Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small. [ 2 ]
If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular and the pH shifts less with small additions of titrant near the equivalence point. For example, the titration curve for the titration between oxalic acid (a weak acid) and sodium hydroxide (a strong base) is
A commercially prepared pre-filled syringe of metaraminol for bolus use during anaesthesia, made up as 0.5 mg/mL (2.5 mg in 5 mL). Metaraminol is given intravenously as either a bolus (often 0.5–1 mg doses) or as an infusion, usually via peripheral intravenous access.
Phenylephrine, sold under the brand names Neosynephrine and Sudafed PE among others, is a medication used as a decongestant for uncomplicated nasal congestion in the form of a nasal spray or oral tablet, [5] to dilate the pupil, to increase blood pressure given intravenously in cases of low blood pressure, and to relieve hemorrhoids as a suppository.
The stakes are high, experts say, because a committee vote declaring phenylephrine ineffective as an oral decongestant could push the FDA to revoke the drug’s over-the-counter designation as ...
Rhinitis medicamentosa (or RM, also known as rebound congestion) is a condition of rebound nasal congestion suspected to be brought on by extended use of topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) and certain oral medications (e.g., sympathomimetic amines and various 2-imidazolines) that constrict blood vessels in the lining of the ...
More than one Bengal cat has slipped into the shower with their owner or snuck into the pool. British Shorthair cats also like water. They really love a faucet. They'll stare at running water for ...
Phenylephrine is an over-the-counter drug that has been used for decades to relieve congestion and stuffy nose caused by allergies or colds, and purportedly works by reducing the swelling of blood ...
