Abstract

The invention relates to a paracetamol, aminophenazone, caffeine and chlorphenamine maleate tablet and a preparation method thereof. The tablet is prepared from the following effective active ingredients: paracetamol, aminophenazone, caffeine and chlorphenamine maleate and also comprises common auxiliaries such as filler, lubricant, a disintegrating agent and an adhesive. According to the preparation method, the defects of sticking pinch, greasy pinch and the like caused by adhesive objects in the tabletting process by screening auxiliaries in the formula, and the prepared tablet is smooth and clean in appearance.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a phenammonate tablet and a preparation method thereof. Background technique [0002] Phenamine Kamin Tablets, also known as Pu Sen Min and Ke Sen Min, is a commonly used anti-cold compound preparation, which consists of acetaminophen, aminopyrine, caffeine, chlorpheniramine maleate and appropriate amount of auxiliary materials. Experiments have found that during the preparation of phenacamine tablets by wet granulation, when the materials are mixed and added to the binder, the interaction between the materials will lead to difficulty in granulation, resulting in flakes and sticking problems. The reason is that paracetamol is an organic acid, and aminopyrine is an organic base. The two react in the presence of water to form a compound that is very soluble in water. Grains are difficult, resulting in flower flakes and sticky punching problems. "Orthogonal Method Op...
