in each bottle was determined and a pharmacoeconomic evaluation of the drops was made.

Desai C, Rajadhyaksha V. Cantor 20 considers that when switching to a generic medicine, neither the patient not the physician can be sure that the new medicine will be well tolerated or effective. These differences are statistically significant.

Temperature affects active antjglaucomatosos concentration in eye drops. In face of the European Medicines Agency, why does the FDA require all active and inactive components of a generic ophthalmic medicine to be exactly the same as in the reference product?


Bearing all the above in mind, a key question arises: A local or topical action medicine is a product which is applied locally and assumed to act on the site where it is administered. Why do generics manufacturers not copy the original medicine exactly?

Are generics and brand-name medicines the same?* |

In this case, we are inclined to suggest that the patient try the generic. Clinical differences between generic and brand-name anti-inflammatory ophthalmic medications.

Further studies should be conducted antiglxucomatosos other classes of eyedrops, and we must worry each time more about the droplet volume of eyedrop, so that an ideal is reached.

The IOP was measured at 8 am trough effect and 2 and 8 hours after instillation. The increased basal active ingredient concentration could be a strategy to compensate the known degradation of drugs over time to levels below their optimal dose, including at room temperature. Considering the dosage of 1 drop in each eye four times a day, for a total of 8 drops a day, the average cost of the drop, the monthly and the annual cost of the treatment were estimated according to the wholesale price, which is the highest price at which a laboratory or distributor of medicines can sell their product in the Brazilian market.

The concept of pharmacoeconomics is growing nowadays, and concerns the application of lftalmicos principles of economics to the study of medications and health practices, aiming at the optimization in the use of financial resources without prejudice to quality and treatment outcomes For the analysis of the results, the products antiglaucomxtosos selected and randomly numbered for the definition of the sequence of data collection.
