Effervescent tablet
Effervescent Tablet
An Effervescent tablet (/ɪˈfɜːrvɪsənt/ 'tab-let') is a type of Pharmaceutical dosage form that is designed to dissolve in water before it is ingested. The term "effervescent" comes from the Latin word "effervescere", which means "to boil up" or "bubble up", referring to the release of gas when the tablet is dissolved in water.
History
Effervescent tablets were first introduced in the 19th century by the Pharmaceutical industry. They were initially used for the delivery of Aspirin and Antacids, but their use has since expanded to include a wide range of active pharmaceutical ingredients.
Composition
Effervescent tablets are composed of an Active pharmaceutical ingredient, an Acid, and a base. The acid and base react to produce carbon dioxide when the tablet is dissolved in water, which gives the solution its characteristic fizz. Common acids used in effervescent tablets include Citric acid and Tartaric acid, while common bases include Sodium bicarbonate and Potassium bicarbonate.
Advantages
Effervescent tablets offer several advantages over other dosage forms. They are easy to swallow, making them suitable for patients who have difficulty swallowing solid dosage forms. They also dissolve quickly in water, allowing for rapid absorption of the active ingredient. In addition, the fizzing action can make taking medication more enjoyable, which can improve patient compliance.
Disadvantages
One of the main disadvantages of effervescent tablets is that they are more expensive to produce than other dosage forms. They also require special packaging to protect them from moisture, which can cause them to deteriorate. In addition, some patients may find the fizzing action unpleasant.
