A tablet is a solid dosage form of medication that contains one or more active ingredients. Tablets typically come in various shapes, such as round, oval, or oblong, and they may or may not be marked with a line for splitting. They are designed to be swallowed whole and dissolve in the stomach, releasing the medication for absorption into the bloodstream. Tablets are commonly used to deliver a wide range of medications, including pain relievers, antibiotics, vitamins, and treatments for chronic conditions like hypertension or diabetes.

Cough medicine is a liquid or syrupy medication used to relieve coughing. It often contains ingredients that calm the throat and reduce the urge to cough. Cough medicines are taken orally and come in various formulations, including those for dry coughs and chesty coughs, depending on the symptoms they are designed to treat.

An antacid is a type of medication that helps neutralize stomach acid to ease symptoms of heartburn, indigestion, and acid reflux. Antacids work by raising the pH level in the stomach, reducing acidity and providing quick relief from discomfort.

An ointment is a smooth, greasy substance applied to the skin to treat various conditions or provide relief. It often contains medication or other active ingredients to help heal wounds, reduce inflammation, soothe irritation, or directly deliver treatment for skin issues. Ointments are thicker and more moisturizing than creams or lotions, making them effective for dry, cracked, or damaged skin.
