Non-selective β-blocker propranolol has been proved by FDA as the first-line agent for infantile hemangioma (IH) with dramatic response. To reduce the side effects caused by systemic administration of propranolol, timolol maleate treatment has been increasingly used as an alternative to systemic β-blockers and watchful waiting for many IH patients in recent years. However, the appropriate indications, drug dosage, dosing regimen, time for initiation, optimal duration, monitoring for side effects still remains controversial...

Timolol Maleate (TiM), a nonselective β-adrenergic blocker, is a potent highly effective agent for management of hypertension. The drug suffers from poor oral bioavailability (50%) due to its first pass effect and a short elimination half-life of 4 h; resulting in its frequent administration. Transdermal formulation may circumvent these problems in the form of protransfersomes. The aim of this study is to develop and optimize transdermal protransfersomal system of Timolol Maleate by film deposition on carrier method where protransfersomes were converted to transfersomes upon skin hydration following transdermal application under occlusive conditions...

BACKGROUND: Glaucoma is the international leading cause of irreversible blindness. Intraocular pressure (IOP) is the only currently known modifiable risk factor; it can be reduced by medications, incisional surgery, or laser trabeculoplasty (LTP). LTP reduces IOP by 25% to 30% from baseline, but early acute IOP elevation after LTP is a common adverse effect. Most of these IOP elevations are transient, but temporarily elevated IOP may cause further optic nerve damage, worsening of glaucoma requiring additional therapy, and permanent vision loss...

Glaucoma is a serious chronic ophthalmic disease since it causes irreversible visual disability if untreated can lead to blindness. Treatment options include medications (classified into five major classes of drugs which are muscarinic cholinergic agonists, alpha-2 adrenergic agonists, beta-1 adrenergic antagonists, prostaglandins [PGs], and carbonic anhydrase inhibitors); use of laser therapy or conventional surgery. Pharmacoeconomic analysis helps in choosing among this variety of treatments. There is a great need for such analysis in Egypt since undergoing of it in different countries or societies may produce different results...

Topical timolol and 595-nm pulsed dye laser (PDL) are both widely used in the treatment of superficial infantile hemangiomas (IH). However, to date, there is no reliable study comparing the therapeutic outcomes between the two treatment options. We designed the present study to evaluate and compare the efficacy and safety of timolol cream and PDL in the treatment of superficial proliferating IH. Twenty-one patients with superficial IH were included in the study. Each lesion was divided into two regions; one part was treated with 0...

Treatment of pyoderma gangrenosum (PG) remains a challenge, and there are currently no specific or uniformly effective therapies. Although widespread or rapidly progressive disease often requires systemic treatment, localised and mild lesions may be effectively controlled with topical agents. The most frequently applied topical drugs are corticosteroids and calcineurin inhibitors. Recently, a patient with idiopathic PG of the lower limb was successfully treated with topical timolol and collagenase. Here, we report a case of a patient with collagenous colitis, ankylosing spondylitis and periumbilical PG...

PURPOSE: β-adrenergic receptor antagonists (β-blockers) used in the treatment of glaucoma are an often-overlooked source of systemic adverse events. Ophthalmic timolol has been associated with severe systemic adverse events including numerous cases resulting in death. In recent years the number of fixed-dose combination therapies for glaucoma has grown rapidly, and among available combination therapies only the nonselective β-blocker timolol is used as the β-blocker component. METHODS: A population-based study was conducted in Ontario, Canada between January 1, 2001 and December 31, 2012 to assess the shift to combination therapies in the management of glaucoma, and to investigate the impact of this shift on the relative use of selective and nonselective β-blockers in patients with this disease...
