Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Povidone-iodine (PVP-I), also known as iodopovidone, is an antiseptic used for skin disinfection before and after surgery. [1] [2] It may be used both to disinfect the hands of healthcare providers and the skin of the person they are caring for. [2] It may also be used for minor wounds. [2] It may be applied to the skin as a liquid, an ointment ...
PVPP is a highly cross-linked version of PVP, making it insoluble in water, though it still absorbs water and swells very rapidly generating a swelling force. This property makes it useful as a disintegrant in tablets. PVPP can be used as a drug, taken as a tablet or suspension to absorb compounds (so-called endotoxins) that cause diarrhea.
It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2] It is the precursor to polyvinylpyrrolidone (PVP), an important synthetic material. The NVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives. [2]
α-Pyrrolidinopentiophenone (α-PVP), also known as α-pyrrolidinovalerophenone, O-2387, β-keto-prolintane, prolintanone, [2] [3] or desmethylpyrovalerone, is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug and often consumed for recreational reasons.
Cialis Drug Interactions. Tadalafil side effects aren’t the only concern when taking this drug. As mentioned, Cialis can interact with other PDE5 inhibitors for ED, as well as medications ...
However, it does act as a high affinity antagonist of the histamine H 1 receptor [24] and is a low to moderate affinity antagonist of the dopamine D 2, serotonin 5-HT 2, and α 1-adrenergic receptors. [3] [23] H 1 receptor antagonism accounts for its antihistamine effects and associated sedative side effects.
Primidone, sold under various brand names (including Mysoline), is a barbiturate medication that is used to treat partial and generalized seizures [7] and essential tremors. [8] It is taken by mouth. [7] Its common side effects include sleepiness, poor coordination, nausea, and loss of appetite. [7] Severe side effects may include suicide and ...
