Definition 

Sevoflurane is a highly fluorinated, nonflammable, and sweet-smelling methyl isopropyl that works as an inhalational drug for the maintenance of general anesthesia. It is the second most volatile anesthetic that features the fastest onset after desflurane. 

Its offset is also faster than other agents and more similar to older agents. Sevoflurane and the isoflurane tissue blood partition coefficients are similar, making it half as soluble in blood as isoflurane. 

Sevoflurane Forms and Specifications

Most importantly, sevoflurane is a DMF drug, and its CAS number is 28523-86-6. The drug features 1,1,1,3,3,3-hexafluoroisopropanol and fluoromethyl to make up its two alkyl groups. This statement explains why it is both an ether and an organofluorine compound. 

In any case, sevoflurane derives most of its features from its 2-methoxypropane. Combining the central glass features makes it one of the most popular volatile anesthetic options in China and the world. Combining the central glass features makes it one of China’s most popular volatile anesthetic options and the world. Besides, it has an excellent safety record and works best for outpatient anesthesia.  

General Uses

This drug is one of the most popular volatile anesthetic agents and veterinary medicine that can work across all ages. It can work together with desflurane to replace halothane and isoflurane in modern anesthesia treatment. However, it would be best to administer it with a mixture of oxygen and nitrous oxide. 

Sevoflurane features an excellent safety record, but FDA is reviewing it for any potential hepatotoxicity. All the same, it can be the best alternative for mask induction since it features fewer mucous membranes’ irritation. 

The drug is generally effective for induction and maintenance of sleep before surgery. It would be best to mention that the medication causes delirium and agitation when the patient wakes up. Yet, research does not explain how to prevent this condition. 

Mechanism of Action

Since it is a general anesthetic, sevoflurane works by temporarily reducing the body’s central nervous system activities. Thus, it will result in a complete loss of body sensation. Hence, it can also affect consciousness, distress, and pain. 

Some factors to consider when deciding the dosage include the type of operation, weight, and age. In any case, the drug will send the patient to sleep smoothly and quickly. Luckily, it features a pleasant odor that makes it a better option. 

Sevoflurane is primarily a fluorinated isopropyl ether that comes with general anesthetic features. The drug usually acts by impeding neurotransmitters’ release and re-uptake at the post-synaptic level. It can also perform its function by altering ionic conductance by inducing the neurotransmitter to activate the receptor. 

It can also interact with the lipid matrix in the neuronal membranes. This step will later affect ion channels and their gating properties. Also, it can activate GABA (gamma-aminobutyric acid) receptors to hyperpolarize the cell membranes. Hence, sevoflurane can result in an increased respiratory rate, a reduction in myocardial contractility, and a general anesthetic effect. 

The patient ought to breathe in the medicine through a mask. But still, doctors can give the patient an injection to speed up its action. The sevoflurane will wear off, and the patient will wake up within a few minutes after removing the mask. It would be best to mention that children may become restless trying to wake up after using this drug.

Manufacturing Process

The sevoflurane manufacturing process features a CF3- CH(OCH2F)-CF3 preparation related to particular malonic acid compounds. The procedure should process a substituted acid compound that works as a synthetic intermediate under various reactions. 

The reaction combines R3HNOC-CH (OCH2X)-CONHR4 with R1OOC-CH(OCH2X)-COOR2 through a process where X represents an OH or a leaving group. Different but equal R1, R2, R3, R4, and nucleophilic substitution replace the leaving group. 

In general, the synthesis of sevoflurane features the fluoroalkylation of hexafluoroisopropyl alcohol. It uses HF and formaldehyde in a fuming sulfuric acid presence. Another alternative method would be through the exchange of halide reactions targeting hexafluoroisopropyloxymethyl chloride. The alternative procedure makes use of Baxter or bromine trifluoride. 

Side Effects

Some common side effects include pancreatitis, oedema, nephritis tubulointerstitial, muscle rigidity, intracranial pressure increased, dystonia, confusion, atrioventricular block, asthma, hypothermia, atrioventricular block, asthma, hypothermia, and fever. Sevoflurane might not be safe for pregnant, and breastfeeding women and there is no clear report about it. 

Sevoflurane Price

The price of sevoflurane inhalation liquid that is 100% pure varies depending on the pharmacy location. 1500 millimeters can cost about $687, while 250 millimeters can cost about $110. Above all, the price may vary from one region to another.

Where to Buy Sevoflurane in Bulk?

PharmaSources is one of the top marketplaces to supply and buy quality and bulk sevoflurane. The platform also provides helpful guides about the best active pharmaceutical ingredients suppliers and products for worldwide users. Pharmasource provides pharmaceutical refrigeration, pharmaceutical clean rooms, and pharmaceutical laboratory equipments for customers. But Pharmasource has more than that. In any case, Pharmasource has served more than 90,000 pharmacies from over 211 regions. Besides, the platform offers over 1,600,000 products in around 30 pharma supply chains.

FAQ:

How is Sevoflurane Administered?

The most common induction dose is about 1.5% to 3%. This concentration usually results in surgical anesthesia within seven to ten minutes. It would be best to increase the isoflurane concentration gradually by 0.1% to 0.25%. Also, you ought to deliver the medicine through inhalation. Above all, using hypnotics will help the patient to diminish some side effects. 

What is Faster, Desflurane or Sevoflurane?

Early and emergence recovery was faster using desflurane than sevoflurane. Nevertheless, the readiness for home discharge (intermediate recovery end-points) was faster for sevoflurane than desflurane. 

Besides, it would be best to focus on choosing an option that is safer than one that is faster. It would be best to check on the patient's condition before choosing the best option that can work for them. 

What is the MAC of Sevoflurane?

The MAC (Minimum Alveolar Concertation) for sevoflurane is about 1.71 +/- 0.07% (SE). Maintaining this MAC is crucial for preventing response movement to healthy surgical incision patients. Nevertheless, 2.07% is the most optimal anesthetic ED95 that can prevent most patients from moving.
