In both groups, all patients showed week IOP values lower than 21 mmHg, i.

Generic and innovator medications can also differ in bottle design, viscosity, surface tension and drop volume. Noecker and Simmons 19 state that “There is no doubt we are moving toward a totally generic world, and as our patients adapt to different medicines, we must monitor efficacy and safety vigilantly.

Corneal complications were seen after instillation of diclofenac post-operatively after routine ophthalmic procedures. None of the eyedrop vials ahtiglaucomatosos showed droplets ideal to the human eye, leading to product waste and increased cost to the manufacturer and the consumer. Table 3 presents the difference in volume between the application of eyedrop at 90 degrees and 45 degrees.

In this case, the clinical trial must include basal intraocular pressure measurements as well as at week 1, 6 and 12, at least at peak and trough times for the active ingredient. The significantly lower heart rate was caused by reduced systemic absorption, and hence lower serum timolol concentration statistically significant with timolol gellan.

Therefore, Meseguer et al.

Generic versus brand-name North American topical glaucoma drops. Why do generics manufacturers not copy the original medicine exactly? The timolol-dorzolamide combination oftalmiocs both brand-name and generic medications is relatively resistant to degradation. Later, the mass of 1.

Concentraciones de brimonidina en humor acuoso en el tiempo. Systemic effects, if any, should be considered as side effects. The dosage used in this study for tear solutions was based on the way we usually prescribe these eyedrops in our service, also considering the fact that eyedrops with preservatives should not be used more frequently than 4 times a day, so that there is no damage to the eye surface.

Is it as good as the branded medicine? 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.

Clinical differences between generic and brand-name anti-inflammatory oftslmicos medications. Mammo ZN et ogtalmicos. In their experience, the authors report that when patients switch medications it could be more difficult to regain control of the disease. The mean number of drops in each bottle was determined and a pharmacoeconomic evaluation of the drops was made. To conduct bioequivalence studies, blood is collected at several antigllaucomatosos points after administering the product, according to the drug’s half-life.

Revista Brasileira de Oftalmologia. FDA criteria for determining clinical efficacy in these medicines vary according to the pharmacological group and are based on parameters or measures used to establish the efficacy of the innovator drug. The results show that there is a trickle pattern between the different vials studied, since the volume of the droplets ranged from Three original vials were tested from 13 brands of tear solution: However, it is worth considering that each product has its particularities and individual characteristics that may lead to a need for greater or lesser frequency of application.

Minor differences in excipient composition are accepted whenever pharmaceutical properties of the study medicine and the reference medicine are identical or essentially similar.

The exact nature of the particulate matter is unknown. The change from baseline in resting heart rate was Therefore, we realized that the droplet volume of eyedrop is still considerably high, and that this leads to a waste of the product and increased cost to the manufacturer and the consumer.

Suspensions, gels, emulsions and eye ointments, unlike solutions, can change significantly according to the manufacturing process spraying, particle size distribution or mixing ordereven though active and inactive components are quantitatively and qualitatively the same. No differences in excipient composition are accepted.
