Cytochrome P450 and CYP2D6 allow codeine to undergo O-demethylation to form morphine.
Cytochrome P450 allows amphetamine to undergo oxidative deamination.
Cytochrome P450 allows phenobarbitual to undergo aliphatic hydroxylation. It then turns into an alcohol.
Cytochrome P450 allows phenytoin to undergo aromatic hydroxylation to turn into phenol.
First pass metabolism refers to the metabolism of a drug that occurs in the liver after it is absorbed from the gastrointestinal tract, before it enters systemic circulation. Phase 1 metabolism is the initial biotransformation of a drug, primarily carried out by enzymes such as cytochrome P450, to make the drug more polar and easier to eliminate from the body.
The half-life of codeine in urine typically ranges from 3 to 6 hours, but its metabolites can be detected for a longer period. Codeine itself may be detectable in urine for 1 to 3 days after use, depending on various factors such as dosage, frequency of use, and individual metabolism. However, the specific detection window can vary based on the sensitivity of the test and individual differences in metabolism.
Codeine phosphate can be detected in a person's urine for 2-4 days, and in their blood for up to 12 hours. It can be detected in a person's saliva for 1-4 days. Codeine is an ingredient in many types of cough syrup.

gr ss = gr 1/2 gr 1 = 60 mg therefore gr ss = 30 mgSo you would give 1 (30mg) tablet of codeine to fulfill the order of codeine gr ss

In the cell cycle, G1 stands for Gap 1 phase. During G1 phase, the cell grows, carries out its normal functions, and prepares for DNA replication in the S phase. It is also a checkpoint phase where the cell decides whether to proceed to the next phase of the cell cycle or enter a non-dividing state called G0.
The phase in the cell cycle where the cell grows and develops is called the G1 phase, or Gap 1 phase. During this phase, the cell increases in size, synthesizes proteins, and produces organelles, preparing itself for DNA replication. It is a crucial stage for cellular function and metabolism, as the cell assesses its environment and ensures it is ready to enter the S phase, where DNA synthesis occurs.
Tylenol #1, #2, #3 and #4 formulations contain 8mg, 15mg, 30mg and 60mg of codeine respectively.
