155 results about "Onset of action" patented technology

Onset of action is the duration of time it takes for a drug's effects to come to prominence upon administration. With oral administration, it typically ranges anywhere from 20 minutes to over an hour, depending on the drug in question. Other methods of ingestion such as smoking or injection can take as little as seconds to minutes to take effect. The determination of the onset of action, however, is not completely dependent upon route of administration. There are several other factors that determine the onset of action for a specific drug, including drug formulation, dosage, and the patient receiving the drug.

Production method of environment-friendly floor cushion coat

The invention provides a method for preparing an environment-friendly floor board underlayer. The underlayer is prepared by firmly covering a composite catalyst material on a flaky adsorbing filter material. Only by evenly paving the environment-friendly floor board underlayer under a floor board so that the back side of the floor board is contacted with the environment-friendly floor board underlayer closely, the environment-friendly floor board underlayer can clear off harmful gases such as formaldehyde, benzene and the like and off flavor generated and released by the floor board and auxiliary materials, prevent damp and humidify, reject milden and rot, kill and inhibit bacteria, expel insects and prevent moths, increase vitamin-anions and far infrared rays in the air, and reduce the harm of dust mites and respirable particles. The environment-friendly floor board underlayer is advantageous to keep body healthy, prevent floor board form polluting, and prolong the service life of the floor board. The use is simple and convenient without professional constructions, the purification lasts without rebound, and the effect is fast and thorough; and experimental detections show that the degradation rate of the formaldehyde within 24 hours reaches 99 percent, the degradation rate of the benzene within 24 hours reaches 92 percent, the antibacterial rate is 99 percent, the mold prevention is at a zero level, the insect expelling rate is 92.8 percent, and the acute property is is actually at a nontoxic level by oral toxicity test.

Phosphoryl carboxylic acid propofol ester derivative and preparation method thereof

The invention relates to a phosphoryl carboxylic acid propofol ester derivative which has the general formula (I). The method comprises the following steps: propofol reacts with 2-halogenated carboxylic acid and a derivative thereof by alkali to obtain corresponding ester and then the product reacts with phosphoric acid or thiophosphoric acid and the derivative thereof by dissolvent to obtain a water-soluble product or the propofol reacts with a 2-halogenated carboxylic acid phosphate ester derivative by the alkali to obtain the corresponding ester and then the ester is catalyzed, hydrogenated and salified to obtain the water-soluble product (I). The preparation method has mild reaction condition, high yield, simple operation and industrialized prospect, and a prepared oral preparation has the characteristics of high bioavailability, rapid absorption, high stability, and the like; and auxiliary materials with safety defects, such as a surface active agent, and the like can not be added into the prepared injection, thereby improving the stability of the preparation, reducing or removing injection pain, increasing the compliance of patients, overcoming the defects of propofol emulsion and having the advantage of obvious effect. The invention has the structural general formula (I).
