Penbutolol is a new beta-adrenergic blocking drug approved for the treatment of hypertension. It is a noncardioselective beta-blocker and has intrinsic sympathomimetic activity. Penbutolol is marketed under the trade names Levatol, Levatolol, Lobeta, Paginol, Hostabloc, Betapressin. Penbutolol acts on the β1 adrenergic receptors in both the heart and the kidney. When β1 receptors are activated by catecholamines, they stimulate a coupled G protein that leads to the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP). The increase in cAMP leads to activation of protein kinase A (PKA), which alters the movement of calcium ions in heart muscle and increases the heart rate. Penbutolol blocks the catecholamine activation of β1 adrenergic receptors and decreases heart rate, which lowers blood pressure. Levatol (Penbutolol) is indicated in the treatment of mild to moderate arterial hypertension. It may be used alone or in combination with other antihypertensive agents, especially thiazide-type diuretics.
Timolol maleate (ISTALOL) is a non-selective beta-adrenergic receptor blocking agent. Timolol maleate is a beta1 and beta2 (non-selective) adrenergic receptor blocking agent that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. In its opthalmic form, Timolol maleate, is used to treat open-angle and occasionally secondary glaucoma. Timolol maleate, when applied topically to the eye, has the action of reducing elevated, as well as normal, intraocular pressure, whether or not accompanied by glaucoma. Elevated intraocular pressure is a major risk factor in the pathogenesis of glaucomatous visual field loss and optic nerve damage. Timolol maleate ester is a Timolol maleate specified impurity E [EP]. Timolol impurities are used for ANDA filling/DMF filling and genotoxic study.
(R)-Timolol is the (R)-enantiomer of non-selective Beta antagonist Timolol. (R)-Timolol is a ß-adrenergic blocking agent that binds only to nonspecific sites in the particulate fraction of the heart, lungs, and brain. (R)-Timolol is an antihypertensive agent that increases ocular blood flow and reduces intraocular pressure. (R)-Timolol is one of the impurities in commercial formulation of (S)-Timolol.

(+)-Fluprostenol is the optically active enantiomer of fluprostenol. It is a potent and highly selective prostaglandin F2-alpha (FP) receptor agonist. (+)-Fluprostenol corrected corpora lutea persistence in the mares without significant clinical side effects. It was also an effective at inducing parturition in alpacas.
