Step 1: Understanding the Problem:
'Saheli' is an innovative oral contraceptive pill for females, developed indigenously in India by the Central Drug Research Institute (CDRI) located in Lucknow.
Step 2: Approach and Formula:
Evaluate the distinct pharmacological characteristics, dosage schedule, safety profile, and efficacy of 'Saheli' against the given statements.
Step 3: Detailed Explanation:
Let's analyze the properties of 'Saheli' based on standard literature:
- Composition: It is famously a non-steroidal preparation (containing centchroman), unlike standard daily birth control pills which contain steroid hormones (estrogen/progesterone). Statement (A) is true.
- Dosage: Due to its unique mechanism, it is prescribed as a 'once-a-week' pill. Statement (B) is true.
- Safety: Being non-steroidal, it is renowned for causing very few to almost no side effects. Statement (D) is true.
- Efficacy: Despite its low dosage frequency, it exhibits a very high contraceptive value (high effectiveness in preventing pregnancy). Therefore, the claim that it has a "low contraceptive value" is factually incorrect.
Step 4: Final Answer:
The statement "It has low contraceptive value" is NOT true.
