Drug Exclusivity Exclusivity is the sole marketing rights prednisolone by the FDA pil a manufacturer upon the approval of a drug and may run simultaneously with a patent. Mechanisms of action of tablets. A randomized, crossover, open label pilot study to evaluate the efficacy and 25mg of Xalatan in comparison with generic latanoprost Latoprost in subjects with primary open angle glaucoma or ocular hypertension.
In the presence of tissue damage or an offending agent, neutrophils and monocytes recruit macrophages to remove the offending stimulus. The two classes of anti-inflammatory drugs each inhibit the inflammatory pathway differently. Corticosteroids The anti-inflammatory properties of corticosteroids are mediated at the genomic level.
Although the condition may not be completely resolved at the first follow up, I usually see a dramatic decrease in symptoms. If there is no improvement in patient symptoms or clinical signs, an astute clinician should investigate medication compliance and instillation.
As many of the corticosteroid options are in suspension form, failing to shake the bottle prior to instillation tends to be the culprit of delayed resolution. Additionally, the varying strengths of topical corticosteroids allow clinicians the option to increase the medication strength when little improvement is observed. Indications and Contraindications. Many of the adnexal and anterior segment inflammatory conditions can be successfully treated with topical steroid therapy.
This decrease in the immune system increases the risk for opportunistic infections. When you have concern for infectious etiologies, be cautious to initiate isolated corticosteroid therapy. As red eye presentations can often be difficult cases, consider the following before initiating therapy: Take a thorough case history that may preclude corticosteroid use, at least initially Instill vital dyes that may reveal an epithelial herpetic etiology Initiating Therapy.
New drug designs have increased corticosteroid potency and metabolism with decreased side effects. Ocular hypertension and a hastening of posterior subcapsular cataract formation are well documented in the literature with prolonged corticosteroid use. Additionally, visual acuity, IOP assessment and ophthalmoscopic evaluation of the optic nerve head at subsequent visits will ensure clinicians catch any possible side effects before they become vision threatening.

Durezol difluprednate 0. In one study, researchers found Durezol had superior dose uniformity compared with Pred Forte and its generic counterpart because of its emulsion formulation. In a comparative analysis of prednisolone acetate suspensions, one study found that Pred Forte exhibited greater homogeneity and bioavailability of the drug between doses compared with EconoPred Alcon and generic prednisolone acetate.
Available in generic formulations, Vexol and prednisolone phosphate sodium provide for cost-conscientious prescribing. Additionally, research found Vexol had equal efficacy in the treatment of anterior uveitis with a decreased chance of increasing IOP compared with Pred Forte. Ocular Surface. Retrometabolic drugs are currently used in the treatment of many systemic conditions.
After eliciting therapeutic benefit, the analog undergoes rapid degradation and metabolism, thereby decreasing the opportunity for adverse drug reactions. Both Lotemax 0. These alternatives are available in generic formulations and are lower in cost compared with their branded counterparts. Click images to enlarge. Inflammation of the eyelids and adnexa are common presentations, and a detailed history and thorough ophthalmoscopic evaluation should yield whether it is allergic in nature or of infectious etiology.
In cases of moderate to significant dermatologic inflammation, topical corticosteroids are warranted. Dermatologic presentations can be treated with ointment formulations an off-label use , such as Lotemax 0. Additionally, consider sulfa allergies prior to prescribing some of these alternatives. Ending Treatment. All corticosteroid therapy should be tapered to prevent any bouts of repeat inflammation.
Unfortunately, tapering schedules are more of an art than a science. There is no universally accepted tapering regimen in the literature other than defined improvement by the Standard Uveitic Nomenclature SUN group. Ultimately, the clinician is responsible for changing dosing schedules and the start of the taper based on clinical improvement and intuition. When a clinician inevitability encounters a reoccurrence of inflammation because a steroid is tapered too quickly, initial dosing schedule of the steroid is required.
NSAIDs Topical nonsteroidal anti-inflammatory therapy is used sparingly in the primary care setting, mostly to prevent and treat postoperative inflammation.
