It is used for sedation and anaesthesia for almost all types of surgery, but is particularly well-suited for anaesthesia in patients undergoing ambulatory [ 8 ] and neurosurgery where rapid psychomotor recovery are of upmost importance. Its efficacy and utility has also been proven for sedation of patients in the intensive care unit ICU [ 9 ] and conscious sedation of patients undergoing diagnostic or invasive procedures [ 10 ].

The adverse effects of propofol are well-documented, with the most common being pain on injection. Other adverse effects are cardiovascular bradycardia, hypotension and metabolic hyperlipidaemia secondary to infusion of lipid formulation [ 11 ]. Although propofol is well-established in clinical practice, there have been a number of studies published in recent years on the clinical use and pharmacology of the drug.

All articles published after 1 January , in English, with full-text available and relating to human subjects were evaluated for relevancy. A full-text copy was obtained for all relevant publications.

A further search of the bibliographies of all relevant articles was performed also known as the snowball method to identify any relevant publications missed during the initial search. Drug Formulation Propofol is insoluble in water [ 4 ].

After a series of reports of bacterial contamination of opened ampoules, ethylenediaminetetraacetic acid EDTA; 0. The solution is isotonic, and neutral pH is achieved by adding sodium hydroxide. The pKa is A number of different formulations of propofol are currently available, produced by many different manufacturers. Most propofol formulations cause pain on injection, which is thought to be due to direct and indirect irritation of venous adventitia by free aqueous propofol through an interaction with TRPV1 and TRPA1 receptors [ 15 , 16 ].

Although this reformulation of propofol has reduced the prevalence of pain on injection during the induction of anaesthesia, it still remains a problem in clinical practice [ 18 ]. Indications, Contraindications, Drug Dosing Regimen and Adverse Effects Propofol is used for the induction and maintenance of the hypnotic component of sedation or general anaesthesia.

Its use is contraindicated in two patient categories: 1 patients with hypersensitivity to propofol or any of the components of its formulation, and 2 patients with fat metabolism disorders.

Propofol should only be administered by healthcare professionals trained in the safe care of patients undergoing general anaesthesia. Multiple propofol dosing schemes exist; however, due to considerable variability in the propofol dose necessary to achieve certain clinical endpoints, these should only be regarded as very approximate dosing guidelines.

Propofol administration should always be titrated according to clinical effect, which is part of the reason why the clinician should closely monitor the effects and adverse effects of propofol vide infra. This dose should be adjusted reduced when propofol is administered to less-fit patients undergoing general anaesthesia, such as those fulfilling the ASA physical status categories ASA 3 or 4, or when propofol is used to induce and maintain sedation in critically ill patients in the ICU.

For exact dosing guidelines, please refer to the package insert. The main adverse effects of propofol administration relate to alterations of cardiopulmonary physiology, including loss of airway reflexes, hypoventilation or even apnoea, and hypotension.

Any provider of anaesthesia should be trained in managing these adverse effects. PRIS occurs mostly in the setting of prolonged and high-dose propofol infusion administration in children.

Lastly, there are strong indications, mainly from animal studies [ 22 ] and retrospective clinical studies [ 23 ], that sedation with GABA agonistic drugs might be responsible for neurotoxicity in paediatric patients, resulting in long-term cognitive deficits; however, clinical significance of these findings is not known and further prospective studies are currently being conducted.

Pharmacokinetics PK Absorption Propofol is only suitable for intravenous use. Some researchers have tried to increase the oral bioavailability of propofol, with some success, by administering it in nanoparticles, but this application remains experimental [ 25 ]. Distribution After intravenous administration, propofol is extensively bound to the plasma proteins predominantly albumin and erythrocytes.

The free fraction is only 1. Propofol readily crosses the blood—brain barrier BBB and causes rapid loss of consciousness sometimes within the time it takes for a drug to pass through the circulation once [ 27 ].

In contrast, Rowland and Tozer explain the principles of PK in great details and often from multiple angles, so that the readers can fully appreciate how the concepts are linked together, how PK theories apply and how PK impacts pharmacology research and the drug discovery.

The exercises are challenging, but not impossible. Well, a few of them are nearly impossible, but most of them can be worked out even for someone of my background. I would love to give it a 4. I do see there are a few shortcomings in this book. Although it is very detailed, it can be too detailed for beginners, except for students who has more time.

It is best to start off with a short and easy to read introductory book. Yes, Rowland and Tozer have explained many concepts in multiple ways and this is generally good, except when you are busy.

Sometime, I just feel like: I get your point already. The Final and the real criticism is that the book can be a bit dry.

Unlike "Concepts In Clinical Pharmacokinetics", this is not a book to be breezed through. With real life examples that help understanding the math. This is a great textbook with many examples.

Math is well explained and thus, it is easier to comprehend or review concepts one thought forgotten. Came as a new book. Good quality. Worth it. Paperback Verified download.

Used for work. No complaints yet. The book arrived way ahead of schedule and in the condition promised. It has been very helpful with my classes in pharmacy school.

The content of this site is intended for health care professionals. However, the presence of the antagonist will cause the main drug to be released from the receptor regardless of the main drug's concentration, therefore all the receptors will eventually become occupied by the antagonist.

The effects of these chemicals on humans and the environment are not yet known, but to date there is no scientific evidence that they affect human health. Ruijuan Luo rated it it was ok Jun 01,
