The formulation combines Pentobarbital Sodium 25 mg and Pyrilamine Maleate 23 mg in rectal suppositories, designed to deliver therapeutic effects through rectal administration. This solid dosage form is inserted into the rectum, where it dissolves or melts, allowing the active ingredients to be absorbed into the bloodstream for systemic effects.

Pentobarbital Sodium is a barbiturate with sedative and hypnotic properties. It acts by depressing the central nervous system (CNS), leading to sedation, hypnosis, and anticonvulsant effects. Pentobarbital enhances the inhibitory action of gamma-aminobutyric acid (GABA) by prolonging the opening of chloride channels, resulting in decreased neuronal excitability.

Pyrilamine Maleate is an antihistamine that blocks histamine H1 receptors. By inhibiting histamine action, it alleviates symptoms associated with allergic reactions such as itching, sneezing, and nasal congestion. Additionally, Pyrilamine possesses mild anticholinergic and sedative effects, which can contribute to its therapeutic profile.

The combination of these two agents may be utilized when both sedative and antihistaminic effects are desired. Rectal administration is particularly beneficial for patients who are unable to take medications orally due to nausea, vomiting, difficulty swallowing, or when rapid absorption is required without the involvement of the gastrointestinal tract.

For prescribers, it is important to consider patient-specific factors such as age, weight, renal and hepatic function, and potential drug interactions. Monitoring is recommended for signs of excessive CNS depression, respiratory function, and anticholinergic side effects. Caution should be exercised in prescribing this formulation to patients with a

Pentobarbital sodium and pyrilamine maleate rectal suppositories are a compounded formulation designed to deliver medication through rectal administration. This method allows for the medication to be absorbed into the bloodstream, providing systemic effects. Pentobarbital is a barbiturate that acts as a central nervous system depressant, often used for its sedative and hypnotic properties. Pyrilamine maleate is an antihistamine that can help alleviate allergic symptoms and has sedative effects as well. Together, these compounds may be used to manage conditions requiring sedation and relief from allergic symptoms.

When considering the use of pentobarbital sodium and pyrilamine maleate rectal suppositories, it is crucial to be aware of potential drug interactions. Pentobarbital, as a barbiturate, can interact with a wide range of medications due to its ability to induce hepatic enzymes, which can alter the metabolism of other drugs. This can lead to decreased efficacy or increased toxicity of concomitant medications. For instance, pentobarbital may reduce the effectiveness of anticoagulants like warfarin, oral contraceptives, and certain anticonvulsants by increasing their metabolism. Additionally, combining pentobarbital with other central nervous system depressants, such as benzodiazepines, opioids, or alcohol, can result in enhanced sedative effects, leading to profound sedation, respiratory depression, or even coma.

Pyrilamine maleate, as an antihistamine, can also interact with other medications. It may enhance the sedative effects of other central nervous system depressants, including alcohol, benzodiazepines, and opioids. Additionally, pyrilamine can interact with monoamine oxidase inhibitors (MAOIs), potentially leading to increased anticholinergic effects or hypertensive crisis. Patients taking medications with anticholinergic properties, such as certain antidepressants or antipsychotics, should use pyrilamine with caution, as it may exacerbate anticholinergic side effects like dry mouth, urinary retention, or constipation.

For both patients and prescribers, it is essential to review the patient's current medication regimen, including over-the-counter drugs and supplements, to identify potential interactions before starting treatment with pentobarbital sodium and pyrilamine maleate rectal suppositories. Patients should be advised to avoid alcohol and other central nervous system depressants while using this formulation. Additionally, prescribers should consider the patient's overall health status, including liver function, as hepatic impairment may affect drug metabolism and increase the risk of adverse effects.

Pentobarbital Na 25 mg Pyrilamine Maleate 23 mg Rectal Suppositories are a compounded medication designed to deliver therapeutic effects through rectal administration. This formulation combines two active ingredients: Pentobarbital Sodium and Pyrilamine Maleate, each contributing to the overall efficacy of the treatment. The suppository is a solid dosage form that, once inserted into the rectum, dissolves or melts at body temperature, allowing the active ingredients to be absorbed either locally or systemically, depending on the intended therapeutic effect.

Pentobarbital Sodium is a barbiturate that acts as a central nervous system depressant. It works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits nerve transmission in the brain, leading to sedation, hypnosis, and anticonvulsant effects. This makes Pentobarbital effective in managing conditions that require sedation or seizure control. When administered rectally, Pentobarbital can provide a rapid onset of action, which is particularly beneficial in situations where oral administration is not feasible or when a quick therapeutic response is needed.

Pyrilamine Maleate is an antihistamine that blocks the action of histamine, a substance in the body that causes allergic symptoms. By inhibiting histamine receptors, Pyrilamine helps alleviate symptoms such as itching, swelling, and rashes. Additionally, Pyrilamine has sedative properties, which can complement the effects of Pentobarbital, providing a synergistic effect that enhances the overall sedative and calming effects of the formulation.

The rectal route of administration offers several advantages, including bypassing the gastrointestinal tract, which can be beneficial for patients with nausea, vomiting, or difficulty swallowing. It also allows for the avoidance of first-pass metabolism in the liver, potentially leading to more efficient absorption and utilization of the medication. This can result in a more predictable pharmacokinetic profile and improved therapeutic outcomes.

For prescribers, it is important to consider the specific needs of the patient when choosing this formulation. Factors such as the patient's ability to tolerate rectal administration, the urgency of the therapeutic effect, and any potential interactions with other medications should be taken into account. Additionally, the combination of Pentobarbital and Pyrilamine should be used with caution in patients with a history of substance abuse, respiratory depression, or other contraindications to barbiturates or antihistamines.

Patients using this formulation should be instructed on the proper technique for inserting the suppository to ensure optimal absorption and effectiveness. It is also important for patients to be aware of potential side effects, such as drowsiness, dizziness, or allergic reactions, and to contact their healthcare provider if they experience any adverse effects or have concerns about their treatment.
