Final answer:
For a patient diagnosed with peripheral arterial disease, Pentoxifylline (Trental) or Cilostazol (Pletal) are the preferable medications as they help improve intermittent claudication and blood flow in the affected limbs. Warfarin and Dabigatran are not the primary choices for managing PAD symptoms.
Step-by-step explanation:
A patient diagnosed with peripheral arterial disease (PAD) has several medication options available for management. PAD involves the narrowing of peripheral arteries due to atherosclerosis, typically affecting the legs and causing symptoms like intermittent claudication. While aspirin alone or in combination with another antiplatelet drug (dual antiplatelet therapy, or DAPT) is often prescribed preventatively, the specific medications best suited for the management of PAD among the options listed are Pentoxifylline (Trental) and Cilostazol (Pletal). Pentoxifylline improves blood flow and has been used to treat intermittent claudication associated with PAD. Cilostazol also improves symptoms of claudication and can increase walking distances in patients with PAD. On the other hand, Warfarin (Coumadin) and Dabigatran (Pradaxa) are anticoagulants mostly used for preventing blood clots in conditions such as atrial fibrillation and after certain types of heart valve replacement, rather than specifically targeting PAD symptoms. Therefore, Pentoxifylline (Trental) or Cilostazol (Pletal) would be the most appropriate choices among the medications listed for a patient with PAD.
