What is Chloropyramine Hydrochloride?
Chloropyramine Hydrochloride is a medication that belongs to a class of drugs known as antihistamines[1]. Antihistamines work by blocking the effects of histamine, a substance in the body that causes allergic symptoms. The medication is marketed under the brand name Synopen, specifically as “Synopen 20 mg/2 ml otopina za injekciju,” which translates to “Synopen 20 mg/2 ml solution for injection” in English[1].
Medical Uses
While the specific medical uses are not explicitly stated in the provided clinical trial data, antihistamines like Chloropyramine Hydrochloride are typically used to treat various allergic conditions. These may include:
- Allergic rhinitis (hay fever)
- Urticaria (hives)
- Allergic skin reactions
- Itching associated with various conditions
It’s important to note that the exact indications may vary depending on the country and specific formulation[1].
How is it Administered?
Chloropyramine Hydrochloride, in the form mentioned in the clinical trial data, is administered intravenously. This means it is given directly into a vein[1]. Intravenous administration allows the medication to enter the bloodstream quickly, which can be beneficial in situations requiring rapid relief of symptoms.
Dosage Information
According to the clinical trial data, the maximum daily dose of Chloropyramine Hydrochloride is 0.2 mg/kg (milligrams per kilogram of body weight)[1]. This means the dose is adjusted based on the patient’s weight. For example, a person weighing 70 kg (about 154 pounds) would receive a maximum daily dose of 14 mg.
The maximum treatment period mentioned in the data is 11 time units, though the specific unit (days, weeks, etc.) is not specified[1]. Always follow your healthcare provider’s instructions regarding dosage and duration of treatment.
Current Clinical Trial
It’s important to note that Chloropyramine Hydrochloride is mentioned as part of a clinical trial for a different treatment. The main focus of this trial is not on Chloropyramine Hydrochloride itself, but on a cell therapy for a rare skin condition called epidermolysis bullosa[1]. Chloropyramine Hydrochloride is likely included as a supportive medication in this trial, possibly to manage allergic reactions or itching associated with the condition or treatment.
