Abstract

The invention discloses a bacteriostatic and antiviral preparation taking kidney bean phytohemagglutinin as a major ingredient, and belongs to the technical field of medicines. The bacteriostatic andantiviral preparation consists of the following active components according to relative parts by weight: 0.1-1.0 part of the kidney bean phytohemagglutinin, 0.2-2.0 parts of one or two of stachyose and raffinose as well as one or more of the following active components: 0.1-0.5 part of povidone iodine, 0.1-0.3 part of polyhexylene biguanidine and 0.1-0.5 part of chlorhexidine; and in addition, a thickening agent, which is hydroxyethyl cellulose, is required. The bacteriostatic and antiviral preparation provided by the invention is concrete in components, and is capable of achieving quantitative control and guaranteeing the consistency and stability of overall quality; a concrete inhibitory effect can be achieved on bacteria, fungi and viruses; therefore, the bacteriostatic and antiviral preparation is relatively broad in antibacterial and antiviral ranges; and the product (the bacteriostatic and antiviral preparation), which is required to be preserved at low temperature, is long in preservation duration and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medicines. Background technique [0002] At present, sexually transmitted diseases (STDs), including HIV, pose a great threat to people's physical and mental health, and the abuse of antibiotics has also led to the widespread emergence of drug-resistant bacteria. For viral diseases, the problem people face is that there are many types of viruses, and some viruses mutate quickly. For example, due to the rapid mutation of HIV virus, there has been no ideal effective vaccine against HIV for many years. There is an urgent need to have broad-spectrum antibacterial and antiviral, use simple formulations for daily protection and treatment. Burns, frostbite, knife wounds, abrasions, contusions and other general trauma, disinfection with iodophor is very effective. Compared with iodine and alcohol, povidone iodine causes mild irritation and pain, is easy to be accepted by patients, and has a wide range of uses a...
