2.3 H2 Blockers

H2 blockers‚ or histamine-2 receptor antagonists‚ are medications that reduce stomach acid production by blocking histamine signals to parietal cells. Common H2 blockers include cimetidine‚ ranitidine‚ and famotidine. These drugs are effective in treating peptic ulcers‚ gastroesophageal reflux disease (GERD)‚ and Zollinger-Ellison syndrome. They work faster than antacids but are less potent than proton pump inhibitors (PPIs). H2 blockers are available in both prescription and over-the-counter (OTC) forms‚ offering quick relief from heartburn and indigestion. Side effects are generally mild and include headache‚ dizziness‚ or diarrhea; Long-term use requires monitoring for potential risks‚ such as increased susceptibility to infections. H2 blockers are a reliable option for managing acid-related gastrointestinal disorders‚ providing a balance between efficacy and safety for many patients. Their role in therapy is well-established‚ making them a cornerstone in gastrointestinal treatment.

2.4 Laxatives

Laxatives are medications used to treat constipation by promoting bowel movements. They work by either softening stools‚ increasing stool bulk‚ or stimulating intestinal motility. Common types include osmotic laxatives‚ such as polyethylene glycol‚ which draw water into the intestines‚ and stimulant laxatives‚ like senna and bisacodyl‚ which enhance intestinal contractions. Bulk-forming laxatives‚ such as psyllium‚ increase fiber intake to soften stools. Laxatives are available in various forms‚ including oral tablets‚ liquids‚ and suppositories. While effective for short-term relief‚ prolonged use can lead to dependence or electrolyte imbalances. It’s important to use laxatives as directed and consider dietary changes for long-term management. They are a crucial option for managing constipation and restoring regular bowel function in both acute and chronic cases‚ offering a range of mechanisms to suit different needs and preferences.

2.5 Antiemetics

Antiemetics are drugs designed to prevent or alleviate nausea and vomiting‚ commonly associated with conditions like motion sickness‚ chemotherapy‚ and postoperative recovery. They function by targeting various pathways in the central nervous system and the gastrointestinal tract. Common classes include dopamine antagonists‚ such as metoclopramide‚ which block nausea signals in the brain‚ and serotonin antagonists‚ like ondansetron‚ effective in chemotherapy-induced nausea. Antihistamines‚ such as dimenhydrinate‚ are used for motion sickness. Antiemetics are available in oral‚ injectable‚ and transdermal forms‚ offering flexibility for different patient needs.
