Eficácia do travoprosta 0, 004% na redução da pressão intraocular em pacientes com glaucoma / Travoprosta 0, 004% efficacy in intraocular pressure in patients with glaucoma

Resumo Objetivo: avaliar a eficácia do colírio TRAVAMED® (travoprosta 0,004%) (Ofta, Brasil) na redução da pressão intraocular (PIO), em pacientes com glaucoma primário de ângulo aberto (GPAA) ou hipertensão ocular (HO), bem como avaliar os efeitos colaterais decorrentes do uso da droga. Métodos: estudo randomizado, controlado, com 70 olhos de 38 pacientes acima de 18 anos de idade, com diagnóstico de GPAA ou HO. Todos os pacientes receberam o colírio TRAVAMED® como primeira droga a ser introduzida no tratamento, tendo sido utilizada uma gota uma vez ao dia (à noite), e 30 dias após foram submetidos à tonometria de aplanação (Goldmann) para mensuração da PIO, com o mesmo examinador, no mesmo tonômetro e nos mesmos horários. Resultados: A média de redução da PIO após 30 dias de uso do TRAVAMED® foi de 7,46 mmHg. Em relação aos efeitos colaterais, 15,71% (11) dos olhos apresentaram hiperemia conjuntival, 8,57% (6) apresentaram dor, 8,57% (6) apresentaram ardência, 2,86% (2) apresentaram embaçamento visual e em 1,56% (1) dos olhos não houve queda significativa da PIO. Conclusão: A medicação TRAVAMED® foi eficiente na redução da PIO após 30 dias de uso contínuo, na dose de 1x/dia. Acerca dos efeitos colaterais, os mais observados foram hiperemia ocular (15,71%), dor (8,57%) e ardência (8,57%), porém estudos com maior tempo de seguimento se fazem necessários.

Abstract Objective: to evaluate how much decreases intraocular pressure (IOP) with TRAVAMED® (travoprost 0,004%) (Germed, Brazil) in patients with primary open angle glaucoma (POAG) and ocular hypertension (OH) and possible side effects. Methods: controlled and randomized study, it was evaluated 70 eyes of 38 patients with age of 18 years old or more diagnosed with POAG and OH. All the patients had TRAVAMED® as first drop for treatment used once daily (at night) and 30 days later they had IOP measured by Goldmann tonometry, with the same examiner in the same tonometer at the same times. Results: the mean decrease in IOP was 7,46 mmHg after 30 days using the drops. 15.71% (11) of eyes had conjunctival redness, 8.57% (6) had pain, 8.57% (6) had burning, 2.86% (2) had blurring vision and 1.56% (1) of the eyes there wasn't a significant reduction in IOP. Conclusion: TRAVAMED® was efficient when evaluating IOP decrease. The most correlated side effects were conjunctival redness (15.71%), pain (8.57%) and burning (8.57%), but studies with longer follow-up are needed.

Comparing the Efficacy of Latanoprost (0.005%), Bimatoprost (0.03%), Travoprost (0.004%), and Timolol (0.5%) in the Treatment of Primary Open Angle Glaucoma

PURPOSE: To compare the efficacy and safety of latanoprost, bimatoprost, travoprost and timolol in reducing intraocular pressure (IOP) in patients with primary open angle glaucoma. METHODS: This was a prospective study conducted at a tertiary-care centre. One hundred and forty patients with newly diagnosed primary open angle glaucoma were randomly assigned to treatment with latanoprost (0.005%), bimatoprost (0.03%), travoprost (0.004%) or timolol gel (0.5%); 35 patients were assigned to each group. All patients were followed for 2, 6, and 12 weeks. The main outcome measure studied was the change in IOP at week 12 from the baseline values. Safety measures included recording of adverse events. RESULTS: The mean IOP reduction from baseline at week 12 was significantly more with bimatoprost (8.8 mmHg, 35.9%) than with latanoprost (7.3 mmHg, 29.9%), travoprost (7.6 mmHg, 30.8%) or timolol (6.7 mmHg, 26.6%) (ANOVA and Student's t-tests, p < 0.001). Among the prostaglandins studied, bimatoprost produced a maximum reduction in IOP (-2.71; 95% confidence interval [CI], -2.25 to -3.18) followed by travoprost (-1.27; 95% CI, -0.81 to -1.27) and latanoprost (-1.25; 95% CI, -0.79 to -1.71); these values were significant when compared to timolol at week 12 (Bonferroni test, p < 0.001). Latanoprost and travoprost were comparable in their ability to reduce IOP at each patient visit. Ocular adverse-events were found in almost equal proportion in patients treated with bimatoprost (41.3%) and travoprost (41.9%), with a higher incidence of conjunctival hyperemia (24.1%) seen in the bimatoprost group. Timolol produced a significant drop in heart rate (p < 0.001) at week 12 when compared to the baseline measurements. CONCLUSIONS: Bimatoprost showed greater efficacy when compared to the other prostaglandins, and timolol was the most efficacious at lowering the IOP. Conjunctional hyperemia was mainly seen with bimatoprost. However, the drug was tolerated well and found to be safe.
