Cefovecin is an antibiotic of the cephalosporin class, licensed for the treatment of skin infections in cats and dogs. It is marketed by Zoetis under the trade name Convenia. It is used to treat skin infections caused by Pasteurella multocida in cats, and Staphylococcus intermedius and Streptococcus canis in dogs. The advantage of using a long ...
Bioavailability is 91% at the standard subcutaneous dose but 24% at the standard oral dose; the standard oral dose is higher to partially compensate for incomplete bioavailability. [ 5 ] [ 18 ] It binds to plasma proteins at a rate of 99.5%; it has a low volume of distribution (9 L/kg) and is thus not extensively absorbed.
In other sustained release formulations the matrix swells to form a gel through which the drug exits. Another method by which sustained release is achieved is through an osmotic controlled-release oral delivery system , where the active compound is encased in a water-permeable membrane with a laser drilled hole at one end.
Dosage forms vary depending on the method/route of administration, which can include many types of liquid, solid, and semisolid forms. Common dosage forms include tablets, capsules, drinks, and syrups, among others. A combination drug (or fixed-dose combination; FDC) is a product that contains more than one active ingredient (e.g., one tablet ...
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes).This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
Modified-release dosage is a mechanism that (in contrast to immediate-release dosage) delivers a drug with a delay after its administration (delayed-release dosage) or for a prolonged period of time (extended-release [ER, XR, XL] dosage) or to a specific target in the body (targeted-release dosage). [1] Sustained-release dosage forms are dosage ...
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
