Oral Spray – A Review on Promising Drug Delivery System for Oral Cavity

Aim: This review aims to compile information related to marketed oral spray preparation along with their formulation and clinical application. Objective: The main objective of this overview is to study the marketed oral spray dosage form for treatment of different diseases and learn about its advantages over the other oral dosage forms e.g. tablet, capsule, patches etc. Description: Oral spray with Mucoadhesive polymers forms small droplets that quickly adheres to the mucosal surface and let the drug permeate into the blood circulation easily. The oral mucosa has shown promising results for the systemic absorption of many drugs owing to the highly permeable nature of the mucosal membrane. Oral sprays are very fast, the most effective and easy way to get daily dose vitamins, minerals, and other nutrients ingredients. Due to this advantage oral sprays have emerged as an effective alternative for bypassing extensive first pass effect. Conclusion: It has been a very well known fact that the oral route of administration is the most popular route of drug administration. However the drwabacks like extensive first pass metabolism and drug degradation in stomach makes this route not suitable for all drugs and thus an alternative oral drug delivery systems are necessary to explaoint benefits of oral route. Many researchers are working to develop oral spray formulations for drugs which need quick permeation followed by quick onset of action and also provide an effective alternative of conventional oral drug delivery systems.
