Abstract

The invention provides a salbutamol sulfate solution for inhalation and a preparation method thereof. The prescription of the salbutamol sulfate solution comprises salbutamol sulfate, ipratropium bromide, an isoosmotic adjusting agent, a pH adjusting agent, sodium hyaluronate, carboxymethyl chitosan oligosaccharide and water for injection. The preparation process comprises the following steps: weighing, preparing a solution, adjusting the pH value, filtering, encapsulating, carrying out quality inspection and the like. According to the prescription and the preparation method, the stability ofthe preparation can be improved, meanwhile, the preparation has a good permeation effect, the salbutamol sulfate tolerance can be improved, and the preparation can better play a role.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, in particular to a salbutamol sulfate solution for inhalation and a preparation method thereof. Background technique [0002] Salbutamol sulfate is a β2 adrenergic receptor agonist. It is a white or almost white powder. It is highly soluble in water, slightly soluble in ethanol, and almost insoluble in chloroform or ether. Its role is to relax the smooth muscle of the airway. It acts on all smooth muscles from the main trachea to the terminal alveoli, and has antagonizing effect on bronchoconstriction. It has a fast onset time, but it is prone to β2 receptor resistance. [0003] Ipratropium bromide is a quaternary ammonium compound with anticholinergic (parasympathetic) properties. Preclinical studies have shown that it inhibits vagal reflexes by antagonizing the transmitter acetylcholine released from the vagus nerve. Anticholinergic drugs prevent the intracellular increase...
