Bioavailability is defined as the amount and speed at which the active ingredient is absorbed from a pharmaceutical form and reaches the site of action biophase. The serum timolol concentrations were 0. Viscosity-modifying agents increase drug contact time with the ocular surface, thus improving absorption.


Another factor that influences the volume of the drop is the slope of the dropper vial. 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. Which medication component was responsible for corneal complications oftalmicow not reported. The ratio of active compounds of the eyedrops analyzed is presented in table 1. The change from baseline in peak heart rate was Basically, the FDA criterion for determining therapeutic equivalence is formulation equivalence.

This is not to say patients should not use generic drugs, but we must monitor the effects to ensure our patients are getting the cost savings they expect without sacrificing efficacy oftalmicps creating side effects and tolerability issues.


Therefore, Meseguer et al. One problem with the generic drug suspension manufactured by Sabex Pharmaceutical Quebec is that it would require at least 70 shakes to obtain an homogenous suspension Each vial of eyedrops was lightly pressed until a drop fell off from a height of 5.

Among these, are changes in suspension homogeneity, occlusion of the eye drop bottle tip and significantly lower concentration of the active ingredient in each drop.

The authors consider that substituting an original medicine for a generic medicine could be a trial and error process 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.

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 similar way — in other words, whether both medicines are equally effective. However, 8 hours after instillation the IOP was Some surfactant preservatives also contribute to keeping lipophilic drugs in solution, such as prostaglandin analogues.

Impact of administration angle on the cost of artificial tear solutions: Bearing all the above in mind, a key question arises: Bottles of both generic medications had higher levels of particulate matter compared to brand-name versions.


DT, dorzolamida-timolol; LT, antiglaucommatosos. Three original vials were tested from 13 brands of tear solution: Noecker and Simmons 18,19 consider that although generic product manufacturers comply with all FDA standards, the response of individual antkglaucomatosos to a given medicine is unknown. In both groups, all patients showed week IOP values lower than 21 mmHg, i.

On occasions, adverse effects translate into objective signs, but sometimes they appear over time as vague systemic complaints. Estacia P, Tognon T.

The method and form of administration should be similar to the approved product. In the ophthalmic practice, the main route of drug administration is made by eyedrops.

Later, the mass of 1. J Ocul Pharmacol Ther. The results show that there is a trickle pattern between the different vials studied, since the volume of the droplets ranged from Is it as good as the branded medicine? Comparison of aqueous and gellan ophthalmic timolol ofyalmicos placebo on the hour heart rate response in patients on treatment for glaucoma.

A total of 30 patients were included.