Generally, topical NSAIDs will be used in combination with maximal efficacy corticosteroids in the treatment of postoperative CME, typically in concert with the cataract surgeon. Clinicians should follow the recommended dosing to limit risk for side effects related to prolonged NSAID use. As with corticosteroid use, duration of use should be limited roughly one month.
Chronic use retards corneal epithelial healing and corneal melting and perforation, although extremely rare, are reported in the literature. Brand Drugs: Which is Better? By Edward Chu, O. Seems like an easy question with an obvious answer, right? However, should you be as cost-conscious?
Sometimes, you do indeed get what you pay for. On the other hand, generic drugs work well enough most of the time and they offer very real cost savings—not only to individual patients, but also to the health care system as a whole.
When is it best to prescribe the generic or the brand-name drug? Based on Bioequivalence While the initial brand-name company must submit to rigorous drug testing and lengthy clinical trials when applying to the Food and Drug Administration FDA , companies that produce generic medications merely submit to an abbreviated form of the approval process. Safety and efficacy do not have to be proven or established with generics because thorough testing on the branded medication has presumably already been conducted.
Companies merely have to show the FDA that their drugs are bioequivalent to the brand. Typically, this is accomplished by ensuring that the generic version releases its active ingredient in the bloodstream at the same speed and in the same amount as the branded drug.
Moreover, bloodstream concentrations of an ophthalmic medication applied directly to the eye are likely not important in assessing its efficacy. Most eye care providers likely remember the series of patients in the early s who experienced corneal melts associated with the use of generic diclofenac ophthalmic solution as opposed to the brand-name Voltaren after ocular surgery.
In one article, three in five patients who experienced a corneal melt were taking generic diclofenac, and four patients eventually progressed to corneal perforation that required a transplant. A study by the Schneider Institute for Health Policy at Brandeis University indicated that if generic usage was increased by Medicare recipients, there could be theoretical savings in billions of health care dollars.
This could effectively nullify the health care savings. Especially with glaucoma medications, some practitioners may be more inclined to bring patients back sooner to check the efficacy and tolerability of the generic medication than they normally would if no switch had occurred.
Due to the increasing number of generic manufacturers and the potential for differing efficacy between generics, one glaucoma specialist has gone as far as to recommend tracking each type of generic by having their patients bring in the bottles to each visit.
By doing this, he can track each type of generic and watch for patterns of efficacy and tolerability. We only need to look as far back as the issues related to Travatan travoprost, Alcon preserved with benzalkonium chloride BAK to see the possibility for problems with certain preservatives.
Producers of generic medications must follow manufacturing standards and comply with labeling regulations, which prohibit generic medication bottles from looking similar to their brand-name counterparts.
Currently, the generic ophthalmic medication making the most headlines is latanoprost 0. Although the generic may be less expensive and may provide significant savings, there is some concern that generic glaucoma medications do not have the same effect as their trade versions, and the result could be progression of the disease and loss of vision.
Previously, there had been only one other study conducted on a generic formulation of latanoprost in The investigators found that patients who were crossed over from Latoprost to Xalatan experienced a further decrease in IOP. Overall, the generic, which is formulated at a higher pH than the branded product, was found to be less efficacious at lowering IOP. Concerns have also been raised regarding the prescribing of the generic version of timolol gel-forming solution.
Researchers have shown that retention time on the ocular surface differs between various extended-release gel vehicles. Specifically, the gellan gum found in Timoptic-XE timolol maleate ophthalmic gel-forming solution, Merck may allow the brand-name medication to have longer surface contact, better absorption and beta-blocker activity intraocularly. Several studies and cases in recent years have also illustrated the need to exercise caution and vigilance when treating inflammation with ophthalmic steroids.
Allergan has noted in its memorandums to doctors that the micro-fine suspension in its Pred Forte prednisolone acetate is more uniform, remains longer in the conjunctival sac and minimizes mechanical irritation to the eye compared to generic prednisolone acetate.
The results of the study found that the generic form of prednisolone acetate had a greater tendency for particles to agglomerate, which subsequently led to inconsistent dosage concentration. In contrast, the particle sizes in Pred Forte were smaller and more uniform, which allowed them to stay in suspension longer and gave a more precise dosage of the drop.
