Unoprostone Isopropyl is a synthetic docosanoid and a structural analogue of an inactive biosynthetic cyclic derivative of arachidonic acid, 13,14-dihydro-15-keto-prostaglandin F 2a. Although the mechanism of action is unknown, unoprostone isopropyl is believed to reduce elevated intraocular pressure by increasing the outflow of aqueous humor through the trabecular meshwork. Unoprostone isopropyl (UI) may have a local effect on Big Potassium channels and ClC-2 chloride channels, but the exact mechanism is unknown at this time. Unoprostone is used for the management of open-angle glaucoma and ocular hypertension. The therapeutic efficacy of Unoprostone can be decreased when used in combination with Celecoxib, Diclofenac, Diflunisal, Etodolac and some other drugs. Unoprostone isopropyl ophthalmic solution may gradually increase the pigmentation of the iris, cause pigment changes (darkening) to periorbital pigmented tissues and eyelashes, exacerbate active intraocular inflammation (e.g., uveitis), and cause macular edema. In clinical studies, the most common ocular adverse reactions with use of Rescula were burning/stinging, burning/stinging upon drug instillation, dry eyes, itching, increased length of eyelashes, and injection. These were reported in approximately 10–25% of patients. Ocular adverse reactions occurring in approximately 5–10% of patients were abnormal vision, eyelid disorder, foreign body sensation, and lacrimation disorder. Other adverse reactions occurred more rarely.

BETAXON™ is a trade name for levobetaxolol hydrochloride ophthalmic suspension 0.5%, which is indicated for lowering intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension. The brand name Betaxon is discontinued in USA, but generic versions may be available. Levobetaxolol is a cardioselective (beta-1¬ adrenergic) receptor-blocking agent that does not have significant membrane-stabilizing (local anesthetic) activity and is devoid of intrinsic sympathomimetic action. Animal studies suggest levobetaxolol (S-isomer) is the more active enantiomer of betaxolol (racemate).

Rosiglitazone acts as a highly selective and potent agonist at peroxisome proliferator activated receptors (PPAR) in target tissues for insulin action such as adipose tissue, skeletal muscle, and liver. It is FDA approved for the treatment of as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Inhibitors of CYP2C8 (e.g., gemfibrozil) may increase rosiglitazone levels; inducers of CYP2C8 (e.g., rifampin) may decrease rosiglitazone levels. Common adverse reactions include edema, weight gain, and headache.

Rapacuronium bromide (RAPLON), a nondepolarizing neuromuscular blocking agent, is a negative allosteric modulator of muscarinic acetylcholine receptors. Rapacuronium bromide is indicated as an adjunct to general anesthesia to facilitate tracheal intubation and to provide skeletal muscle relaxation during surgical procedures. There were no specific pharmacokinetic studies conducted to examine the drug-drug interactions of RAPLON. Due to the risk of fatal bronchospasm, it was withdrawn from the United States market less than 2 years after its FDA approval.
