hello Mr Arora! i read your query and i want you to know that constipation is not just the medicines use. You need to modify lifestyle, diet, sleep habits, and then medicines will be help. take alot of fluids, increase fiber in diet, use soft diet, avoid alcohol and all other stimulants to avoid excacerbations. see the gastro enterologist to rule out Gastro intestinal morbidities like IBS etc to be on the safer road as age of 62 increase the odds. You can try following medications Bulk-forming agents (fibers; eg, psyllium): arguably the best and least expensive medication for long-term treatment Emollient stool softeners (eg, docusate): Best used for short-term prophylaxis (eg, postoperative) Rapidly acting lubricants (eg, mineral oil): Used for acute or subacute management of constipation Prokinetics (eg, tegaserod): Proposed for use with severe constipation-predominant symptoms Stimulant laxatives (eg, senna): Over-the-counter agents commonly but inappropriately used for long-term treatment of constipation There are newer options for constipation treatment like Prucalopride, a prokinetic selective 5-hydroxytryptamine-4 (5-HT4) receptor antagonist that stimulates colonic motility and decreases transit time The osmotic agents lubiprostone and linaclotide, which are FDA approved for chronic idiopathic constipation, constipation caused by irritable bowel syndrome, and (in the case of lubiprostone) opioid-induced constipation in adults with chronic, noncancer pain hope i was of some help. If the problem persists see the gastro enterologist near by to be on the safr roads regards Dr S Khan
