Can 377 pill cause dependence?
Tramadol is an opioid so upon chronic therapy, both tolerance and dependence can develop. Tolerance can be developed to the desired and undesired effects of the drug and develops at a different rate with respect to each effect.
Physical dependence usually results in withdrawal symptoms which occur if the drug is discontinued abruptly or if dose reduction is significant enough to cause these symptoms.
Symptoms include irritability, anxiety, joint pain, insomnia, nausea, vomiting, diarrhea etc. These symptoms usually occur after using the drug for several weeks.
So, this drug should not be discontinued abruptly to avoid the withdrawal symptoms and the dose should be reduced gradually with time.
Infants which are born to physically dependent mothers are also dependent and show respiratory difficulties and other warning signs.
377 pill pharmacokinetics
Absorption and Distribution: Tramadol HCL is absorbed well after oral dose and the mean absolute bioavailability after a 100mg of oral dose is 75%.
Absorption is not affected by the presence of food. Volume of distribution is 2.6 L/kg (in males) to 2.9 L/kg (in females) followed by 100 mg of Intravenous dose. Plasma protein binding is approximately 20%.
Metabolism and Excretion: after oral administration, it is extensively metabolized by cytochrome CYP2D6 and CYP3A4 pathways, and also by conjugation of the parent compound and the metabolites.
The major metabolic pathway appears to be N– and O-demethylation and glucuronidation or sulfation in the liver. One metabolite (O-desmethyltramadol) is pharmacologically active.
Tramadol metabolites are excreted primarily by the kidneys. Approximately 30% of the dose is excreted unchanged in urine whereas 60% of the dose is excreted as metabolites.
How long 377 pill stays in the system?
The elimination half-life of tramadol and its active metabolite is approximately 6-7 hours. Tramadol has a half-life of about 6.3 ± 1.4 hours and the active metabolite has a half-life of about 7.4 ± 1.4 hours.
This implies that it can take about one and a half day for the drug to be completely removed from the body.
