- Betaxolol is an effective ocular antihypertensive agent, pharmacologically classified as a cardioselective beta-blocker. Its mode of action in reducing intraocular pressure is similar to that of non-selective blockers, suppressing the flow of aqueous humor. The extent of occupation, in the systemic circulation, of the beta 1-adrenoceptor of betaxolol when applied topically is smaller than that of non-selective blockers and the occupation of the beta 2 receptor is insignificant, providing a better safety profile in patients with cardiopulmonary disease . Experimental studies have revealed that this drug targets the retina after topical administration and exhibits L-type dependent calcium channel blocking activity, which likely allows betaxolol to improve retinal perfusion and serve as a recommended neuroprotective agent in various forms of glaucoma . The most frequent adverse reaction to betaxolol is burning after administration, which is minimized by an ocular suspension with a reduced…Based on the transduction pathway presented above, what type of receptor is the beta-3 adrenergic receptor? Question 15 options: a) It is a voltage-dependent ion channel. b) It is a G protein-coupled receptor (GPCR). c) It is a G protein. d) It is a protein kinase. e) It is a receptor tyrosine kinase (RTK).Using the coding techniques described in this chapter, carefully read through the case study and determine the most accurate CPT code(s) and HCPCS code(s) and modifier(s), if appropriate. Harrison Parker, a 69-year-old right-handed male, was referred to me for a neurologic evaluation by his internist, Dr. Brady, for a tremor that has been present for approximately 20 years. Patient states that the tremor began insidiously and has progressed gradually. It now involves both hands and affects his handwriting, drinking coffee and other liquids with a cup, and general work that requires manual dexterity. Other people occasionally notice a tremor in his head. He is otherwise healthy, although he feels his balance is not quite as good as it used to be. A glass of beer or wine markedly decreases the tremor severity. His mother and daughter also have tremor. Patient denies smoking. On examination, he has a rather regular tremor of approximately 8 cycles per second (Hz) with his hands extended…
