Diquafosol tetrasodium was well tolerated and was superior to placebo (vehicle) in reducing corneal staining and in relieving certain patient symptoms. Diquafosol has a favorable risk/benefit profile in a broad spectrum of patients with dry eye disease and is a novel topical treatment of dry eye.

ObjectiveTo determine the efficacy, tolerability, and safety of ascending doses of Adhesive Dermally-Applied Microarray (ADAM) zolmitriptan versus placebo for acute migraine treatment.BackgroundADAM is a novel patient-administered system for intracutaneous drug administration. In a phase 1 pharmacokinetic study, zolmitriptan administered using ADAM had much faster absorption than oral administration with higher exposure in the first two hours.MethodsThis was a multicenter, randomized, double-blind, placebo-controlled, parallel-group Phase 2b/3 study evaluating ADAM zolmitriptan 1 mg, 1.9 mg, and 3.8 mg versus placebo. Co-primary endpoints were pain freedom and freedom from most bothersome other migraine-associated symptom 2 hours post-dose.ResultsOf patients treated with ADAM zolmitriptan 3.8 mg or placebo, 41.5% and 14.2%, respectively were pain-free 2 hours post-dose (p = 0.0001) and 68.3% and 42.9% were free from their most bothersome other symptom (p = 0.0009). Due to the fixed sequential testing methodology, formal statistical significance was not established for secondary endpoints. However, the proportion of patients who were photophobia-free, phonophobia-free, and nausea-free at 2 hours post-dose was higher in the ADAM zolmitriptan 3.8 mg group compared with placebo, as were the percentages of patients who were pain-free, and who experienced pain relief up to 48 hours post-dose. Systemic adverse events were consistent with previous triptan trials, and included dizziness, paresthesia, muscle tightness, and nausea, all of which occurred in < 5% of patients in any group. Application site reactions were generally mild and resolved within 48 hours, although erythema and bruising persisted for longer periods in some patients.ConclusionADAM zolmitriptan 3.8 mg provides effective relief of migraine headache and associated most bothersome symptoms compared with placebo, and is well-tolerated.ClinicalTrials.govNCT02745392

This study examined the ability of fluticasone propionate aerosol to reduce oral prednisone requirements in patients with severe asthma. Ninety-six patients dependent on oral prednisone were treated for 16 wk with placebo or fluticasone propionate aerosol (750 or 1,000 micrograms twice daily). Their dosage of oral prednisone was adjusted weekly according to predetermined criteria. A total of 69% and 88% of patients treated with fluticasone propionate 750 and 1,000 micrograms twice daily, respectively, compared with 3% of placebo-treated patients used no prednisone by the end of the study. In the fluticasone propionate groups, FEV1 and peak expiratory flow rates at the last evaluable visit/date improved and the number of night awakenings and symptomatic albuterol use declined relative to placebo values (p < 0.05). Patient-rated asthma symptoms improved in the groups receiving fluticasone propionate but not in the placebo group (p < 0.005). Fluticasone propionate aerosol was well-tolerated, and it improved some dimensions of health-related quality of life measured using a standard patient survey. Fluticasone propionate aerosol (750 or 1,000 micrograms twice daily) effectively and safely allowed most asthmatics dependent on oral corticosteroids to reduce or eliminate oral prednisone use while improving pulmonary function and quality of life.

Prazosin is an orally active post-synaptic selective alpha 1-adrenoreceptor antagonist that has been widely used in treating hypertension and congestive heart failure (CHF). Its role in the treatment of hypertension has previously been reviewed in this journal. Subsequent reports confirm its efficacy in treating mild to severe hypertension as a single agent or, more frequently, in combination with another antihypertensive agent and/or a diuretic. Recent studies of the metabolic effect of prazosin indicate that the drug may have a favourable effect on plasma lipids in hypertensive patients. Its recent use in treatment of congestive heart failure has shown prazosin to be comparable with nitroprusside in producing balanced arterial and venous dilation with generally sustained haemodynamic and clinical effects during long term therapy. Initial studies in Raynaud's phenomenon and in patients with aortic regurgitation or aortic stenosis or with mitral regurgitation are promising, but require confirmation from wider clinical experience. The drug has generally been well tolerated. The primary side effect of orthostatic hypotension can be largely avoided by beginning treatment with a low dose.
