Pegaptanib, a new inhibitor of ocular neovascularization, provides patients with an alternative to photodynamic therapy with verteporfin and offers a novel approach to future drug developments for AMD. Pegaptanib offers the advantage of not requiring photodynamic therapy in conjunction with drug delivery and may be a viable option for institutions where this service is not easily accessible. Results of clinical trials have shown that pegaptanib is effective in delaying progression of AMD.

Lercanidipine may be an option in the treatment of hypertension, as current literature suggests comparable antihypertensive efficacy and better tolerability. Further randomized, double-blind clinical trials must be conducted in order to clarify its position among other antihypertensive medications.

Nifedipine is a dihydropyridine calcium-channel blocker (CCB) introduced approximately 30 years ago for the prophylaxis of angina symptoms, and then later utilized as an anti-hypertensive agent. In the 1990s, several meta-analyses and a case-control study were published which raised concern regarding increased mortality and increased risk for myocardial infarction with short-acting nifedipine. Further evaluation of these meta-analyses and case control study underscores some important limitations and the need to further elucidate the role of this class of medications in high-risk patients. Until 2000, there was a paucity of data on the long-term effects as well as the long-term outcomes of CCBs in the treatment of stable coronary disease or in patients with manifestations of the disease such as hypertension or angina. While it has been well established that nifedipine and other dihydropyridines lower blood pressure and improve symptoms of angina, several studies were designed to evaluate the effect of dihydropyridines on “hard” outcomes, specifically cardiovascular and cerebrovascular events. In this review, we describe the clinical studies evaluating the use of nifedipine when compared to placebo as well as other anti-hypertensive therapies in an attempt to identify the most appropriate place in therapy for this class of medications and to further clarify its utilization in high-risk patients.

Students who received faculty- mediated interventions designed to inform them about PGT were not significantly more likely to pursue such training than students who did not receive the interventions. However, students reported the information to be helpful.
