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.

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 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.
