A 3.75-cm (1.5-inch), 21-gauge needle is generally used, but obese individuals may require a 6.5-cm (2.5-inch) needle to ensure that the drug is indeed injected intramuscularly and not subcutaneously. [6] Haloperidol decanoate is provided in the form of 50 or 100 mg/mL oil solution of sesame oil and benzyl alcohol in ampoules or pre-filled ...
Relugolix is a selective antagonist of the gonadotropin-releasing hormone receptor (GnRHR), with a half-maximal inhibitory concentration (IC 50) of 0.12 nM. [1] [8] [9] A dosage of relugolix of 40 mg once per day has been found to suppress estradiol levels to postmenopausal levels (<20 pg/mL) within 24 hours in premenopausal women. [1]
25–50 mg/day Enzalutamide: Xtandi: Antiandrogen: Oral: 160 mg/day GnRH analogue: Various: GnRH modulator: Various: Variable Elagolix: Orilissa: GnRH antagonist: Oral: 150 mg/day or 200 mg twice daily Finasteride: Propecia: 5αR inhibitor: Oral: 1–5 mg/day Dutasteride: Avodart: 5αR inhibitor: Oral: 0.25–0.5 mg/day Progesterone: Prometrium ...
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
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).
Depot injections can be created by modifying the drug molecule itself, as in the case of prodrugs, or by modifying the way it is administered, as in the case of oil/lipid suspensions. Depot injections can have a duration of action of one month or greater and are available for many types of drugs, including antipsychotics and hormones .
The first six characters of the GPI define the therapeutic class code, the next two pairs the drug name, and the last four define route, dosage or strength. For example GPI 58-20-00-60-10-01-05 is for the drug nortriptyline HCl cap 10 mg (an antidepressant ) and can be further classified as follows: [ 1 ]
The maximum tolerable dose (MTD) information is necessary to be able to design such groups and therefore dose-ranging studies are usually designed after the availability of MTD information. [1] The main goal of a dose-ranging study is to estimate the response vs. dose given, so as to analyze the efficacy and safety of the drug.
