The Controlled Substances Act is the federal statute that regulates the manufacture and distribution of controlled substances such as hallucinogens, narcotics, depressants, and stimulants. The Act categorizes drugs into five classifications or “schedules” based on their potential for abuse, status in international treaties, and any medical benefits they may provide. Generally speaking, drugs included in Schedule 1 are the most strictly regulated, because they are deemed to have no medical value. Some examples of drugs and their classifications are:
Schedule 1: Ecstasy, LSD, and heroin. Marijuana is also considered a Schedule 1 drug, despite studies finding it to have medical uses.
Schedule 2: Cocaine and methamphetamine.
Schedule 3: Anabolic steroids, ketamine, testosterone.
Schedule 4: Ambien, Xanax, and Valium.
Schedule 5: Lyrica and cough suppressants.
Answer:
The correct answer will be option D- blocking Cl channel.
Explanation:'
Quinidine is a stereoisomer of quinine derived from the bark of Cinchona plants which is used in the medication of the heart as class I antiarrhythmic agent. This alkaloid decreases the automaticity and increases the duration of the cellular action potential of the heart.
This alkaloid acts by blocking the neurotransmission through blocking of sodium and potassium channels responsible for the depolarization in non-nodal tissues like atrial cells, ventricular cells. This decrease in the neurotransmission of an action potential depends on the Ca⁺² ions and the quinidine can also act by blocking the Ca⁺² channels as well as B adrenergic receptor.
Thus, option D-blocking Cl channel is the correct answer.
