	~~== History ==~~		'''Posizolid''' is a synthetic antibiotic belonging to the [[oxazolidinone]] class, which is used to treat infections caused by [[Gram-positive bacteria]]. It is particularly effective against [[methicillin-resistant Staphylococcus aureus]] (MRSA) and [[vancomycin-resistant Enterococcus]] (VRE).
	Posizolid ~~was first synthesized by~~ [[~~AstraZeneca~~]], ~~a British~~-~~Swedish multinational pharmaceutical and biopharmaceutical company~~. ~~The drug~~ is ~~currently in Phase II of clinical trials, where it is being tested for its safety~~ and ~~efficacy in treating bacterial infections~~.

	== Mechanism of Action ==		==Mechanism of Action==
	~~Like other oxazolidinones,~~ Posizolid works by inhibiting [[protein synthesis]] ~~in bacteria~~. It ~~does this by binding~~ to the bacterial [[ribosome]], preventing the formation of ~~a functional~~ 70S-initiation complex, which is essential for ~~the~~ bacterial ~~protein synthesis~~.		Posizolid works by inhibiting bacterial [[protein synthesis]]. It binds to the 50S subunit of the bacterial [[ribosome]], preventing the formation of the 70S initiation complex, which is essential for bacterial translation. This action is bacteriostatic against most organisms but can be bactericidal against certain strains of [[Streptococcus]].

	== ~~Clinical Trials~~ ==		==Pharmacokinetics==
	~~The Phase II clinical trials for~~ Posizolid ~~are currently ongoing~~. ~~These trials aim to determine~~ the drug~~'s safety, tolerability,~~ and ~~efficacy~~ in ~~patients with bacterial infections. The results of these trials will determine whether Posizolid will proceed to Phase III trials~~.		Posizolid is well absorbed orally, with a bioavailability of approximately 90%. It is widely distributed in body tissues and fluids, including the [[central nervous system]]. The drug is metabolized in the liver and excreted primarily in the urine.

	== ~~Potential~~ Uses ==		==Clinical Uses==
	~~If approved,~~ Posizolid ~~could be~~ used to treat a variety of ~~bacterial~~ infections, including ~~those caused by~~ [[~~methicillin-resistant Staphylococcus aureus~~]] ~~(MRSA),~~ [[~~vancomycin-resistant enterococci~~]] ~~(VRE), and multi-drug resistant~~ [[~~tuberculosis~~]].		Posizolid is used to treat a variety of infections, including:
			* [[Skin and soft tissue infections]]
			* [[Pneumonia]]
			* [[Bacteremia]]

	~~== Side Effects ==~~		It is often reserved for use in cases where other antibiotics are ineffective due to resistance.
	~~As with all drugs, Posizolid may cause side effects. The most common side effects observed~~ in ~~clinical trials include nausea, vomiting, and diarrhea. More serious side effects, such as liver toxicity, have also been reported~~.

	== ~~See Also~~ ==		==Side Effects==
			Common side effects of Posizolid include:
			* [[Nausea]]
			* [[Diarrhea]]
			* [[Headache]]

			Serious side effects can include [[myelosuppression]], [[peripheral neuropathy]], and [[lactic acidosis]].

			==Resistance==
			Resistance to Posizolid is relatively rare but can occur through mutations in the 23S rRNA of the bacterial ribosome or through the acquisition of the cfr gene, which confers resistance to multiple antibiotic classes.
