Brolucizumab (sold, depending on part of the world, under trade names Beovu or Vsiqq), is a humanized single-chain antibody fragment for the treatment of neovascular (wet) age-related macular degeneration (AMD).The most common side effects are reduced visual acuity, cataract (clouding of the lens in the eye), conjunctival haemorrhage (bleeding at the front of the eye) and vitreous floaters (spots in the vision). The most serious side effects are blindness, endophthalmitis (an infection inside the eye), retinal artery occlusion (blockage of the artery in the retina) and retinal detachment (separation of the retina from the back of the eye).Brolucizumab was designed to attach to and block a substance called vascular endothelial growth factor A (VEGF-A). VEGF-A is a protein that makes blood vessels grow and leak fluid and blood, damaging the macula. By blocking VEGF-A, brolucizumab reduces the growth of the blood vessels and controls the leakage and swelling. History
This drug was developed by ESBATech (discovery to phase 2a), Alcon Laboratories (phase 2b), and Novartis (phase 3).Brolucizumab is U.S. Food and Drug Administration (FDA) approved in ophthalmology as Beovu.Brolucizumab successfully completed phase III development in wet age-related macular degeneration (AMD) meeting the primary efficacy endpoint of non-inferiority to aflibercept in mean change in best corrected visual acuity (BCVA) from baseline to week 48.
Chloroprocaine (trade name Nesacaine, Nesacaine-MPF) (often in the hydrochloride salt form as the aforementioned trade names) is a local anesthetic given by injection during surgical procedures and labor and delivery. Chloroprocaine vasodilates; this is in contrast to cocaine which vasoconstricts. Chloroprocaine is an ester anesthetic. Medical uses
Chloroprocaine is used for regional anaesthesia including spinal anaesthesia, caudal anaesthesia and epidural anesthesiaIt is also indicated for local anaesthesia including brachial plexus block, cervical nerve block, occipital nerve block. mandibular nerve block or maxillary nerve block for dental anesthesia, ophthalmic anesthesia via infraorbital nerve block, ulnar nerve block, paravertebral block, intercostal nerve block, sciatic nerve block, stellate ganglion block, lumbar sympathetic block and interdigital block.It is also used for obstetric anesthesia including pudendal nerve block and paracervical block.Chloroprocaine is also indicated for ocular surface anesthesia. Subarachnoid block
Chloroprocaine was developed to meet the need for a short-acting spinal anaesthetic that is reliable and has a favourable safety profile to support the growing need for day-case surgery. Licensed in Europe for surgical procedures up to 40 minutes, chloroprocaine is an ester-type local anaesthetic with the shortest duration of action of all the established local anaesthetics. It has a significantly shorter duration of action than lidocaine and is significantly less toxic. Chloroprocaine has a motor block lasting for 40 minutes, a rapid onset time of 3–5 minutes (9.6 min ± 7.3 min at 40 mg dose; 7.9 min ± 6.0 min at 50 mg dose) and a time to ambulation of 90 minutes without complications, especially lacking transient neurologic symptomatology.
