Beta adrenergic blockers: Nonselective and beta1 selective.
Nonselective: it means combination of Alpha and Beta-- Timolol -- decreases aqueous formation lowering pressure in the eye -- it could become systemic, cardiac reseptors (heart blocking, and bradycardia) and bronchospasm.
Selective: B1 -- Betaxolol (good DOC for COPD and sthma pts) -- decreased aqueous formation lowering the pressure in the eye -- cardiac receptors (heart block, bradycardia, hypotension)
Prostaglandin Analogs: adrenal which helps w the immune response increasing aqueous outflow and open the channel of schelemm -- Latanoprost (xalatan) -Prost. -- brown pigmentation of the iris and eyelid.
