Why buffer tablet is more suitable than sodium salt of aspirin?

Buffer tablets are more suitable than sodium salt of aspirin because they help maintain a neutral pH in the stomach, reducing the risk of gastric irritation commonly associated with aspirin. The buffering agents can also enhance the stability and solubility of the active ingredient, leading to improved absorption and efficacy. Additionally, buffer tablets minimize the potential for gastrointestinal side effects, making them a safer option for long-term use.
