Aspirin Rectal Common Cold Uses Side Effects Dosage

aspirin rectal

Aspirin (acetylsalicylic acid) is one of the oldest and most common non-steroidal anti-inflammatory drugs (NSAIDs) used for headache, aches, and fever. Aspirin rectal is a suppository administered rectally, typically in children and adults unable to take it orally. The drug is absorbed systemically through the rectal mucous tissue and works similar to the oral drug. Aspirin rectal is available over the counter (OTC).

Aspirin inhibits cyclooxygenases (COX-1 and COX-2), essential enzymes for prostaglandin biosynthesis. Prostaglandin plays a role in inflammation, pain, and fever. Blocking prostaglandin production also inhibits thromboxane A2 release, a substance that promotes blood clotting.
